Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.

Correct Answer: B

Rationale: The most effective way to prevent hypoglycemia during physical activity in a child with type 1 diabetes is to ensure they eat a snack before exercising. Eating a snack before exercise helps maintain blood glucose levels by providing additional glucose for energy during physical activity, reducing the risk of hypoglycemia. Giving extra insulin before exercise (Choice A) can increase the risk of hypoglycemia as it lowers blood glucose levels further. Limiting physical activity (Choice C) is not recommended as exercise is important for overall health. Monitoring blood glucose levels after exercise (Choice D) is essential but does not directly prevent hypoglycemia during physical activity.

Correct Answer: D

Rationale: Encouraging the child to use the bathroom before bed is a helpful recommendation to prevent nighttime bedwetting. Bedwetting can sometimes reoccur due to stress or other factors, and ensuring the child empties their bladder before sleeping may reduce the likelihood of bedwetting episodes. Choice A is incorrect because while bedwetting is common in children, it is essential to provide practical solutions rather than just reassurance. Choice B is not the best option for a child who has recently started bedwetting again after being dry, as it may not address the underlying cause. Choice C is inappropriate and harmful as punishing the child for bedwetting can lead to psychological distress and worsen the situation.

Correct Answer: C

Rationale: Hypertension is a serious complication of glomerulonephritis, as it can lead to further renal damage. A blood pressure reading of 150/95 mm Hg is elevated and should be reported promptly to the healthcare provider for immediate management to prevent complications. Dark-colored urine can be a common symptom of glomerulonephritis due to blood in the urine but is not as urgent as managing hypertension. Mild periorbital edema can also be seen in glomerulonephritis but is not as concerning as elevated blood pressure. Urine output of 250 mL in 24 hours indicates oliguria, which is a concern, but addressing hypertension takes priority to prevent further renal damage.

Correct Answer: D

Rationale: The correct answer is D. RSV is highly contagious, even without direct contact. It is important to prevent the spread of the virus to other children, so the infected child should not attend the birthday party to avoid exposing other children to RSV. This is crucial to protect the health of other children who may be more vulnerable to the virus. Choices A, B, and C are incorrect. Choice A is incorrect as RSV remains contagious for a period of time, and precautions should be taken to prevent its spread. Choice B is incorrect because the age limit specified is not a reliable measure to prevent transmission. Choice C is incorrect as wearing a mask may not be sufficient to prevent the spread of RSV in a social setting like a birthday party.
