1. Which hormone, produced by the ovaries, is responsible for the development of the uterine lining during the menstrual cycle and supports early pregnancy?

A. Estrogen
B. Progesterone
C. Testosterone
D. Prolactin

Correct answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is a hormone produced by the ovaries that plays a crucial role in the menstrual cycle and early pregnancy. During the menstrual cycle, progesterone helps to prepare the uterine lining for a potential pregnancy by making it thick and vascularized. If fertilization occurs, progesterone continues to support the early stages of pregnancy by maintaining the uterine lining and preventing menstruation. Estrogen also plays a role in the menstrual cycle by stimulating the growth of the uterine lining, but progesterone is primarily responsible for maintaining the uterine environment suitable for implantation and supporting early pregnancy. Testosterone is a male sex hormone, while prolactin is a hormone involved in milk production after childbirth.

2. The urethra is the tube that carries urine from the bladder to the outside of the body. How does urine flow through the urethra?

A. Continuously
B. Only when the bladder is completely full
C. Under voluntary control of sphincter muscles
D. A combination of b) and c)

Correct answer: C

Rationale: The correct answer is C: "Under voluntary control of sphincter muscles." The urethra is the tube responsible for carrying urine from the bladder to the outside of the body. Urine flow through the urethra is not continuous but rather under voluntary control. The sphincter muscles, located at the opening of the bladder and urethra, help control the release of urine. This control allows individuals to regulate when and where they empty their bladder, providing a mechanism to prevent involuntary leakage of urine. Therefore, option C accurately describes how urine flows through the urethra.

3. 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

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.

4. What is the author's stance towards the idea of smart cities?

5. What property of a wave determines its speed in a given medium?

A. Amplitude

C. Frequency
D. Medium's properties

Correct answer: d

Rationale: The speed of a wave is determined by the properties of the medium it travels through.

6. What is kwashiorkor, a protein deficiency disease, characterized by?

A. Muscle wasting
B. Night blindness
C. Scurvy
D. Rickets

Correct answer: A

Rationale: Rationale: Kwashiorkor is a type of severe acute malnutrition caused by a deficiency of dietary protein. It is characterized by symptoms such as edema (swelling due to fluid retention), skin lesions, an enlarged liver with fatty infiltrates, and muscle wasting. Muscle wasting is a key feature of kwashiorkor due to the body breaking down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is a symptom of vitamin A deficiency, scurvy (option C) is caused by a lack of vitamin C, and rickets (option D) is a condition resulting from a deficiency of vitamin D, calcium, or phosphate.
