With regard to non-depolarising neuromuscular blocking drugs:

Correct Answer: A

Rationale: Pancuronium is primarily renally eliminated, a true statement, prolonged in kidney failure. Rocuronium, a steroidal agent, not isoquinolone (like atracurium), is false. Rocuronium is hepatically metabolized, not via Hofmann elimination (atracurium does), so that's false. Vecuronium is mostly biliary excreted, not renal, making that false. Atracurium uses plasma esterases and Hofmann elimination, not pseudocholinesterases alone. Pancuronium's renal clearance is critical for surgical planning, especially in renal patients.

Correct Answer: A

Rationale: Superinfections are secondary infections that occur as a result of disrupting the normal balance of microorganisms in the body, often due to prolonged or broad-spectrum antibiotic use. They can involve the emergence of resistant strains or the overgrowth of opportunistic pathogens. Therefore, superinfections are more likely to occur with prolonged antibiotic use or broad-spectrum antibiotics that disrupt the normal flora of the body. It is less common for superinfections to occur with narrow spectrum antibiotics, as they target a more limited range of bacteria and are less likely to disrupt the overall microbial balance in the body.

Correct Answer: C

Rationale: When a client is undergoing chemotherapy, the priority nursing diagnosis would be related to potential complications from the treatment. Decreased cardiac output is a critical concern because certain chemotherapy drugs can have cardiotoxic effects, leading to reduced heart function. Monitoring and addressing any changes in cardiac output are vital for the overall well-being of the client during chemotherapy. While the other options may also be relevant, such as managing fear, anxiety, and altered nutrition, decreased cardiac output takes precedence due to its immediate impact on the client's cardiovascular health.

Correct Answer: A

Rationale: Diphenhydramine's anticholinergic effects (dryness) are tolerable given 75% rhinitis improvement. Continue at current dose . Discontinuing loses benefit. Adding chlorpheniramine increases side effects. Surgery (D, E) is excessive. Balancing efficacy and mild side effects favors continuation.
