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 B This situation could lead to conflict, but the client is not actively posing an immediate danger. The nurse should still intervene, but it is not the highest priority.
Choice A is incorrect because the client with anorexia nervosa who is refusing to eat the evening snack is not in immediate danger. The nurse should monitor the client's nutritional status and weight, but this can be done later.
Choice C iThe client with bipolar disorder who is pacing may be exhibiting signs of agitation, restlessness, or escalating mania, which can quickly lead to aggression, impulsivity, or loss of control. This behavior requires immediate attention to ensure safety for both the client and others on the unit. Manic or agitated patients may become unpredictable, making early intervention crucial.
Choice D is incorrect because the client with major depression who refuses to participate in group is not in immediate danger. The nurse should encourage the client to join the group, but this can be done later.
Correct Answer is C
Explanation
Choice A: Providing bedside equipment for transmission and protective precautions is not the first action that the nurse should implement, as this is a standard precaution that should be already in place for all clients in the critical care unit. This is a distractor choice.
Choice B: Evaluating daily serum electrolytes and hydration status is not the first action that the nurse should implement, as this is a routine assessment that can be done later after addressing the immediate problem of infection. This is another distractor choice.
Choice C: Culturing sputum, urine, burn wound, and all intravenous access sites is the first action that the nurse should implement, as this can help identify the source and type of infection, which can guide the appropriate antibiotic therapy and prevent further complications. Therefore, this is the correct choice.
Choice D: Implementing central line-associated bloodstream infection (CLABSI) protocols is not the first action that the nurse should implement, as this is a preventive measure that may not be applicable for this client who already has SIRS. This is another distractor choice.
