1. What number is represented by the Roman Numerals XLIV?

• A. 34
• B. 54
• C. 44
• D. 24

Correct answer: C

Rationale: In Roman numerals, XL represents 40, and IV represents 4. When XL (40) is combined with IV (4), it forms XLIV, which corresponds to the number 44. Therefore, the correct answer is 44. Choice A (34) is incorrect as it does not consider the value of XL and IV. Choice B (54) is incorrect as it miscalculates the value of XL. Choice D (24) is incorrect as it does not account for the value of XL.

2. How is the plasma membrane arranged?

• A. In a single layer made of proteins
• B. In a double layer made of proteins
• C. In a single layer of phospholipids
• D. In a double layer of phospholipids

Correct answer: D

Rationale: The plasma membrane is arranged in a double layer of phospholipids, known as a phospholipid bilayer. This structure consists of two layers of phospholipid molecules with hydrophilic heads facing the exterior and hydrophobic tails facing the interior, providing a semipermeable barrier for the cell. Choice A is incorrect because the plasma membrane is not made of a single layer of proteins. Choice B is incorrect as the double layer is composed of phospholipids, not proteins. Choice C is incorrect as the plasma membrane is not made of a single layer of phospholipids but rather a double layer.

3. Which structure might be described as a core of nucleic acid surrounded by a protein coat?

• A. RNA
• B. Virus
• C. Blue-green alga
• D. Saprophyte

Correct answer: B

Rationale: A virus can be described as a core of nucleic acid (either RNA or DNA) surrounded by a protein coat, known as a capsid. This structure distinguishes viruses from other microorganisms such as blue-green algae (Cyanobacteria), fungi known as saprophytes, or individual RNA molecules. Viruses depend on a host cell to replicate and are considered non-living entities due to their inability to carry out metabolic functions independently.

4. After treatment, his PROGNOSIS was excellent. What does the term PROGNOSIS refer to?

• A. Compliance
• B. Range of motion
• C. Expected outcome
• D. Conclusion

Correct answer: C

Rationale: The term 'PROGNOSIS' refers to the expected outcome or likelihood of recovery after a specific treatment or illness. In this context, the word 'PROGNOSIS' directly relates to the expected outcome following the treatment, making choice C - Expected outcome - the correct answer. Choices A, B, and D are incorrect because 'Compliance' refers to following instructions, 'Range of motion' relates to the extent of movement in a joint, and 'Conclusion' is a summary or final decision, none of which captures the meaning of 'PROGNOSIS.'

5. What does Distended mean?

• A. Shrunken
• B. Enlarged or expanded from pressure
• C. Collapsed
• D. Constricted

Correct answer: B

Rationale: Distended means enlarged or expanded from pressure. The term 'shrunken' (Choice A) means reduced in size, 'collapsed' (Choice C) means fallen in or disintegrated, and 'constricted' (Choice D) means narrowed or tightened. Therefore, the correct answer is B.
