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

Answer and Explanation

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.

Correct Answer is C

Explanation

Choice A reason: Vasodilators widen blood vessels, not airways, unlike albuterol’s action. Bronchodilators target lungs, per nursing pharmacology. This misidentifies the drug class, a distinct error universally understood as unrelated to airway dilation in respiratory care.

Choice B reason: Salicylates, like aspirin, reduce pain or inflammation, not dilate airways. Bronchodilators fit albuterol’s role, per nursing standards. This errors in classification, universally distinct from respiratory drugs, missing the mark comprehensively.

Choice C reason: Bronchodilators, like albuterol, relax and dilate airways, improving breathing. This matches their purpose, aligning with nursing pharmacology. It’s a universal term, distinctly applied to drugs treating asthma or COPD effectively in practice.

Choice D reason: Expectorants loosen mucus, not dilate airways like bronchodilators do. Albuterol’s action differs, per nursing standards. This misaligns with the question’s focus, a distinct universal error in pharmacology classification for airway management.

A. Provide a bolus of medication to the patient at one time B. Can be crushed, chewed or the contents placed in food C. Are also called pills D. Reduce the number of doses given each day

Correct Answer is D

Explanation

Choice A reason: Bolus is instant; time-release spreads meds slowly instead. Reduced doses fit better. This errors per nursing pharmacology. It’s universally distinct, incorrect.

Choice B reason: Crushing ruins time-release; reduced dosing is the goal. This choice misaligns with nursing standards. It’s universally distinct, errors in handling.

Choice C reason: Pills aren’t specific to time-release; dose reduction is key. This errors per nursing pharmacology. It’s universally distinct, lacks precision.

Choice D reason: Time-release capsules extend action, cutting daily doses effectively. This aligns with nursing pharmacology standards. It’s universally distinct, reducing frequency.
