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

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

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.

2. 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.

3. A healthcare provider is preparing to care for a client following chest tube placement. Which of the following items should NOT be available in the client's room?

• A. Oxygen
• B. Sterile water
• C. Enclosed hemostat clamps
• D. Indwelling urinary catheter

Correct answer: D

Rationale: Following chest tube placement, an indwelling urinary catheter is not typically needed or relevant to the care provided. Chest tube placement is primarily concerned with managing pleural effusion or pneumothorax, and urinary catheterization is not directly related to this procedure. Oxygen, sterile water, and enclosed hemostat clamps are commonly used items in the care of a client with a chest tube in place, to ensure proper oxygenation, maintain drainage system integrity, and manage any bleeding that may occur. Therefore, the indwelling urinary catheter should not be available in the client's room following chest tube placement.

4. A client had oral surgery following a motor vehicle accident. The nurse assessing the client finds the skin flushed and warm. Which of the following would be the best method to take the client’s body temperature?

• A. Oral
• B. Axillary
• C. Arterial line
• D. Rectal

Correct answer: D

Rationale: In cases where the oral route is contraindicated due to oral surgery or altered consciousness, the rectal method is preferred for the most accurate body temperature reading. This method is particularly useful when the skin is flushed and warm, as it provides a reliable reflection of core body temperature despite external factors affecting the skin temperature. Axillary temperature may not be as accurate as rectal temperature due to variations caused by environmental factors and technique. Arterial line temperature monitoring is invasive and not typically used for routine temperature assessment.

5. How many drops are equivalent to 1 tsp?

• A. 15
• B. 60
• C. 10
• D. 30

Correct answer: B

Rationale: 1 teaspoon (tsp) is equivalent to approximately 60 drops. Drops and teaspoons vary in volume and size, affecting the conversion ratio. Choice A (15 drops) is incorrect as it's a common misconception. Choice C (10 drops) and Choice D (30 drops) do not align with the standard conversion of 1 tsp to 60 drops.
