1. Which of the following is NOT a common route of transmission for a sexually transmitted infection (STI)?

• A. Unprotected sexual contact
• B. Sharing contaminated needles
• C. Deep kissing
• D. Mother to child during childbirth

Correct answer: C

Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. Although some STIs can be transmitted through saliva, deep kissing is not a primary mode of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.

2. What is the function of the esophagus in the digestive system?

• A. To absorb nutrients
• B. To transport food from the mouth to the stomach
• C. To break down food
• D. To absorb water

Correct answer: B

Rationale: The esophagus functions to transport food from the mouth to the stomach through a process called peristalsis, which involves a series of muscle contractions that push the food downward along the digestive tract. Absorbing nutrients (Choice A) is typically done in the small intestine, breaking down food (Choice C) is primarily the role of the stomach and small intestine, and absorbing water (Choice D) mainly occurs in the large intestine.

3. What does the term 'electron configuration' refer to in relation to an atom?

• A. The arrangement of electrons in an atom's orbitals.
• B. The number of protons in an atom's nucleus.
• C. The number of neutrons in an atom's nucleus.
• D. The number of electrons in an atom's valence shell.

Correct answer: A

Rationale: The electron configuration of an atom refers to the arrangement of electrons in the atom's orbitals. This arrangement determines the atom's chemical properties and behavior. The number of protons in an atom's nucleus (option B) is known as the atomic number, which defines the element. The number of neutrons in an atom's nucleus (option C) contributes to the atom's mass number. The number of electrons in an atom's valence shell (option D) is important for understanding the atom's reactivity and bonding behavior, but the electron configuration specifically refers to how electrons are distributed among the different orbitals in an atom.

4. Which of the following statements is correct based on anatomical terms?

• A. The shoulder joint is proximal to the neck.
• B. The elbow joint is superior to the shoulder.
• C. The thoracic vertebrae are superior to the cervical vertebrae.
• D. The thumb is on the lateral aspect of the hand.

Correct answer: D

Rationale: Option D is the correct answer based on anatomical terms. The thumb is indeed located on the lateral aspect of the hand, following anatomical positioning. The terms 'proximal,' 'superior,' and 'inferior' are used in relation to the center of the body or a specific point of reference, while 'lateral' and 'medial' describe positions further away or closer to the midline of the body. Therefore, the thumb being on the lateral side of the hand is an accurate anatomical description. Choices A, B, and C are incorrect because they do not align with anatomical terminology. In anatomical terms, 'proximal' refers to a position closer to the center of the body, 'superior' indicates a position above or higher than another part, and 'inferior' signifies a position below or lower than another part. The shoulder joint is distal to the neck, the elbow is inferior to the shoulder, and the cervical vertebrae are superior to the thoracic vertebrae.

5. Which division of the autonomic nervous system is responsible for the 'rest and digest' response, promoting relaxation and conservation of energy?

• A. Sympathetic nervous system
• B. Parasympathetic nervous system
• C. Somatic nervous system
• D. Central nervous system

Correct answer: B

Rationale: The correct answer is B: Parasympathetic nervous system. The parasympathetic nervous system is responsible for the 'rest and digest' response, promoting relaxation, conserving energy, and facilitating activities like digestion and lowering heart rate. The sympathetic nervous system, which is not the correct answer, triggers the 'fight or flight' response, preparing the body for stressful situations by increasing heart rate, dilating airways, and releasing adrenaline. The somatic nervous system (choice C) controls voluntary movements, not the autonomic functions related to 'rest and digest.' The central nervous system (choice D) includes the brain and spinal cord and is not specifically involved in the autonomic regulation of bodily functions like the 'rest and digest' response.
