Nursing Elites

1. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

2. The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Prothrombin time (PT)
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.

3. The nurse and an unlicensed assistive personnel (UAP) are providing care for a client with a nasogastric tube (NGT) when the client begins to vomit. How should the nurse manage this situation?

• A. Direct the UAP to measure the emesis while the nurse irrigates the NGT
• B. Stop the NGT feed and notify the healthcare provider
• C. Increase the NGT suction pressure
• D. Elevate the head of the bed

Correct answer: A

Rationale: During vomiting in a client with an NGT, it is essential for the nurse to direct the UAP to measure the emesis to monitor the output. This helps in assessing the client's condition and response to treatment. Meanwhile, irrigating the NGT can be beneficial to relieve any obstruction that might be contributing to the vomiting. Stopping the NGT feed and notifying the healthcare provider (choice B) is important but not the immediate action needed. Increasing the NGT suction pressure (choice C) is unnecessary and can lead to complications. Elevating the head of the bed (choice D) is a general intervention to prevent aspiration but may not address the immediate issue of managing the vomiting episode and potential tube obstruction.

4. A client with a history of chronic heart failure is admitted with shortness of breath. Which laboratory value should be closely monitored?

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Hemoglobin level

Correct answer: B

Rationale: Corrected Rationale: In a client with chronic heart failure, serum potassium levels should be closely monitored to assess for hyperkalemia, which can worsen heart failure. Monitoring serum sodium levels is not the priority in this case. Serum creatinine level monitoring is more related to kidney function than heart failure. Hemoglobin levels are important but not the primary concern when assessing heart failure exacerbation.

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

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

Correct answer: C

Rationale: Corrected Rationale: In a client with left-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention to prevent worsening heart failure symptoms and respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure but are not as critical as crackles in the lungs because they may indicate fluid overload or right-sided heart failure, which are important to address but not as urgently as managing pulmonary congestion.
