In what area is an "ophthalmic use only" medication administered?

Choice A reason: Skipping tube placement risks misdelivery; full protocol ensures safety. Residual check alone isn’t enough, per nursing standards. This misses a critical step, universally distinct as incomplete for safe tube administration.

Choice B reason: No placement verification risks errors; drugs need flushing between. This lacks a key safety check, per nursing pharmacology. It’s universally insufficient, distinctly omitting tube confirmation for effective delivery.

Choice C reason: Missing placement and residual checks, plus no flush between drugs, risks errors. Full protocol is safer, per nursing standards. This shortcut fails universally, distinctly compromising medication administration accuracy.

Choice D reason: Checking placement, residual, and flushing between digoxin and propranolol ensures safety and efficacy. This full process aligns with nursing tube administration standards, universally recognized and distinctly applied for best outcomes.

Choice A reason: Insulin, a protein, is broken down in the stomach; parenteral delivery preserves it. This fits, per nursing pharmacology. It’s universally true, distinctly ensuring effective diabetes management.

Choice B reason: Insulin doesn’t affect bile production; stomach destruction is the issue. This misaligns, per nursing standards. It’s universally distinct, errors in insulin’s purpose.

Choice C reason: Solvent composition isn’t why; gastric digestion prevents oral use. This errors, per nursing pharmacology. It’s universally distinct, missing the destruction rationale.

Choice D reason: Pepsin secretion isn’t relevant; stomach acid destroys insulin. This misidentifies, per nursing standards. It’s universally distinct, unrelated to parenteral necessity.
