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. If a patient's blood pressure is 150/96, what is his pulse pressure?

• A. 54
• B. 96
• C. 150
• D. 246

Correct answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

3. What is a muscular enlarged pouch or sac that lies slightly to the left and is used for the temporary storage of food?

• A. Gallbladder
• B. Urinary bladder
• C. Stomach
• D. Lungs

Correct answer: C

Rationale: The correct answer is the stomach. The stomach is a muscular organ located slightly to the left in the abdominal cavity. It serves as a temporary storage site for food where it is mixed with digestive enzymes and acids to begin the process of digestion. The gallbladder (Choice A) is not involved in food storage; it stores bile produced by the liver. The urinary bladder (Choice B) is part of the urinary system and stores urine. The lungs (Choice D) are responsible for respiration, not food storage.

4. A healthcare professional in the emergency department is assessing a client who has a suspected flail chest. Which of the following findings should the professional not expect?

• A. Bradycardia
• B. Cyanosis
• C. Hypotension
• D. Dyspnea

Correct answer: A

Rationale: Bradycardia is not typically associated with a flail chest. Flail chest is characterized by paradoxical chest wall movement, respiratory distress, and hypoxia, but it does not usually cause bradycardia. The other options, such as cyanosis (bluish discoloration of the skin due to poor oxygenation), hypotension (low blood pressure), and dyspnea (difficulty breathing), are commonly seen in patients with flail chest due to the underlying respiratory compromise.

5. A healthcare professional is assessing a client who has a pulmonary embolism. Which of the following information should the healthcare professional not expect to find?

• A. Bradypnea
• B. Pleural friction rub
• C. Petechiae
• D. Tachycardia

Correct answer: A

Rationale: In a client with a pulmonary embolism, bradypnea, which is abnormally slow breathing, is not an expected finding. Pulmonary embolism typically presents with tachypnea (rapid breathing) due to the body's compensatory mechanism to increase oxygen levels. Pleural friction rub, petechiae, and tachycardia are commonly associated with a pulmonary embolism due to the impaired oxygenation and increased workload on the heart. Therefore, the healthcare professional should not expect to find bradypnea during the assessment of a client with a pulmonary embolism.
