1. The phrase "disruptions to ecosystems" refers to

• A. Minor inconveniences experienced by plant and animal species due to changing weather patterns.
• B. Significant changes in ecological relationships and imbalances in populations and food webs.
• C. The aesthetic alteration of landscapes due to melting glaciers and deforestation.
• D. The economic losses suffered by industries relying on natural resources affected by climate change.

Correct answer: B

Rationale: The phrase suggests profound impacts on ecological balance and species interactions, aligning with B.

2. What is the absolute value of -7?

• A. 49
• B. 17
• C. 7
• D. 14

Correct answer: A

Rationale: Absolute value refers to the non-negative distance of a number from zero. Regardless of being positive or negative, 7 is its distance from zero.

3. Which of the following is an example of aseptic technique?

• A. Washing hands with soap and water before surgery
• B. Coughing into your elbow
• C. Sharing a stethoscope without cleaning
• D. Leaving a wound dressing exposed

Correct answer: A

Rationale: Rationale: Aseptic technique refers to practices that help prevent the introduction of harmful microorganisms into a sterile environment. Washing hands with soap and water before surgery is an essential component of aseptic technique as it helps reduce the number of microorganisms on the hands, decreasing the risk of introducing pathogens into the surgical site. Coughing into your elbow is a good hygiene practice to prevent the spread of respiratory infections but is not specifically related to aseptic technique. Sharing a stethoscope without cleaning can introduce microorganisms from one patient to another, compromising aseptic conditions. Leaving a wound dressing exposed can lead to contamination and infection, which is contrary to aseptic technique.

4. The involuntary reflex arc that withdraws your hand from a hot object involves the:

• A. Central nervous system only
• B. Peripheral nervous system only
• C. Both CNS and PNS
• D. Sensory neurons only

Correct answer: C

Rationale: The correct answer is C: 'Both CNS and PNS'. This is because the reflex arc involves both the central nervous system (CNS) and the peripheral nervous system (PNS). The sensory neurons in the PNS detect the stimulus (hot object), then send signals to the spinal cord in the CNS. The spinal cord processes the information and immediately sends a motor response signal back out through the PNS to move the hand away from the hot object. This rapid and involuntary response demonstrates the coordination between the CNS and PNS in executing the reflex arc.

5. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?

• A. Insulin
• B. Glucagon
• C. Estrogen
• D. Testosterone

Correct answer: A

Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.

6. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

• A. Organizational structure
• B. Policy
• C. Job description
• D. Manual of procedures

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.
