Nursing Elites

1. 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.

2. When making the bed of a client who needs a bed cradle, which action should the nurse include?

• A. Teach the client to call for help before getting out of bed.
• B. Keep both the upper and lower side rails in a raised position.
• C. Keep the bed in the lowest position while changing the sheets.
• D. Drape the top sheet and covers loosely over the bed cradle.

Correct answer: D

Rationale: A bed cradle is used to keep the top bedclothes off the client, so the nurse should drape the top sheet and covers loosely over the cradle. This helps in maintaining the proper positioning and function of the bed cradle to ensure the client's comfort and safety during bed making.

3. You are assigned to teach a student how to suction an adult patient with a tracheostomy. Which of the following actions by the student would be incorrect?

• A. Pre-oxygenating the patient with a Resuscibag at 100% O2 several times before suctioning.
• B. Maintaining wall suction pressure at 110-150 mmHg.
• C. Not suctioning for greater than 10-15 seconds at a time.
• D. Applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning.

Correct answer: D

Rationale: The incorrect action by the student is applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning. This technique can cause trauma to the tracheal walls, increasing the risk of injury to the patient. It is essential to perform suctioning gently and without rotation to prevent complications in patients with a tracheostomy. Pre-oxygenating the patient, maintaining appropriate suction pressure, and limiting suctioning time are all correct actions when suctioning a patient with a tracheostomy.

4. When turning an immobile bedridden client without assistance, which action best ensures client safety?

• A. Securely grasp the client's arm and leg.
• B. Put bed rails up on the side of bed opposite from the nurse.
• C. Correctly position and use a turn sheet.
• D. Lower the head of the client's bed slowly.

Correct answer: B

Rationale: The correct answer is to put bed rails up on the side of the bed opposite from the nurse. This action is essential to prevent the client from falling out of bed during the turning process. Since the nurse can only stand on one side of the bed, having the bed rails up on the opposite side provides an additional safety measure. Securing the client's arm and leg or lowering the head of the bed would not prevent the client from falling and may pose a risk of injury. Using a turn sheet correctly can be helpful, but ensuring the bed rails are up is a more direct safety measure in this situation.

5. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.
