Match the following drug classification with the appropriate drug,

The nurse should contact the provider before administering furosemide because the patient has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Furosemide is a diuretic that can cause potassium loss and worsen hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and fatigue. The nurse should also monitor the patient’s blood pressure, weight, and urine output, as furosemide can lower blood pressure and cause dehydration.

Choice A. Administer medication is wrong because the nurse should not give furosemide without checking with the provider first, as it could be harmful to the patient with low potassium.

Choice C. Hold medication is wrong because the nurse should not withhold furosemide without a valid reason or an order from the provider, as it could cause fluid overload and worsen the patient’s condition.

Choice D. Give potassium supplement is wrong because the nurse should not give potassium supplement without an order from the provider, as it could cause hyperkalemia or interact with other medications.

Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling.However, diuretics may also lower the blood pressure by reducing the blood volume and the cardiac output. This can cause symptoms such as dizziness, fatigue, or fainting.Hypotension is defined as a systolic blood pressure lower than 90 mmHg or a diastolic blood pressure lower than 60 mmHg.

Choice A is wrong because fluid retention is the opposite of what diuretics do. Diuretics increase the urine output and decrease the fluid accumulation in the body.

Choice C is wrong because hyperglycemia is not a common side effect of diuretics. Hyperglycemia is a condition where the blood sugar level is too high.Diuretics may affect the blood sugar level in some cases, but usually not significantly.

Choice D is wrong because diarrhea is not a typical side effect of diuretics.

Diarrhea is a condition where the stool is loose and watery.Diuretics may cause some gastrointestinal discomfort, such as nausea or cramps, but not diarrhea.

Normal ranges for blood pressure are 120/80 mmHg for systolic/diastolic in healthy adults, and 140/90 mmHg or higher for hypertension.Normal ranges for blood sugar are 70-100 mg/dL for fasting glucose, and less than 140 mg/dL for postprandial glucose.
