1. 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.

2. What is the appropriate needle gauge for intradermal injection?

• A. 20G
• B. 22G
• C. 25G
• D. 26G

Correct answer: D

Rationale: Intradermal injections require a very fine needle to be used to deliver the medication into the dermis layer of the skin. A 26G needle is typically used for intradermal injections as it is thin enough to penetrate the skin's surface and deposit the medication accurately.

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. Examples of patients suffering from impaired awareness include all of the following except:

• A. A semiconscious or overfatigued patient
• B. A disoriented or confused patient
• C. A patient who cannot care for themselves at home
• D. A patient demonstrating symptoms of drug or alcohol withdrawal

Correct answer: C

Rationale: Patients with impaired awareness may exhibit symptoms such as being semiconscious, overfatigued, disoriented, confused, or demonstrating symptoms of drug or alcohol withdrawal. A patient who cannot care for themselves at home does not necessarily indicate impaired awareness, as this could be due to physical limitations or lack of support, rather than a cognitive deficit.

5. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.
