A brain disorder

Answer and Explanation

The Correct Answer is D

Choice A reason: The theory that schizophrenia is primarily related to a disturbed mother-child relationship is outdated and not supported by current research.

Correct Answer is C

Explanation

Choice A reason: Hypertension is not typically a direct complication of inhaled anesthetics.

Choice B reason: Urinary retention can occur postoperatively but is not specifically associated with inhaled anesthetics.

Choice C reason: Laryngospasm is a potential complication of inhaled anesthetics, which can occur due to irritation of the airway during anesthesia.

Choice D reason: Anxiety is not a complication of inhaled anesthetics; it is more likely to be associated with preoperative stress.

A. "Relax. Take a few deep breaths. I'll stay with you." B. "I'll take your vital signs and call my supervisor." C. "Don't worry. She's done this many times before." D. "Why do you think you're having a heart attack, Mr. L?"

Correct Answer is A

Explanation

Choice A reason: This response is calming and supportive. It addresses Mr. L's immediate distress by providing reassurance and a directive that can help him manage his panic, which is essential in a situation where a patient is experiencing extreme anxiety.

Choice B reason: While taking vital signs is an important step, it should not be the first response. The priority is to address the patient's acute distress and provide reassurance.

Choice C reason: This response minimizes the patient's feelings and does not address his immediate fear or offer any comfort or support.

Choice D reason: Asking why he thinks he's having a heart attack could increase his anxiety. It's important to first calm the patient before attempting to rationalize the situation.
