1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. Which of the following is the correct meaning of CBR?

• A. Cardiac Board Room
• B. Complete Bathroom
• C. Complete Bed Rest
• D. Complete Board Room

Correct answer: C

Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.

3. A male patient who had surgery 2 days ago for head and neck cancer is about to make his first attempt to ambulate outside his room. The nurse notes that he is steady on his feet and that his vision was unaffected by the surgery. Which of the following nursing interventions would be appropriate?

• A. Encourage the patient to walk in the hall alone
• B. Discourage the patient from walking in the hall for a few more days
• C. Accompany the patient for his walk
• D. Consult a physical therapist before allowing the patient to ambulate

Correct answer: C

Rationale: Accompanying the patient for his walk is the appropriate nursing intervention in this scenario to ensure his safety during his first ambulation. This allows the nurse to provide immediate assistance if needed and ensures the patient's well-being during this critical postoperative period.

4. During the removal of a chest tube, what should the nurse instruct the client to do?

• A. Lie on their left side.
• B. Use the incentive spirometer.
• C. Cough at regular intervals.
• D. Perform the Valsalva maneuver.

Correct answer: D

Rationale: During the removal of a chest tube, instructing the client to perform the Valsalva maneuver is essential. This maneuver involves holding the breath and bearing down, which helps prevent air from entering the pleural space during tube removal, reducing the risk of pneumothorax. Instructing the client to lie on their left side, use the incentive spirometer, or cough at regular intervals is not appropriate during the chest tube removal process.

5. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.
