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 professional is assessing a client who has experienced a left-hemispheric stroke. Which of the following is an expected finding?

• A. Impulse control difficulty
• B. Poor judgement
• C. Inability to recognize familiar objects
• D. Loss of depth perception

Correct answer: C

Rationale: Patients who have experienced a left-hemispheric stroke may exhibit symptoms of agnosia, which is the inability to recognize familiar objects or people. This occurs due to damage to the right hemisphere of the brain, which is responsible for visual and spatial perception. Impulse control difficulty, poor judgment, and loss of depth perception are not typically associated with left-hemispheric strokes.

3. Which of the following patients is at greater risk for contracting an infection?

• A. A patient with leukopenia
• B. A patient receiving broad-spectrum antibiotics
• C. A postoperative patient who has undergone orthopedic surgery
• D. A newly diagnosed diabetic patient

Correct answer: A

Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.

4. Which of the following actions should be taken to use a wide base support when assisting a client to get up in a chair?

• A. Bend at the waist and place arms under the client’s arms and lift
• B. Face the client, bend knees, and place hands on the client’s forearm and lift
• C. Spread the feet apart
• D. Tighten the pelvic muscles

Correct answer: C

Rationale: The correct answer is C: Spread the feet apart. When assisting a client to get up in a chair, it is crucial to use a wide base of support to maintain stability and prevent injuries. Spreading the feet apart provides a broader base, increasing balance and support for both the client and the caregiver. This position helps distribute the weight evenly and allows for better control when assisting the client in moving. Choices A, B, and D are incorrect because bending at the waist, placing arms under the client's arms, tightening pelvic muscles, or placing hands on the client's forearm do not provide the necessary wide base support needed for stability and safety during the transfer process.

5. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.
