The primary care NP sees a 5-year-old child for a prekindergarten physical examination. The child's parents do not have immunization records, and a local record search does not provide proof of vaccinations, although the parent thinks the child may have had some vaccines several years ago. The NP's initial action will be to:
- A. assume the child is unvaccinated and start the full series.
- B. check titers for all vaccine-preventable diseases.
- C. administer a single dose of each vaccine today.
- D. consult state immunization registry again.
Correct Answer: A
Rationale: The correct answer is A because without records, assuming unvaccinated and starting the series ensures protection. Choice B is incorrect (titers not practical initially). Choice C is wrong (single doses insufficient). Choice D is inaccurate (registry already checked).
Drugs that should be avoided in children include:
- A. Acetaminophen
- B. Aspirin
- C. Amoxicillin
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because aspirin is avoided in children under 16 due to its association with Reye's syndrome, a rare but serious liver and brain condition, per AAP recommendations. Choice A is incorrect as acetaminophen is safe and commonly used. Choice C is wrong because amoxicillin is a standard pediatric antibiotic with a good safety profile. Choice D is incorrect since only aspirin fits the avoidance criterion.
A 4-month-old infant has a viral illness with high fever and cough. The infant's parent asks the NP about what to give the infant to help with symptoms. The NP should prescribe which of the following?
- A. Aspirin to treat the fever
- B. Acetaminophen as needed
- C. Dextromethorphan for coughing
- D. An antibiotic to prevent increased infection
Correct Answer: B
Rationale: The correct answer is B because acetaminophen is safe for infants to reduce fever. Choice A is incorrect (aspirin risks Reye’s syndrome). Choice C is wrong (dextromethorphan risks respiratory depression). Choice D is inaccurate (antibiotics don’t treat viral illness).
Clinical judgment in prescribing includes:
- A. Factoring in the cost to the patient of the medication prescribed
- B. Always prescribing the newest medication available for the disease process
- C. Handing out drug samples to poor patients
- D. Prescribing all generic medications to cut costs
Correct Answer: S
Rationale: Choice A is correct because clinical judgment involves balancing efficacy, safety, and cost to ensure patients can afford and adhere to treatment, which is critical for successful outcomes. Choice B is incorrect as always choosing the newest medication ignores evidence-based practice; newer drugs may lack long-term data or be unnecessarily expensive. Choice C is wrong because distributing samples isn't a sustainable prescribing strategy and may not meet ongoing needs. Choice D is also incorrect since mandating generics could compromise efficacy if a brand-name drug is clinically necessary.
Generic drugs may differ from brand-name drugs in:
- A. Active ingredient
- B. Inactive ingredients
- C. Therapeutic effect
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because generics may use different inactive ingredients (e.g., fillers, dyes) affecting appearance or tolerability, but not efficacy, per FDA rules. Choice A is incorrect as active ingredients must be identical. Choice C is wrong because therapeutic effects are equivalent. Choice D is incorrect since only inactive ingredients differ.
