A white female client is admitted to an acute care facility with a diagnosis of cerebrovascular accident (CVA). Her history reveals bronchial asthma, exogenous obesity, and iron d eficiency anemia. Which history finding is a risk factor for CVA? a. Caucasian race b. Female sex d. Bronchial asthma c. Obesity 1. Answer C. Obesity is a risk factor for CVA. Other risk factors include a history of ischemic episodes, cardiovascular disease, diabetes mellitus, atherosclerosis of the cranial vessels, hypertension, polycythemia, smoking, hypercholesterolemia, oral contraceptive use, emotional stress, family history of CVA, and advancing age. The client’s race, sex, and bronchial asthma aren’t risk factors for CVA. 2. The nurse is teaching a female client with multiple sclerosis. When teaching the client how to reduce fatigue, the nurse should tell the client to: a. take a hot bath. ` b. rest in an air-conditioned room c. increa rease the dos dose of muscle relaxants. d. avoid naps duri durin ng the day day 2. Answer B. Fatigue is a common symptom in clients with multiple sclerosis. Lowering the body temperature by resting in an air-conditioned room may relieve fatigue; however, extreme cold should be avoided. A hot bath or shower can increase body temperature, producing fatigue. Muscle relaxants, prescribed to reduce spasticity, can cause drowsiness and fatigue. Planning for frequent rest periods and naps can relieve fatigue. Other measures to reduce fatigue in the client with multiple sclerosis include treating depression, using occupational therapy to learn energy conservation techniques, and reducing spasticity. 3. A male client is having a tonic-clonic seizures. What should the nurse do first? a. Elevate the head of the bed. b. Restrain the client’s arms and legs. c. Place a tongue blade in the client’s mouth. d. Take measures to prevent injury . 3. Answer D. Protecting the client from injury is the immediate priority during a seizure. Elevating the head of the bed would have no effect on the client’s condition or safety. Restraining the client’s arms and legs could cause injury. Placing a tongue blade or other object in the client’s mouth could damage the teeth. 4. A female client with Guillain-Barré syndrome has paralysis affecting the respiratory muscles and requires mechanical ventilation. When the client asks the nurse about the paralysis, how should the nurse respond? a. “You may have difficulty believing this, but the paralysis caused by this disease is temporary.” b. “You’ll have to accept the fact that you’re permanently paralyzed. However, you won’t have any sensory loss.” c. “It must be hard to accept the permanency of your paralysis.” d. “You’ll first regain use of your legs and then your arms.” 4. Answer A. The nurse should iinform nform the client that the paralysis that accompanies Guillain-Barré syndrome is only temporary. Return of motor function begins proximally and extends distally in the legs. 5. The nurse is working on a surgical floor. The nurse must logroll a male client following a: a. laminectomy. b. thoracotomy. c. hemorrhoidectomy. d. cystectomy. 5. Answer A. The client who has had spinal surgery, such as laminectomy, must be logrolled to keep the spinal column straight when turning. The client who has had a thoracotomy or cystectomy may turn turn himse himself lf or may may be assi assist sted ed into into a comfo comfort rtab able le posi positi tion on..

A female client with a suspected brain tumor is scheduled for computed tomography (CT). What should the nurse do when preparing the client for this test?
