Insulin is a medication that is given parenterally because:
It is destroyed in the stomach
It causes an increase in bile secreted by the gall bladder
It is made up of a drug dissolved in alcohol and water
It decreases the secretion of pepsin
The Correct Answer is A
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.

Explanation
Choice A reason: 30 cc overestimates; cups lose accuracy below 10 cc typically. Syringes are better for small doses. This errors per nursing standards. It’s universally distinct, impractical for precise small-volume measurement.
Choice B reason: 10 cc is the threshold; below this, cups are inaccurate. Syringes ensure precision, per nursing pharmacology. This aligns universally, distinctly standard for accurate liquid dosing.
Choice C reason: 20 cc exceeds the inaccuracy limit; 10 cc is correct. Cups falter below this level. This choice errors per nursing standards. It’s universally distinct, overestimating the threshold.
Choice D reason: 5 cc underestimates; inaccuracy starts at 10 cc for cups. Syringes are needed below this. This errors per nursing pharmacology. It’s universally distinct, missing the mark.
Correct Answer is B
Explanation
Choice A reason: Anti-manics, like lithium, treat mania; tricyclics target depression. This misidentifies, per nursing pharmacology. It’s universally distinct, errors in mood disorder classification.
Choice B reason: Tricyclics, like amitriptyline, are antidepressants, lifting mood effectively. This fits, per nursing standards. It’s universally recognized, distinctly applied for depression management in practice.
Choice C reason: Antipsychotics treat psychosis; tricyclics address depression, not hallucinations. This errors, per nursing pharmacology. It’s universally distinct, missing the antidepressant focus.
Choice D reason: Anti-anxiety drugs calm; tricyclics treat depression, not just anxiety. This misaligns, per nursing standards. It’s universally distinct, errors in drug purpose.
