1. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?

Correct answer: D

Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.

2. What is most important for the healthcare professional to do prior to initiating peritoneal dialysis?

Correct answer: D

Rationale: The correct answer is to warm the fluids. Warming the dialysis fluids is crucial before initiating peritoneal dialysis to prevent abdominal discomfort and promote vasodilation, which helps in achieving good exchange in the peritoneum. Aspirating to check placement (Choice A) is not typically necessary before initiating peritoneal dialysis. Ensuring the client voids (Choice B) is not directly related to the procedure of peritoneal dialysis. Irrigating the catheter to maintain patency (Choice C) is usually done as part of routine care but is not specifically required prior to initiating peritoneal dialysis. Therefore, the most important action to take before starting peritoneal dialysis is to warm the fluids.

3. Which of the following statements should the nurse use to best describe a very low-calorie diet (VLCD) to a client?

Correct answer: A

Rationale: The correct answer is, "This diet can be used when there is close medical supervision."? Very low-calorie diets (VLCDs) are used in the clinical treatment of obesity under close medical supervision. The diet is low in calories, high in quality protein, and has a minimum of carbohydrates to spare protein and prevent ketosis. Choice B is incorrect because VLCDs are typically short-term interventions. Choice C is incorrect because VLCDs usually consist of nutritionally complete liquid formulations, not solid food items that are pureed. Choice D is incorrect because VLCDs actually contain a high quality of protein, although the overall caloric content is very low.

4. Why must the nurse be careful not to cut through or disrupt any tears, holes, bloodstains, or dirt present on the clothing of a client who has experienced trauma?

Correct answer: C

Rationale: The correct answer is C. Trauma in any client, living or dead, has potential legal and/or forensic implications. Clothing, patterns of stains, and debris are sources of potential evidence and must be preserved. Nurses must be aware of state and local regulations that require mandatory reporting of cases of suspected child and elder abuse, accidental death, and suicide. Each Emergency Department has written policies and procedures to assist nurses and other health care providers in making appropriate reports. Physical evidence is real, tangible, or latent matter that can be visualized, measured, or analyzed. Emergency Department nurses can be called on to collect evidence. Health care facilities have policies governing the collection of forensic evidence. The chain of evidence custody must be followed to ensure the integrity and credibility of the evidence. The chain of evidence custody is the pathway that evidence follows from the time it is collected until it has served its purpose in the legal investigation of an incident. Choices A, B, and D are incorrect because they do not address the crucial aspect of preserving potential evidence with legal implications that may be present on the clothing of a trauma victim.

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

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.
