Question 1 of 5
A 25-year-old male comes to the emergency department with crushing, substernal chest pain. The pain radiates up to his jaw and down to his right arm. He has never had chest pain like this before. An ECG shows ST elevations in leads I, II, and AVF. A detailed history reveals that he had used cocaine 2 h prior to the onset of chest pain. Which of the following medications is contraindicated in the treatment of myocardial infarction caused by his cocaine use?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The nurse manages care for several clients receiving hormone replacement therapy (HRT). What will the priority assessment by the nurse include as related to side effects?
Correct Answer: A
Rationale: HRT, often involving estrogen, increases thrombophlebitis risk due to enhanced clotting factors. Calf pain signals possible deep vein thrombosis (DVT), a life-threatening side effect requiring immediate assessment, as it could lead to pulmonary embolism. Decreased libido , low-back pain , and fatigue may occur with HRT but are less urgent and not specific to its most dangerous complications. The nurse prioritizes calf pain due to its association with thromboembolism, a well-documented HRT risk, especially in smokers or those with vascular issues, making choice A the critical focus for safety.
Question 3 of 5
The patient has a potassium level of 5.9 mEq/L. The nurse is administering glucose and insulin. The patient's wife says, 'He doesn't have diabetes, why is he getting insulin?' What is the best response by the nurse?
Correct Answer: A
Rationale: In hyperkalemia (5.9 mEq/L), insulin shifts potassium into cells , lowering serum levels temporarily, paired with glucose to avoid hypoglycemia. Choice B misstates excretion. Choice C compares unnecessarily. Choice D attributes renal action incorrectly. A explains the mechanism accurately, making it the best response.
Question 4 of 5
A client with gout is prescribed allopurinol (Zyloprim). Which laboratory value should the nurse monitor?
Correct Answer: A
Rationale: Allopurinol reduces uric acid production, treating gout by inhibiting xanthine oxidase. Monitoring serum uric acid tracks efficacy, ensuring levels drop (normal: 3.5-7.2 mg/dL) to prevent flares. BUN reflects kidney function, relevant but secondary unless damage exists. White blood cells and platelets aren't directly affected unless hypersensitivity occurs (rare). Uric acid is the therapeutic target, aligning with allopurinol's mechanism, critical in gout where hyperuricemia drives symptoms. Regular checks confirm treatment success, guiding dose adjustments, making A the key value to monitor.
