1. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

• A. 4:00 PM
• B. 6:00 PM
• C. 8:00 PM
• D. 10:00 PM

Correct answer: B

Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep. Choice A (4:00 PM) is too early, not maintaining the 12-hour interval. Choice C (8:00 PM) aligns with the 12-hour interval but might be too close to bedtime, potentially causing sleep disruptions. Choice D (10:00 PM) is too late and exceeds the 12-hour interval.

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

• A. sagittal
• B. median
• C. frontal
• D. axial

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.

3. The nurse assisted the physician in removing the 'cast' from the patient's arm.

• A. Protective device
• B. Medicated sleeve
• C. Sling
• D. Bandage

Correct answer: A

Rationale: The correct answer is A: 'Protective device.' A 'cast' is a hard protective device used to support and immobilize a broken bone. It is not a 'medicated sleeve' (B), a 'sling' (C), or a 'bandage' (D), as these items serve different purposes in medical care.

4. What is the correct formula for iron III oxide?

• A. IO
• B. FeS
• C. Fe₂O₃
• D. OFe₂₃

Correct answer: C

Rationale: The correct formula for iron III oxide is Fe2O3. In this formula, Fe represents iron and O represents oxygen. Iron III oxide consists of two iron (Fe) ions combined with three oxygen (O) ions. Thus, the correct formula is Fe2O3. Choice A (IO) is incorrect as it does not represent the correct combination of iron and oxygen ions. Choice B (FeS) is incorrect as it represents iron sulfide, not iron III oxide. Choice D (OFe₂₃) is incorrect as it does not follow the correct chemical nomenclature for iron III oxide.

5. Which of the following is not a function of the skeletal system?

• A. Providing the shape and form of our bodies
• B. Supporting and protecting the body
• C. Producing blood
• D. Storing vitamins

Correct answer: C

Rationale: Producing blood is not a function of the skeletal system. Blood production primarily occurs in the bone marrow, which is found within the bones. The skeletal system provides the shape and form of our bodies, supports and protects the body, and stores minerals like calcium and phosphorus for various functions. Storing vitamins is not a primary function of the skeletal system, although some vitamins may play a role in bone health.
