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

• A. platelet count
• B. prothrombin time (PT)
• C. partial thromboplastin time (PTT)
• D. D-dimer

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. Why is starting a low CHO diet a contraindication for a client with renal insufficiency?

• A. As long as the client eats a minimum of 30g of CHO/day, there should be no problem.
• B. The client's clinical condition is a contraindication to starting a low CHO diet.
• C. Calcium supplements should be utilized to prevent the development of osteoporosis while on a low CHO diet.
• D. As long as the client eats foods that are high biologic protein sources, a low CHO diet can be followed.

Correct answer: B

Rationale: A client with renal insufficiency should not start a low CHO diet because it could result in an increased renal solute load. Clients with renal or liver disease require protein control in their diet to prevent complications. Proteins used must be of high biologic value, and protein intake is usually weight-based. Protein levels may be adjusted based on the client's clinical condition. A minimum level of carbohydrates is needed in the diet to spare protein. Vitamin and mineral supplements might be needed for clients with liver failure. The dietician plays a crucial role in calculating specific nutrient requirements for these clients and monitoring outcomes in conjunction with the healthcare team. Choice A is incorrect because simply consuming a minimum amount of carbohydrates does not address the issue of increased renal solute load. Choice C is incorrect as calcium supplements are not the primary concern when considering a low CHO diet for a client with renal insufficiency. Choice D is incorrect as the focus should be on the contraindication of a low CHO diet for a client with renal insufficiency rather than just high biologic protein sources.

3. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

4. The client is preparing to learn about the effects of isoniazid (INH). Which information is essential for the client to understand?

• A. Isoniazid should be taken with meals to reduce gastrointestinal upset.
• B. Prolonged use of isoniazid may result in dark, concentrated urine.
• C. Taking aluminum hydroxide (Maalox) with isoniazid can enhance the drug's effects.
• D. Consuming alcohol daily can increase the risk of drug-induced hepatitis.

Correct answer: D

Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.

5. The nurse is caring for a client with full-thickness burns to the left arm and trunk. What is the priority for this client?

• A. Pain management
• B. Airway assessment
• C. Fluid volume status monitoring
• D. Risk for infection prevention

Correct answer: C

Rationale: Correct! With full-thickness burns, there is a significant risk of fluid loss through the burn wound and fluid shift, leading to hypovolemia and shock. Monitoring and maintaining the client's fluid volume status is crucial to prevent complications like hypovolemic shock. Pain management (Option A) is essential but not the priority in this situation. While airway assessment (Option B) is crucial, it is typically assessed first in clients with respiratory distress. Preventing infection (Option D) is important but managing fluid volume status takes precedence in the initial care of a client with full-thickness burns.
