Mr. Reyes has a possible skull fracture. The nurse should:

Correct Answer: A

Rationale: The correct answer is A because signs of brain injury, such as altered level of consciousness, unequal pupil size, and clear fluid draining from the nose or ears, indicate a need for urgent medical attention. Choice B is incorrect because hemorrhaging from the oral cavity is not a common sign of a skull fracture. Choice C is incorrect as elevating the foot of the bed is not appropriate for a skull fracture but may be done for shock. Choice D is incorrect because decreased intracranial pressure and temperature are not typical symptoms of a skull fracture.

Correct Answer: A

Rationale: The correct answer is A: Position the client flat for at least 3 hrs or as directed by the physician. Rationale: 1. Positioning the client flat helps prevent post-lumbar puncture headache by allowing the CSF to replenish and stabilize the pressure in the spinal canal. 2. The recommended time frame of 3 hours allows for adequate CSF reabsorption and reduces the likelihood of headache. 3. Following physician's direction is crucial to individualize care based on the specific situation. Summary of other choices: B: Encouraging fluid intake is generally good practice but may not directly alleviate post-lumbar puncture headache. C: Keeping the room well lit and playing soothing music may not address the physiological cause of the client's symptoms. D: Ambulation and leg exercises are not recommended immediately post-lumbar puncture as they may exacerbate dizziness and headache.

Correct Answer: B

Rationale: Correct Answer: B (High fat diet) Rationale: 1. Ketogenic diet for seizures aims to produce ketones for brain energy, achieved through high fat intake. 2. High fat intake helps induce ketosis, which may help reduce seizures in some children. Incorrect Choices: A: High carbohydrate diet - Contradicts the purpose of a ketogenic diet. C: High protein diet - Excessive protein can hinder ketosis and is not the primary focus of a ketogenic diet. D: Low fat diet - Opposite of the high fat requirement for a ketogenic diet to induce ketosis.

Correct Answer: C

Rationale: The correct answer is C because it addresses the specific nursing intervention needed to prepare Mr. RR for the brain scanning test. By explaining to Mr. RR that the test will not be painful and that his head will be supported in place, the nurse helps alleviate any potential anxiety or fear he may have. This information reassures the patient and ensures his cooperation during the procedure. Choice A is incorrect because discontinuing anticonvulsant therapy without medical approval could have serious consequences for Mr. RR's health. Choice B is also incorrect as obtaining consent is important, but it is not directly related to preparing Mr. RR for the test. Choice D is incorrect as it introduces potential negative outcomes without providing necessary information to prepare the patient for the test.

Correct Answer: A

Rationale: The correct answer is A: Peripheral vision. When testing visual fields, the nurse evaluates the ability to see objects outside the direct line of sight, which is indicative of peripheral vision. Peripheral vision helps detect objects and movement in the side vision. Distance vision (B) refers to the ability to see clearly at a distance, while near vision (C) pertains to close-up vision. Central vision (D) is essential for focusing on details and seeing straight ahead. Therefore, A is the correct choice as it specifically pertains to the assessment of visual fields.
