Correct Answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome as they help reduce inflammation and decrease proteinuria. Antihypertensive agents are used to manage high blood pressure often associated with kidney disease but are not the primary treatment for this condition. Long-term diuretics are not typically used in the management of minimal change nephrotic syndrome as they can worsen fluid and electrolyte imbalances. Increasing fluids to promote diuresis is not recommended in this condition as it can lead to further fluid retention and edema.

Correct Answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, the majority of the volume should be administered within the first 8 hours to prevent shock and maintain perfusion. Choice A is incorrect because crystalloids are typically administered first in fluid resuscitation for burns. Choice B is incorrect as fluid replacement in burn patients is primarily determined by the extent of the burn injury rather than the type of burn. Choice D is incorrect as the goal for hourly urine output in burn patients is generally higher, aiming for 1-2 mL/kg/hr in children to ensure adequate renal perfusion and prevent dehydration.

Correct Answer: D

Rationale: Severe coughing spells are a hallmark clinical manifestation of pertussis. Pertussis, also known as whooping cough, is characterized by paroxysms of rapid, consecutive coughs followed by a distinctive 'whoop' sound as the patient gasps for air. This intense coughing can lead to vomiting, exhaustion, and sometimes a characteristic 'whoop' sound. Inspiratory stridor (Choice B) is more commonly associated with croup, not pertussis. Nasal congestion (Choice C) is not a typical feature of pertussis. While a cough is present in pertussis, the specific type of cough described in Choice A (dry, hacking cough) is not the predominant feature observed in pertussis.

Correct Answer: D

Rationale: The most crucial factor in successful toilet training is the parents' commitment to consistently work with their child. While parents' attitude and willingness are important, the key is their dedication to the process. The child's motivation and ability are also significant but rely heavily on parental guidance and support. Therefore, the correct choice is the parents' commitment to work on toilet training.

Correct Answer: D

Rationale: When feeding a newborn with choanal atresia, the nurse can anticipate that the infant may take only part of the feeding before pausing for air. This is due to the fact that infants with choanal atresia struggle to breathe through their nose while feeding. Choice A is incorrect as choking typically involves a more severe airway obstruction. Choice B is incorrect because difficulty swallowing is not the primary concern in choanal atresia. Choice C is incorrect as the issue is not related to hunger cues but rather the physiological challenges associated with breathing while feeding.
