A nurse is reinforcing teaching with a client who has type 1 diabetes mellitus.
Which statement from the client indicates that the teaching is effective?

I will shake the insulin vial vigorously to mix.

I should inject the insulin into my abdominal area.

I should increase my insulin when I exercise.

I will freeze unopened insulin vials.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Shaking the insulin vial vigorously is not recommended. It can lead to the formation of bubbles, which can affect the accuracy of the dose. Instead, insulin vials should be gently rolled between the hands to mix.

Choice B rationale:

Injecting insulin into the abdominal area is indeed a recommended practice. The abdomen is a preferred site for insulin injection because it has a faster absorption rate compared to other areas. This can help to more effectively regulate blood glucose levels.

Choice C rationale:

Exercise typically lowers blood glucose levels, so insulin doses may need to be reduced to prevent hypoglycemia. Clients should monitor their blood glucose closely and adjust insulin as directed by their healthcare provider.

Choice D rationale:

Freezing unopened insulin vials is not advised. Freezing can disrupt the insulin structure, rendering it ineffective. Insulin should be stored in a refrigerator at a temperature between 2°C and 8°C (36°F and 46°F). Once opened, it can be kept at room temperature for up to 28 days.

Correct Answer is A

Explanation

Choice A rationale:

Rifampin Rifampin is an antitubercular drug that is effective against all strains of Mycobacterium tuberculosis. It works by inhibiting the synthesis of RNA in the bacteria, preventing them from reproducing. However, it does not typically cause a decrease in visual acuity.

Choice B rationale:

Ethambutol Ethambutol is an antitubercular drug that can cause ocular toxicity in the form of visual field changes. It is known to induce toxic optic neuropathy, which is quite common and can lead to a decrease in visual acuity. Patients on Ethambutol therapy are advised to report any changes in visual acuity or eye discomfort immediately to their healthcare provider.

Choice C rationale:

Streptomycin Streptomycin is an aminoglycoside antibiotic used in the treatment of tuberculosis. It works by inhibiting protein synthesis in bacteria. While it can cause side effects such as ototoxicity and nephrotoxicity, it is not typically associated with a decrease in visual acuity.

Choice D rationale:

Isoniazid Isoniazid is a first-line antitubercular drug that works by inhibiting the synthesis of mycolic acids in the cell wall of Mycobacterium tuberculosis. While it can cause peripheral neuropathy, it is not typically associated with a decrease in visual acuity.

A. Bone marrow suppression B. Retinitis C. Renal toxicity D. Hepatotoxicity

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.
