A nurse is evaluating a client's laboratory results.
The nurse should recognize that an increase in the client's prostate specific antigen (PSA) laboratory value is indicative of which of the following diagnoses?
Liver cancer.
Breast cancer.
Colon cancer.
Prostatic cancer.
The Correct Answer is D
Choice A rationale
Liver cancer is not associated with elevated prostate specific antigen (PSA) levels. PSA is a protein produced primarily by prostate cells, and its elevation is typically linked to prostate-related conditions rather than liver disorders.
Choice B rationale
Breast cancer is not associated with elevated PSA levels. PSA is specific to prostate cells, which are not present in breast tissue. Therefore, PSA is not a marker used in diagnosing or monitoring breast cancer.
Choice C rationale
Colon cancer is not linked to elevated PSA levels. PSA is not a biomarker for colon cancer, as it is specific to the prostate gland. Other markers, such as carcinoembryonic antigen (CEA), are more relevant for colon cancer.
Choice D rationale
Prostatic cancer is associated with elevated PSA levels. PSA is produced by prostate cells, and elevated levels can indicate prostate cancer, benign prostatic hyperplasia (BPH), or inflammation of the prostate.

Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Resistance to the flow of IV fluid may indicate infiltration or extravasation, where the medication leaks into surrounding tissues, necessitating stopping the infusion.
Choice B rationale
Burning or pain, swelling, or redness at the site are signs of extravasation, which is a serious complication of vincristine administration and requires immediate action.
Choice C rationale
Reporting anxiety and depression are not directly related to vincristine infusion site complications. These are more systemic effects and do not indicate the need to stop the infusion immediately.
Choice D rationale
Nausea and vomiting are common side effects of vincristine but do not indicate a problem with the IV line itself, so they do not require stopping the infusion.
Choice E rationale
Absence of blood return from the IV catheter may indicate that the catheter is not in the vein properly, which requires stopping the infusion to prevent tissue damage.
Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Administering IV opioids can help manage the intense pain associated with frostbite, improving patient comfort during rewarming and recovery.
Choice B rationale
After rewarming, the extremity should be elevated, not lowered, to reduce edema by encouraging fluid return to the central circulation.
Choice C rationale
Immersing hands and feet in warm water is a crucial step in the rewarming process, which helps restore blood flow and prevent further tissue damage.
Choice D rationale
Elevating affected limbs after rewarming helps reduce edema and prevents further swelling and complications.
Choice E rationale
Tetanus prophylaxis is recommended in frostbite cases as frostbite injuries can break the skin, increasing the risk of tetanus infection. Hence, avoiding tetanus prophylaxis is incorrect.
