1. Which parts of the heart are separated by the mitral valve?

• A. Left atrium and right atrium
• B. Right atrium and right ventricle
• C. Left ventricle and right ventricle
• D. Left atrium and left ventricle

Correct answer: D

Rationale: The mitral valve, also known as the bicuspid valve, separates the left atrium and the left ventricle of the heart. Its primary function is to prevent the backflow of blood from the left ventricle to the left atrium during the heart's contraction. Therefore, option D, 'Left atrium and left ventricle,' is the correct answer. Choices A, B, and C are incorrect because they do not represent the parts separated by the mitral valve.

2. Select the word in the following sentence that is not used correctly. On departing, the patient complimented her therapist and counselor.

• A. departing
• B. complimented
• C. therapist
• D. counselor

Correct answer: C

Rationale: The word 'therapist' in the sentence is used correctly. However, the word 'councilor' is misspelled and should be 'counselor' to refer to a mental health professional providing therapy services. The correct term should have an 's' after 'counselor,' making it 'counselor' instead of 'councilor.' Therefore, the word 'councilor' is the one not used correctly in the sentence.

3. What is the primary function of the nervous system?

• A. To transmit signals and coordinate body activities
• B. To fight infections
• C. To produce hormones
• D. To regulate body temperature

Correct answer: A

Rationale: The primary function of the nervous system is to transmit signals and coordinate body activities. It controls and regulates body functions by sending and receiving signals between different parts of the body, enabling responses to internal and external stimuli. This intricate network allows for communication between the brain, spinal cord, and the rest of the body, ultimately facilitating movement, sensation, thoughts, and various bodily functions. Choices B, C, and D are incorrect as they do not represent the primary function of the nervous system. Fighting infections is primarily the role of the immune system, producing hormones is the function of the endocrine system, and regulating body temperature involves mechanisms of thermoregulation within the body, not directly controlled by the nervous system.

4. The word watchdog as used in the second paragraph of the passage can best be defined as ___________.

• A. companion
• B. guard
• C. manager
• D. punisher

Correct answer: B

Rationale: In this context, "watchdog" refers to a guard or overseer, specifically relating to Lifewings Partners’ mission of ensuring safety and preventing medical errors. The organization acts as a monitor in healthcare settings, which aligns with the definition of a watchdog, confirming that option B is correct.

5. Which of the following structures is part of both the male reproductive system and the urinary system?

• A. Bladder
• B. Urethra
• C. Prostate
• D. Seminal Vesicle

Correct answer: B

Rationale: The urethra is the correct answer as it is a structure shared by both the male reproductive and urinary systems. It functions as a conduit for both urine from the bladder and semen from the reproductive system, making it a crucial component of both systems. The bladder (Choice A) is solely part of the urinary system, storing urine. The prostate (Choice C) and seminal vesicle (Choice D) are structures specific to the male reproductive system, involved in producing and secreting components of semen.
