1. 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.

2. All of the following statements are true about donning sterile gloves except:

• A. The first glove should be picked up by grasping the inside of the cuff.
• B. The second glove should be picked up by inserting the gloved fingers under the cuff outside the glove.
• C. The gloves should be adjusted by sliding the gloved fingers under the sterile cuff and pulling the glove over the wrist.
• D. The inside of the glove is considered sterile.

Correct answer: D

Rationale: When donning sterile gloves, it is essential to maintain sterility. The correct way to don sterile gloves includes grasping the outside of the cuff to put on the first glove and inserting the gloved fingers under the cuff outside the glove to put on the second glove. Adjustments should be made by sliding the fingers under the sterile cuff. It is crucial to remember that once the inside of the glove is touched during the donning process, it is no longer considered sterile.

3. Which of the following statements about chest X-rays is false?

• A. There are contraindications for this test
• B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
• C. A signed consent is not required
• D. Eating, drinking, and medications are allowed before this test

Correct answer: A

Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.

4. What is the meaning of PRN?

• A. When advice
• B. Immediately
• C. When necessary
• D. Now

Correct answer: C

Rationale: The correct meaning of PRN is 'when necessary.' The abbreviation 'PRN' comes from the Latin term 'pro re nata,' which is commonly used in medical contexts to indicate that a medication should be taken as needed, not at scheduled intervals. Choice A ('When advice') is incorrect as PRN does not refer to seeking advice. Choice B ('Immediately') is incorrect as PRN does not imply urgency. Choice D ('Now') is incorrect as PRN does not mean 'immediate' but rather 'as needed.' Therefore, the correct answer is C, 'When necessary.'

5. Which technique in physical examination is used to assess the movement of air through the tracheobronchial tree?

• A. Palpation
• B. Auscultation
• C. Inspection
• D. Percussion

Correct answer: B

Rationale: The correct answer is B: Auscultation. Auscultation is a technique in physical examination used to assess the movement of air through the tracheobronchial tree. During auscultation, healthcare providers listen to lung sounds using a stethoscope to detect abnormalities such as wheezing, crackles, or diminished breath sounds, which can indicate conditions affecting the airways or lungs. Palpation (Choice A) involves feeling the body for abnormalities, Inspection (Choice C) involves visual examination, and Percussion (Choice D) involves tapping on the body to produce sounds that can help in assessing underlying structures, but they are not directly used to assess air movement through the tracheobronchial tree.
