Nursing Elites

1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

2. The client is planning care for a client who is receiving hemodialysis. Which of the following interventions should be included in the plan of care?

• A. Administer anticoagulants to prevent clot formation.
• B. Monitor the client for signs of infection.
• C. Provide the client with a high-protein diet.
• D. Encourage the client to drink at least 2 liters of fluid daily.

Correct answer: B

Rationale: Monitoring for signs of infection is crucial in clients receiving hemodialysis because they are at an increased risk of infection due to the invasive nature of the procedure. Administering anticoagulants is not typically a part of the routine care for clients undergoing hemodialysis unless specifically prescribed. While a high-protein diet may be beneficial for some clients, it is not a specific intervention related to hemodialysis. Encouraging fluid intake must be individualized based on the client's fluid status and should not be a generalized recommendation for all clients receiving hemodialysis.

3. Which of the following is a primary intervention for a patient with sepsis?

• A. Administering antibiotics
• B. Administering IV fluids
• C. Administering antipyretics
• D. Monitoring blood cultures

Correct answer: D

Rationale: Monitoring blood cultures is a primary intervention for a patient with sepsis because it helps identify the causative organism, which is crucial in guiding appropriate antibiotic therapy. Administering antibiotics (Choice A) is important in treating sepsis but is considered a secondary intervention. Administering IV fluids (Choice B) is also crucial for sepsis management to restore perfusion and hemodynamic stability. Administering antipyretics (Choice C) may help reduce fever, but it is not a primary intervention for managing sepsis.

4. A client who is mouth breathing is receiving oxygen by face mask. The nursing assistant asks the nurse why a water bottle is attached to the oxygen tubing near the wall oxygen outlet. The nurse responds that the primary purpose of the water is to:

• A. Prevent the client from getting a nosebleed
• B. Give the client added fluid by way of the respiratory tree
• C. Humidify the oxygen that is bypassing the client’s nose
• D. Prevent fluid loss from the lungs during mouth breathing

Correct answer: C

Rationale: The purpose of the water bottle is to humidify the oxygen that is bypassing the nose during mouth breathing. When a client breathes through the mouth, the oxygen delivered by the face mask bypasses the natural humidification provided by the nasal passages. Therefore, the water bottle attachment helps to add moisture to the oxygen, preventing dryness and irritation to the respiratory tract. Choices A, B, and D are incorrect. Clients breathing through the mouth are not at risk for nosebleeds, do not receive added fluid through the respiratory tree, and do not experience fluid loss from the lungs due to mouth breathing.

5. A client is scheduled to undergo computerized tomography (CT) with contrast for evaluation of an abdominal mass. The nurse should tell the client that:

• A. The test may be painful
• B. The test takes 2 to 3 hours
• C. Food and fluids are not allowed for 4 hours after the test
• D. Dye is injected and may cause a warm flushing sensation

Correct answer: D

Rationale: The correct answer is D. A contrast-aided CT scan involves the injection of dye to enhance the images obtained. The dye may cause a warm flushing sensation when injected, which is a common side effect. Choices A, B, and C are incorrect. CT with contrast is generally not a painful procedure, the duration of the test does not usually take 2 to 3 hours, and restrictions on food and fluids are typically before the test, not afterward.
