A nurse is preparing to administer immunizations to a child who has an allergy to eggs. The nurse should know that an allergy to eggs is a contraindication for which of the following immunizations?

Choice A rationale:
Weighing the infant every day on the same scale at the same time is crucial in monitoring excess fluid volume in congestive heart failure. Sudden weight gain can indicate fluid retention, a common sign of worsening heart failure. Daily weight monitoring helps in early detection and timely intervention.
Choice B rationale:
Notifying the physician when weight gain exceeds more than 20 g/day might be too late for intervention. Daily weight monitoring is essential to detect trends and intervene promptly to manage excess fluid volume.
Choice C rationale:
Placing the infant in a car seat to minimize movement is not directly related to managing excess fluid volume in congestive heart failure. It is essential for safety during transportation but does not address the nursing diagnosis.
Choice D rationale:
Administering digoxin as ordered by the physician is a medical intervention for congestive heart failure. While important, the nursing diagnosis is related to excess fluid volume, and the focus should be on nursing interventions such as monitoring daily weights.

Choice A rationale
Pediculosis capitis, also known as head lice, is a common condition in children. One of the definitive indications of this condition is the presence of firmly attached white particles on the hair, which are the eggs or “nits” of the lice.
Choice B rationale
While itching and scratching of the head can be a symptom of pediculosis capitis, it is not a definitive indication as it can be caused by other conditions such as dandruff or dermatitis.
Choice C rationale
Patchy areas of hair loss are not typically associated with pediculosis capitis. They could indicate a different condition, such as alopecia areata or tinea capitis.
Choice D rationale
Thick yellow-crusted lesions on a red base are not a symptom of pediculosis capitis. This description is more consistent with impetigo, a bacterial skin infection.
