A nurse is assessing the patient's home medication use. After listening to the patient list current medications, the nurse asks what priority question?
- A. Do you take any generic medications?
- B. Are any of these medications orphan drugs?
- C. Are these medications safe to take during pregnancy?
- D. Do you take any over-the-counter medications?
Correct Answer: D
Rationale: It is important for the nurse to specifically question use of over-the-counter medications because patients may not consider them important. The patient is unlikely to know the meaning of orphan drugs unless they too are health care providers. Safety during pregnancy, use of a generic medication, or classification of orphan drugs are things the patient would be unable to answer but could be found in reference books if the nurse wishes to research them.

- C. Prolonged use of this medication can cause hyperglycemia.

A 68-year-old patient who must take antihistamines for severe allergies is planning a vacation to Mexico. The nurse will encourage the patient to:
- A. Avoid sightseeing during the hottest part of the day
- B. Discontinue the antihistamines if he becomes extremely restless
- C. Decrease the dosage of the drugs if he experiences excessive thirst
- D. Continue taking the antihistamines even if he begins to hallucinate
Correct Answer: A
Rationale: Antihistamines can decrease sweating by blocking cholinergic receptors, placing the patient at high risk for heat stroke. Avoiding the hottest part of the day will help prevent dehydration and heat prostration. Extreme restlessness could indicate Parkinson-like syndrome not usually associated with antihistamines. Excessive thirst is characteristic of hyperglycemia, and hallucinations are associated with drugs that affect neurologic functioning. Nurses should never tell patients to decrease or discontinue a drug unless the prescriber has instructed them to do so.
