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.
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
To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.
30 lb / 2.205 = 13.61 kg.
Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.
Dose (in mcg) = 136.1 mcg.
Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.
1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.
Cross-multiplying, we get:. 1X = 136.1 x 1.
X = 136.1 mL.
Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
Correct Answer is C
Explanation
We can use the following formula to calculate the infusion rate:
Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg
First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg
125,000 mcg/500 mL = 250 mcg/mL
Now we can plug in the values we have into the formula:
Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr
Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.
Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.
