A nurse is preparing a 50 mL dose of 50% dextrose IV for a patient experiencing insulin shock. What is the best method for administering the medication?

Mix the dextrose in a 50 mL piggyback for a total volume of 100 mL.

Dilute the dextrose in one liter of 0.9% normal saline solution.

Ask the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution.

Push the undiluted dextrose slowly through the currently infusing IV.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the best method for administering the medication. This would dilute the dextrose, potentially reducing its effectiveness.
Choice B rationale
Diluting the dextrose in one liter of 0.9% normal saline solution is not the best method for administering the medication. This would significantly dilute the dextrose, potentially reducing its effectiveness.
Choice C rationale
Asking the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the best method for administering the medication. This would not provide the immediate glucose boost needed to counteract insulin shock.
Choice D rationale

Pushing the undiluted dextrose slowly through the currently infusing IV is the best method for administering the medication. This allows for rapid administration of a concentrated glucose solution, which is necessary to quickly raise blood glucose levels in a patient experiencing insulin shock.

Correct Answer is C

Explanation

Choice A rationale
While the sensitivity of genetic markers can influence the choice of treatment, it is not the primary pathophysiological process involved in BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify genetic mutations that increase the risk of developing certain types of cancer.
Choice B rationale
BRCA1 and BRCA2 do play a role in protecting mature, functioning breast and ovarian cells. However, this is not the primary reason for conducting BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify mutations that increase cancer risk.
Choice C rationale

This is the correct answer. Mutations in BRCA1 or BRCA2 can significantly increase a person’s risk for developing breast and ovarian cancer. Therefore, identifying these mutations through genetic testing can help determine a person’s cancer risk.
Choice D rationale
While inherited mutations in BRCA1 and BRCA2 can influence the prognosis of breast cancer, the primary purpose of BRCA1 and BRCA2 genetic testing is to identify mutations that increase cancer risk, not to determine prognosis.

A. Moon facies. B. Abdominal striae. C. Gastric irritation. D. Rapid weight gain.

Correct Answer is C

Explanation

Choice A rationale
Moon facies, characterized by a round face, is a side effect of long-term use of prednisone. However, it is not the most important symptom for the client to report to the healthcare provider in this context.
Choice B rationale
Abdominal striae, or stretch marks on the abdomen, can also be a side effect of long-term use of prednisone. While it may be a concern for some patients due to cosmetic reasons, it is not the most critical symptom to report in this case.
Choice C rationale
Gastric irritation is a common side effect of prednisone and can lead to more serious complications such as gastric ulcers if not addressed promptly. Therefore, it is the most important symptom for the client to report to the healthcare provider.
Choice D rationale
Rapid weight gain can be a side effect of prednisone use. While it is important to monitor weight while on this medication, it is not the most critical symptom to report in comparison to gastric irritation.
