Rationale: Hemophilia A is due to missing factor VIII, not IX (which is Hemophilia B, aka Christmas disease). Option B (False) is correct.
Question 2 of 5
A 3-year-old boy... sinus infections and pneumonia... loose, greasy, mucousy stools... Which of the following studies is most effective to determine the diagnosis?
Correct Answer: D
Rationale: Cystic fibrosis causes recurrent respiratory infections and malabsorptive, greasy stools due to pancreatic insufficiency. Sweat chloride test (D) diagnoses it. Bronchoscopy (A) is invasive and less specific.
Question 3 of 5
After administering a vaccine, clients should remain present for a minimum of:
Correct Answer: C
Rationale: The CDC and ACIP recommend that patients remain under observation for at least 15 minutes after vaccination to monitor for immediate adverse reactions, such as anaphylaxis, which is rare but can occur. This duration balances safety with practicality, as most serious reactions manifest within this timeframe. Choice A (60 minutes) and B (45 minutes) are excessively long for routine monitoring, while Choice D (10 minutes) is insufficient to catch all potential early reactions.
Question 4 of 5
Which is the most contagious communicable disease?
Correct Answer: D
Rationale: Measles is considered the most contagious vaccine-preventable disease, with a basic reproduction number (R0) of 12-18, meaning one infected person can infect 12-18 others in a susceptible population. It spreads via respiratory droplets and airborne transmission. Polio (R0 ~5-7), mumps (R0 ~4-7), and pertussis (R0 ~5-17) are also contagious but less so than measles, which has a higher attack rate and requires >90% vaccination coverage for herd immunity.
Question 5 of 5
If a client refuses a recommended vaccination what should you do?
Correct Answer: B
Rationale: Clients have the right to refuse medical treatment, including vaccines, based on autonomy and bodily integrity (e.g., U.S. Patients’ Bill of Rights). However, healthcare providers should document the refusal in the client’s chart (Choice B) to record the discussion, education provided, and decision for legal and clinical continuity. Choice A is insufficient as it omits documentation, Choice C is inappropriate unless mandated by public health (e.g., outbreak), and Choice D, while part of education, is not the primary action.
