Nursing Elites

1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

2. A 65-year-old male client with a history of smoking and high cholesterol is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Pulmonary function tests (PFTs)

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia, especially given the client's symptoms and history. Chest X-ray (Choice B) may be ordered to evaluate the lungs but would not be the initial test for this client presenting with chest pain and shortness of breath. Arterial blood gases (ABGs) (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for a client with suspected cardiac issues. Pulmonary function tests (PFTs) (Choice D) are used to assess lung function and would not be the first test indicated in this scenario.

3. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Blood urea nitrogen (BUN)
• C. Serum creatinine
• D. Serum glucose

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?

• A. Use of accessory muscles
• B. Oxygen saturation of 94%
• C. Carbon dioxide level of 45 mmHg
• D. Respiratory rate of 20 breaths per minute

Correct answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

5. A female client with type 2 diabetes reports that she has been taking her medications as prescribed but her blood glucose levels remain elevated. Which action should the nurse take first?

• A. Check the client's current blood glucose level.
• B. Assess the client's diet and medication adherence.
• C. Review the client's medication list for potential interactions.
• D. Obtain a hemoglobin A1c level.

Correct answer: C

Rationale: The correct action the nurse should take first is to review the client's medication list for potential interactions. This step is crucial as it can help identify any medications that might be contributing to the elevated blood glucose levels. Checking the current blood glucose level (choice A) is important but not the first action to address the ongoing issue. Assessing the client's diet and medication adherence (choice B) is also important, but reviewing the medication list should be the initial step to rule out any drug-related causes. Obtaining a hemoglobin A1c level (choice D) is a valuable assessment but may not address the immediate need to identify potential medication interactions.
