1. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

2. Which of the following differentiates ulcerative colitis from Crohn's disease?

• A. Crohn's disease primarily affects the left colon and rectum, while ulcerative colitis most often affects the right colon and distal ileum.
• B. Crohn's disease presents with shallow ulcerations, whereas ulcerative colitis presents with a cobblestone appearance of the mucosal lining.
• C. The extent of involvement is noncontiguous and segmented with Crohn's disease, whereas it is contiguous and diffuse with ulcerative colitis.
• D. Crohn's disease has primarily mucosal involvement, whereas it is transmural with ulcerative colitis.

Correct answer: C

Rationale: The correct answer is C. Crohn's disease is characterized by noncontiguous, segmented involvement, meaning it can affect different areas with healthy tissue in between, while ulcerative colitis involves continuous areas of inflammation. Choices A, B, and D are incorrect because Crohn's disease can affect any part of the digestive tract from mouth to anus, can present with shallow ulcerations or deep fissures, and is transmural, meaning it affects the entire thickness of the bowel wall. On the other hand, ulcerative colitis typically affects the colon and rectum, presents with a continuous pattern of inflammation, and primarily involves the mucosal lining of the colon.

3. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

• A. Proceed with treatment without obtaining written consent
• B. Contact the client's next of kin to obtain consent for treatment
• C. Have the client sign a consent for treatment
• D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

4. The nurse is planning care for a patient with acute hypernatremia. What should the nurse include in this patient's plan of care? (select one that does not apply)

• A. Reduce IV access
• B. Limit length of visits
• C. Restrict fluids to 1500 mL per day
• D. Conduct frequent neurologic checks

Correct answer: D

Rationale: For a patient with acute hypernatremia, the nurse should include interventions like reducing free water losses, correcting sodium levels slowly, monitoring neurologic status, and ensuring adequate fluid intake. Conducting frequent neurologic checks is essential in assessing the patient's neurological status and detecting any changes promptly. Therefore, this action should not be excluded from the plan of care. Choices A, B, and C are not directly related to managing acute hypernatremia and can be safely excluded from the plan of care. Reducing IV access, limiting length of visits, and restricting fluids to 1500 mL per day are not appropriate actions for managing acute hypernatremia.

5. What are the fine, down-like hairs on the newborn's ears, shoulders, lower back, and/or forehead known as?

• A. Vernix.
• B. Lanugo.
• C. Milia.
• D. Vibrissae.

Correct answer: B

Rationale: Lanugo is the term used to describe the fine, down-like hairs found on a newborn's ears, shoulders, lower back, and/or forehead. These hairs are different from vernix, which is a waxy or cheese-like white substance covering the skin of newborns. Milia are small, white, or yellowish cysts that commonly appear on a newborn's face, while vibrissae are the thick, stiff hairs commonly found around the nose and other parts of the face.
