Correct Answer: C

Rationale: The correct answer is C: Influenza. The influenza vaccine is produced using egg-based technology, so individuals with a severe egg allergy are at risk of an allergic reaction if vaccinated with the influenza vaccine. This is due to the potential presence of egg proteins in the vaccine. Choices A, B, and D are not contraindicated in children with severe egg allergy. The MMR and Varicella vaccines do not pose a risk for children with egg allergies, and the Hepatitis B vaccine is also safe for these individuals.

Correct Answer: A

Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.

Correct Answer: C

Rationale: The correct answer is C: Hyperlipidemia. Children with nephrotic syndrome often present with hyperlipidemia due to altered lipid metabolism, making it a primary concern in these patients. Hypotension (choice A) is not a primary concern in nephrotic syndrome. Hyperkalemia (choice B) and hypocalcemia (choice D) are not typically associated with nephrotic syndrome and are less likely to be primary concerns in these patients.

Correct Answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

Correct Answer: B

Rationale: The correct answer is B: All of the above. Citrus, spicy foods, and peppermint are known to exacerbate GER symptoms by increasing acid production or relaxing the lower esophageal sphincter. Therefore, these foods should be avoided by a child with GER disease. Bananas, on the other hand, are generally safe and do not contribute to acid reflux. Choice B is correct because all the mentioned foods can worsen GER symptoms, while bananas are considered safe.
