Adaptation Theories and Models

Every question here, with the answer

1. A patient becomes tachycardic and tachypneic with elevated blood pressure after a sudden stressful event. Which interpretation best fits the nurse’s assessment using general adaptation syndrome?

   1. The patient is in exhaustion because the body has no remaining resources to resist the stressor.
   2. The patient is in the alarm stage, with SNS activation preparing the body to face the stressor.
   3. The patient is in the resistance stage, with PSNS activity restoring homeostasis.
   4. The patient is showing allostasis because vital signs have already returned to baseline.

   Answer: The patient is in the alarm stage, with SNS activation preparing the body to face the stressor.

   The alarm stage of GAS is associated with SNS activation and signs such as tachycardia, tachypnea, and elevated blood pressure. Resistance would involve effective adaptation and PSNS opposition to SNS effects, while exhaustion occurs when resources to resist the stressor are depleted.

2. A nurse is evaluating whether a patient has effectively adapted during the resistance stage of GAS after a stressor. Which findings would support effective adaptation? Select all that apply.

   1. PSNS activation is opposing the stimulating effects of the SNS.
   2. The threat from the stressor has dissipated.
   3. Homeostasis is restored.
   4. The patient’s SNS effects continue to intensify without relief.
   5. The patient progresses to exhaustion because coping is ineffective.

   Answer: PSNS activation is opposing the stimulating effects of the SNS., The threat from the stressor has dissipated., Homeostasis is restored.

   In the resistance stage, effective adaptation allows the stressor’s threat to dissipate, PSNS activity opposes SNS stimulation, and homeostasis returns. Ongoing intensified SNS effects or progression to exhaustion suggests ineffective coping rather than effective adaptation.

3. A patient reports long-term stress that feels greater than their ability to cope. The nurse is concerned this pattern may contribute to chronic stress-related health problems. Which concept best describes this situation?

   1. Allostatic overload
   2. Homeostasis
   3. Eustress
   4. Regulator response

   Answer: Allostatic overload

   Allostatic overload occurs when the stress or threat exceeds the person’s coping ability. Homeostasis refers to balance, and a regulator response is an automatic coping reaction in Roy’s model, not the overall state of stress exceeding coping capacity.

4. A nurse is planning care using Roy’s adaptation model for a patient with ineffective coping related to health stressors. Which nursing actions are consistent with this model? Select all that apply.

   1. Assume adaptation is unlimited if the patient is motivated.
   2. Focus only on the diagnosis and avoid addressing the patient’s environment.
   3. Include the patient’s role in managing stress when possible.
   4. Help alter ineffective behaviors into more adaptive behaviors.
   5. Support behaviors that help the patient adapt effectively.

   Answer: Include the patient’s role in managing stress when possible., Help alter ineffective behaviors into more adaptive behaviors., Support behaviors that help the patient adapt effectively.

   Roy’s adaptation model emphasizes fostering adaptive behavior, changing ineffective behavior, and recognizing the patient as more than a reflexive participant in stress. The model includes environment, and the section states adaptation is limited by body resources and coping ability.

5. During assessment, a nurse is identifying predisposing risk factors that may affect a patient’s stress response. Which findings should the nurse consider risk-related cues? Select all that apply.

   1. Coping mechanisms that have been ineffective in the past
   2. A tendency to reach high anxiety or crisis point easily
   3. A history of adverse childhood experiences
   4. The absence of current stressors means risk factors do not need assessment
   5. A health and surgical history that may contribute to stress

   Answer: Coping mechanisms that have been ineffective in the past, A tendency to reach high anxiety or crisis point easily, A history of adverse childhood experiences, A health and surgical history that may contribute to stress

   The section identifies ACEs, high anxiety or crisis points, prior ineffective coping mechanisms, and health or surgical history as possible risk factors affecting stress and homeostasis. Risk-factor assessment is part of recognizing cues, even before narrowing the current stressor.

6. An older adult patient has fluid volume deficit related to forgetfulness, diminished thirst, and difficulty ambulating to get water. Which actions are constructive ways to support adaptation and homeostasis? Select all that apply.

   1. Use a loud alarm even if it startles the patient and causes agitation.
   2. Keep an assistive device nearby so the patient can ambulate to get water more easily.
   3. Wait for the patient to feel thirsty before offering strategies to improve fluid access.
   4. Keep water available in a cooler or insulated beverage container near the bed or chair.
   5. Place a bedside commode near the bed or chair to reduce anxiety about walking to the toilet.

   Answer: Keep an assistive device nearby so the patient can ambulate to get water more easily., Keep water available in a cooler or insulated beverage container near the bed or chair., Place a bedside commode near the bed or chair to reduce anxiety about walking to the toilet.

   Constructive actions improve access to fluids and reduce barriers such as ambulation difficulty or anxiety about toileting. The section notes that alarms or phone reminders may be startling and cause fear or agitation, which can create negative stress.
