Relaxation of bladder b. Decrease in peristalsis c. Dilation of bronchioles d. Decrease in heart rate to normal e. Increase in salivary gland secretion

ANS: A, B, C When the sympathetic nervous system is activated, the heart rate increases, vasodilation in skeletal muscles supplies them with more oxygen, the bronchioles dilate to take in more air, and the liver changes glycogen to glucose to provide energy. Relatively less important activities such as digestion (and salivation) are slowed, and vasoconstriction in the skin and viscera permits greater blood flow to more vital organs such as the brain, heart, and muscles. The bladder muscle relaxes, and the sphincter constricts to prevent urination.

Rising temperature c. Decreasing systolic pressure d. Dilated pupil on affected side e. Decreasing level of consciousness (LOC)

ANS: A, B, D, E Headache, increasing systolic pressure, decreasing LOC, dilated pupil on affected side, and rising temperature are all signs of increased ICP. C. Decreasing systolic blood pressure is not associated with increased intracranial pressure.

The nurse is caring for a patient scheduled for a computed tomography (CT) scan with contrast. What should be included in pre-procedure preparation? (Select all that apply.) a. Check blood urea nitrogen (BUN) and creatinine levels. b. Question the patient about allergies to dye, shellfish, or iodine. c. Determine if the patient has aneurysm clips or metal pins in the body. d. Explain to the patient that a sensation of warmth may be felt when dye is injected. e. Tell the patient to report any nausea, itchiness, or difficulty breathing during the scan.

ANS: A, B, D, E Patients who are receiving dye should be warned that they may feel a sensation of warmth following the injection; warmth in the groin area may make them feel as though they have been incontinent of urine. Nausea, diaphoresis, itching, or difficulty breathing may indicate allergy to the dye and should be reported immediately to the physician or nurse practitioner. Sedation may be required for patients who are agitated or disoriented. Patients who are in pain may require pain medication before the examination. The patient should be questioned about any allergies to contrast material, iodine, or shellfish. The BUN and creatinine levels should be checked before administration of contrast material because it is excreted through the kidneys. Patients with elevated BUN and creatinine or known renal disease may be unable to tolerate the contrast material. C. Clips or metal pins in the body would be assessed if the patient were scheduled for an MRI.

The nurse is planning to use the FOUR tool to assess a patients neurological functioning. In which areas should the nurse collect data when using this tool? (Select all that apply.) a. Reflexes b. Eye response c. Verbal response d. Motor movement e. Breathing pattern

The nurse is caring for a hospitalized patient who has had a stroke and is waiting to be transferred to a rehabilitation facility. What nursing action can best maximize the patients rehabilitation potential while awaiting the transfer? a.Teach the patient what to expect at the rehabilitation facility. b.Keep the patient on bedrest to conserve energy for rehabilitation. c.Call the physical therapist for bedside rehabilitation until the transfer. d.Turn the patient every 2 hours to prevent pressure ulcers and contractures.

ANS:C Rehabilitation should begin as soon as the patient is stable. Waiting until the patient is at the rehabilitation facility to begin therapy wastes valuable time. A. Teaching the patient what to expect at the rehabilitation facility will not maximize the patients rehabilitation potential. B. Keeping the patient on bedrest could cause further mobility issues. D. Turning the patient every 2 hours to prevent ulcer formation and contractures will not necessarily maximize the patients rehabilitation potential.

The patient is diagnosed with a cerebral vascular accident that has the slowest rate of recovery and the highest probability of causing extensive neurological deficits. For which type of stroke should the nurse plan care for this patient? a.Thrombotic stroke b.Cerebral aneurysm c.Subarachnoid hemorrhage (SAH) d.Reversible ischemic neurological deficit (RIND)

ANS:C SAH is caused by rupture of blood vessels on the surface of the brain. This type of infarct has the slowest rate of recovery and the highest probability of leaving the patient with extensive neurological deficits. B. Aneurysms are often asymptomatic if they do not bleed. D. RIND is reversible. A. A thrombotic stroke does not have the slowest rate of recovery.

The nurse is planning care for a client with right-sided weakness and aphasia from a transient ischemic attack (TIA). Which area of the brain should the nurse realize was affected in this client? a.Medulla b.Occipital lobe c.Left hemisphere d.Right hemisphere

ANS:C Symptom onset is sudden and generally involves one side of the bodythe side of the body opposite to the damaged area. A. B. The manifestations of right-sided weakness and aphasia would not be present if the TIA occurred in the medulla or occipital lobe. D. The client would have left-sided manifestations if the TIA occurred in the right hemisphere.

The nurse is reviewing teaching provided to a patient with transient ischemic attack (TIA). Which statement indicates that further teaching is required? a.The risk factors and symptoms of a TIA are just like those of a stroke. b.I need to stop smoking to help lower my chances of this happening again. c.My risk for Alzheimers disease is increased now, so Ill have to stop driving. d.I recognize how important it is to take my anti-hypertension medications regularly.

ANS:C There is no association between TIA and the development of Alzheimers disease. A. The risk factors, causes, and symptoms of a TIA are identical to a cerebrovascular accident (CVA). Patients who have had a TIA have an increased risk of having a stroke. Treatment, therefore, is mostly focused on minimizing the patients risk factors for a stroke. B. D. Modifiable risk factors are those risks that can be changed by treatment, such as treating high blood pressure, or by lifestyle modification, such as stopping smoking.

The nurse is involved in a blood pressure clinic in the community, and an individual with possible stroke symptoms is brought for evaluation. Which findings in the F.A.S.T. assessment indicate the need to call emergency personnel? (Select all that apply.) a.The patient sways when asked to stand still with eyes closed. b.The patient is unable to follow directions during the assessment. c.The patient is unable to repeat a stated phrase exactly as it was stated. d.The patients face shows signs of uneven symmetry when asked to smile. e.When asked to close the eyes and hold arms straight in front, one arm drifts downward.

ANS:C, D, E The acronym F.A.S.T. can help identify a stroke. Ask the person to smile: If the face droops or is uneven on one side, it is abnormal. Ask the person to close his or her eyes and hold arms out in front of him or her: If an arm cannot be raised or drifts downward, it is abnormal. Ask the person to say It is a bright and sunny day: Any difficulty understanding or speaking is abnormal. Call 911 immediately for any abnormal findings. A. These are all indicators of a possible stroke. Brain cells may be dying. B. Inability to follow instructions is a concern but is not part of the F.A.S.T. assessment.
