The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?

Answer and Explanation

The Correct Answer is ["30"]

First, we need to find the concentration of insulin in the IV solution, which is the ratio of insulin units to saline volume. To do this, we use the given information that the IV solution contains 100 units in 250 ml. So, we divide 100 by 250 and get 0.4 units/ml.

Next, we need to calculate the infusion rate in ml/hour for the ordered dose of 12 units/hour. To do this, we use the ratio of insulin units to saline volume, which is 0.4 units/ml. So, we set up a proportion as follows:

0.4/1=12/x

To solve for x, we cross-multiply and get 0.4 x = 12. Then, we divide both sides by 0.4 and get x = 30. So, the infusion rate is 30 ml/hour.

Therefore, the nurse should program the infusion pump to deliver 30 ml/hour..

Correct Answer is A

Explanation

Choice A reason: This is correct because it addresses both the physical and emotional needs of the child and the mother. The nurse should provide comfort and reassurance to the mother and explain that occasional accidents are normal and not a sign of failure.

Choice B reason: This is incorrect because it implies that the mother is incompetent and needs external help. The nurse should first establish rapport and trust with the mother before suggesting any resources or interventions.

Choice C reason: This is incorrect because it suggests that there is something wrong with the child's kidneys, which may alarm and offend the mother. The nurse should not jump to conclusions without assessing the child's history and symptoms.

Choice D reason: This is incorrect because it generalizes and stereotypes boys as being slower than girls in toilet training. The nurse should not make assumptions based on gender and should respect individual differences.

A. Instruct the client to increase his intake of oral fluids until the skin flushing is relieved. B. Advise the client to place one nitroglycerin tablet under his tongue as a precaution. C. Tell the client to have someone bring him to an emergency department immediately. D. Reassure the client that facial flushing is a common side effect of the medication.

Correct Answer is D

Explanation

Choice A: Increasing oral fluids may help with hydration, but it will not reduce skin flushing caused by lisinopril. Lisinopril is an angiotensin-converting enzyme (ACE. inhibitor that dilates blood vessels and lowers blood pressure. Flushing occurs due to increased blood flow to the skin.

Choice B: Nitroglycerin is a vasodilator that relaxes smooth muscle in blood vessels and reduces chest pain caused by angina. It is not indicated for skin flushing caused by lisinopril. Moreover, nitroglycerin can lower blood pressure further and cause hypotension, headache, dizziness, and fainting.

Choice C: Going to an emergency department is not necessary for skin flushing caused by lisinopril. Flushing is not a sign of an allergic reaction or anaphylaxis, which would require immediate medical attention. Flushing is also not a symptom of a heart attack or stroke, which would present with other signs such as chest pain, shortness of breath, arm numbness, or slurred speech.

Choice D: Reassuring the client that facial flushing is a common side effect of lisinopril is the best action for the nurse to take. Flushing is not harmful or dangerous, and it usually subsides within a few hours. The nurse should explain the mechanism of action of lisinopril and its benefits for lowering blood pressure and preventing angina. The nurse should also advise the client to monitor his blood pressure regularly and report any signs of hypotension, such as dizziness, lightheadedness, or fainting.
