The nurse is administering a pneumococcal conjugate vaccine to a client. Which of the following is true regarding this type of vaccine? Select ONE that does not apply.

Correct Answer: B

Rationale: The pneumococcal conjugate vaccine (PCV, e.g., PCV13 or PCV15) prevents infections caused by *Streptococcus pneumoniae*, including pneumonia. A: Side effects like erythema, swelling, and pain at the injection site are well-documented. B: PCV is given in a series (typically 4 doses at 2, 4, 6, and 12–15 months), not once with an adulthood booster; boosters like PPSV23 may apply later for high-risk groups, but this is incorrect for PCV’s standard schedule. C: It’s primarily for infants and children per CDC guidelines. D: PCV has no egg-related contraindications (unlike some influenza vaccines). E: It prevents pneumococcal diseases, including pneumonia. Thus, A, C, and E are true.

Correct Answer: D

Rationale: Albuterol, a beta-2 agonist, relaxes bronchial smooth muscle, dilating airways in asthma. Option A is vague. Option B applies to corticosteroids. Option C relates to mucolytics.

Correct Answer: B

Rationale: Down syndrome (trisomy 21) increases hypothyroidism risk; annual thyroid function tests (TSH, T4) are recommended by the AAP. ECG (A) is baseline. Sleep oximetry (C) screens sleep apnea if indicated. Cervical X-rays (D) assess instability, not routine annually.

Correct Answer: B

Rationale: Down syndrome features a transverse palmar crease (simian line). Small tongue (A) is incorrect; macroglossia is typical. Large nose (C) and restricted joints (D) are not characteristic.

Correct Answer: C

Rationale: Craniotabes (soft skull bones) results from vitamin D deficiency in rickets, affecting bone mineralization. Kwashiorkor (A) and Marasmus (B) are malnutrition-related. Scurvy (D) affects collagen, not skull softening.
