A mother asks the practical nurse about the immunization schedule for whooping cough.
Which is the recommended schedule that the practical nurse should convey?

Choice A rationale

Impulsive and hyperactive behaviors are typically associated with conditions such as attention-deficit/hyperactivity disorder (ADHD), which involves neurodevelopmental differences affecting executive function and impulse control. While these behaviors can sometimes lead to accidents, they are not a direct sign of secondary enuresis.

Choice B rationale

Involuntary passage of feces, known as encopresis, is a distinct elimination disorder characterized by the repeated passage of stool into inappropriate places, often due to chronic constipation and overflow incontinence. It is a separate condition from enuresis, which specifically refers to involuntary urination.

Choice C rationale

Increased thirst, or polydipsia, is a common symptom of conditions like diabetes mellitus or diabetes insipidus, where the body attempts to compensate for fluid imbalances or high glucose levels. While some medical conditions causing enuresis might also involve increased thirst, it is not a direct sign of enuresis itself.

Choice D rationale

Declining invitations for sleepovers is a behavioral manifestation often observed in children with enuresis. The fear of embarrassment and shame associated with involuntary urination during sleep can lead them to avoid situations where their condition might be exposed, such as overnight stays at friends' houses.

Choice A rationale

Monitoring serum electrolytes is the top priority for an infant with congenital adrenal hyperplasia (CAH). This condition involves an enzymatic defect that impairs cortisol and aldosterone synthesis, leading to salt wasting due to insufficient aldosterone. This can cause life-threatening hyponatremia and hyperkalemia, requiring urgent intervention. Normal ranges are typically sodium 135-145 mEq/L and potassium 3.5-5.0 mEq/L.

Choice B rationale

Checking for hypothermia is important for any neonate or infant, as they have immature thermoregulation. While a general nursing intervention, it is not the most specific or life-threatening concern directly related to the pathophysiology of congenital adrenal hyperplasia, which primarily involves electrolyte imbalances.

Choice C rationale

Assessing for urinary tract infection is a relevant general health assessment, especially in infants with ambiguous genitalia, due to potential anatomical variations. However, while important for overall health, it does not address the immediate, life-threatening metabolic derangements associated with congenital adrenal hyperplasia.

Choice D rationale

Recording daily weights is crucial for assessing fluid balance in infants, particularly those at risk for dehydration or fluid retention. While important for monitoring overall health and fluid status, it is secondary to the critical need to monitor and correct acute electrolyte imbalances that can rapidly become life-threatening in CAH.
