The nurse is preparing to administer insulin intravenously. Which statement about the administration of intravenous insulin is true?

Insulin is never given intravenously.

Only regular insulin can be administered intravenously.

Insulin aspart or insulin lispro can be administered intravenously, but there must be a 50% dose reduction.

Any form of insulin can be administered intravenously at the same dose as that ordered for subcutaneous administration.

Answer and Explanation

The Correct Answer is B

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 A

Explanation

Choice A reason: This is correct because hemoglobin A1C level reflects the average blood glucose level over the past 2 to 3 months. It is a reliable indicator of the patient's glycemic control and adherence to the antidiabetic therapy. The goal for most patients with type 2 diabetes is to keep the hemoglobin A1C level below 7%.

Choice B reason: This is incorrect because serum insulin level is not a good measure of the patient's adherence to the antidiabetic therapy, as it may vary depending on the type, dose, and timing of the insulin or oral antidiabetic agents. Serum insulin level may also be affected by other factors, such as stress, infection, or exercise.

Choice C reason: This is incorrect because fingerstick fasting blood glucose level only reflects the blood glucose level at a single point in time. It does not provide information about the patient's long-term glycemic control or adherence to the antidiabetic therapy. Fingerstick fasting blood glucose level may also be influenced by the patient's diet, activity, or medication intake before the test.

Choice D reason: This is incorrect because hemoglobin level is not related to the patient's adherence to the antidiabetic therapy, as it measures the amount of oxygen-carrying protein in the red blood cells. Hemoglobin level may be affected by conditions such as anemia, dehydration, or blood loss.

A. Expect to see a response from the medication within one week. B. Women should avoid touching this medication. C. PSA levels will increase while taking this medication. D. Avoid drinking grapefruit juice when taking this medication.

Correct Answer is B

Explanation

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.
