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 A
Explanation
Choice A: Observing the insertion site of the suprapubic catheter is an essential assessment for the home health nurse, as this can help detect any signs of infection, inflammation, or leakage. Therefore, this is the correct choice.
Choice B: Palpating the flank area is not a necessary assessment for the home health nurse, as this is not related to the suprapubic catheter. This is a distractor choice.
Choice C: Measuring abdominal girth is not a relevant assessment for the home health nurse, as this is not affected by the suprapubic catheter. This is another distractor choice.
Choice D: Assessing the perineal area is not an important assessment for the home health nurse, as this is not involved in the suprapubic catheter. This is another distractor choice.
Correct Answer is ["31.6"]
Explanation
The correct answer is : 31.6 mL
Let’s calculate this step by step:
Step 1: Convert 10 mg of teriparatide to mcg. We know that 1 mg = 1000 mcg. So, 10 mg = 10 × 1000 mcg = 10000 mcg.
Step 2: The medication is labeled as 760 mcg/2.4 ml. This means that 760 mcg of the medication is present in 2.4 mL.
Step 3: Now, we need to find out how many ml will contain 10000 mcg of the medication. We can set up a proportion to solve this:
(760 mcg / 2.4 ml) = (10000 mcg / x mL)
Step 4: Solving for x, we cross-multiply and divide:
x ml = (10000 mcg × 2.4 ml) ÷ 760 mcg
Step 5: Calculate the result:
x ml = 24000 mcg·ml ÷ 760 mcg = 31.57894736842105 mL
Step 6: If rounding is required, round to the nearest tenth:
x ml = 31.6 mL
So, the nurse should administer 31.6 mLof the medication.
