1. What is the name of a condition where the heart rate is 118 beats per minute (bpm)?

• A. Tachycardia
• B. Apnea
• C. Bradycardia
• D. Tachypnea

Correct answer: A

Rationale: The correct answer is A: Tachycardia. Tachycardia is a condition characterized by a heart rate that exceeds the normal resting rate, typically above 100 bpm. In this case, a heart rate of 118 bpm falls within the range of tachycardia. Apnea (choice B) refers to the temporary cessation of breathing, not related to heart rate. Bradycardia (choice C) is a condition of an abnormally slow heart rate, opposite of the given heart rate. Tachypnea (choice D) is an abnormally rapid breathing rate, not related to heart rate.

2. Which term refers to a position farther from the midline of the body? For example, the little toe is lateral to the big toe on the same foot.

• A. Lateral
• B. Medial
• C. Proximal
• D. Distal

Correct answer: A

Rationale: The correct answer is A: Lateral. Lateral refers to a position farther away from the midline of the body. In the example provided, the little toe is indeed lateral to the big toe on the same foot. This is in contrast to 'medial,' which means closer to the midline. 'Proximal' refers to a position closer to the point of attachment or the trunk of the body, while 'distal' refers to a position farther from the point of attachment or the trunk of the body.

3. Identify the spectator ions in the reaction: 2KCl + Pb(NO3)2 → 2KNO3 + PbCl2.

• A. K+ and NO3-
• B. K+ and Cl-
• C. Pb2+ and NO3-
• D. Pb2+ and Cl-

Correct answer: B

Rationale: - In the reaction, potassium ions (K+) and chloride ions (Cl-) are present on both sides of the equation. They are not involved in the formation of the products and remain unchanged. - Lead ions (Pb2+) and nitrate ions (NO3-) are involved in the formation of the products potassium nitrate (KNO3) and lead(II) chloride (PbCl2). - Therefore, the spectator ions in this reaction are K+ and Cl-.

4. Which of the following is part of the central nervous system?

• A. Spinal cord
• B. Peripheral nerves
• C. Brainstem
• D. Cerebellum

Correct answer: A

Rationale: The correct answer is A: Spinal cord. The central nervous system comprises the brain and spinal cord. The spinal cord plays a crucial role in transmitting information between the brain and the body. Choices B, C, and D are not part of the central nervous system. Peripheral nerves belong to the peripheral nervous system, whereas the brainstem and cerebellum are components of the brain, distinct from the central nervous system.

5. Which part of the hair is not attached to the follicle?

• A. Bulb
• B. Root
• C. Shaft
• D. Strand

Correct answer: C

Rationale: The correct answer is C, 'Shaft.' The hair shaft is the part of the hair that extends above the skin surface and is not attached to the follicle. The bulb and root are parts that are connected to the follicle as they are located below the skin surface and play a role in hair growth. The strand, on the other hand, refers to a single hair fiber and is not a distinct part of the hair anatomy.
