A patient has prescriptions for two inhalers. One inhaler is a bronchodilator, and the other is a corticosteroid. Which instruction regarding these inhalers will the nurse give to the patient?

Take the bronchodilator inhaler first.

Take the corticosteroid inhaler first.

Take these two drugs at least 2 hours apart.

It does not matter which inhaler you use first.

Answer and Explanation

The Correct Answer is A

Choice A reason: Taking the bronchodilator inhaler first will help to open up the airways and make it easier for the corticosteroid inhaler to reach the lungs and reduce inflammation. This will improve the effectiveness and safety of the inhalers.

Choice B reason: Taking the corticosteroid inhaler first may not be as effective as taking the bronchodilator inhaler first, because the airways may be constricted and prevent the corticosteroid from reaching the lungs. This may reduce the anti-inflammatory effect of the corticosteroid and increase the risk of side effects.

Choice C reason: Taking these two drugs at least 2 hours apart is not necessary and may not be practical for the patient. The bronchodilator and the corticosteroid can be taken together, as long as the bronchodilator is taken first.

Choice D reason: It does matter which inhaler the patient uses first, because the order of the inhalers can affect their efficacy and safety. The patient should always use the bronchodilator inhaler first, followed by the corticosteroid inhaler.

Correct Answer is A

Explanation

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.

A. Vaginal cultures B. Complete blood count C. Serum potassium level D. Pregnancy test

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.
