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?
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 C
Explanation
Choice A: When the client has ankle edema is not the most important time for the nurse to assess DTRs, as this is a common finding in pregnancy and does not indicate a neurological or vascular problem. This is a distractor choice.
Choice B: Within the first trimester of pregnancy is not the most important time for the nurse to assess DTRs, as this is a routine assessment that can be done at any time during pregnancy and does not reflect any specific risk or complication. This is another distractor choice.
Choice C: If the client has an elevated blood pressure is the most important time for the nurse to assess DTRs, as this can indicate preeclampsia, a serious condition that can cause seizures, stroke, and organ damage. DTRs can help detect hyperreflexia, which is a sign of increased intracranial pressure and impending eclampsia. Therefore, this is the correct choice.
Choice D: During admission to labor and delivery is not the most important time for the nurse to assess DTRs, as this is a standard assessment that can be done at any stage of labor and does not signify any urgent or emergent situation. This is another distractor choice.
Correct Answer is B
Explanation
Choice A reason: Marking an outline of the "olive-shaped" mass in the right epigastric area is not a priority nursing action. The mass is caused by hypertrophy of the pyloric sphincter, which obstructs gastric emptying and causes projectile vomiting. The mass may not be palpable in all cases.
Choice C reason: Monitoring amount of intake and infant's response to feedings is important, but not the highest priority. The infant may have difficulty feeding due to nausea, vomiting, and abdominal pain.
Choice D reason: Instructing parents regarding care of the incisional area is a post-operative nursing action, not a pre-operative one. The parents will need to learn how to keep the incision clean and dry, monitor for signs of infection, and administer pain medication as prescribed.
