1. Which action should the nurse take to reduce the risk of ventilator-associated pneumonia in a client with an endotracheal tube receiving mechanical ventilation?

• A. Position the head of the client's bed flat
• B. Turn the client every 4 hours
• C. Brush the client's teeth with a suction toothbrush every 12 hours
• D. Provide humidity by maintaining moisture within the ventilator tubing

Correct answer: C

Rationale: Ventilator-associated pneumonia (VAP) is a common complication in clients receiving mechanical ventilation. Oral hygiene is crucial in reducing the risk of VAP. Brushing the client's teeth with a suction toothbrush every 12 hours helps prevent bacterial colonization in the oral cavity, which can be aspirated into the lungs. Positioning the head of the bed flat can increase the risk of aspiration. Turning the client every 4 hours is important for preventing pressure ulcers but not directly related to reducing VAP. Providing humidity in the ventilator tubing helps maintain airway moisture but does not directly address the risk of VAP.

2. How does the pain of a myocardial infarction (MI) differ from stable angina?

• A. Accompanied by shortness of breath
• B. Feelings of fear or anxiety
• C. Lasts about 3-5 minutes
• D. Relieved by taking nitroglycerin

Correct answer: A

Rationale: The pain of an MI is often accompanied by shortness of breath and feelings of fear or anxiety. It typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Unlike stable angina, the pain of an MI occurs without a known cause such as exertion.

3. A client has developed atelectasis postoperatively. Which of the following findings should the nurse expect?

• A. Facial flushing
• B. Increasing dyspnea
• C. Decreasing respiratory rate
• D. Friction rub

Correct answer: B

Rationale: Atelectasis is a condition where the alveoli in the lungs collapse, leading to impaired gas exchange. As a result, the client may experience increasing dyspnea (difficulty breathing) due to the decreased lung capacity for oxygen exchange. Facial flushing, decreasing respiratory rate, and friction rub are not typically associated with atelectasis.

4. A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.

5. A healthcare professional is caring for four clients on intravenous heparin therapy. Which lab value possibly indicates a serious side effect has occurred?

• A. Hemoglobin: 14.2 g/dL
• B. Platelet count: 82,000/µL
• C. RBC count: 4.8 x 10^6/µL
• D. WBC count: 8.7 x 10^3/µL

Correct answer: B

Rationale: A low platelet count, as seen in choice B, is concerning as it could indicate heparin-induced thrombocytopenia, a serious side effect of heparin therapy. Heparin-induced thrombocytopenia can lead to an increased risk of blood clotting, potentially causing severe complications. Monitoring platelet counts is crucial during heparin therapy to promptly identify and manage this adverse effect.
