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

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 not a cause of tachycardia?

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

3. A client is scheduled for a thoracentesis. Which of the following supplies should NOT be in the client's room?

Correct answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.

4. Which hormone is secreted by the Islets of Langerhans?

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.

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

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.
