Critical Care of Patients With Acute Coronary Syndromes

1. A client is receiving an infusion of tissue plasminogen activator (tPA). The nurse assesses the client to be disoriented to person, place, and time. What action by the nurse is best? a. Assess the client’s pupillary responses. b. Request a neurologic consultation. c. Call the primary health care provider immediately. d. Take and document a full set of vital signs. ANS: C A change in neurologic status in a client receiving t-PA could indicate intracranial hemorrhage. The nurse would notify the primary health care provider immediately. A full assessment, including pupillary responses and vital signs, occurs next. The nurse may or may not need to call a neurologist.

A client received tissue plasminogen activator (tPA) after a myocardial infarction and now is on an intravenous infusion of heparin. The client’s spouse asks why the client needs this medication. What response by the nurse is best? a. “The t-PA didn’t dissolve the entire coronary clot.” b. “The heparin keeps that artery from getting blocked again.” c. “Heparin keeps the blood as thin as possible for a longer time.” d. “The heparin prevents a stroke from occurring as the t-PA wears off.” ANS: B After the original intracoronary clot has dissolved, large amounts of thrombin are released into the bloodstream, increasing the chance of the vessel reoccluding. The other statements are not accurate. Heparin is not a “blood thinner,” although laypeople may refer to it as such.

A client is in the hospital after suffering a myocardial infarction and has bathroom privileges. The nurse assists the client to the bathroom and notes the client’s O2 saturation to be 95%, pulse 88 beats/min, and respiratory rate 16 breaths/min after returning to bed. What action by the nurse is best? a. Administer oxygen at 2 L/min. b. Allow continued bathroom privileges. c. Obtain a bedside commode. d. Suggest the client use a bedpa
