Which of the following is a drug that produces vasodilation, improves cardiac output, and lowers blood pressure?

Choice A reason: Smoking impacts liver, not kidney excretion speed primarily. Liver metabolism accelerates instead. This choice errors per nursing pharmacology. It’s universally distinct, targeting the wrong organ for effect.

Choice B reason: Smoking induces liver enzymes, speeding drug metabolism significantly. This aligns with nursing pharmacology standards. It’s universally recognized, distinctly affecting drug efficacy and dosing needs.

Choice C reason: Smoking hastens, not slows, liver drug metabolism typically. This choice reverses nursing pharmacology facts. It’s universally distinct, contradicting known metabolic effects of smoking.

Choice D reason: Kidney excretion isn’t slowed by smoking; liver speeds metabolism. This choice misaligns with nursing standards. It’s universally distinct, errors in organ and effect direction.

Choice A reason: Lasix is given IV or orally, not subQ in the belly. Heparin fits this route, per nursing standards. This errors universally, distinctly missing subcutaneous administration.

Choice B reason: Digoxin is oral or IV, not subQ in the abdomen. Heparin is correct, per nursing pharmacology. This misaligns universally, distinctly unrelated to belly injections.

Choice C reason: Heparin is injected subQ in the belly, 2 inches from umbilicus, for anticoagulation. This matches, per nursing standards. It’s universally applied, distinctly effective.

Choice D reason: Phenobarbital is oral or IV, not subQ in the belly. Heparin suits this, per nursing pharmacology. This errors universally, distinctly off-target for route.
