The nurse recognizes that respiratory depression is a risk with some cough suppressants. Which preparation has the least risk of causing respiratory depression?
1. Codeine-based
2. Codeine with bromodiphenhydramine (Ambenyl)
3. Hydrocodone with homatropine (Hycodan)
4. Dextromethorphan (Delsym)
Correct Answer: 4
Rationale 1: Codeine is a narcotic, and even low-dose preparations have the potential for respiratory depression, particularly if attention is not directed toward proper dosing.
Rationale 2: Codeine is a narcotic, and even low-dose preparations like Ambenyl have the potential for respiratory depression, particularly if attention is not directed toward proper dosing.
Rationale 3: Hycodan (with the narcotic hydrocodone) has a greater potential for respiratory depression than another cough suppressant.
Rationale 4: Delsym (dextromethorphan) is a nonnarcotic preparation with the lowest potential for respiratory depression.
Global Rationale: There are almost no adverse effects at therapeutic doses of dextromethorphan. Sedation and dizziness have occurred at moderate doses. In abuse situations the drug can cause CNS toxicity with a wide variety of symptoms, including slurred speech, ataxia, hyperexcitability, stupor, respiratory depression, seizures, coma, and toxic psychosis. The remaining products are all narcotic-based with risk for respiratory depression.
