When categorizing medications, drug classifications may be defined by the effects of the drug and:

The symptoms the drug relieves.

The dosage amounts.

Patient tolerance.

The nursing implications.

Answer and Explanation

The Correct Answer is A

Choice A reason: Classifications like “analgesics” pair effects (pain relief) with symptoms (pain); this pharmacological basis groups drugs by therapeutic purpose and mechanism.

Choice B reason: Dosage varies within classes; it’s not a defining trait, as classifications focus on action (e.g., beta-blockers), not specific amounts administered.

Choice C reason: Tolerance is patient-specific, not a classification criterion; drugs are grouped by effect and symptom relief, not individual response variations.

Choice D reason: Nursing implications guide administration, not classification; categories stem from pharmacology (e.g., antihypertensives), not care protocols or implications.

Correct Answer is ["A"]

Explanation

Choice A reason: Multiple pharmacies increase polypharmacy risk; 16 prescriptions across four sources raise chances of duplication or interactions, lacking centralized oversight.

Choice B reason: Five hypertension drugs signal polypharmacy; excessive medications for one condition heighten interaction risks, potentially causing adverse effects or toxicity.

Choice C reason: Daughter’s help with eyedrops aids compliance; this single-task assistance doesn’t inherently increase drug numbers or polypharmacy-related risks.

Choice D reason: Weekly warfarin tests monitor safety; this manages one drug’s effect, not indicating polypharmacy, but rather appropriate therapeutic oversight.

Choice E reason: Allergies affect drug choice, not quantity; this doesn’t contribute to polypharmacy, as it’s a sensitivity issue, not a medication count concern.

A. 5 mL B. 7 mL C. 10 mL D. 14 mL

Correct Answer is B

Explanation

Choice A reason: 5 mL gives 125 mg; this underdoses the 175 mg order, reducing Ceclor’s antibacterial effect, risking persistent ear infection due to insufficient concentration.

Choice B reason: 7 mL is correct; 175 mg divided by 125 mg/5 mL equals 7 mL, delivering the exact cephalosporin dose for effective otitis media treatment.

Choice C reason: 10 mL provides 250 mg; this overdoses Ceclor, risking gastrointestinal upset or resistance, exceeding the therapeutic need for the infection safely.

Choice D reason: 14 mL yields 350 mg; this extreme overdose amplifies side effects like diarrhea or toxicity, far beyond the ordered 175 mg dose requirement.
