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.

While assessing a client taking propranolol, which finding should the nurse report to the provider?
- A. Bradycardia
- B. Dry mouth
- C. Constipation
- D. Increased appetite
Correct Answer: A
Rationale: Bradycardia is a significant side effect of propranolol, a beta-blocker that slows the heart rate. It indicates potential cardiovascular complications and should be reported promptly to the healthcare provider for further evaluation and management. Dry mouth, constipation, and increased appetite are common side effects of various medications but are not directly associated with propranolol's mechanism of action.
To reduce medication errors, the Institute of Safe Medication Practices recommends:
- A. Using only brand names on prescriptions
- B. Avoiding the use of 'tall man' lettering
- C. Avoiding the use of error-prone abbreviations
- D. Using decimals instead of fractions when prescribing
Correct Answer: C
Rationale: Choice C is correct because the ISMP recommends avoiding error-prone abbreviations (e.g., ‘U' for units) to prevent misinterpretation and errors, a proven safety strategy. Choice A is incorrect as brand names alone don't reduce errors—generics are standard. Choice B is wrong because ‘tall man' lettering (e.g., LisinOPRIL) helps, not harms. Choice D is incorrect since decimals can confuse (e.g., .5 vs. 0.5)—whole numbers are safer.
Over-the-counter drugs that are safe to use include:
- A. Acetaminophen
- B. Aspirin
- C. Ibuprofen
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because acetaminophen, aspirin, and ibuprofen are safe OTC options for pain/fever when used per guidelines, with well-established profiles. Choice A is incorrect alone as it's one drug. Choice B is wrong by itself because aspirin is just part. Choice C is incorrect solo since ibuprofen is only one option.
The NP chooses to give cephalexin every 8 hours based on knowledge of the drug's:
- A. Propensity to go to the target receptor
- B. Biological half-life
- C. Pharmacodynamics
- D. Safety and side effects
Correct Answer: B
Rationale: Choice B is correct because dosing cephalexin every 8 hours aligns with its biological half-life, the time it takes for half the drug to be eliminated, ensuring steady therapeutic levels. Choice A is incorrect as ‘propensity to target receptor' isn't a standard pharmacokinetic term for dosing decisions. Choice C is wrong because pharmacodynamics (drug effects) informs efficacy, not timing. Choice D is incorrect since safety and side effects influence drug choice, not specifically the 8-hour interval.
The healthcare provider is monitoring a client following cardioversion. Which observation should be of the highest priority to the healthcare provider?
- A. Blood pressure
- B. Status of airway
- C. Oxygen flow rate
- D. Level of consciousness
Correct Answer: B
Rationale: The status of the airway is the highest priority following cardioversion as it ensures proper oxygenation and helps prevent complications such as airway obstruction and respiratory distress. Maintaining a patent airway is crucial for the client's respiratory function and overall well-being immediately after cardioversion. Monitoring the airway ensures that the client can breathe effectively and minimizes the risk of hypoxia and other serious respiratory issues. While blood pressure, oxygen flow rate, and level of consciousness are also important parameters to monitor, they are secondary to ensuring a clear and patent airway for adequate oxygenation.
