Hemodynamic monitoring by means of a multilumen pulmonary artery catheter can provide detailed information about:
- A. Preload
- B. Afterload
- C. Cardiac output
- D. All of the above
Correct Answer: D
Rationale: A multilumen pulmonary artery catheter, also known as a Swan-Ganz catheter, is used for advanced hemodynamic monitoring. It is inserted through a central line and positioned in the pulmonary artery to provide detailed information about various hemodynamic parameters including preload, afterload, and cardiac output.

a hospitalized child with nephrosis is receiving high doses of prednisone. which of the following is an appropriate nursing goal related to this?
- A. prevent infection.
- B. stimulate appetite.
- C. detect evidence of edema.
- D. assist in raising osmotic pressure.
Correct Answer: A
Rationale: High doses of prednisone suppress the immune system, putting the hospitalized child at an increased risk for infections. Therefore, an appropriate nursing goal related to this situation would be to prevent infection by implementing measures such as hand hygiene, maintaining a clean environment, and monitoring for signs and symptoms of infection. It is crucial to protect the child from acquiring additional illnesses while undergoing treatment for nephrosis.
At the present time, the best treatment for cancer is complete __________ before metastasis occurs:
- A. Chemotherapy
- B. Radiation
- C. Surgical removal
- D. All of the above
Correct Answer: C
Rationale: The best treatment for cancer at the present time is complete surgical removal before metastasis occurs. Surgery is often the most effective method to remove the primary tumor and eliminate cancer cells in the affected area. While chemotherapy and radiation therapy are important in treating cancer, surgical removal of the tumor provides the best chance for complete eradication of cancer cells, especially if it is done before the cancer has spread to other parts of the body.
During chemotherapy, an oncology client has a nursing diagnosis of impaired oral mucous membrane related to decreased nutrition and immunosuppression secondary to the cytotoxic effects of chemotherapy. Which nursing intervention is most likely to decrease the pain of stomatitis?
- A. Recommending that the client discontinue chemotherapy
- B. Providing a solution of hydrogen peroxide and water for use as a mouth rinse
- C. monitoring the client's platelet and leukocyte counts
- D. Checking regularly for signs and symptoms of stomatitis
Correct Answer: B
Rationale: Providing a solution of hydrogen peroxide and water for use as a mouth rinse is most likely to decrease the pain of stomatitis. Stomatitis is inflammation of the oral mucous membranes and can be quite painful for oncology clients undergoing chemotherapy. Using a solution of hydrogen peroxide and water as a mouth rinse can help reduce the risk of infection and promote healing of the mucous membranes, thereby decreasing the pain associated with stomatitis. This intervention helps to maintain oral hygiene and prevent further complications, making it an effective way to manage the client's symptoms while undergoing chemotherapy. It is important to note that discontinuing chemotherapy would not be a recommended intervention as it is the primary treatment for the client's cancer. Monitoring platelet and leukocyte counts and checking for signs and symptoms of stomatitis are important aspects of care, but providing a mouth rinse would directly address the pain and discomfort experienced by the client.
After a 3- month trail of dietary therapy, a client with type2 diabetes mellitus still has blood glucose levels above 180 mg/dl. The physician adds glyburide (DiaBeta), 2.5 mg P.O. daily, to the treatment regimen. The nurse should instruct the client to take glyburide:
- A. 30 minutes before breakfast
- B. 30 minutes after dinner.
- C. in the midmorning
- D. at bedtime.
Correct Answer: D
Rationale: Glyburide (DiaBeta) is a sulfonylurea medication used to treat type 2 diabetes mellitus by stimulating the pancreas to release more insulin. Taking glyburide at bedtime is recommended because it helps to ensure that the medication's peak action aligns with the natural rise in blood glucose levels in the early morning hours, which can help control fasting blood glucose levels. Additionally, taking glyburide in the evening reduces the risk of hypoglycemia during the day when the client may be more active and less likely to monitor blood glucose levels closely.
