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. When providing mouth care to an unconscious client, what is the best position for the client?

• A. Fowler’s position
• B. Side-lying
• C. Supine
• D. Trendelenburg

Correct answer: B

Rationale: The best position for an unconscious client when providing mouth care is the side-lying position. This position helps prevent aspiration by allowing fluids to drain out of the mouth easily, reducing the risk of choking or aspiration pneumonia. Placing the client in a side-lying position also promotes comfort and safety during the procedure. The other options are not ideal for mouth care in an unconscious client: Fowler’s position may increase the risk of aspiration, the supine position can lead to aspiration as well, and Trendelenburg position is not recommended due to potential adverse effects on blood circulation and increased intracranial pressure.

3. 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.

4. Which instrument is used for auscultation?

• A. Percussion hammer
• B. Audiometer
• C. Stethoscope
• D. Sphygmomanometer

Correct answer: C

Rationale: Auscultation involves listening to internal sounds in the body, such as heart and lung sounds. The instrument used for auscultation is a stethoscope, which allows healthcare providers to listen to these sounds. The percussion hammer is used to elicit sounds on the body, the audiometer is used to measure hearing ability, and the sphygmomanometer is used to measure blood pressure. Therefore, the correct answer is 'Stethoscope.'

5. When removing a contaminated gown, what should be the first thing touched by the nurse?

• A. Waist tie and neck tie at the back of the gown
• B. Waist tie in front of the gown
• C. Cuffs of the gown
• D. Inside of the gown

Correct answer: A

Rationale: When removing a contaminated gown, the nurse should ensure the first thing touched is the waist tie and neck tie at the back of the gown. This procedure helps prevent contamination by ensuring that the outer surface of the gown, which is likely to be contaminated, is not touched during removal. By touching the back ties first, the nurse minimizes the risk of transferring any contaminants to themselves or the environment.
