A nurse is caring for an adolescent client who has a long history of diabetes mellitus and is being admitted to the emergency department confused, flushed, and with an acetone odor on the breath. Diabetic ketoacidosis is suspected. The nurse should anticipate using which of the following types of insulin to treat this client?

Insulin glargine

Regular insulin

Insulin detemir

NPH insulin

Answer and Explanation

The Correct Answer is B

Choice A reason: Insulin glargine is not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 24 hours and no peak effect. It is used to provide basal insulin coverage and prevent hyperglycemia.

Choice B reason: Regular insulin is the type of insulin to use for diabetic ketoacidosis, as it is a short-acting insulin that has an onset of 30 to 60 minutes and a peak of 2 to 4 hours. It is used to lower the blood glucose level rapidly and correct the acidosis.

Choice C reason: Insulin detemir is also not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 12 to 24 hours and no peak effect. It is also used to provide basal insulin coverage and prevent hyperglycemia.

Choice D reason: NPH insulin is also not the type of insulin to use for diabetic ketoacidosis, as it is an intermediate-acting insulin that has an onset of 2 to 4 hours and a peak of 4 to 12 hours. It is used to provide intermediate insulin coverage and prevent hyperglycemia.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because constipation is not a common or serious adverse effect of antihistamines. However, the patient should increase their fluid and fiber intake and exercise regularly to prevent constipation.

Choice B reason: This is incorrect because abdominal cramps are not a common or serious adverse effect of antihistamines. However, the patient should avoid spicy or fatty foods and take the antihistamine with food or milk to prevent stomach irritation.

Choice C reason: This is correct because drowsiness is one of the most common and bothersome adverse effects of antihistamines. The patient should avoid driving or operating machinery if they experience drowsiness and take the antihistamine at bedtime.

Choice D reason: This is incorrect because decreased libido is not a common or serious adverse effect of antihistamines. However, the patient should inform their provider if they experience any sexual dysfunction or mood changes while taking the antihistamine.

A. Reduced effectiveness of the sildenafil B. Significant increase in pulse rate C. Increased risk of bleeding D. Significant decrease in blood pressure

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.
