Medical Knowledge Clinical Procedures 1 — Questions and Answers
Question 1: What is the correct technique for measuring blood pressure?
- Place cuff over clothing above heart level
- Use a properly sized cuff on the bare arm at heart level with the patient seated (Correct answer)
- Always use the smallest available cuff
- Place cuff on the forearm
Correct answer: Use a properly sized cuff on the bare arm at heart level with the patient seated
Accurate blood pressure measurement requires a properly sized cuff applied to the bare arm at heart level while the patient is seated and resting.
Question 2: What does a 12-lead ECG primarily assess?
- Blood oxygen levels
- Electrical activity of the heart (Correct answer)
- Brain wave patterns
- Skeletal muscle function
Correct answer: Electrical activity of the heart
A 12-lead ECG records the heart's electrical activity from 12 different angles to diagnose arrhythmias, ischemia, and infarction.
Question 3: What is the correct order for donning PPE?
- Mask, gown, goggles, gloves
- Gown, mask/respirator, eye protection, gloves (Correct answer)
- Gloves, gown, mask, goggles
- Goggles, gloves, gown, mask
Correct answer: Gown, mask/respirator, eye protection, gloves
The correct PPE donning order is gown first, then mask/respirator, then eye protection, then gloves to minimize self-contamination.
Question 4: Why is a tourniquet applied before venipuncture?
- To prevent bleeding after needle insertion
- To clean the insertion site
- To engorge the vein for easier access before needle insertion (Correct answer)
- To measure blood pressure simultaneously
Correct answer: To engorge the vein for easier access before needle insertion
A tourniquet applied 3–4 inches above the site distends the vein by impeding venous return, making it easier to locate and puncture.
Question 5: What is the purpose of an indwelling Foley catheter?
- Administer IV fluids
- Drain urine continuously from the bladder (Correct answer)
- Measure central venous pressure
- Deliver enteral nutrition
Correct answer: Drain urine continuously from the bladder
A Foley catheter is an indwelling urinary catheter that continuously drains urine from the bladder when the patient cannot void.
Question 6: Which are accepted sites for intramuscular injection in adults?
- Upper inner arm only
- Deltoid, vastus lateralis, or ventrogluteal muscle (Correct answer)
- Lower abdomen only
- Behind the knee
Correct answer: Deltoid, vastus lateralis, or ventrogluteal muscle
Common IM injection sites include the deltoid, vastus lateralis, and ventrogluteal muscles, selected based on drug volume and patient factors.
