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.

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: In this scenario, the correct action is to hold the medication and notify the healthcare provider. Digoxin should be withheld if the infant's heart rate is below 100 beats per minute. Administering digoxin in this situation can further slow down the heart rate in infants with heart failure, leading to potential adverse effects. Reassessing the heart rate in 30 minutes is not the best immediate action to take, as prompt notification and withholding of the medication are crucial. Administering the medication as prescribed or giving half the dose can exacerbate the situation by potentially further lowering the heart rate.

Correct Answer: C

Rationale: The correct answer is C. Applying warm compresses to a sprained ankle within the first 24 hours is incorrect as it can increase swelling and inflammation. Instead, cold compresses are recommended to help reduce swelling and pain. Option A, keeping the leg elevated, helps in reducing swelling. Option B, wrapping the ankle in an elastic bandage, provides support. Option D, using an ice pack in intervals, is effective in reducing swelling and pain. Therefore, the statement about applying warm compresses indicates the need for further instruction.

Correct Answer: B

Rationale: The correct answer is explaining the association between drinking soda and dental caries. Soda consumption can lead to tooth decay and cavities, so it is crucial to educate the mother about this to prevent dental issues in the child.
