Nursing Elites

1. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

2. A client who underwent preadmission testing 1 week before surgery had blood drawn for several serum laboratory studies. Which abnormal laboratory results should the nurse report to the surgeon’s office? Select all that apply.

• A. Hematocrit 30%
• B. Sodium 141 mEq/L
• C. Hemoglobin 8.9 g/dL
• D. Platelets 210,000 cells/mm3

Correct answer: C

Rationale: The correct answer is C. Hemoglobin level of 8.9 g/dL is below the normal range, indicating anemia. Anemia can affect the body's ability to carry oxygen, impacting surgical outcomes. Hematocrit level is an indirect measure of red blood cells, which also reveals anemia when low. Sodium level of 141 mEq/L and platelet count of 210,000 cells/mm3 are within normal ranges and do not require immediate reporting. Abnormal sodium levels can lead to various issues, but in this scenario, it is not a concern for surgical readiness. Platelet count is vital for blood clotting, and a count of 210,000 cells/mm3 is considered normal, so it does not need urgent attention.

3. The patient is receiving a high dose of intravenous azithromycin to treat an infection and taking acetaminophen for pain. The nurse should expect to review which lab values when monitoring for this drug’s side effects?

• A. Complete blood counts
• B. Electrolytes
• C. Liver enzymes
• D. Urinalysis

Correct answer: C

Rationale: When a patient is receiving a high dose of intravenous azithromycin, which is a macrolide antibiotic, in combination with acetaminophen, a potentially hepatotoxic drug, the nurse should monitor liver enzymes. High doses of macrolides when taken with hepatotoxic drugs like acetaminophen can lead to hepatotoxicity. Reviewing liver enzymes helps in early detection of liver damage. Complete blood counts (Choice A) are not typically affected by azithromycin or acetaminophen. Electrolytes (Choice B) are not directly impacted by these medications. Urinalysis (Choice D) is not specifically indicated for monitoring the side effects of azithromycin and acetaminophen combination therapy.

4. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)

• A. Man with prostate cancer
• B. Woman with blood clots in the urinary tract
• C. Client with ureterolithiasis
• D. All of the above

Correct answer: D

Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.

5. A healthcare professional reviews a client’s laboratory results. Which results from the client’s urinalysis should the healthcare professional identify as normal? (Select all that apply.)

• A. pH: 6
• B. Specific gravity: 1.015
• C. Glucose: negative
• D. All of the above

Correct answer: D

Rationale: In a urinalysis, a pH of 6 is within the normal range (typically between 4.6 and 8); a specific gravity of 1.015 is considered normal (usually ranging between 1.005 to 1.030); and a negative glucose result is also normal. Therefore, choices A, B, and C are correct as they fall within the normal values for a urinalysis. Choices A, B, and C are the correct answers, as the pH, specific gravity, and glucose levels are within the normal range for a urinalysis. Choice D is correct because all the listed values are normal. Choices A, B, and C are the correct options as they meet the criteria for normal urinalysis values. The other choices do not fall within the normal range for a urinalysis.
