The nurse is caring for a child who has had a unilateral long-leg cast applied for the correction of club foot.
What is the most important action for the nurse to perform?
Monitor the capillary refill of the toes.
Compare the temperature of both legs.
Observe for spontaneous movement.
Check the femoral pulses.
The Correct Answer is A
Choice A rationale
Monitoring the capillary refill of the toes is crucial when a child has a long-leg cast applied. This is because it helps assess the adequacy of circulation to the foot, which can be compromised by the cast. If the capillary refill is delayed (more than 2 seconds), it could indicate poor blood flow to the area, which could lead to serious complications such as tissue necrosis.
Choice B rationale
Comparing the temperature of both legs can provide information about circulation and inflammation. However, it is not the most important action in this case. While a significant difference in temperature could indicate a problem, it is not as direct an indicator of circulatory status as capillary refill.
Choice C rationale
Observing for spontaneous movement can provide information about nerve function. If the child is not moving the toes, it could indicate nerve damage. However, lack of movement could also be due to discomfort from the cast and is not as direct an indicator of circulatory status as capillary refill.
Choice D rationale
Checking the femoral pulses can provide information about circulation to the leg. However, the femoral pulse is proximal to the cast and may not accurately reflect circulation to the foot. Therefore, it is not the most important action in this case.

Correct Answer is C
Explanation
Choice A rationale
Variance in blood pressure across extremities is not typically associated with ventricular septal defects (VSDs). VSDs are characterized by a hole in the heart that allows oxygen-rich blood to move back into the lungs instead of being pumped to the rest of the body.
Choice B rationale
Hypotension is not a common symptom of VSDs. Instead, these defects can cause increased blood pressure in the lungs due to the abnormal flow of blood.
Choice C rationale
Tachycardia, or a rapid heart rate, is a common symptom of VSDs, especially in cases where the defect is medium or large. This is because the heart needs to work harder to pump blood, leading to an increased heart rate.
Choice D rationale
While pulse oximetry readings within defined limits could be seen in small VSDs, in larger defects or those causing heart failure, oxygen saturation levels might be lower due to the abnormal circulation of blood.
Correct Answer is B
Explanation
Choice A rationale
Seizure activity typically presents with symptoms such as convulsions, loss of consciousness, or abnormal behavior, which are not described in the scenario.
Choice B rationale
Arrhythmia, or an abnormal heart rhythm, could potentially cause a sudden drop in oxygen saturation and cyanosis. It could also lead to a rapid response team being called.
Choice C rationale
Increased oxygen demand could potentially lead to low oxygen saturation. However, it would not typically cause cyanosis or require the rapid response team to be called unless it was associated with another condition such as heart or lung disease.
Choice D rationale
Acidosis, or a high level of acid in the body, could potentially cause low oxygen saturation. However, it would not typically cause cyanosis or require the rapid response team to be called unless it was severe or associated with another condition.
