A nurse is caring for an infant who has rotavirus. Which of the following findings indicates that the infant is moderately dehydrated?
Respiratory rate 28/min
Capillary refill 1 second
Weight loss 7%
Bradycardia
The Correct Answer is A
A. A respiratory rate of 28 breaths per minute indicates increased respiratory effort, which can be a sign of moderate dehydration. The infant may be trying to compensate for fluid
loss.
B. Capillary refill of 1 second is within the normal range (less than 2 seconds). It is not indicative of moderate dehydration.
C. Weight loss of 7% is a significant amount of weight loss and is indicative of severe dehydration, not moderate dehydration. Moderate dehydration is usually defined as 5- 10% weight loss.
D. Bradycardia (slow heart rate) is not typically associated with dehydration. In fact, tachycardia (fast heart rate) is a more common sign of dehydration.

Correct Answer is A
Explanation
A. Applying warm compresses can help to improve blood flow and relieve pain in areas affected by a sickle cell crisis. This is a beneficial intervention.
B. Decreasing fluid intake is not recommended. Maintaining hydration is important in the management of sickle cell disease, as it helps to prevent dehydration and reduces the risk of sickling.
C. Furosemide is a diuretic and is not typically used in the treatment of a sickle cell crisis.
It is not an appropriate intervention in this situation.
D. Contact precautions are not necessary for a sickle cell crisis. This crisis is not a contagious condition. Standard precautions for infection control should be followed.
Correct Answer is ["2.2"]
Explanation
To calculate the dose of ondansetron for a child who is receiving chemotherapy, the nurse needs to use the following formula:
Dose (mL) = (Dose ordered in mg / Dose available in mg) x Volume available in mL
In this case, the dose ordered in mg is 0.15 mg/kg x 29.4 kg, which equals 4.41 mg. The dose available in mg is 4 mg, and the volume available in mL is 2 mL. Therefore, the dose in mL is:
Dose (mL) = (4.41 mg / 4 mg) x 2 mL Dose (mL) = 2.205 mL
The nurse should round the answer to the nearest tenth, so the final answer is 2.2 mL. The nurse should administer 2.2 mL of ondansetron IV to the child who is receiving chemotherapy.
