Correct Answer: D

Rationale: The correct answer is D, Hemophilus influenzae type B (Hib) vaccine. Hib vaccine is crucial in preventing epiglottitis, a serious respiratory condition caused by Haemophilus influenzae type b bacteria. This vaccine is recommended for toddlers to protect them from developing epiglottitis. Choices A, B, and C are incorrect because while they are important vaccines for children, they do not specifically target the prevention of epiglottitis, unlike the Hib vaccine.

Correct Answer: A

Rationale: Nonpathologic cyanosis in newborns shortly after birth is typically present in the feet and hands, known as acrocyanosis. This is a normal finding due to the immature peripheral circulation in newborns. Cyanosis of the bridge of the nose, circumoral area, and mucous membranes indicates generalized cyanosis, which suggests a potential underlying distress or major abnormality. Therefore, choice A is correct as it describes the expected location for nonpathologic cyanosis in newborns, while choices B, C, and D represent areas associated with abnormal cyanosis.

Correct Answer: D

Rationale: High fever, especially in very young infants, or the presence of a stiff neck can indicate a serious infection requiring immediate attention. A fever lasting more than 3 days also warrants medical evaluation.

Correct Answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

Correct Answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.
