Which of the following therapies is based on 'learning theory'?

Correct Answer: A

Rationale: Learning theory underpins therapies that modify behavior through principles like conditioning. Behaviour therapy (choice A) directly applies learning theory, using techniques such as operant conditioning (rewards/punishments) and classical conditioning (stimulus-response pairing) to address maladaptive behaviors, like phobias or addiction. Psychoanalytic therapy (choice B) focuses on unconscious conflicts and past experiences, rooted in Freudian theory, not learning principles. Milieu therapy (choice C) emphasizes a therapeutic environment to foster social learning, but it's not strictly based on learning theory's conditioning mechanisms. Cognitive therapy (choice D) targets thought patterns to change behavior, incorporating some learning elements but primarily stemming from cognitive psychology. Choice A is correct because behaviour therapy explicitly relies on learning theory's framework, systematically altering behaviors through reinforcement or desensitization. Nurses use this in practice, such as in managing anxiety disorders with exposure techniques, highlighting its relevance in clinical settings where observable behavior change is the goal.

Correct Answer: A

Rationale: Nelson syndrome follows bilateral adrenalectomy (choice A), often for Cushing's, causing ACTH oversecretion from pituitary hyperplasia, darkening skin, and tumor risk. Hypopituitarism (choice B) reduces hormones, opposite effect. Hyperpituitarism (choice C) is unrelated. Growth hormone deficiency (choice D) doesn't cause this. A is correct, per endocrinology. Nurses monitor ACTH, skin changes, and support imaging, managing this rare sequel.

Correct Answer: B

Rationale: During recovery from massive tissue loss, Imelda needs a high protein, high calorie diet with vitamins A and C (B). Protein supports tissue repair and collagen synthesis, vital for wound healing. High calories provide energy for metabolic demands of recovery. Vitamins A and C enhance epithelialization and collagen formation. Low calorie options (A, D) lack energy for healing, while low protein (C, D) hinders tissue regeneration. This nutrient-rich diet matches the needs of second intention healing, where extensive repair occurs, making B the correct choice.

Correct Answer: A

Rationale: Biofeedback (A) uses machines to display pulse, temperature, and muscle tension, allowing Lyza to visualize and control them. Massage (B) is physical, not machine-based. Autogenic training (C) involves self-suggestion, not devices. Visualization (D) is mental imagery, not monitored. Biofeedback trains self-regulation via real-time data, per psychology, matching the description and making A correct.
