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. A healthcare provider is assessing a client who has left-sided heart failure. Which of the following should the healthcare provider identify as a manifestation of pulmonary congestion?

• A. Frothy, pink sputum
• B. Jugular vein distention
• C. Weight gain
• D. Bradypnea

Correct answer: A

Rationale: Pulmonary congestion is a common manifestation of left-sided heart failure. When the left side of the heart fails, blood backs up into the lungs, leading to pulmonary congestion. This can result in symptoms such as frothy, pink-tinged sputum due to the presence of blood in the respiratory secretions. Jugular vein distention, weight gain, and bradypnea are also associated with heart failure, but frothy, pink sputum specifically indicates pulmonary congestion in this scenario.

3. A client is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?

• A. Hip arthroplasty 2 weeks ago
• B. Elevated sedimentation rate
• C. Incident of exercise-induced asthma 1 week ago
• D. Elevated platelet count

Correct answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

4. Which action would break sterile technique while preparing a sterile field for a dressing change?

• A. Using sterile forceps instead of sterile gloves to handle a sterile item
• B. Touching the outside wrapper of sterilized material without sterile gloves
• C. Placing a sterile object at the edge of the sterile field
• D. Pouring out a small amount of solution (15 to 30 ml) before pouring it into a sterile container

Correct answer: B

Rationale: Touching the outside wrapper of sterilized material without sterile gloves can introduce contaminants and compromise the sterility of the item. It is crucial to maintain strict adherence to sterile technique to prevent infections and ensure patient safety during procedures.

5. What is the most common injury among elderly persons?

• A. Atherosclerotic changes in the blood vessels
• B. Increased incidence of gallbladder disease
• C. Urinary Tract Infection
• D. Hip fracture

Correct answer: D

Rationale: Hip fracture is the most common injury among elderly persons. As people age, their bones become more fragile, making them more susceptible to hip fractures, often resulting from falls. These fractures can significantly impact an elderly person's quality of life and mobility, making them a significant concern in geriatric care.
