Correct Answer: C

Rationale: Zanamivir is an antiviral medication used to treat influenza, not herpes simplex virus or hepatitis B. Varicella-zoster virus is the cause of chickenpox and shingles, which are treated with other antivirals like acyclovir. This question seems to have an error, as zanamivir is not used for any of the listed conditions.

Correct Answer: A

Rationale: The therapeutic and adverse effects associated with these drugs are related to their adrenergic-receptor-site specificity; that is, the ability to react with specific adrenergic receptor sites without activating them, thus preventing the typical manifestations of sympathetic nervous system (SNS) activation. By occupying the adrenergic receptor site, they prevent norepinephrine released from the nerve terminal or from the adrenal medulla from activating the receptor, thus blocking the SNS effects. The nurse should understand the mechanism of action of adrenergic blocking agents to ensure safe and effective administration.

Correct Answer: D

Rationale: Drowsiness is a common side effect of oxycodone, an opioid analgesic. Patients should be advised to avoid activities requiring alertness, such as driving, while taking this medication. Paresthesia (A), increased intracranial pressure (B), and occipital headache (C) are not typical side effects of oxycodone.
