Question 1 of 5
A 39-year-old man with long-standing allergies has no health insurance and simply takes over-the-counter diphenhydramine for symptom relief. He has no other medical problems but uses this medication up to four times per day. Which of the following effects of this medication is possible to be experienced by this patient?
Correct Answer: B
Rationale: Diphenhydramine's frequent use risks dizziness , an anticholinergic effect. Appetite enhancement isn't typical. Hypotension and bradycardia are less common. Urinary retention (E) occurs but isn't listed. Dizziness reflects CNS depression from high dosing.
Question 2 of 5
Which statement is accurate regarding attention-deficit hyperactivity disorder (ADHD)?
Correct Answer: B
Rationale: ADHD in girls often presents as anxiety/withdrawal, versus boys' hyperactivity-per research-though diagnosis favors boys. It's not bipolar-mania/depression differ. Boys dominate diagnosis stats. It's early, not late, onset. Gender presentation accuracy reflects ADHD nuance.
Question 3 of 5
The nurse provides care for elders in an assisted living facility. What does the nurse assess as a primary contributing factor for drug toxicity in the elderly?
Correct Answer: B
Rationale: Dehydration, common in elders from reduced thirst, lowers drug clearance (e.g., renal function drops), risking toxicity-key in pharmacokinetics. Alcohol abuse varies, not primary. Constipation affects excretion less than fluid status. Stomach acid decreases, not increases, with age. Dehydration's impact on volume and clearance drives toxicity risk.
Question 4 of 5
The following are examples of prodrugs:
Correct Answer: D
Rationale: All these drugs require metabolic activation to exert their therapeutic effects, making them prodrugs.
Question 5 of 5
While assessing a patient who is receiving intravenous digitalis, the nurse recognizes that the drug has a negative chronotropic effect. How would this drug effect be evident in the patient?
Correct Answer: B
Rationale: Digitalis has a negative chronotropic effect, meaning it slows down the heart rate. This can be evident in a patient by observing a decrease in their heart rate. Chronotropy refers to the heart rate or rhythm of the heart. Digitalis works by inhibiting the sodium-potassium pump in the heart muscle cells, leading to an increase in intracellular calcium levels. This results in a decreased heart rate and improved contractility of the heart muscle. Therefore, a decreased heart rate is the expected effect when a patient is receiving intravenous digitalis.
