Correct Answer: A

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload, which can exacerbate their condition. Monitoring fluid intake and output helps prevent complications such as heart failure. Encouraging activity may be important, but it should be done cautiously and within limits due to the child's cardiac condition. Promoting a high-calorie diet is not typically a priority in congenital heart disease care unless there are specific indications. Maintaining oxygen therapy may be necessary in some cases but is not the primary intervention for managing congenital heart disease.

Correct Answer: C

Rationale: The correct answer is C: A ready source of glucose should be available. When managing type 1 diabetes, it is crucial to have a quick source of glucose readily available in case of hypoglycemia. This ensures that the adolescent can quickly raise their blood sugar levels to prevent complications. Choices A, B, and D are incorrect as they do not address the immediate need for glucose in managing hypoglycemia. While it is important for meals to be consumed regularly and in a controlled manner, specifying that they should be eaten at home or foods weighed using a gram scale is not as critical as ensuring a quick source of glucose in emergency situations.

Correct Answer: B

Rationale: The correct answer is B: Signs of dehydration. Assessing for signs of dehydration is crucial in infants with hypertrophic pyloric stenosis (HPS) because they are at high risk due to frequent vomiting. Dehydration can lead to serious complications if not promptly addressed. Choices A, C, and D are not the priority assessments for HPS. While the quality of the cry can provide some information on the infant's distress level, dehydration assessment takes precedence. Coughing up feedings may not be specific to HPS, and characteristics of the stool, although important in general assessments, are not the priority in this situation.

Correct Answer: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing accounts for individual variations in drug metabolism and distribution, ensuring a more precise and safer medication administration. Choices A, B, and C are incorrect as they do not address the importance of weight-based dosing in children, potentially leading to inappropriate dosing and safety concerns.

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.
