Nursing Elites

1. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

2. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

3. Which nursing diagnosis would be a priority for a client admitted with a CVA (cerebral vascular accident)?

• A. Risk for aspiration
• B. Impaired physical mobility
• C. Disturbed sensory perception
• D. Interrupted family processes

Correct answer: A

Rationale: The correct answer is 'Risk for aspiration' as it is a priority concern in clients with a CVA due to potential swallowing difficulties. Aspiration poses immediate risks such as pneumonia, which can be life-threatening. Impaired physical mobility, while important, may not be as urgent as the risk for aspiration in this scenario. Disturbed sensory perception and interrupted family processes are not typically the most critical concerns in the acute phase of a CVA.

4. While changing a client's postoperative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given there is a positive MRSA, which is the most important action for the nurse to take?

• A. Force oral fluids
• B. Request a nutrition consult
• C. Initiate contact precautions
• D. Limit visitors to immediate family only

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to initiate contact precautions. MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacterium that spreads through direct contact. Contact precautions involve wearing gloves and gowns to prevent the spread of infection to other patients or healthcare workers. Force-feeding oral fluids, requesting a nutrition consult, or limiting visitors to immediate family only are not the most appropriate actions in this scenario. These actions do not directly address the need to prevent the spread of MRSA, which is crucial in a healthcare setting.

5. What is the first step a healthcare professional should take when preparing to provide tracheostomy care?

• A. Perform hand hygiene
• B. Gather equipment
• C. Explain the procedure
• D. Assess the client

Correct answer: A

Rationale: Performing hand hygiene is the initial step a healthcare professional should take when preparing to provide tracheostomy care. This step is crucial to prevent the transmission of pathogens and reduce the risk of infection to the client. By cleansing the hands, the healthcare professional ensures patient safety. While gathering equipment, explaining the procedure, and assessing the client are essential components of tracheostomy care, they should occur after performing hand hygiene to maintain aseptic technique and minimize the risk of introducing harmful microorganisms to the client.
