IGGY Chapter 41 Critical Care of Patients with Neurologic Emergencies Study Questions with Answers A client is in the emergency department reporting a brief episode during which he was dizzy, unable to speak, and felt numbness in his left leg. Currently the client's neurologic examination is normal. About what drug would the nurse plan to teach the patient? a. Alteplase b. Clopidogrel c. Heparin sodium d. Mannitol - Correct Answer ANS: B This client's signs and symptoms are consistent with a transient ischemic attack, and the client would likely be prescribed aspirin or clopidogrel to prevent platelet aggregation on discharge. Alteplase is used for ischemic stroke. Heparin and mannitol are not used for this condition. The nurse is preparing a client for discharge from the emergency department after experiencing a transient ischemic attack (TIA). Before discharge, which factor would the nurse identify as placing the client at high risk for a stroke? a. Age greater than or equal to 75 b. Blood pressure greater than or equal to 160/95 c. Unilateral weakness during a TIA d. TIA symptoms lasting less than a minute - Correct Answer ANS: C The client who has a TIA is at risk for a stroke is he or she has one-sided (unilateral) weakness during a TIA. Risk factors also include an age greater than or equal to 60, blood pressure greater than or equal to 140/90 (either or both systolic and diastolic), and/or a long duration of TIA symptoms. One minute is not a very long time for symptoms to occur. The nurse is taking a history from a daughter about her father's onset of stroke signs and symptoms. Which statement by the daughter indicates that the client likely had an embolic stroke? a. Client's symptoms occurred slowly over several hours. b. Client because increasingly lethargic and drowsy. c. Client reported severe headache before other symptoms. d. Client has a long history of atrial fibrillation. - Correct Answer ANS: D The major cause of embolic strokes is a history of heart disease, especially atrial fibrillation. Most clients who have an embolic stroke have acute sudden neurologic symptoms but stay alert rather than lethargic. Decreasing level of consciousness and severe headache are more common in clients who have hemorrhagic strokes.
