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 nurse is caring for an older adult client who becomes agitated when the nurse requests the client’s dentures be removed prior to surgery. Which of the following responses should the nurse make?

• A. You seem worried. Are you concerned someone may see you without your teeth?
• B. Don't worry, it’s just for the surgery.
• C. You need to follow the instructions.
• D. The dentures need to be removed for a reason.

Correct answer: D

Rationale: The correct response is to provide a clear rationale for the request, as stated in option D. By explaining the purpose behind removing the dentures, the nurse helps the client understand the necessity, which can reduce agitation and promote cooperation. Option A demonstrates empathy by addressing the client's potential concern about being seen without dentures but lacks a direct explanation. Option B dismisses the client's feelings with a casual statement that may not address the underlying issue. Option C is authoritarian and lacks empathy, potentially escalating the client's agitation.

3. A healthcare professional is caring for a group of clients. Which of the following measures should the professional take to prevent the spread of infection?

• A. Place a client with TB in a room with negative pressure airflow
• B. Use a disposable gown for contact precautions
• C. Place a client with MRSA in a private room
• D. Use a mask for clients with influenza

Correct answer: A

Rationale: Tuberculosis is an airborne infection, and placing a client with TB in a room with negative pressure airflow helps prevent the spread of the infection by containing the pathogens. This measure is crucial as it prevents the dissemination of TB droplet nuclei to other areas. Choice B, using a disposable gown for contact precautions, is important for preventing the transmission of infections spread by direct or indirect contact. Choice C, placing a client with MRSA in a private room, is essential to prevent the spread of MRSA through contact with others. Choice D, using a mask for clients with influenza, helps prevent the spread of influenza through respiratory droplets. However, negative pressure airflow is specifically required for airborne infections like TB, making it the most appropriate choice in this scenario.

4. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Increased serum hemoglobin levels
• D. Decreased serum potassium levels

Correct answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

5. A nurse on the IV team is conducting an in-service education program about the complications of IV therapy. Which of the following statements by an attendee indicates an understanding of the manifestations of infiltration? (Select all that apply.)

• A. “The temperature around the IV site is cooler.”
• B. “The rate of the infusion increases.”
• C. “The skin at the IV site is red.”
• D. “The IV dressing is damp.”

Correct answer: A

Rationale: The correct statement is: 'The temperature around the IV site is cooler.' Cooler temperature around the site is indicative of infiltration, where IV fluid leaks into the surrounding tissue, causing tissue swelling. The other options are incorrect: B) An increase in infusion rate is not a sign of infiltration; instead, it could indicate an issue with the infusion pump or the IV catheter. C) Redness around the IV site is more indicative of infection rather than infiltration. D) A damp IV dressing is more suggestive of a leak in the IV system, not infiltration.
