1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. A healthcare professional in an emergency department is assessing a newly admitted client who is experiencing drooling and hoarseness following a burn injury. Which of the following actions should the healthcare professional take first?

• A. Obtain a baseline ECG.
• B. Obtain a blood specimen for ABG analysis.
• C. Insert an 18-gauge IV catheter.
• D. Administer 100% humidified oxygen.

Correct answer: D

Rationale: In a client experiencing drooling and hoarseness following a burn injury, airway compromise is a critical concern. Administering 100% humidified oxygen is the priority to ensure adequate oxygenation. This intervention takes precedence over obtaining baseline ECG, obtaining blood specimens, or inserting an IV catheter, as airway management and oxygenation are fundamental in the initial assessment and management of a client with potential airway compromise.

3. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.

4. Which action would break sterile technique while preparing a sterile field for a dressing change?

• A. Using sterile forceps instead of sterile gloves to handle a sterile item
• B. Touching the outside wrapper of sterilized material without sterile gloves
• C. Placing a sterile object at the edge of the sterile field
• D. Pouring out a small amount of solution (15 to 30 ml) before pouring it into a sterile container

Correct answer: B

Rationale: Touching the outside wrapper of sterilized material without sterile gloves can introduce contaminants and compromise the sterility of the item. It is crucial to maintain strict adherence to sterile technique to prevent infections and ensure patient safety during procedures.

5. A client has a new prescription for heparin therapy. Which of the following statements by the client should indicate an immediate concern for the nurse?

• A. ''I am allergic to morphine.''
• B. ''I take antacids several times a day.''
• C. ''I had a blood clot in my leg several years ago.''
• D. ''It hurts to take a deep breath.''

Correct answer: B

Rationale: The correct answer is the statement 'I take antacids several times a day.' Antacids can alter the absorption of heparin, potentially affecting its effectiveness and increasing the risk of clot formation. This is a significant concern as it can impact the therapeutic outcome of heparin therapy. The other statements are not directly related to potential complications or interactions with heparin therapy.
