You are called to assist a 20-year-old male for a severe headache. On-scene, you learn the patient was involved in an accident that caused a potential closed head injury. However, at the time of the accident, the patient refused EMS care, stating he felt fine. Today, he is experiencing headache, confusion, and visual disturbances. Which of the following injuries is most likely to cause this type presentation?
- A. Coup-contra-coup injury
- B. Diffuse axonal injury
- C. Subdural hematoma
- D. Epidural hematoma
Correct Answer: C
Rationale: Rationale: The correct answer is C: Subdural hematoma. Subdural hematoma is a collection of blood between the dura mater and arachnoid mater of the brain, often caused by head trauma. Symptoms include headache, confusion, and visual disturbances, which align with the patient's presentation. Subdural hematomas can develop gradually after a head injury, leading to delayed symptoms.
Other choices:
A: Coup-contra-coup injury - This injury involves the brain hitting the skull on both sides due to acceleration-deceleration forces, but it typically presents with focal neurological deficits rather than the diffuse symptoms described.
B: Diffuse axonal injury - This injury involves widespread damage to nerve fibers in the brain, leading to coma or altered consciousness rather than confusion and visual disturbances.
D: Epidural hematoma - This injury is a collection of blood between the skull and dura mater, typically causing rapid deterioration in mental status and focal neurological deficits, not confusion
Moving a body part away from the body is called
- A. Abduction
- B. Addition
- C. Adduction
- D. Ambulation
Correct Answer: A
Rationale: The correct answer is A: Abduction. Abduction refers to moving a body part away from the body's midline. This action is commonly seen in movements like raising your arm sideways. It is important to differentiate it from the other choices. Addition (B) is not a term used in anatomy for body movements. Adduction (C) is the opposite of abduction, involving bringing a body part towards the body's midline. Ambulation (D) refers to the act of walking and is not related to moving body parts away from the body.

Which of the following is a function of the integumentary system?
- A. Regulates hormone levels in the body
- B. Prevents the loss of too much water
- C. Allows the body to move
- D. Provides an environment for the development of a fetus
Correct Answer: B
Rationale: The correct answer is B: Prevents the loss of too much water. The integumentary system includes the skin, which acts as a barrier to prevent excessive water loss from the body. This is essential for maintaining proper hydration levels and overall health. Choices A, C, and D are incorrect because regulating hormone levels, allowing body movement, and providing an environment for fetal development are functions of other body systems like the endocrine, muscular, and reproductive systems, respectively.
A nursing assistant must usually take the state test within ______ months after training.
- A. 6
- B. 12
- C. 24
- D. 36
Correct Answer: A
Rationale: The correct answer is A: 6 months. This is because most states require nursing assistants to take the state test within 6 months after completing their training to ensure they have recent knowledge and skills. Choice B, 12 months, is too long of a gap for testing after training. Choice C, 24 months, and choice D, 36 months, are even longer durations, which would not be beneficial for assessing the competency of nursing assistants in a timely manner. Therefore, choice A is the most appropriate timeframe for taking the state test after training.
