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 client with vision loss is under the care of a nurse. Which of the following actions should the nurse AVOID?

• A. Keep objects in the client's room in the same place
• B. Ensure there is high-wattage lighting in the client's room
• C. Approach the client from the side
• D. Allow extra time for the client to perform tasks

Correct answer: C

Rationale: Approaching a client with vision loss from the side can startle them and may lead to accidents or discomfort. It is important to approach them from the front so they are aware of your presence. Keeping objects in the same place aids in familiarity and reduces the risk of falls. High-wattage lighting enhances visibility for the client. Allowing extra time for tasks accommodates the client's potential slower pace and ensures they can perform tasks safely.

3. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

• A. Confusion
• B. Pale skin
• C. Bradycardia
• D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

4. A client has global aphasia affecting both receptive and expressive language abilities. Which intervention should NOT be included in the client's care plan?

• A. Speak to the client at a slower rate.
• B. Assist the client in using flash cards with pictures.
• C. Speak to the client in a loud voice.
• D. Give instructions one step at a time.

Correct answer: C

Rationale: Individuals with global aphasia have difficulty understanding and expressing language. Speaking loudly may not improve comprehension and can be perceived as aggressive. Therefore, it is important not to speak loudly to a client with global aphasia. Speaking at a slower rate, using visual aids like flash cards, and breaking down instructions into simple steps can facilitate communication and understanding for the client.

5. What is the most appropriate nursing order for a patient who develops dyspnea and shortness of breath?

• A. Maintain the patient on strict bed rest at all times
• B. Maintain the patient in an orthopneic position as needed
• C. Administer high-flow oxygen immediately
• D. Encourage the patient to engage in vigorous physical activity

Correct answer: B

Rationale: Maintaining the patient in an orthopneic position as needed is the most appropriate nursing order for a patient experiencing dyspnea and shortness of breath. This position helps to optimize lung expansion, improve oxygenation, and alleviate breathing difficulties. It is a strategic intervention to enhance respiratory function in patients with respiratory distress. Choice A is incorrect because strict bed rest may not address the underlying respiratory issue effectively. Choice C is premature as administering high-flow oxygen should be based on a comprehensive assessment. Choice D is inappropriate as encouraging vigorous physical activity can exacerbate breathing problems in a patient experiencing dyspnea.
