Nursing Elites

1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Serum magnesium level

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.

2. The nurse is assessing a client with left-sided heart failure. Which finding requires immediate intervention?

• A. Shortness of breath
• B. Jugular venous distention
• C. Crackles in the lungs
• D. Peripheral edema

Correct answer: C

Rationale: Crackles in the lungs indicate pulmonary congestion in a client with left-sided heart failure and require immediate intervention to prevent respiratory failure. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potentially respiratory distress. Shortness of breath, jugular venous distention, and peripheral edema are common manifestations of heart failure but do not directly indicate acute respiratory compromise like crackles in the lungs do.

3. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?

• A. INR of 3.0
• B. Prothrombin time (PT) of 15 seconds
• C. Hemoglobin of 10 g/dl
• D. White blood cell count

Correct answer: A

Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.

4. The nurse is assessing a client with left-sided heart failure. Which finding is most concerning?

• A. Jugular venous distention
• B. Crackles in the lungs
• C. Shortness of breath
• D. Peripheral edema

Correct answer: C

Rationale: Shortness of breath is most concerning in a client with left-sided heart failure as it indicates pulmonary congestion, requiring immediate intervention. Jugular venous distention (Choice A) is a sign of increased central venous pressure but is not as concerning as pulmonary congestion. Crackles in the lungs (Choice B) are common in heart failure due to fluid accumulation but are not as immediately concerning as severe shortness of breath. Peripheral edema (Choice D) is a manifestation of fluid retention in the body but is less indicative of acute pulmonary distress compared to shortness of breath.

5. A 75-year-old female client is admitted to the orthopedic unit following an open reduction and internal fixation of a hip fracture. On the second postoperative day, the client becomes confused and repeatedly asks the nurse where she is. What information is most important for the nurse to obtain?

• A. History of alcohol use
• B. Current medication list
• C. Baseline cognitive status
• D. Family history of dementia

Correct answer: A

Rationale: The correct answer is A: History of alcohol use. In this scenario, obtaining the history of alcohol use is crucial as it could indicate withdrawal, which might explain the client's confusion. Alcohol withdrawal can lead to symptoms such as confusion, agitation, and disorientation. While knowing the current medication list (choice B) is important for overall patient care, in this case, alcohol withdrawal is a more likely cause of the confusion. Baseline cognitive status (choice C) is valuable for comparison but may not directly explain the sudden confusion. Family history of dementia (choice D) is less relevant in this acute situation compared to the potential immediate impact of alcohol withdrawal.
