Nursing Elites

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. During an assessment, a healthcare provider observes a client with a chest tube and drainage system. What is an expected finding?

• A. Continuous bubbling in the water seal chamber
• B. Gentle constant bubbling in the suction control chamber
• C. Drainage system positioned upright at chest level
• D. Exposed sutures without dressing

Correct answer: B

Rationale: When assessing a client with a chest tube and drainage system, gentle constant bubbling in the suction control chamber is an expected finding. This indicates that the system is functioning properly. Continuous bubbling in the water seal chamber would suggest an air leak, the drainage system should be positioned upright at chest level to promote proper drainage, and exposed sutures without dressing would be an incorrect finding as they should be covered to prevent infection.

3. A client is receiving vecuronium for acute respiratory distress syndrome. Which of the following medications should the nurse anticipate administering with this medication?

• A. Fentanyl
• B. Furosemide
• C. Famotidine
• D. Dexamethasone

Correct answer: A

Rationale: Vecuronium is a neuromuscular blocking agent used for muscle relaxation during mechanical ventilation. When administering vecuronium, it is common to also give an opioid analgesic, such as fentanyl, to manage pain and ensure the patient's comfort. Fentanyl is often used in combination with neuromuscular blocking agents to provide balanced anesthesia, making it the appropriate medication to anticipate administering in this scenario.

4. How many ounces are in 1 cup?

• A. 8
• B. 80
• C. 800
• D. 8000

Correct answer: A

Rationale: 1 cup is equivalent to 8 ounces. This conversion is commonly used in cooking and baking recipes, where precise measurements are crucial for the successful outcome of dishes. Knowing this conversion helps ensure that ingredients are accurately measured and the recipe turns out as intended. Choices B, C, and D are incorrect because they do not reflect the correct conversion between cups and ounces. 80, 800, and 8000 ounces are significantly higher quantities than what is found in 1 cup, which is 8 ounces.

5. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.
