Correct Answer: B

Rationale: Allowing the child to play with a favorite toy while taking the medication is the best approach to gain cooperation. This strategy can help distract and calm the child during the medication administration process. Choice A may not be as effective with a young child who may not fully understand the explanation. Offering a reward (choice C) may reinforce negative behavior and create a dependency on rewards for cooperation. Giving the medication with food (choice D) may not always be appropriate and may not address the cooperation aspect.

Correct Answer: B

Rationale: The correct answer is monitoring fluid balance. In a child with diabetes insipidus, the primary concern is excessive urination and fluid loss, which can lead to dehydration. Monitoring fluid balance is crucial to prevent dehydration and maintain electrolyte balance. Administering insulin (Choice A) is not indicated in diabetes insipidus, as this condition is not related to insulin deficiency. Administering diuretics (Choice C) should be avoided as it can exacerbate fluid loss in a child already at risk for dehydration. While monitoring vital signs (Choice D) is important, the priority intervention in this situation is monitoring fluid balance to prevent complications associated with dehydration.

Correct Answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.

Correct Answer: C

Rationale: The correct answer is Chickenpox (varicella). This viral disease typically starts with malaise and a highly pruritic rash that begins on the abdomen and then spreads to the face and proximal extremities. Chickenpox can result in serious complications such as pneumonia and encephalitis. Rubella (German measles) presents with a milder rash and is less pruritic than chickenpox. Rubeola (measles) is characterized by a rash that spreads from the head to the trunk. Scarlet fever is caused by group A Streptococcus bacteria and is not a viral illness.

Correct Answer: A

Rationale: Encouraging parents to express their concerns is the most supportive intervention as it allows them to process their emotions and provides an opportunity for the nurse to offer appropriate support and information. This choice focuses on validating the parents' feelings and creating an open communication channel. Choices B and C are incorrect as they can hinder the parents' emotional processing and may provide false reassurance. Choice D, showing postoperative photographs, may not be appropriate at this stage as it might not address the parents' current emotional needs and could induce anxiety or unrealistic expectations.