Page 1 of 7
a. Immobilize the neck before the client is moved onto a stretcher. b. Determine whether the client is allergic to iodine, contrast dyes, or shellfish. c. Place a cap over the client’s head. d. Administer a sedative as ordered. 6. Answer B. Because CT commonly involves use of a contrast agent, the nurse should determine d etermine whether the client is allergic to iodine, contrast dyes, or shellfish. Neck immobilization is necessary only if the client has a suspected spinal cord injury. Placing a cap over the client’s head may lead to misinterpretation of test results; instead, the hair should be combed smoothly. The physician orders a sedative only if the client can’t be expected to remain still during the CT scan. 7. During a routine physical examination to assess a male client’s deep tendon reflexes, t he nurse should make sure to: a. use the pointed end of the reflex hammer when striking the Achilles tendon. b. support the joint where the tendon is being tested. c. tap the tendon slowly and softly d. hold the reflex hammer tightly. 7. Answer B. To prevent the attached muscle from contracting, the nurse should support the joint where the tendon is being tested. The nurse should use the flat, not pointed, end of the reflex hammer when striking the Achilles tendon. (The po inted end is used to strike over small areas, such as the thumb placed over the biceps tendon.) Tapping the tendon slowly and softly wouldn’t provoke a deep tendon reflex response. The nurse should hold the reflex hammer loosely, not tightly, between the thumb and fingers so it can swing in an arc. 8. A female client is admitted in a disoriented and restless state after sustaining a concussion during a car accident. Which nursing diagnosis takes highest priority in this client’s plan of care? a. Disturbed sensory perception (visual) b. Self-care deficient: Dressing/grooming c. Impaired verbal communication d. Risk for injury 8. Answer D. Because the client is disoriented di soriented and restless, the most important nursing diagnosis is risk for injury. Although the other options may be appropriate, they’re secondary because they don’t immediately affect the client’s health or safety. 9. A female client with amyotrophic lateral sclerosis (ALS) tells the nurse, “Sometimes I feel so frustrated. I can’t do anything without help!” This comment best supports which nursing diagnosis? a. Anxiety b. Powerlessness c. Ineffective denial d. Risk for disuse syndrome 9. Answer B. This comment best supports a nursing diagnosis of Powerlessness because ALS may lead to locked-in syndrome, characterized by an active and functioning mind locked in a body that can’t perform even simple daily tasks. Although Anxiety and Risk for disuse syndrome may be diagnoses associated with ALS, the client’s comment specifically refers to an inability to act autonomously. A diagnosis of Ineffective denial would be indicated if the client didn’t seem to perceive the personal relevance of symptoms or danger. 10. For a male client with suspected increased intracranial pressure (ICP), a most appropriate respiratory goal is to: a. prevent respiratory alkalosis. b. lower arterial pH. c. promote carbon dioxide elimination. d. maintain partial pressure of arterial oxygen (PaO2) above 80 mm Hg 10. Answer C. The goal of treatment is to prevent acidemia by eliminating carbon dioxide. That is because an acid environment in the brain causes cerebral vessels to dilate and therefore increases ICP. Preventing respiratory alkalosis and lowering arterial pH may bring about acidosis, an
Page 2 of 7
undesirable condition in this case. It isn’t necessary to maintain a PaO2 as high as 80 mm Hg; 60 mm Hg will adequately oxygenate most clients. 11. Nurse Maureen witnesses a neighbor’s husband sustain a fall from the roof of his house. The nurse rushes to the victim and determines the need to opens the airway in this victim by using which method? a. Flexed position b. Head tilt-chin lift c. Jaw thrust maneuver d. Modified head tilt-chin lift 11. Answer C. If a neck injury is suspected, the jaw thrust maneuver is used to open the airway. The head tilt–chin lift maneuver produces hyperextension of the neck and could cause complications if a neck injury is present. A flexed position is an inappropriate position for opening the airway. 12. The nurse is assessing the motor function of an unconscious male client. The nurse would plan to use which plan to use which of the following to test the client’s peripheral response to pain? a. Sternal rub b. Nail bed pressure c. Pressure on the orbital rim d. Squeezing of the sternocleidomastoid muscle 12. Answer B. Motor testing in the unconscious client can be done only by testing response to painful stimuli. Nail bed pressure tests a basic peripheral response. Cerebral responses to pain are tested using sternal rub, placing upward pressure on the orbital rim, or squeezing the clavicle or or sternocleidomastoid muscle. 