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. The healthcare professional must verify the client’s identity before the administration of medication. Which of the following is the safest way to identify the client?

• A. Ask the client for their name
• B. Check the client’s identification band
• C. State the client’s name aloud and ask the client to repeat it
• D. Check the room number

Correct answer: B

Rationale: Verifying the client's identity before administering medication is crucial to ensure patient safety. Checking the client’s identification band is the safest and most reliable method to confirm the client's identity. Identification bands are specifically designed to prevent errors in patient identification and help healthcare professionals administer care to the correct individual. Asking the client for their name (Choice A) may lead to errors if the client is unable to communicate or if there is a language barrier. Stating the client’s name aloud and asking them to repeat it (Choice C) relies on the client's ability to respond accurately. Checking the room number (Choice D) does not directly confirm the client's identity and may lead to errors if multiple patients are in the same room.

3. A client is in a seclusion room following violent behavior and continues to display aggressive behavior. What action should the nurse take?

• A. Confront the client about this behavior.
• B. Express sympathy for the client's situation.
• C. Speak assertively to the client.
• D. Stand within 30 cm (1 ft) of the client when speaking with them.

Correct answer: A

Rationale: When a client in a seclusion room following violent behavior continues to display aggression, it is essential for the nurse to confront the client about this behavior. Confrontation can help set boundaries, address the behavior, and ensure the safety of both the client and the healthcare team. Expressing sympathy (Choice B) may not address the immediate need for behavior management. Speaking assertively (Choice C) can be important but should be coupled with addressing the specific behavior. Standing within close proximity (Choice D) of an aggressive client can escalate the situation and compromise safety, so it is not the appropriate action to take.

4. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

5. When assessing a client with a history of asthma, which of the following factors should the nurse identify as a risk for asthma?

• A. Gender
• B. Environmental allergies
• C. Alcohol
• D. None of the above

Correct answer: B

Rationale: When assessing a client with a history of asthma, the nurse should identify environmental allergies as a risk factor for asthma. Environmental allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms and exacerbate the condition. Gender, alcohol consumption, and other factors may not directly contribute to the development or exacerbation of asthma.
