Correct Answer is D
Explanation
A. Haemophilus Influenza Type B (HIB) Vaccine and TDAP. HIB vaccine reduces the incidence of meningitis caused by Haemophilus influenzae, but TDAP does not target pathogens responsible for meningitis.
B. Inactivated polio vaccine (IPV) and Pneumococcal Conjugate Vaccine (PCV). IPV prevents polio but has no impact on meningitis incidence. PCV is correct for preventing Streptococcus pneumoniae meningitis.
C. DTAP and Varicella Vaccine. DTAP does not prevent bacterial meningitis, and varicella vaccine prevents chickenpox, not meningitis.
D. Pneumococcal Conjugate Vaccine (PCV) and Haemophilus Type B (HIB Vaccine). These vaccines directly prevent bacterial meningitis caused by Streptococcus pneumoniae and Haemophilus influenzae, which were previously leading causes of meningitis in children.
Correct Answer is ["A","D"]
Explanation
A. Clear the area of hard objects: This prevents injury to the child during the seizure.
B. Place a tongue depressor in the child's mouth: This is contraindicated as it can cause injury to the oral cavity or obstruct the airway.
C. Place the child in prone position: This position is unsafe during a seizure and could compromise the airway. The lateral position is recommended to reduce aspiration risk.
D. Loosen restrictive clothing: Loosening clothing promotes easier breathing and comfort during the seizure.
