Nursing Elites

1. The nurse is caring for a client with chronic renal failure who is receiving dialysis. The client reports muscle cramps and tingling in the hands. Which laboratory result should the nurse monitor to identify the cause of these symptoms?

• A. Sodium
• B. Calcium
• C. Phosphate
• D. Potassium

Correct answer: B

Rationale: Muscle cramps and tingling in clients with chronic renal failure are often associated with hypocalcemia. Monitoring calcium levels is crucial to identify imbalances and manage symptoms appropriately. Sodium, phosphate, and potassium levels are important in renal failure but are not directly related to the symptoms of muscle cramps and tingling reported by the client.

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 nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

4. A client with a history of alcohol abuse presents with confusion and unsteady gait. The nurse suspects Wernicke's encephalopathy. Which treatment should the nurse anticipate?

• A. Thiamine supplementation
• B. Folic acid replacement
• C. Intravenous glucose
• D. Magnesium sulfate administration

Correct answer: A

Rationale: Wernicke's encephalopathy is a neurological condition commonly caused by a deficiency in thiamine, often seen in clients with chronic alcohol abuse. Thiamine supplementation is the primary treatment to prevent further neurological damage. Folic acid replacement (choice B) is not the correct treatment for Wernicke's encephalopathy. Intravenous glucose (choice C) may be necessary in some cases of Wernicke's encephalopathy, but thiamine supplementation takes precedence. Magnesium sulfate administration (choice D) is not indicated as the primary treatment for Wernicke's encephalopathy.

5. The client with a below-the-knee amputation is being taught about proper care of the residual limb. The most important point to emphasize would be

• A. Wrap the stump with an elastic bandage to prevent swelling
• B. Keep the skin on the stump clean and dry
• C. Use alcohol to cleanse the stump daily
• D. Apply moisturizing lotion to the stump daily

Correct answer: B

Rationale: The correct answer is B: Keep the skin on the stump clean and dry. This is crucial for preventing infection and promoting healing of the residual limb. Wrapping the stump with an elastic bandage can constrict blood flow and cause issues. Using alcohol to cleanse the stump daily can be too harsh and drying for the skin, leading to irritation. Applying moisturizing lotion daily is not as essential as keeping the skin clean and dry to prevent complications.
