1. 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.'

2. What is a muscular enlarged pouch or sac that lies slightly to the left and is used for the temporary storage of food?

• A. Gallbladder
• B. Urinary bladder
• C. Stomach
• D. Lungs

Correct answer: C

Rationale: The correct answer is the stomach. The stomach is a muscular organ located slightly to the left in the abdominal cavity. It serves as a temporary storage site for food where it is mixed with digestive enzymes and acids to begin the process of digestion. The gallbladder (Choice A) is not involved in food storage; it stores bile produced by the liver. The urinary bladder (Choice B) is part of the urinary system and stores urine. The lungs (Choice D) are responsible for respiration, not food storage.

3. Which of the following is the correct meaning of CBR?

• A. Cardiac Board Room
• B. Complete Bathroom
• C. Complete Bed Rest
• D. Complete Board Room

Correct answer: C

Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.

4. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

5. How many liters are equal to 1800 ml?

• A. 1.8
• B. 18000
• C. 180
• D. 2800

Correct answer: A

Rationale: To convert milliliters (ml) to liters, divide by 1000 since 1 liter is equal to 1000 ml. Therefore, 1800 ml is equal to 1800/1000 = 1.8 liters. Choice A (1.8) is correct. Choice B (18000) is incorrect as it equates to 18000 liters, not 1.8 liters. Choice C (180) is incorrect as it represents 180 liters, not 1.8 liters. Choice D (2800) is incorrect as it does not reflect the conversion of 1800 ml to liters.
