1. What is the structure that connects the ovary to the uterus in the female reproductive system?

A. Urethra
B. Fallopian tube
C. Vagina
D. Cervix

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes play a crucial role in the fertilization process by providing a pathway for the egg to travel from the ovary to the uterus. The urethra (A) is a structure that carries urine from the bladder out of the body and is not directly involved in the reproductive system. The vagina (C) is the canal that connects the external genitals to the cervix and is not the structure that connects the ovary to the uterus. The cervix (D) is the lower part of the uterus that connects to the vagina and does not connect the ovary to the uterus.

2. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

A. Skeletal muscle
B. Smooth muscle
C. Cardiac muscle
D. All of the above

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.

3. Acne vulgaris, commonly known as acne, is primarily caused by

A. Dry skin (Dry skin can worsen acne but isn't the primary cause)
B. Clogged pores and excess oil production
C. Bacterial infection alone (Bacteria play a role but not the sole cause)
D. Vitamin deficiency

Correct answer: B

Rationale: The correct answer is B: 'Clogged pores and excess oil production.' Acne vulgaris, or acne, is primarily caused by a combination of factors including excess sebum (oil) production by the skin's sebaceous glands and the accumulation of dead skin cells, leading to clogged pores. This environment provides a breeding ground for acne-causing bacteria, contributing to inflammation and the formation of pimples. While factors like dry skin, bacterial infections, and even vitamin deficiencies can exacerbate acne, they are not the primary cause. Thus, B is the most accurate option for the primary cause of acne.

4. What is the main function of the large intestine?

A. Break down food
B. Absorb water
C. Secrete digestive enzymes
D. Store waste

Correct answer: B

Rationale: The correct answer is B: "Absorb water." The main function of the large intestine is to absorb water and electrolytes from the undigested food material that passes through it. This helps in the formation of solid waste or feces, which is then stored in the rectum until it is eliminated from the body. Breaking down food primarily occurs in the small intestine, while the large intestine focuses on reabsorbing water to prevent dehydration. Secreting digestive enzymes is mainly done by the pancreas and liver, not the large intestine.

5. Identify the bone with the greatest length in the human body.

A. Femur (Thigh bone)
B. Humerus (Upper arm bone)
C. Tibia (Shin bone)
D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.

6. She wants to ensure that every task is carried out as planned. Which of the following tasks is

A. Instructing the members of the standards committee to prepare policies
B. Reviewing the existing policies of the hospital
C. Evaluating the credentials of all nursing staff
D. Checking if activities conform to schedule

Correct answer: C

Rationale: The correct answer is C because evaluating the credentials of all nursing staff is essential to ensuring that the right individuals are in place to carry out tasks effectively. This task directly contributes to maintaining a high standard of performance and ensuring that the team is qualified for their roles. In contrast, the other options focus on policies, reviews, and schedules, which are important but do not directly address the qualifications and capabilities of the staff responsible for task execution.
