Question 1 of 5
A patient comes to the hospital with a suspected opioid overdose, what would be the appropriate medication to be administered?
Correct Answer: B
Rationale: Naloxone is the appropriate medication to be administered to a patient with a suspected opioid overdose. Naloxone is an opioid receptor antagonist, meaning it can quickly reverse the effects of opioids on the central nervous system. It works by binding to the same receptors in the brain that opioids target, blocking their effects and rapidly restoring normal respiration and consciousness in a person who has overdosed on opioids. This can be a life-saving treatment for opioid overdose patients. Exenatide, Heparin, and Tolvaptan are not appropriate medications for reversing opioid overdose.
Question 2 of 5
The following drugs undergo phase II metabolism by hepatic acetylation enzymes (N-acetyltransferases):
Correct Answer: D
Rationale: Isoniazid undergoes phase II acetylation via hepatic N-acetyltransferases, and the rate of metabolism can vary between slow and fast acetylators.

Question 4 of 5
The nurse is caring for a client receiving warfarin (Coumadin). Which instruction should the nurse include?
Correct Answer: A
Rationale: Warfarin's efficacy drops with high vitamin K intake, like spinach , risking clots'avoidance is key. Milk doesn't help. Stopping or doubling risks instability. Spinach avoidance aligns with warfarin's action, critical in anticoagulation where diet impacts INR, making A the essential instruction.
Question 5 of 5
Androgen is secreted by
Correct Answer: C
Rationale: Androgens, mainly testosterone, are secreted by the testes' Leydig cells, activated by pituitary LH, making the testes the source. FSH regulates sperm, not androgens. GnRH from the hypothalamus triggers LH/FSH release, indirectly affecting androgens. The pituitary releases LH/FSH, not androgens. The testes' direct secretion role is fundamental, driven by LH, distinguishing it from regulatory hormones.
