What action should the school nurse take to provide secondary prevention for school-aged children?

Choice A rationale
Comparing muscle strength bilaterally is not the most important intervention in this situation. While muscle weakness can be a symptom of hyperkalemia, it is not the most immediate concern. Hyperkalemia can lead to life-threatening cardiac dysrhythmias, which is a more immediate threat to the patient’s life.

Choice B rationale

Observing the color and amount of urine can provide information about the patient’s renal function, which is important in the regulation of potassium. However, this is not the most immediate concern when a patient’s serum potassium level is dangerously high.

Choice C rationale
Determining the apical pulse rate and rhythm is the most important intervention. Hyperkalemia can cause cardiac dysrhythmias, so the nurse should immediately assess the patient’s heart rate and rhythm. The nurse should also place the patient on a cardiac monitor, if not already done, and notify the healthcare provider immediately.

Choice D rationale
Assessing the strength of deep tendon reflexes can provide information about neuromuscular function, which can be affected by hyperkalemia. However, this is not the most immediate concern. The nurse’s priority is to assess and monitor for life-threatening cardiac dysrhythmias.

Choice A rationale
The most crucial intervention for a nurse to include in the care plan of a client with a deep vein thrombosis (DVT) in the left leg who is on a heparin protocol is to monitor for bleeding side effects related to heparin therapy. Heparin is an anticoagulant medication that prevents the formation of blood clots. While it is an effective treatment for DVT, it can also increase the risk of bleeding. Therefore, it is essential for the nurse to closely monitor the client for any signs of bleeding, such as unusual bruising, blood in urine or stool, or bleeding gums.
Choice B rationale
While promoting movement can help prevent a pulmonary embolism (a potential complication of DVT), it is not the most crucial intervention when a client is on a heparin protocol. Excessive movement can potentially dislodge the clot, leading to a pulmonary embolism. Therefore, while movement is important, it should be done under the guidance of a healthcare professional.
Choice C rationale
Checking blood pressure and heart rate at least every 4 hours is a standard nursing intervention for many clients, not just those with DVT. While it is important to monitor these vital signs, it is not the most crucial intervention for a client with DVT on a heparin protocol.
Choice D rationale

Measuring the circumference of each calf can help assess for leg edema, which can be a sign of DVT. However, this is not the most crucial intervention for a client on a heparin protocol. The priority is to monitor for bleeding side effects related to the heparin therapy.
