Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A nurse receives a report about a client who has 0.9% sodium chloride infusing IV at 125 mL/hr. When the nurse performs the initial assessment, they note that the client has received only 80 mL over the last 2 hrs. Which of the following actions should the nurse take first?

• A. Check the IV tubing for obstruction
• B. Increase the infusion rate
• C. Administer a bolus of fluid
• D. Replace the IV catheter

Correct answer: A

Rationale: The correct first action for the nurse to take in this situation is to check the IV tubing for obstruction. By doing this, the nurse can assess if there is any blockage or kink in the tubing that is impeding the flow of the IV solution. This step is crucial as it helps in identifying the reason for the inadequate infusion rate. Increasing the infusion rate (Choice B) without first checking for obstructions can lead to potential complications if there is a blockage. Administering a bolus of fluid (Choice C) may not be appropriate without addressing the cause of the decreased infusion rate. Similarly, replacing the IV catheter (Choice D) is not the initial priority unless obstruction is ruled out and other troubleshooting measures have been taken.

3. A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?

• A. Thermometer
• B. Elastic stockings
• C. Blood pressure cuff
• D. Sequential compression devices

Correct answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.

4. A cerebrovascular accident patient is placed on a ventilator. The client’s daughter arrives with a durable power of attorney and a living will that indicates no extraordinary life-saving measures. What action should the nurse take?

• A. Refer to the risk manager
• B. Notify the healthcare provider
• C. Discontinue the ventilator
• D. Review the medical record

Correct answer: B

Rationale: The correct action for the nurse to take is to notify the healthcare provider. In this situation, involving the healthcare provider ensures appropriate review and adherence to legal and ethical standards based on the living will and durable power of attorney. Referring to the risk manager may not be directly related to the immediate decision-making process regarding the ventilator. Discontinuing the ventilator without proper authorization from the healthcare provider could lead to legal and ethical implications. Reviewing the medical record alone may not provide guidance on how to proceed with the specific instructions from the living will and durable power of attorney.

5. A healthcare professional is preparing to transfer a client who can bear weight on one leg from the bed to a chair. After securing a safe environment, which of the following actions should the healthcare professional take next?

• A. Assess the client for orthostatic hypotension
• B. Obtain a gait belt
• C. Ensure the client has proper footwear
• D. Ask the client to perform range-of-motion exercises

Correct answer: A

Rationale: Assessing the client for orthostatic hypotension is the priority before transferring a client who can bear weight on one leg. This assessment helps identify the risk of dizziness or fainting when the client moves from a supine to an upright position. Obtaining a gait belt may be necessary for the transfer, but assessing for orthostatic hypotension comes first to ensure the safety of the client. Ensuring the client has proper footwear is important for preventing falls during ambulation but is not the immediate next step in this situation. Asking the client to perform range-of-motion exercises is not necessary before the transfer and does not address the immediate safety concern of orthostatic hypotension.
