For a complete spinal injury, which statement is true?
- A. Some of the motor and sensory functions are lost
- B. Only the motor functions are lost
- C. Only the sensory functions are lost
- D. Both the motor and sensory functions are lost
Correct Answer: D
Rationale: The correct answer is D because in a complete spinal injury, both motor and sensory functions are lost below the level of the injury. This occurs due to the disruption of communication between the brain and the rest of the body. Choice A is incorrect as it implies that only some functions are lost, which is not the case in a complete injury. Choice B is incorrect because sensory functions are also affected in a complete spinal injury. Choice C is incorrect as it suggests that only sensory functions are lost, which is not true for a complete spinal injury.

Which of the following are major veins commonly used in parenteral cannulation?
- A. Basilic vein
- B. Femoral vein
- C. Subclavian vein
- D. Aorta
Correct Answer: D
Rationale: I'm sorry, but the correct answer provided (D: Aorta) is actually incorrect in this context. The major veins commonly used in parenteral cannulation are A: Basilic vein, B: Femoral vein, and C: Subclavian vein. The aorta is a major artery, not a vein, and is not typically used for parenteral cannulation due to its high pressure and risk of complications. It's important to understand the differences between veins and arteries when considering cannulation sites.
What action would a community health nurse take to address health disparities?
- A. Providing health education to individuals
- B. Advocating for policies that promote health equity
- C. Conducting community health assessments
- D. Offering free health screenings
Correct Answer: B
Rationale: The correct answer is B because advocating for policies that promote health equity addresses the root causes of health disparities at a systemic level, leading to sustainable change. Providing health education to individuals (A) is important but may not address underlying systemic issues. Conducting community health assessments (C) is a valuable tool but alone does not directly address health disparities. Offering free health screenings (D) may improve access to care but does not tackle the broader social determinants of health that contribute to disparities. Advocating for policies that promote health equity is the most effective way for a community health nurse to create lasting change and address health disparities comprehensively.
You are preparing a patient for surgery and completing the preoperative checklist. Which of the following is not typically part of the preoperative checklist?
- A. Assessing for allergies
- B. Conducting the Time Out
- C. Ensuring that informed consent is signed
- D. Ensuring that the history and physical examination have been completed
Correct Answer: B
Rationale: Step-by-step rationale:
1. Conducting the Time Out is typically part of the surgical safety checklist during the actual surgery, not the preoperative checklist.
2. Assessing for allergies is important to prevent adverse reactions during surgery.
3. Ensuring informed consent is signed is crucial for legal and ethical reasons.
4. Ensuring history and physical examination are completed helps in assessing the patient's health status before surgery.
Therefore, choice B is not typically part of the preoperative checklist, making it the correct answer.
Which best describes a community health assessment?
- A. A comprehensive evaluation of the health needs of a community
- B. An analysis of the effectiveness of health interventions
- C. A survey of individual health behaviors and outcomes
- D. A review of health care resources available in a community
Correct Answer: A
Rationale: Step 1: A community health assessment involves evaluating the overall health needs of a community, including social determinants and health disparities.
Step 2: It considers factors such as demographics, health behaviors, access to care, and environmental health.
Step 3: By conducting a comprehensive assessment, public health officials can identify priorities for intervention and allocate resources effectively.
Step 4: Option A aligns with the process of assessing community health comprehensively.
Summary: Options B, C, and D are incorrect because they focus on specific aspects (interventions, individual behaviors, and health care resources) rather than the holistic evaluation of a community's health needs.
What is the drug of choice for progressive multiple sclerosis?
- A. Ocrelizumab
- B. Dimethyl fumarate
- C. Teriflunomide
- D. Fluoroquinolones
Correct Answer: A
Rationale: The correct answer is A: Ocrelizumab. It is the drug of choice for progressive multiple sclerosis due to its proven efficacy in reducing disease progression and disability in clinical trials. Ocrelizumab specifically targets B cells, which play a key role in the pathogenesis of multiple sclerosis. Dimethyl fumarate (B) and Teriflunomide (C) are more commonly used for relapsing-remitting multiple sclerosis rather than progressive forms. Fluoroquinolones (D) are antibiotics and have no role in the treatment of multiple sclerosis.
