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. Which of the following interventions promotes patient safety?

• A. Assess the patient’s ability to ambulate and transfer from a bed to a chair
• B. Demonstrate the signal system to the patient
• C. Check to see that the patient is wearing their identification band
• D. All of the above

Correct answer: D

Rationale: All the listed interventions are essential for promoting patient safety. Assessing the patient’s ability to ambulate and transfer helps prevent falls, demonstrating the signal system ensures effective communication in emergencies, and checking the patient's identification band aids in accurate identification and treatment. By combining these interventions, healthcare providers can enhance patient safety and quality of care.

3. A client has had a cast applied, and a nurse is providing care. Which of the following actions should the nurse take first?

• A. Place an ice pack over the cast.
• B. Palpate the pulse distal to the cast.
• C. Teach the client to keep the cast clean and dry.
• D. Position the casted extremity on a pillow.

Correct answer: B

Rationale: When caring for a client with a newly applied cast, the nurse's priority should be to assess the circulation by palpating the pulse distal to the cast. This is crucial to ensure there is no compromise in blood flow, which could lead to serious complications. Placing an ice pack over the cast, teaching the client about cast care, and positioning the casted extremity on a pillow are important interventions but should follow the assessment of circulation.

4. What is the best position for examining the rectum?

• A. Prone
• B. Sim's
• C. Knee-chest
• D. Lithotomy

Correct answer: C

Rationale: The knee-chest position is the most optimal position for examining the rectum. In this position, the patient kneels on the examination table with their chest resting on it, creating a straight line from the head to the lower back. This position allows for easier access and visualization of the rectal area, making it the preferred choice for rectal examinations. Prone position (choice A) is lying face down and is not ideal for rectal exams as it does not provide good access. Sim's position (choice B) is lying on the left side with the right knee and thigh flexed, also not ideal for rectal exams. Lithotomy position (choice D) is lying on the back with legs flexed and feet in stirrups, primarily used for gynecological exams and surgery, not for rectal examinations.

5. Which of the following substances increase the amount of urine produced?

• A. Caffeine-containing drinks, such as coffee and cola
• B. Beets
• C. Urinary analgesics
• D. Kaolin with pectin (Kaopectate)

Correct answer: A

Rationale: Caffeine is a diuretic, which means it increases urine production by promoting the excretion of water from the body through the kidneys. Therefore, substances like caffeine-containing drinks, such as coffee and cola, can lead to an increase in the amount of urine produced.
