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 provider is caring for a group of clients. Which of the following clients is not at risk for pulmonary embolism?

• A. A client who has a BMI of 30
• B. A female client who is postmenopausal
• C. A client who has a fractured femur
• D. A client who has chronic atrial fibrillation

Correct answer: B

Rationale: Postmenopausal status is not a significant risk factor for pulmonary embolism. Risk factors for pulmonary embolism include obesity (BMI of 30 or higher), immobility such as having a fractured femur, and conditions like chronic atrial fibrillation that increase the risk of blood clot formation. While postmenopausal status may be associated with other health risks, it is not directly linked to an increased risk of pulmonary embolism.

3. A healthcare professional is reviewing laboratory data for a client who has chronic kidney disease. Which of the following findings should the healthcare professional expect?

• A. Increased creatinine.
• B. Increased hemoglobin.
• C. Increased bicarbonate.
• D. Increased calcium.

Correct answer: A

Rationale: In chronic kidney disease, the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of creatinine. Creatinine levels are commonly elevated in individuals with impaired kidney function, making it a key indicator of kidney health. Therefore, an increased creatinine level would be an expected finding in a client with chronic kidney disease.

4. When caring for a client on pressure support ventilation (PSV), which statement by the nurse indicates an understanding of PSV?

• A. It keeps the alveoli open and prevents atelectasis.
• B. It allows preset pressure delivered during spontaneous ventilation.
• C. It guarantees minimal minute ventilator.
• D. It delivers a preset ventilatory rate and tidal volume to the client.

Correct answer: B

Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.

5. A client has generalized petechiae and ecchymoses. The nurse should expect a prescription for which of the following laboratory tests?

• A. Platelet count
• B. Potassium level
• C. Creatinine clearance
• D. Prealbumin

Correct answer: A

Rationale: Generalized petechiae and ecchymoses can indicate a potential issue with platelet function or count. Therefore, the most relevant laboratory test to evaluate this condition would be a platelet count. Platelet count helps assess the number of platelets in the blood, which are crucial for clotting and preventing bleeding. Monitoring platelet levels can provide important information about a client's bleeding risk and overall hematologic health.
