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. A client with a diagnosis of tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?

• A. Avoid close contact with others until treatment is complete.
• B. Take all prescribed medications as directed.
• C. Schedule a follow-up appointment with the healthcare provider.
• D. Wear a mask when in public places.

Correct answer: B

Rationale: The most important instruction for a client with tuberculosis (TB) is to take all prescribed medications as directed. This is crucial to prevent the development of drug-resistant TB. While avoiding close contact with others until treatment is complete (Choice A) is important to prevent the spread of TB, ensuring the client completes the prescribed medication regimen is the priority. Scheduling a follow-up appointment (Choice C) is important for monitoring but not as critical as medication adherence. Wearing a mask in public places (Choice D) can help reduce the spread of TB but is not as essential as taking medications as prescribed.

3. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?

• A. Phenytoin level
• B. Sodium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

4. A client with cirrhosis is experiencing pruritus. Which intervention should the nurse include in the care plan?

• A. Administer antihistamines as prescribed
• B. Apply alcohol-based lotions to the skin
• C. Encourage frequent baths with hot water
• D. Limit fluid intake

Correct answer: A

Rationale: The correct answer is A: Administer antihistamines as prescribed. Pruritus, or itching, is a common symptom in clients with cirrhosis. Antihistamines can help relieve itching by blocking the effects of histamine. Applying alcohol-based lotions (choice B) can further dry out the skin and exacerbate itching. Encouraging frequent baths with hot water (choice C) can also worsen pruritus by stripping the skin of natural oils. Limiting fluid intake (choice D) is not directly related to managing pruritus in cirrhosis.

5. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
