Neurogenic shock has all of the following classic characteristics except which one:

Correct Answer: C

Rationale: Neurogenic shock results from disruption of sympathetic nervous system control, leading to vasodilation and subsequent hypotension. Choice C, "Narrowed pulse pressure," is incorrect because neurogenic shock typically presents with widened pulse pressure due to the loss of sympathetic tone on arterial vessels. Therefore, the correct answer is C. Choices A, B, and D are all classic characteristics of neurogenic shock.

Correct Answer: B

Rationale: The correct answer is B: Advance directive. An advance directive is a legal document that allows an individual to specify their preferences for medical treatment in case they become unable to communicate or make decisions. This includes instructions for end-of-life care, life-sustaining treatments, and other healthcare choices. It is different from a will (A) which dictates how assets are distributed after death, CPR (C) which is a medical procedure to revive a person in cardiac arrest, and Power of Attorney (D) which grants someone the authority to make legal decisions on behalf of another person.

Correct Answer: B

Rationale: The correct answer is B: Assessment. In the nursing process, assessment is the first step where the nurse collects data about the patient's health status, including physical, emotional, social, and environmental factors. This information is crucial for identifying the patient's needs and developing a care plan. Diagnosis (A) comes after assessment, where the nurse analyzes the collected data. Planning (D) follows diagnosis and involves setting goals and outlining interventions. Evaluation (C) is the final step to assess the effectiveness of the care plan. Therefore, assessment is the initial step in the nursing process to gather relevant information for providing optimal patient care.

Correct Answer: A

Rationale: The correct answer is A because health refers to the absence of disease, while wellness encompasses physical, mental, and social well-being. Health is more focused on the biological aspect, whereas wellness is a holistic concept. Choice B is incorrect as wellness is not just about balance. Choice C is incorrect as health is not merely the absence of disease. Choice D is incorrect as health and wellness have distinct meanings.

Correct Answer: A

Rationale: The correct answer is A: One. To prevent infection, breaking any single link in the chain of infection is sufficient. This could be eliminating the infectious agent, interrupting the mode of transmission, protecting the portal of entry, or strengthening the host's immune response. Explanation: 1. Breaking any one link prevents the transmission of the infectious agent. 2. For example, washing hands (interruption of the mode of transmission) can prevent the spread of infections. 3. By focusing on one key aspect, the entire chain is disrupted effectively. Summary: Choice A is correct because breaking one link in the chain of infection is necessary and sufficient to prevent infection. Choices B, C, and D are incorrect because they suggest a need to break multiple links, which is not always required for infection prevention.