13. A female client admitted to the hospital with a neurological problem asks the nurse whether magnetic resonance imaging may be done. The nurse interprets that the client may be ineligible for fo r this diagnostic procedure based on the client’s history of: a. Hypertension b. Heart failure d. Chronic obstructive pulmonary disorder c. Prosthetic valve replacement 13. Answer C. The client having a magnetic resonance imaging scan has all metallic objects removed because of the magnetic field generated by the device. A careful history is obtained to determine whether any metal objects are inside the client, such as orthopedic hardware, pacemakers, artificial heart valves, aneurysm clips, or intrauterine devices. These may heat up, become dislodged, or malfunction during this procedure. The client may be ineligible if significant risk exists. 14. A male client is having a lumbar puncture performed. The nurse would plan to place the client in which position? a. Side-lying, with a pillow under the hip b. Prone, with a pillow under the abdomen c. Prone, in slight-Trendelenburg’s position d. Side-lying, with the legs pulled up and head bent down onto chest. 14. Answer D. The client undergoing lumbar puncture is positioned lying on the side, with the legs pulled up to the abdomen and the head bent down onto the chest. This position helps open the spaces between the vertebrae. 15. The nurse is positioning the female client with increased intracranial pressure. Which of the following positions would the nurse avoid? a. Head mildline b. Head turned to the side c. Neck in neutral position d. Head of bed elevated 30 to 45 degrees 15. Answer B. The head of the client with increased intracranial pressure should be positioned so the head is in a neutral midline position. The nurse should avoid flexing or extending the client’s neck or turning the head side to side. The head of the bed should be raised to 30 to 45 degrees. Use of proper positions promotes venous drainage from the cranium to t o keep intracranial pressure down. 16. A female client has clear fluid leaking from the nose following a basilar skull fracture. The nurse assesses that this is cerebrospinal fluid if the fluid: a. Is clear and tests negative for glucose b. Is grossly bloody in appearance and has a pH of 6 c. Clumps together on the dressing and has a pH of 7 d. Separates into concentric rings and test positive of glucose
Page 3 of 7
16. Answer D. Leakage of cerebrospinal fluid (CSF) from the t he ears or nose may accompany basilar skull fracture. CSF can be distinguished from fro m other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material, called a halo sign. The fluid also tests positive for glucose. 17. A male client with a spinal cord injury is prone to experiencing automatic dysreflexia. The nurse would avoid which of the following measures to minimize the risk of recurrence? a. Stri Strict ct adhe adhere renc nce e to to a bowe bowell ret retra rain inin ing g pro progr gram am b. Keep Keepin ing g the the line linen n wri wrink nkle le-f -fre ree e und under er the the client d. Limiting bladder catheterization to c. Preventing unnecessary pressure on the lower limbs once every 12 hours 17. Answer D. The most frequent cause of autonomic dysreflexia is a distended bladder. Straight catheterization should be done every 4 to 6 hours, and foley catheters should be checked frequently to prevent kinks in the tubing. Constipation and fecal impaction are other causes, so maintaining bowel regularity is important. Other causes include stimulation of the skin from tactile, thermal, or painful stimuli. The nurse administers care to minimize risk in these areas. 18. The nurse is caring for the male client who begins to experience seizure activity while in bed. Which of the following actions by the nurse would be contraindicated? a. Loosening restrictive clothing b. Restraining the client’s limbs c. Removing the pillow and raising padded side rails d. Positioning the client to side, if possible, with the head flexed forward 18. Answer B. Nursing actions during a seizure include providing for f or privacy, loosening restrictive clothing, removing the pillow and raising side rails in the bed, and placing the client on one side with the head flexed forward, if possible, to allow the tongue to fall forward and facilitate drainage. The limbs are never restrained because the strong muscle contractions could cause the client harm. If the client is not in bed when seizure activity begins, the nurse lowers the client to the floor, if possible, protects the head from injury, and moves furniture that may injure the client. Other aspects of care are as described for the client who is in bed. 19. The nurse is assigned to care for a female client with complete right-sided hemiparesis. The nurse plans care knowing that this condition: a. The client has complete bilateral paralysis of the arms and legs. b. The client has weakness on the right side of the body, including the face and tongue. c. The client has lost the ability to move the right arm but is able to walk independently. d. The client has lost the ability to move the right arm but is able to walk independently. 