A client admitted with coronary artery disease (CAD) reports dyspnea at rest. What intervention should the nurse prioritize?
- A. Providing a walker to aid in ambulation
- B. Elevating the head of the bed to at least 45 degrees
- C. Performing continuous monitoring of oxygen saturation
- D. Placing an oxygen cannula at the bedside for use if needed
Correct Answer: B
Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

Which of the following patients would be at higher risk of experiencing adverse drug reactions (ADRs):
- A. A 32-year-old male
- B. A 22-year-old female
- C. A 3-month-old female
- D. A 48-year-old male
Correct Answer: C
Rationale: Choice C is correct because a 3-month-old female is at higher risk for ADRs due to immature liver and kidney function, reducing drug metabolism and excretion, increasing toxicity potential. Choice A is incorrect as a healthy 32-year-old male typically has mature systems. Choice B is wrong because a 22-year-old female also has developed metabolism. Choice D is incorrect since a 48-year-old male, unless compromised, has lower risk than an infant.
Strategies to prevent misuse of prescription drugs include:
- A. Using prescription drug monitoring programs
- B. Educating patients about risks
- C. Prescribing the lowest effective dose
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because PDMPs track dispensing, education deters misuse, and lowest doses minimize excess—all proven prevention methods. Choice A is incorrect alone as it's one tool. Choice B is wrong by itself because education is just part. Choice C is incorrect solo since dosing is only one strategy.
When a medication is added to a regimen for a synergistic effect, the combined effect of the drugs is:
- A. The sum of the effects of each drug individually
- B. Greater than the sum of the effects of each drug individually
- C. Less than the effect of each drug individually
- D. Not predictable, as it varies with each individual
Correct Answer: B
Rationale: Choice B is correct because synergy means the combined effect exceeds the sum of individual effects, enhancing therapeutic outcomes beyond additive results. Choice A is incorrect as it describes an additive, not synergistic, effect. Choice C is wrong because synergy doesn't reduce efficacy below individual effects. Choice D is incorrect since synergy is a predictable pharmacological principle, not entirely variable.
Drugs that should be avoided in the elderly include:
- A. Acetaminophen
- B. Amitriptyline
- C. Amoxicillin
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because amitriptyline, a tricyclic antidepressant, is avoided in the elderly (per Beers Criteria) due to anticholinergic effects causing confusion, constipation, and falls. Choice A is incorrect as acetaminophen is safe. Choice C is wrong because amoxicillin is appropriate with dose adjustment. Choice D is incorrect since only amitriptyline fits.
Strategies to avoid counterfeit drugs include:
- A. Purchasing from licensed pharmacies
- B. Checking drug packaging
- C. Avoiding online purchases from unverified sources
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because using licensed pharmacies (regulated supply), checking packaging (authenticity cues), and avoiding unverified online sources (high-risk) all prevent counterfeit drug use, per FDA advice. Choice A is incorrect alone as it's one strategy. Choice B is wrong by itself because packaging is just part. Choice C is incorrect solo since online avoidance is only one method.
