Correct Answer: B

Rationale: The correct answer is B: 'Ensure that the antibiotic is administered as prescribed.' It's crucial to stress the importance of following the prescribed antibiotic regimen to prevent infections and promote proper healing after cardiac surgery. Choice A is incorrect because it does not address the fundamental aspect of adherence to the prescription. Choice C is incorrect as shaking the bottle may not be necessary for all antibiotics and is not a critical instruction in this context. Choice D is incorrect as storage instructions are not directly related to the administration of the antibiotic as prescribed, which is the primary concern in this scenario.

Correct Answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.

Correct Answer: D

Rationale: Correct answer: When feeding a newborn with choanal atresia, the nurse should anticipate that the infant may take only part of the feeding. This behavior is due to the condition causing difficulty in breathing through the nose while feeding, prompting the infant to pause for air. Choice A, 'Chokes on the feeding,' is incorrect as it does not specifically relate to the feeding behavior expected in choanal atresia. Choice B, 'Has difficulty swallowing,' is also incorrect because the issue in choanal atresia is primarily related to breathing rather than swallowing. Choice C, 'Does not appear to be hungry,' is not the typical behavior seen in infants with choanal atresia; they may still display hunger cues but struggle with feeding due to the condition.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial for managing asthma symptoms as certain foods can trigger or worsen asthma attacks. Monitoring dietary intake helps ensure the child receives proper nutrition and avoids triggers. Assessing sleep patterns (Choice A) may be relevant but not as directly impactful on asthma management. Academic performance (Choice C) and behavior at home (Choice D) are important aspects of a child's overall health but are not as directly related to asthma management as dietary intake.

Correct Answer: C

Rationale: Infants with Down syndrome are at increased risk of congenital heart defects. Therefore, assessing for abnormal heart sounds is crucial during the physical examination. Bulging fontanels are not typically associated with Down syndrome and may indicate increased intracranial pressure. Stiff lower extremities are not a common finding in Down syndrome and may suggest other musculoskeletal issues. Unusual pupillary reactions are not typically linked to Down syndrome and may be indicative of neurological problems instead.
