A medicine cup is inaccurate for medication doses less than:

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.

Choice A reason: Rectal is enteral, using the GI tract for absorption. Vaginal isn’t enteral. This fits nursing pharmacology standards. It’s universally distinct, part of digestive routes.

Choice B reason: Nasogastric delivers to stomach, an enteral method clearly. Vaginal differs entirely. This aligns with nursing standards. It’s universally distinct, a GI route.

Choice C reason: Vaginal is topical/mucosal, not enteral like GI routes. This is the exception per nursing pharmacology. It’s universally distinct, outside digestive administration methods.

Choice D reason: Oral is enteral, absorbed via digestive system typically. Vaginal isn’t included. This matches nursing standards. It’s universally distinct, a core enteral route.
