Which drug is most likely to be ordered for the client with herpes simplex virus?

Correct Answer: A

Rationale: Herpes simplex virus (HSV) is a viral infection requiring antiviral therapy, and acyclovir (Zovirax) is the gold-standard treatment due to its specific action against herpesviruses. It inhibits viral DNA replication, reducing symptom duration and severity, making it the most likely choice (A). Zidovudine targets HIV, a retrovirus, not HSV, and is irrelevant here. Nystatin is an antifungal, ineffective against viruses. Metronidazole treats bacterial and protozoal infections, not viral ones. Acyclovir's specificity and efficacy for HSV, supported by clinical guidelines, make it the priority drug. The nurse must recognize this distinction to ensure appropriate therapy, as misidentification could delay recovery or worsen outcomes. Choice A stands out as the only antiviral tailored to HSV's pathophysiology, ensuring targeted treatment.

Correct Answer: A

Rationale: Furosemide is a loop diuretic commonly used to treat conditions involving edema such as heart failure, liver disease, and kidney disorders. By promoting diuresis (increased urine production), furosemide helps the body eliminate excess fluid, leading to a decrease in edema or swelling. Therefore, a patient given furosemide for diuresis should experience a decrease in edema as the drug acts on the kidneys to increase urine output and eliminate extra fluids from the body.

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: The unlabeled use for a medication refers to a use that is not approved by regulatory agencies but has shown effectiveness in clinical practice. In this case, the unlabeled use for a medication might be to treat PTSD (Post-Traumatic Stress Disorder). While the medication may not be specifically indicated for this condition, it may have shown benefits in managing the symptoms of PTSD based on clinical experience or research studies. It is important to note that using a medication for an unlabeled use should always be done under the supervision of a healthcare professional.
