What is the correct nursing response to a mother who asks, "How can I get rid of the baby's cradle cap?"

Choice A rationale

Applying medication after a bath is correct because the skin is hydrated and warm, which enhances the absorption of the topical agent. The open pores and softened stratum corneum allow for better penetration of the medication, maximizing its therapeutic effect on the underlying skin condition.

Choice B rationale

Rubbing the ointment in a circular motion can cause mechanical irritation and friction to the compromised skin, which can worsen the rash. The correct technique is to gently smooth the medication over the affected area in a thin, even layer.

Choice C rationale

Increasing the amount of cream without a prescription can lead to systemic absorption and potential adverse effects, especially with corticosteroid creams. The dosage is carefully prescribed to balance therapeutic effects with minimal risk of side effects. Over-application can also cause skin thinning.

Choice D rationale

Using powder and cornstarch is not recommended for skin conditions, as these substances can trap moisture and debris, creating a medium for bacterial or fungal growth. This can exacerbate the underlying skin condition and increase the risk of secondary infections.

Choice A rationale

While a cough is a known side effect of lisinopril due to bradykinin accumulation, a new-onset cough in a client with heart failure and hypertension could also signal worsening heart failure, particularly pulmonary edema. Assessing lung sounds for crackles and monitoring oxygenation is paramount to differentiate between these two distinct etiologies and guide appropriate intervention.

Choice B rationale

Changing antihypertensives is a medical decision made by the provider. The nurse's role is to assess the client's symptoms and provide objective data to the provider. Switching medications without a thorough assessment could be premature and might delay the diagnosis of a more serious condition like decompensated heart failure.

Choice C rationale

Obtaining vital signs is a fundamental nursing action, but it is not the most appropriate initial action in this specific clinical scenario. The report of a new cough in a client with heart failure necessitates a targeted assessment of the respiratory system, including auscultating lung sounds and evaluating for signs of hypoxemia, to rule out a life-threatening complication.

Choice D rationale

While a cough is a known side effect of lisinopril, dismissing the symptom could be dangerous. The cough may not be benign; it could be an early sign of pulmonary congestion from heart failure. The nurse must perform a comprehensive assessment to ensure the client's safety and to avoid misattributing a serious finding to a common medication side effect.
