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. 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.

3. 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.

4. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

5. When a client is comatose and has advance directives stating a desire to avoid life-sustaining measures, but the family wants these measures, what action should the nurse take?

• A. Arrange for an ethics committee meeting to address the family's concerns.
• B. Support the family's decision and initiate life-sustaining measures.
• C. Complete an incident report.
• D. Encourage the family to contact an attorney.

Correct answer: A

Rationale: In this scenario, the nurse should prioritize the client's wishes as outlined in the advance directives. By arranging for an ethics committee meeting, the nurse can facilitate discussions between the family and healthcare team to ensure that the client's wishes are respected while addressing the concerns of the family. This approach promotes ethical decision-making and collaborative communication among all involved parties, ultimately aiming to provide the best possible care for the client while considering their autonomy and preferences.
