Nursing Elites

1. What are the final factors that contribute to blood pressure? (Select all that apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.

2. What is the most important action to prevent complications while caring for a client receiving enteral nutrition via a nasogastric tube?

• A. Check tube placement before each feeding
• B. Flush the tube with water before and after each feeding
• C. Elevate the head of the bed to 30 degrees
• D. Administer the feeding at room temperature

Correct answer: A

Rationale: Checking tube placement before each feeding is crucial to prevent aspiration, a serious complication of enteral nutrition. Ensuring the tube is correctly positioned in the stomach helps avoid the risk of the feeding going into the lungs, which can lead to aspiration pneumonia. Flushing the tube with water (Choice B) is important for maintaining tube patency but is not the most critical action to prevent complications. Elevating the head of the bed (Choice C) helps reduce the risk of aspiration but is not as crucial as verifying tube placement. Administering the feeding at room temperature (Choice D) is more related to patient comfort and does not directly address the prevention of complications associated with enteral nutrition via a nasogastric tube.

3. The nurse is assessing a client with a suspected diagnosis of deep vein thrombosis (DVT). Which clinical sign is most indicative of DVT?

• A. Redness and warmth over the affected area
• B. Decreased peripheral pulses
• C. Cyanosis of the toes
• D. Muscle cramps in the calf

Correct answer: A

Rationale: Corrected Rationale: Redness and warmth over the affected area are classic signs of inflammation, which commonly occur in deep vein thrombosis (DVT) due to the obstruction of blood flow. These symptoms result from the body's inflammatory response to the blood clot. Choices B, C, and D are less indicative of DVT. Decreased peripheral pulses may occur in arterial insufficiency rather than DVT. Cyanosis of the toes indicates decreased oxygenation and is more characteristic of arterial issues. Muscle cramps in the calf are nonspecific and can be caused by various conditions, not solely DVT.

4. Which client is at the highest risk for developing pressure ulcers?

• A. A 50-year-old client with a fractured femur
• B. A 30-year-old client with diabetes mellitus
• C. A 65-year-old client with limited mobility
• D. A 70-year-old client with a history of stroke

Correct answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.

5. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
