An 18 year old patient is in the clinic to receive a tetanus vaccine after sustaining a laceration injury. The nurse learns that the patient, who works in a day care center, has not had any vaccines for more than 10 years. Which vaccine will the nurse expect to administer?

Correct Answer: D

Rationale: For an 18-year-old with a laceration and no vaccines for over 10 years, Tdap is recommended. It updates tetanus (Td) and adds pertussis protection, critical for daycare workers due to pertussis risk to infants. Td (Choice C) lacks pertussis, DT/DTaP (Choices A, B) are for children <7 years.

Correct Answer: B

Rationale: The BCG vaccine prevents severe TB (e.g., miliary TB) in infants in high-risk areas (WHO), though not routine in the U.S. Measles, polio, and mumps vaccines target other diseases, making Choice B correct.

Correct Answer: D

Rationale: Puzzles with large pieces enhance fine motor skills (grasping, coordination) in toddlers (1-3 years), per developmental guidelines. Blocks (Choice A) aid gross motor, others are less specific.

Correct Answer: C

Rationale: Sitting upright is often cited for young children (document answer), though lateral recumbent is also standard (AAP) to flex the spine. Contextually, Choice C is correct per the document.

Correct Answer: C

Rationale: Rolling over (front to back) is expected by 6 months (AAP). Walking (12-18 months), speaking sentences (2 years), and tricycling (3 years) occur later.
