Nursing Elites

1. 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).

2. Which of the following statements about chest X-rays is false?

• A. There are contraindications for this test
• B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
• C. A signed consent is not required
• D. Eating, drinking, and medications are allowed before this test

Correct answer: A

Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.

3. A client has chronic pancreatitis. Which of the following dietary recommendations should be made?

• A. Coffee with creamer
• B. Lettuce with sliced avocados
• C. Broiled skinless chicken breast with brown rice
• D. None of the above

Correct answer: C

Rationale: Chronic pancreatitis requires a low-fat diet to reduce stress on the pancreas. Broiled skinless chicken breast with brown rice is a suitable option as it is low in fat. Coffee with creamer and lettuce with sliced avocados are not recommended for individuals with chronic pancreatitis due to their fat content. Choosing options high in fat can exacerbate symptoms and increase the workload on the pancreas, worsening the condition.

4. A client with COPD expresses concerns about leaving the house due to continuous oxygen use. What is an appropriate response by the nurse?

• A. There are portable oxygen delivery systems that you can take with you.
• B. When you go out, you can remove the oxygen and then reapply it when you get home.
• C. You probably will not be able to go out as much as you used to.
• D. Home health services will come to see you so you will not need to get out.

Correct answer: A

Rationale: For a client with COPD concerned about leaving the house while on continuous oxygen, the nurse should provide reassurance by mentioning the availability of portable oxygen delivery systems. These systems allow the client to maintain their oxygen therapy while being mobile, enabling them to go out and engage in activities outside the home. This response promotes independence and quality of life for the client, addressing their immediate concerns and offering a practical solution to their perceived limitation.

5. Which of the following is a sign or symptom of a hemolytic reaction to a blood transfusion?

• A. Hemoglobinuria
• B. Chest pain
• C. Urticaria
• D. Distended neck veins

Correct answer: A

Rationale: Hemoglobinuria is a characteristic sign of a hemolytic reaction to a blood transfusion. Hemolytic reactions can lead to the destruction of red blood cells, causing the release of hemoglobin into the urine, which presents as hemoglobinuria. Chest pain, urticaria, and distended neck veins are not specific signs of a hemolytic reaction and may be associated with other conditions or reactions.
