Dextromethorphan is an effective over-the-counter (OTC) option for the treatment of which of the following conditions/symptoms?
Coronavirus
Allergic rhinitis
Nonproductive cough
Ineffective productive cough
The Correct Answer is C
A. Coronavirus: Dextromethorphan does not treat viral infections such as coronavirus. While it may help manage a symptom like a cough, it has no antiviral properties or effect on the underlying infection.
B. Allergic rhinitis: Allergic rhinitis is primarily treated with antihistamines, intranasal corticosteroids, or decongestants. Dextromethorphan does not address nasal congestion, sneezing, or histamine-mediated symptoms.
C. Nonproductive cough: Dextromethorphan is an antitussive that suppresses the cough reflex, making it effective for dry, nonproductive coughs where coughing provides no benefit and causes discomfort or sleep disturbance.
D. Ineffective productive cough: In a productive cough, suppression with dextromethorphan is not recommended because coughing helps clear secretions from the airways. Using it in this situation could worsen airway obstruction or infection risk.

Correct Answer is B
Explanation
Behind-the-counter (BTC) medications do not require a prescription but must be dispensed by a pharmacist. These medications, such as pseudoephedrine, are kept behind the pharmacy counter to ensure safe use and to allow the pharmacist to provide counseling on proper dosing, contraindications, and potential side effects. BTC drugs are more restricted than over-the-counter medications due to safety concerns, potential for misuse, or interactions with other medications. The pharmacist acts as a gatekeeper to ensure appropriate use, but a formal prescription from a healthcare provider is not required for these medications.
Correct Answer is B
Explanation
A. Rest, Incubation, Circulation, Elevation: “Incubation” is not a recognized component of musculoskeletal injury care. Circulation is important physiologically but is not part of the standard R.I.C.E. protocol.
B. Rest, Ice, Compression, Elevation: R.I.C.E. is the acronym for acute musculoskeletal injury management. Rest minimizes further tissue damage, ice induces vasoconstriction to reduce swelling and pain, compression limits edema formation, and elevation uses gravity to facilitate venous and lymphatic return, decreasing inflammatory fluid accumulation in the injured area.
C. Rest, Incubation, Compression, Elevation: Again, “Incubation” is incorrect. The term does not relate to acute injury treatment or inflammation control.
D. Rest, Ice, Circulation, Exercise: While ice and rest are appropriate, “circulation” and early “exercise” are not initial acute interventions. Premature exercise may exacerbate tissue injury and bleeding, delaying healing.
