Correct Answer: B

Rationale: The correct answer is B. Applying diaper cream during each diaper change is important to prevent skin breakdown in infants with rotavirus. Rotavirus can cause diarrhea, which can lead to skin irritation. Avoiding feeding the baby for 12 hours (choice A) can lead to dehydration and is not appropriate. Giving water between feedings (choice C) can further contribute to dehydration. Applying warm compresses (choice D) may provide comfort but does not address the specific issue of preventing skin breakdown associated with rotavirus.

Correct Answer: C

Rationale: The correct answer is C: Administer an incentive spirometer. Using an incentive spirometer helps prevent atelectasis by encouraging lung expansion after surgery. Encouraging deep breathing exercises (choice A) is beneficial but may not be as effective as an incentive spirometer. Encouraging the client to cough (choice B) helps with airway clearance but does not directly prevent atelectasis. Assisting the client to ambulate (choice D) is important for preventing complications such as deep vein thrombosis, but it is not the most effective intervention for preventing atelectasis.

Correct Answer: D

Rationale: The key management strategy for diabetic ketoacidosis (DKA) involves a comprehensive approach that includes administering insulin to lower blood glucose levels, monitoring blood glucose levels to ensure they are within the target range, and administering IV fluids to correct dehydration and electrolyte imbalances. Choosing 'All of the above' as the correct answer is the most appropriate because all three interventions are essential components of DKA management. Administering insulin alone without addressing fluid status and monitoring blood glucose could lead to complications. Similarly, solely focusing on IV fluids or blood glucose monitoring without insulin administration would not effectively manage DKA.

Correct Answer: A

Rationale: The client with low blood glucose needs immediate assessment to ensure that the orange juice has corrected the hypoglycemia. Monitoring the effectiveness of the intervention for low blood glucose is the priority. The other options, such as a client scheduled for a procedure in 1 hour, a client with fluid remaining in the IV bag, and a client who received pain medication 30 minutes ago, do not require immediate assessment like the client with low blood glucose.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators and monitor oxygen levels. Asthma management involves using bronchodilators to help open the airways and improve breathing. Monitoring oxygen levels is essential to ensure the patient is getting enough oxygen. Choice B, encouraging deep breathing exercises, can be helpful for some respiratory conditions but is not a key intervention for managing an acute asthma attack. Choice C, providing corticosteroids and monitoring for respiratory distress, is important for long-term asthma management and severe exacerbations but is not the immediate key intervention during an acute attack. Choice D, providing antihistamines and monitoring blood pressure, is not typically indicated for asthma management as asthma is primarily an airway disease, not a histamine-mediated condition.
