Nursing Elites

1. 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.

2. A client with hypocalcemia is receiving calcium gluconate. What assessment finding requires immediate intervention?

• A. Decreased deep tendon reflexes.
• B. Wheezing and stridor.
• C. Decreased bowel sounds.
• D. Positive Chvostek's sign.

Correct answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.

3. Which intervention should be prioritized by the nurse when assessing tissue perfusion post-above knee amputation (AKA)?

• A. Evaluate the closest proximal pulse.
• B. Observe color and amount of wound drainage.
• C. Observe for swelling around the stump.
• D. Assess the skin elasticity of the stump.

Correct answer: A

Rationale: The correct answer is to evaluate the closest proximal pulse when assessing tissue perfusion post-above knee amputation (AKA). Checking the closest proximal pulse provides the best indication of tissue perfusion in the extremities after an AKA procedure. Observing the color and amount of wound drainage (Choice B) is important for wound care but does not directly assess tissue perfusion. Observing for swelling around the stump (Choice C) may indicate inflammation or fluid accumulation but is not the most direct way to assess tissue perfusion. Assessing the skin elasticity of the stump (Choice D) is more related to skin integrity and wound healing rather than tissue perfusion.

4. An older client with type 1 diabetes arrives at the clinic with abdominal cramping, vomiting, lethargy, and confusion. What should the nurse implement first?

• A. Start an IV infusion of normal saline.
• B. Obtain a serum potassium level.
• C. Administer the client's usual dose of insulin.
• D. Assess the pupillary response to light.

Correct answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.

5. After receiving hemodialysis, what is the nurse's priority assessment for a client with chronic kidney disease?

• A. Monitor the client's potassium level.
• B. Assess the client's blood pressure.
• C. Check the client's hemoglobin and hematocrit levels.
• D. Monitor for signs of infection.

Correct answer: A

Rationale: The correct answer is to monitor the client's potassium level. During hemodialysis, there is a risk of potassium shifting, which can lead to life-threatening arrhythmias if not properly managed. Assessing the potassium level is crucial to prevent complications. While assessing blood pressure, checking hemoglobin and hematocrit levels, and monitoring for signs of infection are important aspects of care for a client with chronic kidney disease, monitoring potassium levels takes precedence due to its immediate life-threatening potential post-dialysis.
