A med-surg patient is scheduled to receive docusate (Colace) at 9am. The night nurse advises the patient had two loose stools during her shift. The nurse would anticipate:

Choice A reason: Advise the client to avoid highfiber foods with the medication is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix does not interact with highfiber foods or affect the digestion directly. Highfiber foods can actually help prevent or treat constipation, which can be a side effect of Lasix. The nurse should encourage the client to eat a balanced and nutritious diet, unless they have any dietary restrictions or allergies.

Choice B reason: Encourage the client to consume a potassium rich diet is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should monitor the serum potassium level and administer potassium supplements or potassiumsparing diuretics as prescribed to prevent hypokalemia. Consuming a potassium rich diet may not be sufficient or safe to correct the potassium imbalance caused by Lasix, especially in clients with kidney impairment or other medications that affect the potassium level.

Choice C reason: Assess the client’s respiratory rate and oxygen saturation is the most appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can help reduce the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should assess the client’s respiratory rate and oxygen saturation to evaluate the severity of the pulmonary edema and the effectiveness of the Lasix therapy. The nurse should also monitor the client’s vital signs, fluid intake and output, and weight to ensure adequate fluid balance and hemodynamic stability.

Choice D reason: Instruct the client to increase fluid intake to prevent dehydration is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can cause dehydration, which can lead to symptoms such as thirst, dry mouth, dark urine, and fatigue. However, increasing fluid intake to prevent dehydration can worsen the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should advise the client to drink enough fluids to maintain hydration, but not to exceed the prescribed fluid restriction, which is usually around 1.52 liters per day. The nurse should also educate the client about the signs and symptoms of dehydration and fluid overload, and when to seek medical attention.

Choice A reason: This is correct. Nausea, vomiting, and diarrhea are the most common side effects of metformin, especially when the drug is started or the dose is increased. These side effects occur because metformin can interfere with the absorption of glucose and other nutrients in the intestines, causing osmotic diarrhea. The nurse should advise the client to take metformin with food, start with a low dose and gradually increase it, and drink plenty of fluids to prevent dehydration. The nurse should also monitor the client for signs of lactic acidosis, a rare but serious complication of metformin that causes severe diarrhea, abdominal pain, muscle cramps, and difficulty breathing.

Choice B reason: This is incorrect. Palpitations are not a common side effect of metformin. Palpitations are the sensation of a rapid, irregular, or pounding heartbeat, which can be caused by various factors, such as stress, anxiety, caffeine, nicotine, or heart problems. Metformin does not affect the heart rate or rhythm directly, but it can lower the blood sugar levels, which can trigger the release of adrenaline, a hormone that can cause palpitations. The nurse should check the client's blood sugar levels and advise the client to eat regular meals and snacks, avoid alcohol and caffeine, and report any chest pain or shortness of breath.

Choice C reason: This is incorrect. Headaches are not a common side effect of metformin. Headaches are the pain or discomfort in the head, scalp, or neck, which can be caused by various factors, such as stress, dehydration, or sinus infection. Metformin does not cause headaches directly, but it can lower the blood sugar levels, which can cause headaches as a symptom of hypoglycemia. The nurse should check the client's blood sugar levels and advise the client to eat regular meals and snacks, drink plenty of water, and take painkillers as needed.

Choice D reason: This is incorrect. Heartburn is not a common side effect of metformin. Heartburn is the burning sensation in the chest or throat, which is caused by the reflux of stomach acid into the esophagus. Metformin does not cause heartburn directly, but it can worsen it if the client already has gastroesophageal reflux disease (GERD), a condition where the lower esophageal sphincter is weak or relaxed and allows the acid to flow back. The nurse should advise the client to take metformin with food, avoid spicy or fatty foods, elevate the head of the bed, and take antacids as needed.
