Nursing Elites

1. Which lab test is used to assess renal function?

• A. Check blood glucose levels
• B. Monitor serum creatinine
• C. Monitor BUN
• D. Check electrolyte levels

Correct answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

2. A nurse is providing discharge instructions to a client with chronic obstructive pulmonary disease (COPD) who is prescribed home oxygen. Which of the following statements should the nurse make?

• A. Check your oxygen equipment daily for proper function.
• B. Increase the oxygen flow rate if you feel short of breath.
• C. Store your oxygen tanks lying flat on the floor.
• D. It is safe to smoke as long as you are more than 10 feet from the oxygen source.

Correct answer: A

Rationale: The correct statement for the nurse to make is to advise the client to check the oxygen equipment daily for proper function. This is crucial to ensure the client's home oxygen therapy is working effectively and safely. Choice B is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored upright, not lying flat. Choice D is incorrect and unsafe advice, as smoking near an oxygen source can lead to a fire hazard.

3. A nurse is reviewing the laboratory report of a client who has been taking lithium carbonate for the past 12 months. The nurse notes a lithium level of 0.8 mEq/L. Which of the following orders from the provider should the nurse expect?

• A. Withhold the next dose
• B. Increase the dosage
• C. Discontinue the medication
• D. Administer the medication

Correct answer: D

Rationale: The correct answer is to administer the medication (Choice D) since the lithium level of 0.8 mEq/L falls within the therapeutic range of 0.6-1.2 mEq/L. Withholding the next dose (Choice A) or increasing the dosage (Choice B) is not necessary as the current level is appropriate. Discontinuing the medication (Choice C) is not warranted based on the given lithium level. It is crucial to maintain therapeutic levels to ensure the medication's effectiveness without causing toxicity.

4. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.

5. A nurse is preparing to administer an IV bolus of 0.9% sodium chloride to a client who is dehydrated. Which of the following actions should the nurse take?

• A. Administer the solution slowly over 24 hours
• B. Assess the client's lung sounds before administration
• C. Change the IV tubing every 12 hours
• D. Flush the IV line with 2 mL of heparin every 4 hours

Correct answer: B

Rationale: The correct action for the nurse to take is to assess the client's lung sounds before administering IV fluids. This is crucial to identify any signs of fluid overload, such as crackles or wheezes. Administering the solution slowly over 24 hours (choice A) is not appropriate for an IV bolus, which is a rapid infusion. Changing the IV tubing every 12 hours (choice C) is a standard practice for preventing infection but is not directly related to administering an IV bolus. Flushing the IV line with heparin every 4 hours (choice D) is a maintenance practice to prevent clot formation in the line, not specifically related to administering an IV bolus.
