1. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

2. Which hormone is involved in regulating the sleep-wake cycle?

Correct answer: B

Rationale: The correct answer is B: Melatonin. Melatonin, produced by the pineal gland, is the hormone involved in regulating the sleep-wake cycle. It plays a crucial role in signaling the body that it is time to sleep and is influenced by light exposure. Melatonin levels typically rise in the evening, promoting sleep, and decrease in the morning, helping in waking up. Choice A, Insulin, is involved in regulating blood sugar levels, not the sleep-wake cycle. Choice C, Cortisol, is a stress hormone that helps regulate metabolism and immune response but is not primarily involved in the sleep-wake cycle. Choice D, Thyroxine, is a hormone produced by the thyroid gland that regulates metabolism, growth, and development, but it is not directly involved in regulating the sleep-wake cycle.

3. Which of the following statements is anatomically correct?

Correct answer: C

Rationale: The term 'proximal' refers to a body part being closer to the center of the body or a point of reference. In this case, the hip is closer to the center of the body compared to the knee, which makes the statement anatomically correct. Choice A is incorrect as the knee is proximal to the ankle. Choice B is incorrect as the heart is superior to the diaphragm. Choice D is incorrect as the elbow is proximal to the wrist.

4. How might vitamin D deficiency present?

Correct answer: D

Rationale: Vitamin D deficiency can present as crooked bones in children due to a condition called rickets. This is because vitamin D plays a crucial role in calcium absorption and bone health. Inadequate levels of vitamin D can lead to soft and weak bones, resulting in skeletal deformities such as bow legs or knock knees. Choices A, B, and C are incorrect as bleeding gums are more commonly associated with vitamin C deficiency (scurvy), swollen extremities could be a sign of various conditions like edema, and red patches are not typically a direct manifestation of vitamin D deficiency.

5. The coronal plane of the body may also be called the ___________ plane.

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.
