1. Which of the following are major veins commonly used in parenteral cannulation?

• A. Basilic vein
• B. Femoral vein
• C. Subclavian vein
• D. Aorta

Correct Answer: D

Rationale: The aorta is not a vein; it is the main artery in the body that carries oxygenated blood from the heart to the rest of the body. In parenteral cannulation, major veins like the basilic vein, femoral vein, and subclavian vein are typically used for access. Therefore, the correct answer is the aorta, as it is an artery and not a vein used for cannulation.

2. Which of the following is an indication for tracheostomy?

• A. Drainage of pleural effusion
• B. Hemorrhage
• C. Infections
• D. Acute respiratory failure

Correct Answer: D

Rationale: Tracheostomy is a surgical procedure where an incision is made in the windpipe to help with breathing. Acute respiratory failure, which can occur due to various reasons such as upper airway obstruction, is a common indication for tracheostomy. While drainage of pleural effusion, hemorrhage, and infections may require medical intervention, they are not direct indications for a tracheostomy like acute respiratory failure.

3. What procedure is performed prior to a blood transfusion to detect incompatibilities?

• A. Grouping and crossmatching
• B. Complete blood count
• C. D-dimer test
• D. Blood clotting test

Correct Answer: Grouping and crossmatching

Rationale: Grouping and crossmatching is the procedure performed prior to a blood transfusion to determine the blood type and identify any potential incompatibilities between the donor and recipient. This process involves testing the recipient's blood for ABO and Rh antigens and crossmatching it with the donor's blood to ensure compatibility and prevent adverse reactions during the transfusion. Complete blood count, D-dimer test, and blood clotting test are other laboratory tests that serve different purposes and are not specifically done to detect incompatibilities prior to blood transfusion.

4. Which of the following is not a therapeutic indication of bone marrow puncture?

• A. Analgesia
• B. Antibiotics
• C. Anaesthesia
• D. Inflammation

Correct Answer: A

Rationale: Bone marrow puncture is not typically performed for analgesia purposes. It is primarily done for diagnostic or therapeutic reasons, such as obtaining a sample for testing, administering medications like antibiotics, providing anesthesia during the procedure, or treating conditions related to inflammation. Analgesia, which refers to pain relief, is not a direct therapeutic indication for bone marrow puncture.

5. Which fluid is used in the management of gastrointestinal tract (GIT) loss and burns?

• A. Ringer’s lactate
• B. Normal saline
• C. Dextrose
• D. Blood

Correct Answer: Ringer’s lactate

Rationale: Ringer’s lactate is the preferred fluid for managing gastrointestinal tract (GIT) losses and burns due to its balanced electrolyte composition. It helps replace lost fluids and electrolytes, making it an ideal choice for resuscitation in such scenarios. Normal saline is commonly used for volume resuscitation but may not be the best choice for these specific conditions. Dextrose is a source of glucose and is not typically used as the primary fluid for GIT losses and burns. Blood transfusion is indicated for specific situations like severe hemorrhage or anemia but is not the primary fluid for GIT losses and burns.
