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. All of the following interventions are correct when using the Z-track method of drug injection except:

• A. Prepare the injection site with alcohol
• B. Use a needle that is at least 1” long
• C. Aspirate for blood before injection
• D. Rub the site vigorously after the injection to promote absorption

Correct answer: D

Rationale: When using the Z-track method of drug injection, it is important to prepare the injection site with alcohol to ensure cleanliness, use a needle that is at least 1” long to reach the muscle tissue, and aspirate for blood before injection to verify correct needle placement. However, rubbing the site vigorously after the injection is not recommended as it can cause medication to leak into subcutaneous tissue, compromising the medication's intended absorption and efficacy.

3. A healthcare provider is preparing to care for a client following chest tube placement. Which of the following items should NOT be available in the client's room?

• A. Oxygen
• B. Sterile water
• C. Enclosed hemostat clamps
• D. Indwelling urinary catheter

Correct answer: D

Rationale: Following chest tube placement, an indwelling urinary catheter is not typically needed or relevant to the care provided. Chest tube placement is primarily concerned with managing pleural effusion or pneumothorax, and urinary catheterization is not directly related to this procedure. Oxygen, sterile water, and enclosed hemostat clamps are commonly used items in the care of a client with a chest tube in place, to ensure proper oxygenation, maintain drainage system integrity, and manage any bleeding that may occur. Therefore, the indwelling urinary catheter should not be available in the client's room following chest tube placement.

4. 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.

5. 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.
