A nurse is reinforcing teaching with a client about healthful sleep habits.
Which of the following statements should the nurse identify as an indication that the client needs further instructions?

This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.

Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.

Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.

Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.

Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.

Increasing regular weight-bearing activities can help prevent osteoporosis by stimulating bone formation and improving muscle strength. Weight-bearing activities are those that make your bones and muscles work against gravity, such as walking, jogging, dancing, or lifting weights.

Choice A is wrong because protecting the client’s bones with strict bedrest can actually increase the risk of osteoporosis by reducing bone density and muscle mass. Bedrest should be avoided unless medically necessary.

Choice B is wrong because providing the client with assisted range of motion exercises twice daily is not enough to prevent osteoporosis. While these exercises can help maintain joint mobility and flexibility, they are not weight bearing and do not stimulate bone formation.

Choice C is wrong because decreasing the amount of calcium in the client’s diet can also increase the risk of osteoporosis. Calcium is an essential mineral for bone health and adults need 700mg a day, which can be obtained from foods such as dairy products, leafy green vegetables, tofu, and dried fruit. Vitamin D is also important for bone health as it helps the body absorb calcium.
