1. He raised the issue on giving priority to patient needs. Which of the following offers the best

A. Assessing nursing needs and problems
B. Giving instructions on how nursing care needs are to be met
C. Controlling and evaluating the delivery of nursing care
D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

2. Which part of the brain is responsible for coordinating various sensory inputs, regulating sleep, and maintaining wakefulness?

A. Cerebrum
B. Hypothalamus
C. Medulla oblongata
D. Reticular formation

Correct answer: d

Rationale: The correct answer is D: Reticular formation. The reticular formation is a network of neurons located in the brainstem that plays a crucial role in regulating consciousness, arousal, and sleep-wake transitions. It receives sensory inputs from various parts of the body and helps coordinate these inputs to maintain wakefulness and alertness. While the cerebrum is responsible for higher cognitive functions and the hypothalamus regulates various physiological processes like body temperature and hunger, the reticular formation specifically focuses on integrating sensory information and controlling wakefulness.

3. Which of the following is a unit of measurement for energy?

A. Watt (W)
B. Joule (J)
C. Newton (N)
D. Kilogram (kg)

Correct answer: b

Rationale: Energy is measured in Joules (J) in the SI unit system.

4. A set of integers can be classified as positive, negative, or zero. Which of the following statements about multiplying positive and negative integers is ALWAYS true?

A. The product will always be positive.
B. The product will always be negative.
C. The product will depend on the specific positive and negative numbers used.
D. Positive and negative integers cannot be multiplied

Correct answer: B

Rationale: Rationale: When multiplying a positive integer by a negative integer, the product will always be negative. This is a fundamental rule of arithmetic. The sign of the product is determined by the rule that states that a positive number multiplied by a negative number results in a negative number. Therefore, the statement that the product will always be negative is always true when multiplying positive and negative integers.

5. What does the term "colligative property" refer to in solutions?

A. Properties that depend on the nature of the solute particles
B. Properties that depend on the concentration of solute particles
C. Properties that depend on the temperature of the solution
D. Properties that depend on the pressure of the solution

Correct answer: b

Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.

6. Which element is a good conductor of electricity but is not a metal?

A. Copper
B. Silver
C. Graphite
D. Gold

Correct answer: C

Rationale: While metals are known for their conductivity, some non-metals like graphite also exhibit this property due to their unique electronic structure
