Question 1 of 5
The component of our white blood cells that produces antibodies which attack antigens are:
Correct Answer: A
Rationale: B-Lymphocytes (B cells) are the white blood cells responsible for producing antibodies that bind to and neutralize antigens. Upon activation by antigens and helper T cells, B cells differentiate into plasma cells that secrete antibodies. Macrophages (Choice B) engulf pathogens, T-Lymphocytes (Choice C) include helper and cytotoxic types but don’t produce antibodies, and 'Cytotoxics' (Choice D) likely refers to cytotoxic T cells (CD8+), which kill infected cells, not produce antibodies.
Question 2 of 5
A 48-month-old child is scheduled to receive the following vaccines: MMR, Varivax, IPV, and DTaP. The child's parents want the child to receive two vaccines today and the other two in 1 week. To accommodate the parents' wishes, the nurse will administer
Correct Answer: D
Rationale: Live vaccines (MMR, Varivax) must be given simultaneously or separated by 28 days to avoid immune interference. Splitting them by 1 week (Choices A, B, C) violates this rule. Choice D administers MMR and Varivax today (both live) and DTaP and IPV (both inactivated) in 1 week, adhering to CDC spacing guidelines while meeting the parents’ request.
Question 3 of 5
Which vaccine is given soon after birth?
Correct Answer: B
Rationale: The hepatitis B vaccine (HepB) is recommended by the CDC to be given within 24 hours of birth (dose 1), especially to prevent perinatal transmission from infected mothers. Polio (IPV) starts at 2 months, MMR at 12-15 months, and Varicella at 12-15 months, making Choice B the only vaccine administered soon after birth.
Question 4 of 5
What is the normal respiratory rate for a newborn?
Correct Answer: B
Rationale: Newborns have a resting respiratory rate of 20-40 breaths/minute (Nelson’s Pediatrics), though 20-30 (Choice B) is a commonly cited range for calm states. Choices A, C, and D deviate from this norm.
Question 5 of 5
The nurse is assessing a child with suspected dehydration. Which finding indicates severe dehydration?
Correct Answer: A
Rationale: A sunken fontanelle indicates severe dehydration (10%+ loss) in infants (AAP). Pink membranes (Choice B), normal refill (Choice C), and adequate urine (Choice D) suggest hydration.
