The nurse understands that hypospadias refers to what urinary anomaly?

The correct answer is choice C: Oral rehydration solution (ORS).

Choice A rationale:

Clear liquids, 1 to 2 ounces at a time, might not be sufficient to adequately rehydrate a child with severe dehydration. Clear liquids lack the necessary electrolytes and glucose content to effectively combat dehydration and replace lost fluids.

Choice B rationale:

Administration of antidiarrheal medication is not the initial step in managing severe dehydration caused by acute diarrhea and vomiting. Antidiarrheal medications can slow down the gastrointestinal motility, which may exacerbate the problem by delaying the elimination of the causative agent and prolonging the dehydration.

Choice C rationale:

Oral rehydration solution (ORS) is the recommended initial intervention for managing severe dehydration caused by acute diarrhea and vomiting. ORS contains the appropriate balance of electrolytes (sodium, potassium, chloride) and glucose to replace lost fluids and electrolytes, thereby helping to rehydrate the child effectively. It is absorbed even when digestion is impaired due to the illness.

Choice D rationale:

Intravenous fluids might be necessary if the child's condition is very severe and oral intake cannot be maintained. However, it's not the first-line intervention. Oral rehydration is preferred whenever feasible because it is less invasive and can be administered even in mild to moderate dehydration cases.

The correct answer is choice A. The cuff bladder covers 50% to 66% of the length of the upper arm.

Choice A rationale:

Selecting a blood pressure cuff with a bladder that covers 50% to 66% of the length of the upper arm is the appropriate criterion for determining the cuff size for a 2-year-old boy. This range ensures accurate blood pressure measurement by ensuring a proper fit on the arm. If the cuff bladder is too small or too large, it can result in inaccurate readings.

Choice B rationale:

The label "toddler" on the cuff might be helpful in identifying the intended age group, but it doesn't provide precise measurements for cuff sizing. Relying solely on a label might not account for variations in arm sizes within the toddler age group.

Choice C rationale:

The cuff bladder width being 40% of the circumference of the upper arm might not be as accurate as the length-based criterion. A cuff that fits the arm's length is more critical in ensuring proper inflation and accurate blood pressure measurement.

Choice D rationale:

The cuff bladder length covering 80% to 100% of the circumference of the upper arm might result in an excessively large cuff for a 2-year-old, which can lead to inaccurate readings. Length-based sizing is more appropriate for accuracy in this scenario.
