Nursing Elites

1. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

2. The nurse is teaching a community health class for cancer prevention and screening. Which individual has the highest risk for colon cancer?

• A. Client with irritable bowel syndrome
• B. Family history of colon polyps
• C. Client with cirrhosis of the liver
• D. History of colon surgery

Correct answer: B

Rationale: A family history of colon polyps and/or colon cancer is a significant risk factor for developing colon cancer. Individuals with a family history are more likely to develop colon cancer due to genetic predisposition. While other factors like irritable bowel syndrome, cirrhosis of the liver, and history of colon surgery may contribute to an increased risk of colon cancer, having a family history of colon polyps is the highest risk factor. Irritable bowel syndrome does not directly increase the risk of colon cancer. Cirrhosis of the liver is associated with liver cancer rather than colon cancer. A history of colon surgery may reduce the risk of colon cancer in some cases by removing precancerous polyps.

3. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

• A. triglyceride level
• B. liver function tests
• C. a glucose tolerance test
• D. a complete blood count

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.

4. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?

• A. open leg fracture
• B. open head injury
• C. stab wound to the chest
• D. traumatic amputation of a thumb

Correct answer: C

Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.

5. Which of the following is an inappropriate item to include in planning care for a severely neutropenic client?

• A. Transfuse neutrophils (granulocytes) to prevent infection.
• B. Exclude raw vegetables from the diet.
• C. Avoid administering rectal suppositories.
• D. Prohibit vases of fresh flowers and plants in the client's room.

Correct answer: A

Rationale: Transfusing neutrophils (granulocytes) to prevent infection is inappropriate in the care of a severely neutropenic client. Neutrophils normally comprise 70% of all white blood cells and can be beneficial in a selected population of infected, severely granulocytopenic clients (less than 500/mm3) who do not respond to antibiotic therapy and who are expected to experience prolonged suppression of granulocyte production. Therefore, transfusing neutrophils is not a standard practice in caring for neutropenic clients. The other choices are appropriate in caring for a severely neutropenic client: excluding raw vegetables from the diet to reduce the risk of infections from potential pathogens, avoiding administering rectal suppositories to prevent any injury or infection due to mucosal damage, and prohibiting vases of fresh flowers and plants in the client's room to minimize the risk of exposure to environmental pathogens.
