When caring for Mr. Reyes, the nurse should assess for

Correct Answer: B

Rationale: The correct answer is B, Altered level of consciousness, because it is a critical assessment in determining Mr. Reyes's neurological status and overall well-being. Assessing for altered level of consciousness helps identify potential neurological issues, such as brain injury or stroke, which require immediate intervention. A: Decreased carotid pulses - This is related to cardiovascular assessment, not specific to Mr. Reyes's neurological status. C: Bleeding from oral cavity - While important to assess for, it is not directly related to Mr. Reyes's neurological status. D: Absence of deep tendon-reflexes - This is a specific neurological assessment, but altered level of consciousness takes priority in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Positioning the patient on his or her side. This is essential for a lumbar puncture as it helps to open up the spinal spaces, making it easier and safer for the procedure. Positioning the patient on their side also helps prevent complications such as nerve damage or spinal fluid leakage. A: Administering enemas until clear is unnecessary and not directly related to preparing a patient for a lumbar puncture. C: Removing all metal jewelry is important to prevent interference with imaging studies, but it is not directly related to preparing for a lumbar puncture. D: Removing the patient’s dentures is not specifically required for a lumbar puncture procedure.

Correct Answer: C

Rationale: The correct answer is C: Eating. Chewing food can trigger trigeminal nerve pain due to the movement and pressure applied on the nerve. The other choices (A: Sleeping, B: Reading, D: Cooking) do not involve the same level of jaw movement and pressure on the trigeminal nerve, thus are less likely to aggravate the pain. Therefore, eating is the most likely action to worsen trigeminal neuralgia symptoms in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Maintenance of a clear airway. In cases of coma or unconsciousness, ensuring a clear airway is crucial to prevent respiratory complications and maintain oxygenation. This involves positioning the patient correctly, suctioning if necessary, and monitoring breathing. Choice B, good nursing care, is too broad and does not address the immediate priority of airway management. Choice C, retention of a catheter, is irrelevant to managing a coma or unconsciousness. Therefore, the correct therapeutic measure in this scenario is to focus on maintaining a clear airway to support respiratory function.

Correct Answer: B

Rationale: The correct answer is B because a Snellen chart reading of 20/80 means the patient can see at 20 feet what a normal eye can see at 80 feet. This indicates that the patient's vision is below average. Choice A is incorrect because it reverses the numerator and denominator. Choice C is incorrect because it does not accurately represent the Snellen chart findings. Choice D is incorrect because 20/80 is not considered normal vision.
