Nursing Elites

1. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be monitored closely?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.5 mEq/L
• C. Serum creatinine of 1.8 mg/dl
• D. Serum glucose of 200 mg/dl

Correct answer: C

Rationale: In a client with left-sided heart failure, monitoring serum creatinine is crucial to evaluate kidney function and fluid balance. Elevated creatinine levels can indicate impaired kidney function, which is common in heart failure due to decreased cardiac output and renal perfusion. Serum sodium levels (choice A) are important but are more closely associated with fluid balance and heart failure exacerbation. Serum potassium (choice B) is also important to monitor, but it is more closely linked to cardiac arrhythmias rather than kidney function. Serum glucose levels (choice D) are significant but are not the priority for monitoring in left-sided heart failure.

2. Which instruction is most important for a client who receives a new plan of care to treat osteoporosis?

• A. Start a weight-bearing exercise plan.
• B. Increase consumption of foods rich in calcium.
• C. Arrange a bone density test every year.
• D. Stay upright after taking the medication.

Correct answer: D

Rationale: The correct answer is D: 'Stay upright after taking the medication.' This instruction is crucial for clients receiving medications like bisphosphonates to prevent esophageal irritation or erosion. While weight-bearing exercises (choice A) are important for bone health, staying upright after medication intake takes precedence. Increasing calcium-rich foods (choice B) is beneficial but not the most important immediate instruction. Scheduling bone density tests (choice C) is necessary for monitoring osteoporosis but is not as critical as staying upright after medication.

3. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

4. A client with a history of hypertension 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. Pulmonary function tests (PFTs)
• D. Arterial blood gases (ABGs)

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.

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.
