A nurse is teaching a client who has benign prostatic hypertrophy and has a new prescription for finasteride. Which of the following instructions should the nurse include in the teaching?
Expect to see a response from the medication within one week.
Women should avoid touching this medication.
PSA levels will increase while taking this medication.
Avoid drinking grapefruit juice when taking this medication.
The Correct Answer is B
Choice A reason: This is incorrect because the patient may not see a response from the medication for at least six months. The patient should continue taking the medication as prescribed and follow up with the provider regularly.
Choice B reason: This is correct because finasteride can cause birth defects in male fetuses if it is absorbed through the skin or ingested by pregnant women. The patient should wear gloves when handling the tablets and avoid contact with crushed or broken tablets.
Choice C reason: This is incorrect because PSA levels will decrease while taking this medication. PSA stands for prostate-specific antigen, which is a marker for prostate cancer. The patient should inform the provider that they are taking finasteride before having a PSA test, as it may affect the results.
Choice D reason: This is incorrect because grapefruit juice does not interact with finasteride. However, the patient should avoid alcohol and other medications that may affect the liver while taking finasteride.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because insulin can be given intravenously in certain situations, such as diabetic ketoacidosis, hyperglycemic hyperosmolar state, or perioperative care.
Choice B reason: This is correct because regular insulin is the only type of insulin that can be administered intravenously, as it is a short-acting insulin that has a rapid onset and peak. Other types of insulin, such as intermediate-acting or long-acting, are not suitable for intravenous use, as they have a delayed onset and peak and may cause hypoglycemia.
Choice C reason: This is incorrect because insulin aspart and insulin lispro are rapid-acting insulins that have a faster onset and peak than regular insulin. They are not recommended for intravenous use, as they may cause severe hypoglycemia. They are usually given subcutaneously before meals to control postprandial blood glucose levels.
Choice D reason: This is incorrect because not all forms of insulin can be administered intravenously, as explained above. Only regular insulin can be given intravenously, and the dose may differ from the subcutaneous dose depending on the patient's blood glucose level and insulin sensitivity.
Correct Answer is B
Explanation
Choice A reason: Hyperkalemia is not the correct answer. Hyperkalemia is a high level of potassium in the blood. Corticosteroids do not cause hyperkalemia, but rather hypokalemia. Hyperkalemia may be caused by other factors such as renal failure, acidosis, or potassium-sparing diuretics.
Choice B reason: Hypokalemia is the correct answer. Hypokalemia is a low level of potassium in the blood. Corticosteroids can cause hypokalemia by increasing the excretion of potassium and sodium in the urine. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and digoxin toxicity.
Choice C reason: Hypermagnesemia is not the correct answer. Hypermagnesemia is a high level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypermagnesemia may be caused by other factors such as renal failure, excessive antacid use, or magnesium-containing laxatives.
Choice D reason: Hypomagnesemia is not the correct answer. Hypomagnesemia is a low level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypomagnesemia may be caused by other factors such as malnutrition, alcoholism, or diuretic use.
