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. Certain medications can suppress the immune system to treat autoimmune diseases or prevent organ rejection after transplants. What is a potential risk associated with immunosuppressive drugs?

A. Increased risk of developing allergies
B. Increased susceptibility to infections
C. Both a and b
D. Neither a nor b

Correct answer: C

Rationale: The correct answer is C: 'Both a and b.' Immunocompromised individuals, who take immunosuppressive drugs, are at an increased risk of developing allergies due to the altered immune response. Additionally, these drugs suppress the immune system's ability to fight off infections, making individuals more susceptible to various pathogens. Therefore, both increased risk of developing allergies and increased susceptibility to infections are potential risks associated with immunosuppressive drugs, making option C the correct choice.

3. Which statement accurately describes the electron cloud model of the atom?

A. Electrons precisely orbit the nucleus in defined paths.
B. Electrons occupy specific energy levels around the nucleus with varying probabilities.
C. Electrons are clustered tightly within the nucleus.
D. Electrons move randomly throughout the entire atom.

Correct answer: B

Rationale: Electrons occupy specific energy levels around the nucleus with varying probabilities. The electron cloud model depicts electrons existing in distinct energy levels, not fixed orbits, with probabilities of finding them in specific regions.

4. What is the main function of transition words and phrases in writing?

A. To add unnecessary embellishments and fluff.
B. To emphasize specific words or phrases in the text.
C. To connect ideas smoothly and guide the reader's flow.
D. To introduce opposing viewpoints and counterarguments.

Correct answer: C

Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.

5. Which organelle is responsible for breaking down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks?

A. Golgi apparatus
B. Mitochondria
C. Lysosomes
D. Endoplasmic reticulum

Correct answer: C

Rationale: Rationale: Lysosomes are membrane-bound organelles containing digestive enzymes that break down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks. These enzymes help in the process of intracellular digestion and recycling of cellular components. The Golgi apparatus is involved in processing and packaging proteins for secretion or for use within the cell. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism.

6. Which of the following is the primary function of the cell membrane?

A. To provide structural support for the cell
B. To transport substances in and out of the cell
C. To synthesize proteins and lipids
D. To store genetic material

Correct answer: B

Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.
