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. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

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.

3. When discussing hair loss with Mrs. Lim, who begins to cry, the best response would be:

• A. Don’t worry. It’s only temporary
• B. Why are you crying? I didn’t get to the bad news yet
• C. Your hair is really pretty
• D. I know this will be difficult for you, but your hair will grow back after the completion of chemotherapy

Correct answer: D

Rationale: When a patient is emotionally affected, it is essential to acknowledge their feelings while providing reassurance and information. Option D demonstrates empathy by acknowledging the difficulty Mrs. Lim is facing and offers hope by reassuring her that her hair will grow back after chemotherapy, which can provide comfort and support during a challenging time.

4. A healthcare professional is assessing a client following a gunshot wound to the chest. For which of the following findings should the healthcare professional not monitor to detect a pneumothorax?

• A. Tachypnea
• B. Deviation of the trachea
• C. Bradycardia
• D. Pleuritic pain

Correct answer: C

Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

5. According to the principles of standard precautions, when should gloves be worn by healthcare providers?

• A. Providing a back massage
• B. Feeding a client
• C. Providing hair care
• D. Providing oral hygiene

Correct answer: D

Rationale: Gloves should be worn when providing oral hygiene as it involves potential exposure to bodily fluids, aligning with the standard precautions to prevent the transmission of infections. Providing a back massage, feeding a client, and providing hair care do not typically involve direct exposure to bodily fluids, so wearing gloves is not necessary in these scenarios according to standard precautions.
