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. A client who is a Jehovah's Witness is admitted to the nursing unit. Which concern should the nurse have for planning care in terms of the client's beliefs?

• A. Autopsy of the body is prohibited.
• B. Blood transfusions are forbidden.
• C. Alcohol use in any form is not allowed.
• D. A vegetarian diet must be followed.

Correct answer: B

Rationale: The correct answer is B. In the Jehovah's Witness religion, blood transfusions are forbidden due to their beliefs. Autopsy prohibition is in Judaism, while alcohol and drug use is not allowed in Buddhism. While some sects are vegetarian, the critical concern in nursing care for Jehovah's Witnesses is respecting their prohibition of blood transfusions.

3. UAP has lowered the head of the bed to change the linens for a client who is bedbound with a foley catheter and enteral tube feeds. Which change from the client warrants the most immediate intervention by the nurse?

• A. A feeding is infusing at 40 mL/hr through an enteral feeding tube
• B. The urine meter attached to the urinary drainage bag is completely full
• C. There is a large dependent loop in the client’s urinary drainage tubing
• D. Purulent drainage is present around the insertion site of the feeding tube

Correct answer: D

Rationale: Purulent drainage indicates infection at the insertion site, which requires immediate attention to prevent complications.

4. How many drops per minute should a client weighing 182 pounds receive if a nurse mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min? The drip factor is 60 gtt/ml.

• A. 31 gtt/min.
• B. 62 gtt/min.
• C. 93 gtt/min.
• D. 124 gtt/min.

Correct answer: D

Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min × 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml × 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.

5. When assessing for orthostatic hypotension during blood pressure measurement, what action should the nurse implement first?

• A. Position the client supine for a few minutes
• B. Assist the client to stand at the bedside
• C. Apply the blood pressure cuff securely
• D. Record the client’s pulse rate and rhythm

Correct answer: A

Rationale: When assessing for orthostatic hypotension, the initial step is to position the client supine for a few minutes. This allows the body to adjust to the supine position before assessing blood pressure changes that may indicate orthostatic hypotension. By observing the blood pressure after the client has rested supine, the nurse can accurately assess for any drop in blood pressure upon standing, which is indicative of orthostatic hypotension. Choices B, C, and D are incorrect as they do not address the initial step in assessing for orthostatic hypotension, which is ensuring the client is positioned correctly to detect blood pressure changes upon standing.
