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: Increased intestinal peristalsis is not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which stimulate the parasympathetic nervous system. Adrenergic agonist drugs activate the sympathetic nervous system, which decreases intestinal motility.
Choice B reason: Bronchial constriction is also not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which cause bronchoconstriction and increased secretions. Adrenergic agonist drugs cause bronchodilation and decreased secretions.
Choice C reason: Increased heart rate is an effect of adrenergic agonist drugs, which stimulate the beta-1 receptors in the heart, causing increased cardiac output and blood pressure. This is why adrenergic agonist drugs are used to treat conditions such as shock, cardiac arrest, and heart failure.
Choice D reason: Constricted pupils is not an effect of adrenergic agonist drugs, but rather of cholinergic drugs, which cause miosis or pupil constriction. Adrenergic agonist drugs cause mydriasis or pupil dilation.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because the nurse should inject air into the NPH insulin vial after injecting air into the regular insulin vial. This prevents contamination of the regular insulin with the NPH insulin.
Choice B reason: This is correct because the nurse should inject air into the regular insulin vial first, then into the NPH insulin vial, before withdrawing the regular insulin. This equalizes the pressure in the vials and facilitates the withdrawal of the insulin.
Choice C reason: This is incorrect because the nurse should not replace the needle for withdrawal with a safety needle. The same needle should be used for injecting air and withdrawing insulin from both vials.
Choice D reason: This is incorrect because the nurse should withdraw 10 units of insulin from the regular insulin vial after injecting air into both vials. This prevents mixing of the NPH insulin with the regular insulin in the vial.
