A nurse is preparing to administer lispro insulin to a client who has type 1 diabetes mellitus. Which of the following actions should the nurse take?
Administer with short-acting insulin.
Assess for hypoglycemia 4 hr after the insulin injection.
Inject the insulin 15 min before a meal.
Monitor for polyuria.
The Correct Answer is C
Choice A reason: This is incorrect because lispro insulin is a rapid-acting insulin that does not need to be administered with another type of insulin. However, the patient may need a long-acting or intermediate-acting insulin to provide basal coverage throughout the day.
Choice B reason: This is incorrect because lispro insulin has a peak action of 30 to 90 min after the injection, which means that the patient is at the highest risk of hypoglycemia during this time. The nurse should assess for hypoglycemia more frequently than 4 hr after the injection.
Choice C reason: This is correct because lispro insulin has a fast onset of action of 15 to 30 min after the injection, which means that the patient should eat a meal within 15 min of the injection to prevent hypoglycemia.
Choice D reason: This is incorrect because polyuria is a sign of hyperglycemia, not hypoglycemia. The nurse should monitor for polyuria before the insulin injection, as it may indicate that the patient's blood glucose level is high.

Correct Answer is D
Explanation
Choice A reason: This is incorrect because sildenafil and nitrates do not affect each other's effectiveness, but rather their side effects. Sildenafil is a phosphodiesterase-5 inhibitor that enhances the effect of nitric oxide, which causes vasodilation and increases blood flow to the penis. Nitrates are vasodilators that also increase nitric oxide levels and reduce the workload of the heart.
Choice B reason: This is incorrect because sildenafil and nitrates do not cause a significant increase in pulse rate, but rather a decrease. This is because the vasodilation caused by both drugs lowers the blood pressure and the cardiac output, which reduces the heart rate.
Choice C reason: This is incorrect because sildenafil and nitrates do not increase the risk of bleeding, unless they are combined with other drugs that affect the blood clotting process, such as anticoagulants or antiplatelets.
Choice D reason: This is correct because sildenafil and nitrates can cause a significant decrease in blood pressure when taken together, as they both cause vasodilation and increase nitric oxide levels. This can lead to hypotension, dizziness, fainting, or even a heart attack or stroke. The patient should avoid taking sildenafil and nitrates within 24 hours of each other.
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.
