Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the most important nursing intervention is to administer pain medication. Pain management is crucial in alleviating the intense pain experienced by the patient. Administering oxygen (Choice A) may be necessary in some cases to improve oxygenation, but pain relief takes precedence during a vaso-occlusive crisis. Monitoring fluid intake (Choice C) is important for hydration but is not the priority during a crisis. Encouraging physical activity (Choice D) is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and tissue damage.

Correct Answer: B

Rationale: Assessing compliance with treatment regimens is crucial in managing eczema effectively and preventing flare-ups. This involves ensuring that the child is following the prescribed treatment plan, which may include medication application, skincare routines, and lifestyle modifications. Changing a bandage on a cut would not be a routine part of an eczema check-up unless there was a specific wound related to eczema. Discussing systemic corticosteroid therapy may be part of the management plan for severe eczema cases but would not be the primary focus during a routine check-up. Assessing the child's fluid volume, while important in general health assessments, is not directly related to managing eczema specifically.

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: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL. This range is considered safe to prevent overdistension and potential harm to the child's rectum. Choices A, C, and D exceed the safe range for a 2-year-old child and can lead to complications such as bowel perforation or electrolyte imbalances.

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.
