Correct Answer is D
Explanation
A. Pneumococcal conjugate vaccine (PCV): This vaccine is generally completed before the age of 5, so it is not typically administered at this stage.
B. Hepatitis B (HBV): The HBV series is usually completed during infancy and early childhood, so it is not needed at 5 years if the child is up to date.
C. Haemophilus influenzae type B (Hib): Hib is typically completed by 18 months of age and is not required for pre-kindergarten.
D. Measles, mumps, and rubella (MMR): A second dose of MMR is typically required at 4-6 years, aligning with pre-kindergarten vaccination schedules.
Correct Answer is A
Explanation
A. Speak slowly while facing the child: Facing the child helps them see lip movements and facial expressions, which aids communication.
B. Talk directly into the child's impaired ear: Shouting or talking directly into the ear is unhelpful and can distort sound further.
C. Stand above the child's eye level when speaking: Standing above the child can make communication difficult. The nurse should be at eye level to establish effective communication.
D. Speak loudly to the child: Speaking loudly can distort sound and is not helpful for a hearing-impaired child.
