A nurse is reinforcing teaching about insulin injections with a client who is newly diagnosed with type I diabetes mellitus.
Which of the following information should the nurse include about site selection?
Insulin is absorbed most rapidly when injected in the thigh.
Use cold insulin for injection to minimize site pain.
Massage the site after injection to promote absorption.
Rotate the injection site to keep insulin levels consistent.
The Correct Answer is D
Choice A rationale:
Insulin is not absorbed most rapidly when injected in the thigh. The abdomen is actually the preferred site for insulin injection as insulin is absorbed more quickly and predictably there. The thigh is a simple area for self-injection, but regular injections in the thigh can sometimes cause discomfort when walking or running afterward.
Choice B rationale:
Using cold insulin for injection to minimize site pain is not recommended. Insulin should be at room temperature. Cold insulin might make the injection more painful.
Choice C rationale:
Massaging the site after injection to promote absorption is not advised. It can cause the insulin to be absorbed too quickly which can lead to low blood glucose levels.
Choice D rationale:
Rotating the injection site to keep insulin levels consistent is the correct choice. People who take insulin daily should rotate their injection sites. This is important because using the same spot over time can cause lipodystrophy. In this condition, fat either breaks down or builds up under the skin, causing lumps or indentations that interfere with insulin absorption.

Correct Answer is C
No explanation
Correct Answer is A
Explanation
Choice A rationale:
Zidovudine, also known as AZT, is a medication used for the treatment of human immunodeficiency virus (HIV) infection. One of the major dose-limiting toxic effects of Zidovudine is hematologic toxicity, which manifests clinically as anemia, neutropenia, and sometimes as platelet deficits with onset after several weeks of treatment. This hematologic toxicity is essentially a form of bone marrow suppression. Therefore, bone marrow suppression is the dose-limiting adverse effect of zidovudine therapy.
Choice B rationale:
Retinitis is not a known dose-limiting adverse effect of zidovudine. While zidovudine has a range of side effects, retinitis is not commonly associated with its use.
Choice C rationale:
Renal toxicity is not a known dose-limiting adverse effect of zidovudine. While zidovudine can have various side effects, renal toxicity is not typically one of them.
Choice D rationale:
Hepatotoxicity is not the dose-limiting adverse effect of zidovudine. While severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of zidovudine, it is not considered the dose-limiting adverse effect. The dose-limiting adverse effect is more specifically related to hematologic toxicity, which includes bone marrow suppression.