19. Answer B. Hemiparesis is a weakness of one side of the body that may occur after a stroke. Complete hemiparesis is weakness of the face and tongue, arm, and leg on one side. Complete bilateral paralysis does not occur in this t his condition. The client with right-sided hemiparesis has weakness of the right arm and leg and needs assistance with feeding, bathing, and ambulating. 20. The client with a brain attack (stroke) has residual dysphagia. When a diet order is initiated, the nurse avoids doing which of the following? a. Giving the client thin liquids b. Thickening liquids to the consistency of oatmeal c. Placing food on the unaffected side of the mouth d. Allowing plenty of time for chewing and swallowing 20. Answer A. Before the client with dysphagia is started on a diet, the gag and swallow reflexes must have returned. The client is assisted with meals as needed and is given ample time ti me to chew and swallow. Food is placed on the unaffected side of the mouth. Liquids are thickened to avoid aspiration. 21. The nurse is assessing the adaptation of the female client to changes in functional status after a brain attack (stroke). The nurse assesses that the client is adapting most successfully if the client: a. Gets angry with family if they interrupt a task b. Experiences bouts of depression and irritability c. Has difficulty with using modified feeding utensils d. Consistently uses adaptive equipment in dressing self
Page 4 of 7
21. Answer D. Clients are evaluated as coping successfully with lifestyle changes after a brain attack (stroke) if they make appropriate lifestyle alterations, al terations, use the assistance of others, and have appropriate social interactions. Options A, B, and C are not adaptive behaviors. 22. Nurse Kristine is trying to communicate with a client with brain attack (stroke) and aphasia. Which of the following actions by the nurse would be least helpful to the client? a. Speaking to the client at a slower rate b. Allowing plenty of time for the client to respond c. Completing the sentences that the client cannot finish d. Looking directly at the client during attempts at speech 22. Answer C. Clients with aphasia after brain attack (stroke) ( stroke) often fatigue easily and have a short attention span. General guidelines when trying to communicate with t he aphasic client include speaking more slowly and allowing adequate response time, listening to and watching attempts to communicate, and trying to put the t he client at ease with a caring and understanding manner. The nurse would avoid shouting (because the client is not deaf), appearing rushed for a response, and letting family members provide all the responses for the t he client. 23. A female client has experienced an episode of myasthenic crisis. The nurse would assess whether the client has precipitating factors such as: a. Getting too little exercise b. Taking excess medication c. Omitting doses of medication d. Increasing intake of fatty foods 23. Answer C. Myasthenic crisis often is caused by undermedication and responds to the administration of cholinergic medications, such as neostigmine (Prostigmin) and pyridostigmine (Mestinon). Cholinergic crisis (the opposite problem) is i s caused by excess medication and responds to withholding of medications. Too little exercise and fatty food intake are incorrect. Overexertion and overeating possibly could trigger myasthenic crisis. 24. The nurse is teaching t eaching the female client with myasthenia gravis about the prevention of myasthenic and cholinergic crises. The nurse tells the client that this is most effectively done by: a. Eating large, well-balanced meals b. Doing muscle-strengthening exercises c. Doing all chores early in the day while less fatigued d. Taking medications on time to maintain therapeutic blood levels 24. Answer D. Clients with myasthenia gravis are taught to space out activities over the day to conserve energy and restore muscle strength. Taking medications correctly to maintain b lood levels that are not too low or too high is important. Muscle-strengthening exercises are not helpful and can fatigue the client. Overeating is a cause of o f exacerbation of symptoms, as is exposure to heat, crowds, erratic sleep habits, and emotional stress. 