Extract:
Question 1 of 5
A client develops a temperature of 102°F following coronary artery bypass surgery. The nurse should notify the physician immediately because elevations in temperature:
Correct Answer: C
Rationale: Fever post-CABG increases metabolic demand, potentially decreasing cardiac output in a compromised heart, requiring immediate attention. Tamponade and rejection have other signs.
Question 2 of 5
The most important reason to closely assess circumferential burns at least every hour is that they may result in:
Correct Answer: D
Rationale: Full-thickness circumferential burns are nonelastic and create an internal tourniquet effect, compromising distal blood flow in extremities or respiratory motion in the torso, leading to loss of peripheral pulses.
Question 3 of 5
A 40-year-old client is admitted to the coronary care unit with chest pain and shortness of breath. The physician diagnosed an anterior wall myocardial infarction. What tests should the nurse anticipate?
Correct Answer: D
Rationale: Lactic dehydrogenase and CPK are enzymes released from injured myocardial tissue.
Question 4 of 5
A client with Addison's disease has been receiving glucocorticoid therapy. Which finding indicates a need for dosage adjustment?
Correct Answer: C
Rationale: Rapid weight gain (6 pounds in a week) suggests fluid retention, a sign of glucocorticoid excess, requiring dosage adjustment. Dizziness may indicate underdosing, and the other symptoms are less specific.
Question 5 of 5
The doctor has prescribed aspirin 325 mg daily for a client with transient ischemic attacks. The nurse explains that aspirin was prescribed to:
Correct Answer: D
