Rationale: In a toddler presenting with sudden hoarseness, holding or pointing to their neck, and continuous cough, the nurse should be particularly concerned about respiratory tract obstruction caused by a foreign body. These symptoms are indicative of a possible foreign body in the airway, which can lead to serious complications and requires immediate attention to ensure the toddler's airway remains patent and unobstructed.

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: D

Rationale: A growth hormone assessment is necessary to definitively diagnose growth hormone deficiency, which could be a possible cause of Bubunyo's growth delay despite adequate nutrition. This test will help determine if Bubunyo's growth issues are related to a lack of growth hormone production.

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: Status asthmaticus is a life-threatening condition characterized by a severe and prolonged asthma attack that does not respond to standard treatments. It requires immediate medical intervention to prevent respiratory failure and potential fatality. Reactive airway disease, intrinsic asthma, and extrinsic asthma do not specifically denote the severity and unresponsiveness to treatment seen in status asthmaticus.
