A client is receiving 10 mL/hr of a prescribed regular insulin infusion. The label on the bag reads 50 units of regular insulin in 100 mL of 0.9% saline. How many units of insulin is the client receiving every hour? Fill in the blank. Round your answer to the nearest whole number.
5 units/hour
10 units/hour
20 units/hour
15 units/hour
The Correct Answer is A
Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate
Plugging in the given values, we get:
units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10
units of insulin per hour = 5
Therefore, the client is receiving 5 units of insulin every hour.
Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.
Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.
Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale: A/V fistula assessment is not concerning because a positive bruit and thrill indicate adequate blood flow through the fistula. A dry dressing with scant amount of blood is expected after hemodialysis.
Choice B rationale: The client's low blood pressure could indicate hypotension, which can be critical, especially after hemodialysis. It may contribute to the client's reported dizziness and fatigue.
Choice C rationale: The client’s pulse is irregular which may indicate cardiac arrhythmia. Choice D rationale: Anuria, the absence of urine output, is a significant concern. It could indicate kidney dysfunction or inadequate clearance of waste products, which may have implications following hemodialysis.
Choice E rationale: Oxygen saturation at 92% is relatively low. While the client is alert and oriented, a low oxygen saturation level may indicate potential respiratory compromise or inadequate oxygenation.
Choice F rationale: Temperature is not concerning because it is within normal range.
Choice G rationale: Neurological assessment is not concerning because the client is alert and oriented. The dizziness is likely related to the hypotension and will resolve once the blood pressure is stabilized.
Correct Answer is A
Explanation
Choice A rationale: Post-surgery, there's a risk of lymphedema in the affected arm, so avoiding procedures like venipuncture or blood pressure measurements in the left arm helps prevent complications.
Choice B rationale: Obtaining a permanent breast prosthesis is a consideration post- recovery but not an immediate priority upon return to the surgical unit.
Choice C rationale: Patient-controlled analgesia instructions are important but don't specifically address immediate care after mastectomy.
Choice D rationale: Insisting that the patient examine the surgical incision might not be appropriate upon return to the unit, and it's typically done by healthcare professionals during dressing changes.
