Question 1 of 5
A client with B negative blood requires a blood transfusion during surgery. If no B negative blood is available, the client should be transfused with:
Correct Answer: C
Rationale: O negative blood is the universal donor type, safe for all recipients, including B negative, as it lacks A, B, and Rh antigens, minimizing transfusion reactions.
Question 2 of 5
The nurse should know that according to current thinking, the most important prognostic factor for a client with breast cancer is:
Correct Answer: B
Rationale: Although tumor size is a factor in classification of cancer growth, it is not an indicator of lymph node spread. Axillary node status is the most important indicator for predicting how far the cancer has spread. If the lymph nodes are positive for cancer cells, the prognosis is poorer. The client's previous history of cancer puts her at an increased risk for breast cancer recurrence, especially if the cancer occurred in the other breast. It does not predict prognosis, however. The estrogen-progesterone assay test is used to identify present tumors being fed from an estrogen site within the body. Some breast cancers grow rapidly as long as there is an estrogen supply such as from the ovaries. The estrogen-progesterone assay test does not indicate the prognosis.
Question 3 of 5
A client with Parkinson's disease is scheduled for stereotactic surgery. Which finding indicates that the surgery had its intended effect?
Correct Answer: A
Rationale: Stereotactic surgery, such as deep brain stimulation, aims to reduce symptoms like intractable tremors in Parkinson's disease. It does not directly increase dopamine or serotonin production, nor does it eliminate the need for medication entirely.
Question 4 of 5
A client with a history of liver failure is admitted with complaints of confusion. The nurse should expect the client to have:
Correct Answer: A
Rationale: Liver failure impairs ammonia detoxification, leading to hyperammonemia, which causes hepatic encephalopathy and confusion.
Question 5 of 5
The client is admitted with a diagnosis of gastroenteritis. Which precaution should the nurse implement?
Correct Answer: B
Rationale: Gastroenteritis is often caused by pathogens like norovirus, requiring contact precautions to prevent fecal-oral transmission. Standard precautions are insufficient, and droplet or airborne are not indicated.
