A nurse is providing discharge teaching to a client who has peripheral arterial disease (PAD). Which of the following instructions should the nurse include in the teaching?

Hypokalemia is a low serum potassium level, usually below 3.5 mEq/L. It can be caused by diuretics that increase potassium excretion, such as thiazides or loop diuretics. Potassium is essential for normal muscle and nerve function, and hypokalemia can impair cardiac, skeletal, and smooth muscle activity. Symptoms of hypokalemia include fatigue, weakness, muscle cramps, arrhythmias, constipation, and hyporeflexia.

1. Dyspnea is difficulty or labored breathing that can be caused by various respiratory or cardiac conditions, such as asthma, pneumonia, pulmonary edema, or heart failure. It is not a specific sign of hypokalemia, although severe hypokalemia can affect respiratory muscle function and cause respiratory failure.
2. Oliguria is a reduced urine output, usually less than 400 mL per day or 30 mL per hour. It can be caused by various renal or fluid balance disorders, such as acute kidney injury, dehydration, or shock. It is not a specific sign of hypokalemia, although severe hypokalemia can impair renal function and cause renal failure.
3. Pitting edema is a swelling of the tissues that leaves an indentation when pressed with a finger. It can be caused by various fluid retention disorders, such as heart failure, liver cirrhosis, or nephrotic syndrome. It is not a specific sign of hypokalemia, although severe hypokalemia can affect fluid and electrolyte balance and cause edema.

Turn the client's head to the side.

The nurse should turn the client's head to the side first to prevent aspiration of oral secretions and maintain a patent airway. This is the priority action according to the airway, breathing, and circulation (ABC) principle.

Check the client's motor strength is wrong because it is not the priority action and it is not feasible during a seizure. The nurse should check the client's motor strength after the seizure to assess for any neurological deficits or postictal weakness.

Document the time the seizure began is wrong because it is not the priority action and it can be done later. The nurse should document the time, duration, type, and characteristics of the seizure, but only after ensuring the client's safety and well-being.

Loosen the clothing around the client's waist is wrong because it is not the priority action and it may not be necessary. The nurse should loosen any tight clothing that could impair breathing or circulation, but only after securing the airway and protecting the head from injury.
