Correct Answer: D

Rationale: The correct first action for a client who has just vomited 300 cc of bright red blood is to check the blood pressure. This assessment is crucial to evaluate for hypotension, which could indicate significant blood loss and the need for immediate intervention. Documenting the vomiting is important for the client's medical record but not the initial priority. Increasing IV fluids and getting a complete blood count are necessary steps but should follow the assessment of the client's hemodynamic status.

Correct Answer: B

Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.

Correct Answer: A

Rationale: Coma is a sign that a nurse might observe in a client with a high ammonia level. Elevated ammonia levels can lead to hepatic encephalopathy, a condition characterized by impaired brain function, which can progress to coma. Edema (choice B) is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia (choice C) is a condition of inadequate oxygen supply to tissues and is not directly related to high ammonia levels. Polyuria (choice D) refers to excessive urination and is not a typical sign of high ammonia levels.

Correct Answer: B

Rationale: A sprain is the correct term for the excessive stretching of a ligament, which is what happens when a ligament is pulled. A strain involves muscle tissue. Subluxation refers to a partial dislocation, and dislocation is a complete displacement of bones in a joint. In this case, since it's a pulled ligament, the most appropriate term is a sprain.

Correct Answer: B

Rationale: The correct answer is 'To provide data for analysis by a risk manager to determine how future problems can be avoided.' Incident reports are a crucial tool for collecting information about incidents to analyze them and prevent similar issues in the future. They are not primarily used for liability protection or disciplining staff. Therefore, choices A and C are incorrect. Selecting 'All of the above' (choice D) is not accurate as incident reports serve a specific purpose related to data analysis and risk prevention, excluding liability protection and staff discipline.
