Nursing Elites

1. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?

• A. Check for a blood return.
• B. Reposition the client's arm.
• C. Remove the IV site dressing.
• D. Flush the lock with saline.

Correct answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

2. The healthcare provider receives a report that a client with an indwelling urinary catheter has an output of 150 mL for the previous 6-hour shift. Which intervention should the healthcare provider implement first?

• A. Check the drainage tubing for a kink
• B. Review the intake and output record
• C. Notify the healthcare provider
• D. Give the client 8 oz of water to drink

Correct answer: A

Rationale: The first intervention should be to check the drainage tubing for a kink. This step is crucial as any kinks in the tubing could obstruct urine flow, leading to a decreased output. By ensuring the tubing is free from any obstructions, the healthcare provider can address a potential mechanical issue causing the low output before considering other interventions. Reviewing the intake and output record may provide valuable information but should come after ensuring the tubing is clear. Notifying the healthcare provider can be done later if needed, but the immediate concern is to check for any obstructions. Giving the client water to drink may be necessary depending on the assessment findings, but addressing a possible kink in the tubing takes precedence.

3. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

4. The healthcare provider obtains a BP reading of 100/88 in the right arm of a client whose blood pressure is typically 120/60 in the same arm. What action should the healthcare provider implement first?

• A. Use an electronic sphygmomanometer to take the BP every 30 minutes.
• B. Retake the blood pressure in the same arm, deflating the cuff slowly.
• C. Ask another healthcare provider to recheck the blood pressure to compare results.
• D. Obtain another blood pressure cuff and retake the blood pressure.

Correct answer: B

Rationale: The healthcare provider should first retake the blood pressure in the right arm, deflating the cuff slowly, because a low systolic and high diastolic blood pressure measurement is often the result of deflating the cuff too rapidly. Taking the BP in the same arm ensures consistency and accuracy of the measurement.

5. After surgery, a patient has decreased cardiac output. What is a likely observation by the nurse?

• A. Decreased urine output
• B. Increased urine output
• C. Flushing of the skin
• D. Hyperventilation

Correct answer: A

Rationale: A decrease in cardiac output can lead to decreased blood flow to the kidneys, resulting in decreased urine output. The kidneys rely on adequate blood supply to filter waste and produce urine. Therefore, a decreased urine output is a common observation when cardiac output is reduced. Choices B, C, and D are incorrect. Increased urine output is not typically associated with decreased cardiac output; flushing of the skin is more related to vasodilation, and hyperventilation is not directly linked to decreased cardiac output.
