Correct Answer: D

Rationale: The correct adverse effect to monitor for when administering subcutaneous epinephrine for anaphylaxis is tachycardia. Epinephrine stimulates adrenergic receptors, leading to an increased heart rate (tachycardia). Hypotension (Choice A) is less likely due to the vasoconstrictive effects of epinephrine. Hyperthermia (Choice B) and hypoglycemia (Choice C) are not commonly associated with epinephrine administration for anaphylaxis.

Correct Answer: A

Rationale: Heparin is best absorbed and less likely to cause hematomas when administered into subcutaneous tissue, specifically the abdomen, which is a common site for subcutaneous injections. Injecting heparin into a muscle (Choice B) is incorrect as it should be administered subcutaneously. Massaging the site after administering the medication (Choice C) is contraindicated as it can cause tissue damage or bruising. Using a 22-gauge needle (Choice D) is not recommended for subcutaneous injections of heparin; a smaller needle size such as 25-26 gauge is preferred for subcutaneous administration.

Correct Answer: B

Rationale: The correct answer is B: Proteinuria. Proteinuria can indicate nephrotoxicity, a known adverse effect of gentamicin. Gentamicin is known to cause kidney damage, leading to proteinuria. Hypoglycemia is not typically associated with gentamicin use but may be related to insulin administration or other medical conditions. Nasal congestion is not a common adverse effect of gentamicin. Visual disturbances are also not typically reported with gentamicin use.
