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. 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.

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 patient is admitted to the hospital with complaints of nausea, vomiting, diarrhea, and severe abdominal pain. Which of the following would immediately alert the healthcare provider that the patient has bleeding from the GI tract?

• A. Complete blood count
• B. Guaiac test
• C. Vital signs
• D. Abdominal girth

Correct answer: B

Rationale: A positive guaiac test is used to detect the presence of occult (hidden) blood in the stool, suggesting bleeding from the gastrointestinal tract. It is a rapid screening test that can provide immediate information to the healthcare provider about possible gastrointestinal bleeding in patients presenting with symptoms such as nausea, vomiting, diarrhea, and severe abdominal pain.

5. A healthcare professional is providing information about tuberculosis to a group of clients at a local community center. Which of the following manifestations should the professional NOT include in the teaching?

• A. Persistent cough
• B. Weight gain
• C. Fatigue
• D. Night sweats

Correct answer: B

Rationale: Weight gain is not a typical manifestation of tuberculosis. The characteristic symptoms of tuberculosis include a persistent cough, fatigue, and night sweats. Weight loss, not weight gain, is a common symptom associated with tuberculosis due to the impact of the infection on the body's metabolism. Therefore, the healthcare professional should exclude weight gain from the teaching on tuberculosis manifestations.
