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. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

3. While assessing a client who is admitted with heart failure and pulmonary edema, the nurse identifies dependent peripheral edema, an irregular heart rate, and a persistent cough that produces pink blood-tinged sputum. After initiating continuous telemetry and positioning the client, which intervention should the nurse implement?

• A. Administer prescribed diuretics
• B. Prepare for intubation
• C. Notify the healthcare provider immediately
• D. Obtain sputum sample

Correct answer: D

Rationale: The client's cough producing pink, frothy sputum is indicative of pulmonary edema, which needs immediate treatment. Obtaining a sputum sample helps identify any infection that may be contributing to the pulmonary issues. Administering diuretics is essential in managing pulmonary edema but obtaining a sputum sample should take priority. Intubation may be necessary in severe cases but is not the initial intervention. Notifying the healthcare provider is important, but immediate action to diagnose and treat the condition is crucial.

4. A client tells the nurse about working out with a personal trainer and swimming three times a week in an effort to lose weight and sleep better. The client states that it still takes hours to fall asleep at night. Which action should the nurse implement?

• A. Advise the client to reduce exercise intensity
• B. Ask the client for a description of the exercise schedule that is being followed
• C. Encourage the client to try relaxation techniques before bed
• D. Suggest avoiding water-based exercise before bed

Correct answer: B

Rationale: Asking the client for a description of the exercise schedule being followed is the most appropriate action for the nurse to take in this scenario. Understanding the timing and intensity of the client's exercise routine can help identify if the activity is contributing to sleep disturbances. Exercise too close to bedtime can cause difficulty falling asleep. Choices A, C, and D do not directly address the need to assess the exercise schedule and may not provide the necessary information to identify the potential cause of the client's sleep issue.

5. 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.
