Correct Answer is D

Explanation

A. Injecting insulin at a 90-degree angle is a common technique for subcutaneous insulin injections.

B. Rotating injection sites is important to prevent lipodystrophy and ensure proper absorption.

C. Insulin should be injected into areas with adipose tissue, such as the abdomen, thighs, or buttocks.

D. Aspiration is not recommended before insulin injections. Aspiration may increase the risk of injecting the insulin into a blood vessel, leading to erratic absorption and potential
hypoglycemia. The current practice is to inject insulin subcutaneously without aspiration.

A. Administer at mealtimes. B. Administer at bedtime. C. Give with a 240 mL (8 oz) glass of milk. D. Give with orange juice.

Correct Answer is D

Explanation

A. Administer at mealtimes is incorrect. Taking iron supplements with food can decrease absorption. It is best to take them on an empty stomach if possible, but if gastrointestinal upset occurs, the medication can be taken with food.

B. Administer at bedtime is incorrect. Iron supplements are generally not recommended to be taken at bedtime due to potential gastrointestinal upset that might disturb sleep.

C. Give with a 240 mL (8 oz) glass of milk is incorrect. Milk can reduce the absorption of iron, so it is not recommended to take ferrous sulfate with milk.

D. Give with orange juice is correct. Vitamin C (found in orange juice) enhances the absorption of iron, so it is a good choice to help increase the effectiveness of the supplement.
