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. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

3. The client has been diagnosed with hypertension, and the nurse is providing education on dietary changes. Which food should the client be advised to avoid?

• A. Bananas
• B. Processed meats
• C. Low-fat yogurt
• D. Whole grains

Correct answer: B

Rationale: Processed meats should be avoided by clients with hypertension as they are high in sodium, which can contribute to elevated blood pressure. It is essential to limit the intake of high-sodium foods to help manage hypertension. Bananas, low-fat yogurt, and whole grains are generally beneficial for heart health due to their nutrient content and should not be avoided in a heart-healthy diet.

4. A nurse finds a pregnant client at 33 weeks gestation in cardiac arrest. What modification to cardiopulmonary resuscitation (CPR) should the nurse implement?

• A. Administer chest compressions at a faster rate.
• B. Position a firm wedge under the client’s pelvis and thorax at a 30-degree tilt.
• C. Position the client flat with legs elevated.
• D. Call for immediate assistance and prepare for a cesarean section.

Correct answer: B

Rationale: In a pregnant client at 33 weeks gestation, performing CPR requires tilting the pelvis and thorax at a 30-degree angle to relieve pressure on the vena cava, ensuring proper circulation during compressions. Administering chest compressions at a faster rate (Choice A) may not address the specific needs of a pregnant client in cardiac arrest. Positioning the client flat with legs elevated (Choice C) is not recommended as it can worsen vena cava compression. Calling for immediate assistance and preparing for a cesarean section (Choice D) should be considered only after initiating appropriate CPR modifications.

5. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?

• A. Three apricots
• B. Medium banana
• C. Naval orange
• D. Baked potato

Correct answer: D

Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.
