The nurse administering medications to a client is aware that the primary reason that most drugs are administered orally is because the oral route:

Is most reliable in terms of onset.

Is most convenient.

Is best tolerated by clients.

Ensures fast drug action.

Answer and Explanation

The Correct Answer is B

Choice A reason: While reliability exists, the oral route is less predictable than IV administration due to variability in absorption caused by digestive factors, making it less reliable for rapid or consistent onset.

Choice B reason: Convenience is the primary advantage of oral administration. It allows ease of self-administration, enabling clients to manage their medications without healthcare provider intervention, making it the most frequently used route.

Choice C reason: While many clients tolerate oral medications well, others may face challenges, such as difficulty swallowing or gastric irritation, meaning tolerability varies and is not a universal advantage of this route.

Choice D reason: The oral route does not ensure fast action due to time required for digestion, absorption, and metabolism, making it slower compared to routes like IV or sublingual administration.

Correct Answer is C

Explanation

Choice A reason: Convenience doesn’t ensure efficacy; supplements lack rigorous testing, potentially delivering inconsistent doses or contaminants, unlike prescription drugs’ controlled standards.

Choice B reason: Cost isn’t a clinical justification; lower price may reflect unregulated production, risking potency or safety compared to prescriptions validated by scientific trials.

Choice C reason: Supplements aren’t FDA-regulated like prescriptions; lacking standardized purity and efficacy tests, they may contain variable active ingredients, posing therapeutic risks.

Choice D reason: Plant-based doesn’t guarantee safety; many herbs are toxic or interact harmfully with drugs, unlike prescriptions with established pharmacokinetics and safety profiles.

A. 90-degree B. 45-degree C. 15-degree D. 25-degree

Correct Answer is A

Explanation

Choice A reason: IM injections use a 90-degree angle; this ensures deep muscle penetration for average-weight adults, optimizing drug absorption into vascular tissue.

Choice B reason: 45 degrees is for subcutaneous injections; it’s too shallow for IM, risking fat deposition instead of muscle, reducing efficacy in this context.

Choice C reason: 15 degrees is far too shallow; it’s not a standard angle, likely depositing drug in skin layers, failing to reach muscle for intended absorption.

Choice D reason: 25 degrees mimics subcutaneous; it doesn’t reach muscle depth, compromising IM delivery and therapeutic effect in an average-weight client.
