Correct Answer: D

Rationale: Diabetic ketoacidosis (DK
A) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.

Rationale: Documenting the findings is the most appropriate action since a respiratory rate of 35 breaths per minute falls within the normal range for a 12-month-old infant. There is no immediate need for interventions such as administering oxygen or notifying the healthcare provider. Reassessing the respiratory rate in 15 minutes is unnecessary as the rate is within normal limits.

Correct Answer: A

Rationale: For a 7-month-old baby with diarrhea and signs of moderate dehydration who can still drink, the most appropriate fluid is Oral Rehydration Solution (ORS). ORS helps in rehydrating the body and replenishing lost electrolytes, making it essential in managing dehydration due to diarrhea.

Correct Answer: C

Rationale: Inability to lie supine is a specific sign of lower respiratory infection. This condition can cause discomfort or difficulty in breathing when lying flat, leading to a preference for an upright or semi-upright position. While cough and fever are common symptoms of respiratory infections, the inability to lie supine is more indicative of lower respiratory involvement.
