Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. When assessing constipation in elders, what action should be the nurse's priority?

• A. Obtain a complete blood count
• B. Obtain a health and dietary history
• C. Refer to a provider for a physical examination
• D. Measure height and weight

Correct answer: B

Rationale: Obtaining a detailed health and dietary history is crucial when assessing constipation in elders. This helps the nurse identify potential causes such as inadequate fluid intake, low fiber diet, lack of physical activity, or medications that could be contributing to constipation. A complete blood count (Choice A) is not the priority in the initial assessment of constipation. Referring to a provider for a physical examination (Choice C) would be done after gathering more information from the health history. Measuring height and weight (Choice D) is not directly relevant to assessing constipation and identifying its causes.

3. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

4. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

5. The healthcare provider prescribes a sedative for a client with severe hypothyroidism. What is the best action for the nurse to take?

• A. Affirm the nurse's plan to review the prescription with the provider.
• B. Administer the sedative as prescribed.
• C. Advise the nurse to administer the medication as prescribed.
• D. Offer to administer the medication since the nurse is concerned.

Correct answer: A

Rationale: The correct answer is to affirm the nurse's plan to review the prescription with the provider. Sedatives can worsen symptoms of hypothyroidism, so it is crucial to ensure the safety of the prescribed medication. Administering the sedative without further consultation could lead to adverse effects. Simply advising the nurse to administer the medication without addressing the need for review is not the best course of action. Offering to administer the medication without proper assessment or consulting the provider is not appropriate and could potentially harm the client.
