Correct Answer: B

Rationale: The correct statement regarding preparation for a lipoprotein fractionation test is that the client cannot eat for 12 hours before the test. It is important to note that the client can drink an unrestricted amount of water. Limiting fluid intake is not necessary for this test. There is no need for the client to ingest a lipid solution as part of the preparation. Therefore, the other choices are incorrect.

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: 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: A

Rationale: When assessing a client's mobility status, it is crucial to start by examining their gait. Gait assessment is usually conducted as the client walks into the room. Normal gait is described as smooth, flowing, and rhythmic without the need for assistive devices. Choices B, C, and D are incorrect as they do not represent the standard practice of beginning the assessment of mobility status with gait examination.

Correct Answer: C

Rationale: The correct answer is '"I should lay him on his back during a seizure."?' When a client is having a seizure, it is crucial to turn them onto their side to prevent aspiration of secretions. Placing them on their back can lead to potential airway compromise. Choices A, B, and D are correct statements that indicate a good understanding of caring for a child with a seizure disorder: ensuring rest, getting a medical alert bracelet for identification, and loosening clothing to facilitate breathing during a seizure.
