Correct Answer is B

Explanation

Choice A rationale

Severe motor dysfunction indicates the degree of impairment but does not determine the extent of successful habilitation. Habilitation depends on various factors, including individual capabilities, intervention quality, and environmental support.

Choice B rationale

Brain damage with CP is not progressive, meaning it does not worsen over time. However, the effects and manifestations can vary, leading to a range of functional outcomes. This provides a realistic and hopeful perspective for the child's future.

Choice C rationale

CP is indeed one of the most common permanent physical disabilities in children, but this statement does not directly address the mother's concern about the potential progression of impaired movements.

Choice D rationale

The continued development of the brain lesion is not a characteristic of CP. The brain damage is static, meaning it does not change, although its effects may become more apparent as the child grows and develops.

A. Withhold this dose. B. Administer a half dose now. C. Give another dose. D. Mix the next dose with food.

Correct Answer is A

Explanation

Choice A rationale

Withholding the dose is the safest action to avoid potential overdose or toxicity. Digoxin has a narrow therapeutic window, and administering an additional dose without knowing how much was absorbed could lead to dangerous side effects.

Choice B rationale

Administering a half dose now is not recommended because it is unclear how much of the original dose was absorbed. This could result in either an insufficient dose or an overdose, leading to ineffective treatment or potential toxicity.

Choice C rationale

Giving another dose is not safe because there is a risk of overdosing the infant. Digoxin toxicity can cause serious complications, and it is crucial to avoid administering more medication until the next scheduled dose.

Choice D rationale

Mixing the next dose with food is not appropriate because it does not address the immediate concern of potential overdose. The priority is to withhold the dose and monitor the infant's condition.
