Nursing Elites

1. The nurse is teaching a client about postoperative care following a total knee arthroplasty. What instruction should the nurse prioritize?

• A. Begin ambulation as soon as possible.
• B. Use continuous passive motion therapy to maintain joint mobility.
• C. Avoid putting weight on the affected leg.
• D. Apply ice packs to reduce pain and swelling.

Correct answer: B

Rationale: The correct answer is B: 'Use continuous passive motion therapy to maintain joint mobility.' Continuous passive motion therapy is crucial in postoperative care following a total knee arthroplasty as it helps prevent stiffness and maintain joint mobility. Ambulation is important but should be guided and not immediate. Avoiding putting weight on the affected leg is also essential initially to prevent complications. Applying ice packs can help reduce pain and swelling, but it is not the priority instruction for maintaining joint mobility and preventing stiffness.

2. A client with pneumonia is receiving intravenous (IV) antibiotics. Which assessment finding indicates that the client's condition is improving?

• A. Client's respiratory rate decreases from 24 to 20 breaths per minute
• B. White blood cell count decreases to normal range
• C. Client reports increased energy levels
• D. Cough becomes productive with green sputum

Correct answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.

3. A client is scheduled for a colonoscopy. Which preparation is the most important for the nurse to implement?

• A. Administer an enema before the procedure.
• B. Ensure the client is NPO after midnight.
• C. Encourage the client to drink clear liquids.
• D. Verify the client has completed the bowel preparation.

Correct answer: D

Rationale: The correct answer is to verify that the client has completed the bowel preparation. This step is crucial to ensure the colon is clear for accurate visualization during the procedure. Administering an enema before the procedure may not always be necessary and can be uncomfortable for the client. Ensuring the client is NPO after midnight is important, but verifying bowel preparation takes precedence. Encouraging the client to drink clear liquids is a part of the preparation process but not the most critical step compared to verifying completion of bowel preparation.

4. A nurse from the maternity unit is floated to the critical care unit because of staff shortage on the evening shift. Which client would be appropriate to assign to this nurse?

• A. A client with a Dopamine drip IV with vital signs monitored every 5 minutes
• B. A client with a myocardial infarction that is free from pain and dysrhythmias
• C. A client with a tracheotomy of 24 hours in some respiratory distress
• D. A client with a pacemaker inserted this morning with intermittent capture

Correct answer: B

Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.

5. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
