Question 1 of 5
The primary function of luteinizing hormone (LH) in men is to
Correct Answer: D
Rationale: Luteinizing hormone (LH), from the pituitary, stimulates Leydig cells in the testes to produce testosterone, the primary male sex hormone, making its regulation LH's chief role in men. Sperm production is driven by follicle-stimulating hormone (FSH), not LH, though both support fertility. Secondary sex characteristics, like body hair, depend on testosterone, which LH indirectly influences by controlling its synthesis, not directly regulating the traits. Growth of male sex organs relies on androgens, again tied to testosterone, not LH's direct action. Testosterone regulation is LH's specific function, as it triggers the steroidogenesis pathway, critical for male physiology, distinguishing it from FSH's gamete focus and underscoring its hormonal primacy in this context.
Question 2 of 5
Which method would the nurse use to administer medications to school-age children?
Correct Answer: B
Rationale: School-age kids (6-12) grasp brief explanations-e.g., 'This helps your cough'-fitting their cognitive level, easing administration. Full decision-making exceeds maturity. Holding down distresses, not needed. Lengthy talks lose attention. Brief explanation leverages development, ensuring cooperation.
Question 3 of 5
The client receives hydroxychloroquine sulfate (Plaquenil). Which test does the nurse tell the client should be done on a regular basis?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A 63-year-old woman with a history of cardiac arrhythmia maintained on quinidine presents to her primary care physician complaining of frequency, urgency, and dysuria. Urine culture reveals >100,000 CFU/mL of Escherichia coli. She is given a prescription for ciprofloxacin 500 mg to be taken twice daily for 7 days. Which of the following sequelae could be problematic for this patient?
Correct Answer: D
Rationale: Quinidine and ciprofloxacin both prolong the QT interval, risking torsades de pointes. Option , QT prolongation, is correct-combined use heightens arrhythmia risk in this patient. Asystole , MI , pulmonary edema , and embolism (E) aren't directly linked. This drug interaction demands monitoring, critical given her cardiac history.
Question 5 of 5
A 45-year-old woman undergoes a complete hysterectomy for leiomyomas and dysfunctional uterine bleeding. The surgeon wants to prescribe a pain relief medication following the procedure, but the patient's serum creatinine is 1.2 mg/dL. Which of the following pain relief medications should the surgeon avoid prescribing?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
