Correct Answer is C
Explanation
A. Minimizing movement of the limbs is not a recommended action during a seizure. It is important to allow the seizure to run its course while ensuring the safety of the child.
B. Placing the child in a prone position is not recommended during a seizure. The child should be placed in a lateral (side-lying) position to help prevent aspiration and maintain an open airway.
C. This is the correct action. Clearing the area of hard objects helps prevent injury to the child during the seizure. It is important to create a safe environment.
D. Inserting a tongue blade between the teeth is not recommended. This action can cause injury to the child's mouth or teeth. It is a myth that individuals can swallow their tongue during a seizure.
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.
