Nursing Elites

1. When assessing a client receiving total parenteral nutrition (TPN), which laboratory value is most important for the nurse to monitor regularly?

• A. Albumin
• B. Calcium
• C. Glucose
• D. Alkaline phosphatase

Correct answer: C

Rationale: The most important laboratory value to monitor regularly in clients receiving total parenteral nutrition (TPN) is glucose. TPN solutions contain high concentrations of glucose, which can lead to hyperglycemia. Monitoring glucose levels is crucial to detect and prevent hyperglycemia, a common complication associated with TPN administration. Albumin (Choice A) levels are not typically affected by TPN administration. Calcium (Choice B) and alkaline phosphatase (Choice D) are not directly impacted by TPN and are not the primary values to monitor in TPN therapy.

2. When preparing to administer medication to a client, what action should the nurse take first?

• A. Verify the client's identity.
• B. Check the medication expiration date.
• C. Review the client's medical history.
• D. Obtain the client's vital signs.

Correct answer: A

Rationale: Verifying the client's identity is the initial and most critical step in medication administration. It is crucial to confirm that the right medication is being given to the correct patient. Checking the client's identity helps prevent medication errors and ensures patient safety. Checking the medication expiration date (choice B) is important but should come after verifying the client's identity. Reviewing the client's medical history (choice C) is valuable but not the first step in medication administration. Obtaining the client's vital signs (choice D) is essential in some situations but is usually not the first action needed before administering medication.

3. The client is scheduled to undergo a treadmill stress test. Which instruction should the client be reinforced with?

• A. Eat a light meal before the test.
• B. Wear comfortable shoes and clothing.
• C. Avoid all physical activity the morning of the test.
• D. Take prescribed medications right before the test.

Correct answer: B

Rationale: The correct answer is B: 'Wear comfortable shoes and clothing.' Wearing comfortable shoes and clothing is crucial for the client undergoing a treadmill stress test to ensure they can complete the test without discomfort. The right attire will help the client move freely and reduce the risk of any hindrance during the test, which requires physical activity. Choices A, C, and D are incorrect. A light meal before the test may be recommended, but it's not as crucial as wearing suitable attire. Avoiding physical activity the morning of the test is not necessary as the test requires physical activity. Taking prescribed medications right before the test instructions should be followed as per the healthcare provider's advice and not as a general rule for all clients undergoing the test.

4. The LPN/LVN is assisting in the care of a client with a diagnosis of heart failure who is receiving digoxin (Lanoxin). Which laboratory result should the nurse monitor closely?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum glucose

Correct answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure. Serum sodium, serum calcium, and serum glucose levels are also important laboratory values to monitor in clients with heart failure, but they are not directly associated with the risk of digoxin toxicity. Monitoring these values helps in assessing overall health status, fluid balance, and metabolic functions in the client.

5. A client diagnosed with thrombophlebitis 1 day ago suddenly complains of chest pain and shortness of breath. The LPN/LVN understands that a life-threatening complication of this condition is which?

• A. Pneumonia
• B. Pulmonary edema
• C. Pulmonary embolism
• D. Myocardial infarction

Correct answer: C

Rationale: The correct answer is C, Pulmonary embolism. Pulmonary embolism is a critical complication of thrombophlebitis where a blood clot dislodges and travels to the lungs, obstructing blood flow. This obstruction can lead to chest pain, shortness of breath, and potentially fatal consequences, making it a life-threatening emergency that requires prompt intervention. Choices A, B, and D are incorrect because pneumonia, pulmonary edema, and myocardial infarction are not directly associated with thrombophlebitis and would not present with the sudden onset of chest pain and shortness of breath in this context.
