During her shift at the hospital, a nurse receives a stern reprimand from a physician over something over which she had no control. The nurse does not respond. When she returns home that evening, she sees her children's toys all over the floor, gets mad, and begins to yell at them. Which form of defense mechanism is this nurse using?

Correct Answer: C

Rationale: Displacement is the process of redirecting feelings or impulses from one person to another. In this scenario, the nurse chose not to respond to the physician, but instead displaced her negative emotions onto her children, who are less threatening and more vulnerable. This defense mechanism allowed her to express her anger in a safer outlet. Symbolization involves representing unconscious feelings or impulses through symbols, not redirecting them. Suppression is the conscious effort to push unwanted thoughts or feelings out of awareness, not displacing them onto others. Projection involves attributing one's thoughts or emotions to someone else, which is not evident in this case.

Correct Answer: A

Rationale: The correct answer is an 80-year-old man who lost his wife last year. Certain factors increase the risk of suicide, such as recent loss of a loved one, in this case, the man's wife. The elderly are a high-risk group due to factors like social isolation, physical health issues, and bereavement. While experiencing a loss can affect anyone, the combination of age, loss of a spouse, and the associated emotional impact elevates the risk significantly. The other choices are not at the highest risk of suicide. A former alcoholic who has been sober for 12 years has taken steps towards recovery, reducing the immediate risk. A 40-year-old married businessman and a 36-year-old woman whose former neighbor committed suicide do not have the same level of immediate risk as the elderly man who recently lost his wife.

Correct Answer: D

Rationale: The correct answer is D: Lack of menstruation. Amenorrhea, or lack of menstruation, is a common occurrence in individuals with anorexia nervosa. The induced starvation from anorexia can disrupt hormone levels, leading to menstrual irregularities. This hormonal imbalance can result in amenorrhea, which can have long-term consequences such as osteoporosis and infertility. Choices A, B, and C are incorrect. Weight loss of more than 2% body fat may be a consequence of anorexia but is not a specific assessment finding. Frequent binge-eating episodes followed by induced vomiting are more characteristic of bulimia nervosa, not anorexia nervosa. A history of poor academic performance and mediocre achievements is not a typical assessment finding related to anorexia nervosa symptoms.

Correct Answer: C

Rationale: In alcohol withdrawal, stage 3 typically begins about 12-48 hours after the last drink. It includes symptoms from stages 1 and 2 like tremors, tachycardia, mild hallucinations, hyperactivity, and confusion. By stage 3, severe hallucinations and seizures can occur. Choice A, stage 1, is too early for the described symptoms. Stage 2, as described, is also too early as it typically occurs within 6-12 hours. Stage 4 is not a recognized stage in alcohol withdrawal protocols.
