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 is being assessed by a nurse who is 30 minutes postoperative following an arterial thrombectomy. Which of the following findings should the nurse report?

• A. Chest pain
• B. Muscle spasms
• C. Cool, moist skin
• D. Incisional pain

Correct answer: A

Rationale: Chest pain is a critical finding postoperatively, especially after an arterial thrombectomy, as it could indicate complications like myocardial infarction or pulmonary embolism. It requires immediate attention and further evaluation. Muscle spasms, cool moist skin, and incisional pain are important to assess but not as urgent as chest pain in this scenario.

3. Which of the following principles of primary nursing has proven the most satisfying to the patient and nurse?

• A. Administer oxygen by Venturi mask at 24% as needed
• B. Allow a 1-hour rest period between activities
• C. Patients and nurses both respond well to primary nursing care units
• D. Studies have shown that patients and nurses both respond well to primary nursing care units

Correct answer: C

Rationale: Primary nursing care units have been proven to be highly satisfying for both patients and nurses. This model promotes a consistent and continuous relationship between a patient and a primary nurse, leading to improved communication, personalized care, and overall satisfaction for both parties involved.

4. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. 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.
