A nurse is assessing a client who has heart failure and is prescribed furosemide. Which of the following findings is an adverse effect of this medication?
Hypokalemia
Hypoglycemia
Weight gain
Increased blood pressure
The Correct Answer is A
Choice A reason: Hypokalemia is a low level of potassium in the blood. Furosemide is a loop diuretic that increases the excretion of water and electrolytes, including potassium. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and digoxin toxicity.
Choice B reason: Hypoglycemia is a low level of glucose in the blood. Furosemide does not affect blood glucose levels or insulin secretion. Hypoglycemia may be caused by other factors such as diabetes medications, fasting, or alcohol intake.
Choice C reason: Weight gain is not an adverse effect of furosemide. Furosemide causes weight loss by reducing fluid retention and edema. Weight gain may be a sign of worsening heart failure or fluid overload.
Choice D reason: Increased blood pressure is not an adverse effect of furosemide. Furosemide lowers blood pressure by decreasing blood volume and cardiac preload. Increased blood pressure may be caused by other factors such as salt intake, stress, or kidney disease.

Correct Answer is C
Explanation
Choice A reason: Vaginal cultures are not necessary for oral contraceptive therapy. They are used to diagnose infections such as bacterial vaginosis, yeast infection, or sexually transmitted diseases.
Choice B reason: Complete blood count is not essential for oral contraceptive therapy. It is used to measure the number and types of blood cells, such as red blood cells, white blood cells, and platelets.
Choice C reason: Serum potassium level is the most important laboratory test for oral contraceptive therapy. This is because some oral contraceptives can increase the risk of hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause serious complications such as cardiac arrhythmias, muscle weakness, and paralysis.
Choice D reason: Pregnancy test is not a laboratory test, but a urine test. It is important to rule out pregnancy before starting oral contraceptive therapy, but it is not the most important test for the nurse to assess.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because insulin glargine has a longer duration than 6 to 10 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.
Choice B reason: This is incorrect because insulin glargine has a longer duration than 3 to 6 hr. Insulin glargine is not a short-acting or rapid-acting insulin that peaks quickly and lasts for a few hours. It is a long-acting insulin that does not have a peak and lasts for up to 24 hr.
Choice C reason: This is incorrect because insulin glargine has a longer duration than 16 to 24 hr. Insulin glargine is a long-acting insulin that can last for up to 24 hr, but not more than that. It is not an ultra-long-acting insulin that can last for more than 24 hr.
Choice D reason: This is correct because insulin glargine has a duration of 18 to 24 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.
