Why is subcutaneous (SC) insulin usually administered into the abdomen as the preferred site?

It is the least painful location for this injection.

It causes less bruising at the site.

There are fewer insulin side effects when given in this site.

There is steady absorption of insulin from this site.

Answer and Explanation

The Correct Answer is D

According to the web, the abdomen is the preferred site for insulin injection because insulin is absorbed more quickly and predictably there.

This helps to maintain a stable blood glucose level and avoid hypoglycemia or hyperglycemia.

The other choices are not answers because:

Choice A (it is the least painful location for this injection) is incorrect because pain depends on various factors, such as needle size, injection technique, and individual sensitivity. The abdomen may not be the least painful location for everyone.

Choice B (it causes less bruising at the site) is incorrect because bruising can occur at any injection site if the needle damages a blood vessel. The abdomen does not have less blood vessels than other sites.

Choice C (there are fewer insulin side effects when given in this site) is incorrect because insulin side effects are not related to the injection site, but to the dose, type, and quality of insulin. The abdomen does not reduce the risk of side effects such as allergic reactions, weight gain, or low blood sugar.

Correct Answer is B

Explanation

We can use the following formula to calculate the infusion time:

Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)

First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:

19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:

Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours

To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:

9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)

Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).

A. 0.2 mL/min B. 0.4 mL/min C. 1 mL/min D. 2 mL/min E. 2 mL/min

Correct Answer is A

Explanation

The patient is ordered to receive 0.3 mg/kg of Nubain IV over 10 minutes. The patient weighs 148 lb, which is equivalent to 67.3 kg. To calculate the total amount of Nubain the patient should receive, multiply the weight by the dosage:

67.3 kg x 0.3 mg/kg = 20.19 mg

The Nubain is available in 10 mg/mL, which means there is 10 mg of Nubain in 1 mL of solution. To calculate how many milliliters of Nubain the patient should receive, divide the total amount of Nubain by the concentration:

20.19 mg / 10 mg per mL = 2.019 mL

To calculate how many milliliters per minute the nurse should administer, divide the total volume of Nubain by the infusion time:

2.019 mL / 10 minutes = 0.2019 mL per minute

Rounding to one decimal place, the nurse should administer 0.2 mL of Nubain per minute to the patient.
