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: A

Rationale: Type 1 diabetes typically occurs after pubertal onset. This form of diabetes is most commonly diagnosed in individuals under the age of 30, with a peak incidence in the mid-teens to early 20s. Puberty is a period of hormonal changes and growth, which can trigger the onset of type 1 diabetes due to the stress it places on the body's insulin-producing cells.

Correct Answer: B

Rationale: In the management of diabetic ketoacidosis (DKA), the initial intravenous (IV) fluid of choice is normal saline infusion. Normal saline helps to correct dehydration and electrolyte imbalances commonly seen in DKA patients. It does not contain glucose to prevent worsening hyperglycemia or ketoacidosis. NPH insulin infusion is not the initial treatment for DKA; it is typically used after fluid resuscitation. Potassium infusion may be required in DKA to address electrolyte imbalances, but normal saline is the priority for fluid resuscitation.

Correct Answer: C

Rationale: Cabbage is an example of a goitrogen. Goitrogens are substances that interfere with the normal function of the thyroid gland by inhibiting iodine uptake. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contain compounds that can have this effect and should be consumed in moderation by individuals with hypothyroidism to prevent worsening of their condition.

Correct Answer: B

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.
