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

Correct Answer: C

Rationale: Neurogenic shock is characterized by hypotension and vasodilatation due to loss of sympathetic tone. The narrowed pulse pressure is not a classic characteristic but rather a sign of cardiogenic shock. Neurologic deficit is common in neurogenic shock due to the underlying neurological injury. Therefore, choice C is incorrect as it does not align with the typical features 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 medical treatment preferences in case they are unable to communicate their wishes. It includes instructions on life-sustaining treatments, organ donation, and healthcare proxy. Choice A, a will, is a legal document that outlines how a person's assets should be distributed after their death, not medical care preferences. Choice C, CPR, refers to cardiopulmonary resuscitation, a medical emergency procedure, not a legal document. Choice D, power of attorney, grants someone the legal authority to make decisions on behalf of another person, but it is not specific to medical care preferences.

Correct Answer: B

Rationale: The correct answer is B: Assessment. It is the first step in the nursing process because it involves gathering data about the patient's health status and identifying any potential issues. Assessment provides the foundation for the subsequent steps of diagnosis, planning, implementation, and evaluation. Diagnosis (A) comes after assessment to identify the patient's problems. Planning (D) follows diagnosis to set goals and develop a care plan. Evaluation (C) is the final step to assess the outcomes of the care provided. Assessment is crucial as it guides the nurse in making informed decisions and interventions based on the patient's needs.

Correct Answer: A

Rationale: Step 1: Health refers to the overall physical, mental, and social well-being of an individual, encompassing more than just the absence of disease. Step 2: Wellness, on the other hand, is a broader concept that includes health but also focuses on achieving a state of optimal well-being in various aspects of life. Step 3: Option A correctly distinguishes between health and wellness by stating that health is the absence of disease, while wellness encompasses physical, mental, and social well-being. Step 4: Options B, C, and D either incorrectly equate health with wellness or provide vague definitions that do not clearly differentiate between the two concepts. Summary: Option A is correct because it accurately defines health and wellness, while the other choices either conflate the two terms or provide incomplete or inaccurate descriptions.

Correct Answer: A

Rationale: The correct answer is A: One. Breaking any single link in the chain of infection is sufficient to prevent infection. The chain consists of six links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. By breaking any one link, such as practicing proper hand hygiene (mode of transmission), infection can be prevented. Choices B, C, and D are incorrect as they imply multiple links need to be broken, which is not necessary as breaking just one link disrupts the transmission of infection.
