A woman, abducted and raped at gunpoint by an unknown assailant, was found confused and disoriented. The nurse makes these observations about the patient: talking rapidly in disjointed phrases, unable to concentrate, indecisive when asked to make simple decisions. What is the patient's level of anxiety?
- A. Weak
- B. Mild
- C. Moderate
- D. Severe
Correct Answer: D
Rationale: The correct answer is D: Severe. The patient's symptoms of talking rapidly, inability to concentrate, and indecisiveness are indicative of severe anxiety. Rapid speech and disjointed phrases suggest heightened arousal, while the inability to concentrate and make decisions point to severe impairment in cognitive functioning. These symptoms align with the DSM-5 criteria for severe anxiety, which includes extreme levels of distress and impairment in daily functioning. Weak (A), mild (B), and moderate (C) levels of anxiety would not typically manifest in such severe cognitive and behavioral symptoms.
The family of a client mentions to the nurse, 'The family therapist talked to us about enmeshment. We're not sure we understood what it meant.' The nurse should base a response on knowledge that an enmeshed family is a unit in which:
- A. individuality is encouraged.
- B. boundaries are poorly defined.
- C. conflict is effectively resolved.
- D. social acceptance is deemed unimportant.
Correct Answer: B
Rationale: The correct answer is B: boundaries are poorly defined. In an enmeshed family, boundaries between family members are blurred, leading to a lack of individual autonomy and independence. Enmeshment can result in difficulties in establishing personal identities and healthy relationships. Choices A, C, and D are incorrect because individuality is not encouraged, conflict is not effectively resolved, and social acceptance is not necessarily deemed unimportant in an enmeshed family dynamic.
What is a key consideration when treating a patient with anorexia nervosa?
- A. Addressing the patient's weight first and foremost.
- B. Focusing on nutrition and caloric intake without addressing underlying issues.
- C. Addressing the psychological and emotional factors that contribute to the disorder.
- D. Providing strict dietary restrictions to help the patient regain control over food.
Correct Answer: C
Rationale: The correct answer is C because addressing the psychological and emotional factors is crucial in treating anorexia nervosa. This disorder is not solely about weight or food intake; it often involves deeper psychological issues such as body image distortion, low self-esteem, and control issues. By focusing on the underlying psychological and emotional factors, therapists can help patients understand and cope with these issues, leading to more effective and sustainable recovery. Choices A, B, and D are incorrect because they overlook the complexity of anorexia nervosa and may even exacerbate the patient's condition by neglecting the root causes of the disorder.
Which therapy is shown through evidence to be the most effective for a patient with an eating disorder?
- A. Supportive therapy.
- B. Behavioral therapy.
- C. Cognitive behavioral therapy.
- D. Psychoanalytical group therapy.
Correct Answer: C
Rationale: The correct answer is C: Cognitive behavioral therapy (CBT). CBT is the most effective therapy for eating disorders based on research evidence. It helps patients identify and change negative thoughts and behaviors related to food and body image. CBT also teaches coping skills and strategies to manage triggers. Supportive therapy (choice A) offers emotional support but may not target the underlying issues. Behavioral therapy (choice B) focuses on changing specific behaviors but may not address cognitive patterns. Psychoanalytical group therapy (choice D) delves into past experiences but is not as effective as CBT in treating eating disorders.
The client tells the nurse, 'I thought my psychiatrist was the best doctor in the world. I thought he understood me completely. Now, I hate him! He doesn't understand me at all. He's just dumping me to go on a 2-week vacation.' The nurse assesses the client's description of feelings about the physician as evidence of the use of:
- A. Splitting
- B. Projective identification
- C. Isolation of affect
- D. Dissociation
Correct Answer: A
Rationale: The correct answer is A: Splitting. Splitting is a defense mechanism where a person sees things as all good or all bad, leading to extreme shifts in perception. In this case, the client initially viewed the psychiatrist as the best doctor but now hates him completely due to feeling abandoned. This sudden shift from idealization to devaluation is characteristic of splitting.
Choice B: Projective identification involves attributing one's own unacceptable feelings or traits onto another. This is not evident in the client's description.
Choice C: Isolation of affect refers to separating emotions from their source. The client is expressing strong emotions towards the psychiatrist, not isolating them.
Choice D: Dissociation involves a disruption in consciousness, memory, identity, or perception. The client is not displaying symptoms of dissociation in this scenario.
