Nursing Elites

1. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

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

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

Correct answer: C

Rationale: In a client with left-sided heart failure, crackles in the lungs are a critical assessment finding that necessitates immediate intervention. Crackles indicate pulmonary congestion, a sign of worsening heart failure that requires prompt attention to prevent respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure, but crackles specifically point to pulmonary involvement and the urgent need for intervention.

3. The nurse is caring for a client with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 28 breaths per minute
• C. Tidal volume of 300 ml
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.

4. A male client with impaired renal function who takes ibuprofen daily for chronic arthritis is admitted with gastrointestinal (GI) bleeding. After administering IV fluids and a blood transfusion, his blood pressure is 100/70, and his renal output is 20 ml/hour. Which intervention should the nurse include in care?

• A. Maintain the client NPO during the diuresis phase.
• B. Evaluate daily serial renal laboratory studies for progressive elevations.
• C. Observe the urine character for sedimentation and cloudy appearance.
• D. Monitor for onset of polyuria greater than 150ml/hour.

Correct answer: B

Rationale: Evaluating daily renal laboratory studies is crucial in this scenario. The client has impaired renal function, recent GI bleeding, and is at risk for further kidney damage due to ibuprofen use. Monitoring renal labs helps assess kidney function and detect any progressive elevations, guiding further interventions. Option A is not directly related to renal function monitoring. Option C focuses more on urine appearance than renal function assessment. Option D mentions polyuria, which is excessive urine output, but the question describes a client with reduced renal output.

5. A client with hyperthyroidism who has not been responsive to medications is admitted for evaluation. What action should the nurse implement?

• A. Notify the healthcare provider.
• B. Review the client's medication history.
• C. Prepare the client for thyroid function tests.
• D. Initiate seizure precautions.

Correct answer: A

Rationale: In a scenario where a client with hyperthyroidism is not responding to medications, the nurse's priority action should be to notify the healthcare provider. This is important because the client may require immediate intervention, such as adjusting the treatment plan or exploring alternative therapies. Reviewing the client's medication history (choice B) may be relevant but not as urgent as involving the healthcare provider. While preparing the client for thyroid function tests (choice C) may be necessary as part of the evaluation process, it is not the most immediate action to take. Initiating seizure precautions (choice D) is not directly related to the non-responsiveness of medications in hyperthyroidism and is not a priority in this situation.
