Nursing Elites

1. When providing postmortem care to a client diagnosed with Methicillin-resistant Staphylococcus aureus (MRSA) who has passed away, what type of precautions is appropriate to use?

• A. Airborne precautions
• B. Droplet precautions
• C. Contact precautions
• D. Compromised host precautions

Correct answer: C

Rationale: Contact precautions are the appropriate type to use when performing postmortem care for a client with MRSA. MRSA is primarily spread through direct contact, so using contact precautions helps prevent the transmission of the infection. Airborne precautions are not necessary for MRSA, as it is not transmitted through the air like tuberculosis or measles. Droplet precautions are used for diseases transmitted through respiratory droplets like influenza. Compromised host precautions are not a standard precaution type and are not specific to managing MRSA infection.

2. 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.

3. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

4. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

• A. 13 ml/hour
• B. 63 ml/hour
• C. 80 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

5. A client is postoperative following knee arthroplasty and requires the use of a thigh-length sequential compression device. Which of the following actions should the nurse take?

• A. Ensure two fingers can fit under the sleeves.
• B. Ensure the device is not too tight to impede circulation.
• C. Position the client comfortably before applying the device.
• D. Use the device continuously to prevent blood clots.

Correct answer: A

Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.
