The home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give this patient related to fluid intake?

Choice A reason: Patient stopped taking the medication 2 days ago is the most important information to report to the health care provider. Prednisone is a corticosteroid medication that suppresses the immune system and reduces inflammation. Prednisone also affects the production of cortisol, a hormone that regulates the stress response, blood pressure, blood sugar, and metabolism. Prednisone should not be stopped abruptly, as this can cause adrenal insufficiency, a condition where the adrenal glands cannot produce enough cortisol. Adrenal insufficiency can cause symptoms such as fatigue, weakness, nausea, vomiting, low blood pressure, and hypoglycemia. The patient should be instructed to resume taking the prednisone and taper the dose gradually under the supervision of the health care provider.

Choice B reason: Patient has not been taking the prescribed vitamin D is not as important as choice A, but still requires further education by the nurse. Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and phosphorus, and maintain bone health. Prednisone can interfere with the metabolism of vitamin D and cause bone loss, osteoporosis, and fractures. The patient should be advised to take the prescribed vitamin D supplement and eat foods rich in vitamin D, such as fatty fish, egg yolks, cheese, and fortified milk.

Choice C reason: Patient has bilateral 2+ pitting ankle edema is not as critical as choice A, but still needs to be monitored by the nurse. Ankle edema is swelling of the ankles due to fluid accumulation in the tissues. Prednisone can cause ankle edema by increasing the sodium and water retention in the body, and reducing the potassium excretion by the kidneys. The patient should be assessed for signs of fluid overload, such as weight gain, shortness of breath, and crackles in the lungs. The patient should also be encouraged to limit the intake of salt and fluids, and elevate the legs when sitting or lying down.

Choice D reason: Patient's blood pressure is 148/94 mm Hg is not as urgent as choice A, but still needs to be addressed by the nurse. Blood pressure is the force of blood against the walls of the arteries. Prednisone can increase the blood pressure by stimulating the renin-angiotensin-aldosterone system, a hormonal system that regulates the blood volume and pressure. The patient should be advised to check the blood pressure regularly, and report any readings above 140/90 mm Hg to the health care provider. The patient should also be counseled to follow a healthy lifestyle, such as exercising, quitting smoking, reducing stress, and eating a balanced diet low in sodium, fat, and cholesterol.

Choice A reason: This statement is false. IV morphine sulfate is a pain medication that can be given as needed to the postoperative patient. It does not affect the serum sodium level.

Choice B reason: This statement is false. Dextrose 5% in 0.9% sodium chloride is a hypertonic solution that can be used to treat hyponatremia, or low serum sodium level. It provides both glucose and sodium to the patient.

Choice C reason: This statement is true. 5% dextrose in water is a hypotonic solution that can cause further dilution of the serum sodium level. It can worsen the hyponatremia and increase the risk of cerebral edema and seizures.

Choice D reason: This statement is false. Neurologic assessment Q2 hours is a necessary intervention for a patient with hyponatremia, as it can monitor for signs of neurologic deterioration such as confusion, lethargy, or coma.
