1. A patient who is heedless is ___________.

• A. unlucky
• B. careless
• C. no longer in care
• D. hard of hearing

Correct answer: B

Rationale: Someone who is heedless is not paying attention or being cautious. Therefore, a patient who is heedless can be described as careless, as they may not be taking proper care or paying attention to important things that affect their well-being. Choice A, 'unlucky,' is incorrect as being heedless is not related to luck. Choice C, 'no longer in care,' is incorrect as it does not accurately reflect the meaning of heedless. Choice D, 'hard of hearing,' is unrelated to the concept of being heedless.

2. What does the word UBIQUITOUS mean?

• A. Widespread
• B. Miniscule
• C. Invalid
• D. Unit

Correct answer: A

Rationale: The word UBIQUITOUS means something that is found everywhere or is very common. Therefore, the correct meaning for ubiquitous is 'widespread'. 'Miniscule' means very small, 'invalid' means not valid or acceptable, and 'unit' refers to a single entity or component, making them incorrect choices in the context of the word ubiquitous.

3. In this passage, which of these is not mentioned as a possible sign of heat exhaustion?

• A. Dizziness

4. What is the product of the decomposition of water?

• A. Hydrogen and oxygen
• B. Carbon dioxide
• C. Nitrogen and hydrogen
• D. Methane

Correct answer: A

Rationale: The correct answer is A: Hydrogen and oxygen. When water undergoes decomposition, it breaks down into hydrogen and oxygen gases through a process known as electrolysis. This reaction is represented by 2H₂O → 2H₂ + O₂. Choice B, carbon dioxide, is incorrect as it is not a product of water decomposition. Choice C, nitrogen and hydrogen, is incorrect as water decomposes into hydrogen and oxygen, not nitrogen. Choice D, methane, is incorrect as methane is not a product of water decomposition.

5. Which organelle in the cell contains the genetic material?

• A. Ribosome
• B. Nucleus
• C. Mitochondria
• D. Endoplasmic reticulum

Correct answer: B

Rationale: The correct answer is B, Nucleus. The nucleus is the organelle in the cell that contains the genetic material (DNA). DNA within the nucleus determines the cell's functions and characteristics, making it essential for cell function and replication. Choice A, Ribosome, is responsible for protein synthesis, not genetic material storage. Choice C, Mitochondria, produces energy but does not contain the genetic material. Choice D, Endoplasmic reticulum, is involved in protein synthesis and lipid metabolism but does not house the genetic material.