25. A male client with Bell’s palsy asks the nurse what has caused this thi s problem. The nurse’s response is based on an understanding that the cause is: a. Unknown, but possibly includes ischemia, viral infection, or an autoimmune problem b. Unknown, but possibly includes inc ludes long-term tissue malnutrition and cellular hypoxia c. Primary genetic in origin, triggered trig gered by exposure to meningitis d. Primarily genetic in origin, triggered by exposure to neurotoxins 25. Answer A. Bell’s palsy is a one-sided facial paralysis from compression of the facial nerve. The exact cause is unknown, but may include vascular ischemia, infection, exposure to viruses such as herpes zoster or herpes simplex, autoimmune disease, or a combination o f these factors. 26. The nurse has given the male client with Bell’s palsy instructions on preserving muscle tone in the face and preventing denervation. The nurse determines that the c lient needs additional information if the client states that he or she will: a. Exposure to cold and drafts b. Massage the face with a gentle g entle upward motion c. Perform facial exercises d. Wrinkle the forehead, blow out the cheeks, and whistle
Page 5 of 7
26. Answer A. Prevention of muscle atrophy with Bell’s palsy pal sy is accomplished with facial massage, facial exercises, and electrical stimulation of the nerves. Exposure to cold or drafts is avoided. Local application of heat to the face may improve blood flow and provide comfort. 27. Female client is admitted to the hospital with a diagnosis diag nosis of Guillain-Barre syndrome. The nurse inquires during the nursing admission interview if the client has history of: a. Seizures or trauma to the brain b. Meningitis during the last 5 years c. Back injury or trauma to the spinal cord d. Respiratory or gastrointestinal infection during the previous month. 27. Answer D. Guillain-Barré syndrome is a clinical syndrome of unknown origin that involves cranial and peripheral nerves. Many clients report a history of respiratory or gastrointestinal infection in the t he 1 to 4 weeks before the onset of neurological deficits. Occasionally, the syndrome can be triggered by vaccination or surgery 28. A female client with Guillian-Barre syndrome has ascending paralysis and is intubated and receiving mechanical ventilation. Which of the following strategies would the nurse incorporate in the plan of care to help the client cope with this illness? a. Giving client full control over care decisions and restricting visitors b. Providing positive feedback and encouraging active range of motion c. Providing information, giving positive feedback, and encouraging relaxation d. Providing intravaneously administered sedatives, reducing distractions and limiting visitors 28. Answer C. The client with Guillain-Barré syndrome experiences fear and anxiety from t he ascending paralysis and sudden onset of the disorder. d isorder. The nurse can alleviate these fears by providing accurate information about the client’s condition, giving expert care and positive feedback to the client, and encouraging relaxation and distraction. The family can become involved with selected care activities and provide diversion for the client as well.

29. A male client has an impairment of cranial nerve II. Specific to this impairment, the nurse would plan to do which of the following to ensure client to ensure client safety? a. Speak loudly to the client b. Test the temperature of the shower water c. Check the temperature of the food on the delivery tray. d. Provide a clear path for ambulation without obstacles 29. Answer D. Cranial nerve II is the optic o ptic nerve, which governs vision. The nurse can provide safety for the visually impaired client by clearing the path of obstacles o bstacles when ambulating. Testing the shower water temperature would be useful if there were an impairment of peripheral nerves. Speaking loudly may help overcome a deficit of cranial nerve VIII (vestibulocochlear). Cranial nerve VII (facial) and IX (glossopharyngeal) control taste from the anterior two thirds and posterior third of the tongue, respectively. 30. A female client has a neurological deficit involving the limbic system. Specific to this type of deficit, the nurse would document which of the following information related to the client’s behavior. a. Is disoriented to person, place, and time b. Affect is flat, with periods of emotional lability c. Cannot recall what was eaten for breakfast today d. Demonstrate inability to add and subtract; does not know who is president 30. Answer B. The limbic system is responsible for feelings (affect) and emotions. Calculation ability and knowledge of current events relates to function of the frontal lobe. The cerebral hemispheres, with specific regional functions, control orientation. Recall of recent events is controlled by the hippocampus.
