A client diagnosed with emphysema has severe shortness of breath and needs portable oxygen when leaving home.

Recently the client has reduced activity because of fear that breathing difficulty will occur.

A nurse suggests using guided imagery.

Which image should the client be encouraged to visualize?

Choice A rationale

A decrease in heart rate (P) and respiratory rate (R) would indicate a state of relaxation or a calming of the nervous system. The client has just been informed of a necessary surgery, a significant stressor that would activate the sympathetic nervous system, leading to an increase in vital signs, not a decrease. This choice is inconsistent with the expected physiological response.

Choice B rationale

The initial vital signs (P 72, R 16) represent the client's baseline state upon arrival. The new stressor of impending surgery would trigger a physiological response that elevates these values. Therefore, vital signs remaining unchanged after receiving this information is highly unlikely. The sympathetic nervous system would initiate a fight-or-flight response.

Choice C rationale

The news of impending surgery acts as a significant stressor, activating the sympathetic nervous system. This "fight-or-flight" response releases catecholamines like epinephrine and norepinephrine. These hormones cause an increase in heart rate (tachycardia) and respiratory rate (tachypnea) to enhance oxygen delivery to muscles, preparing the body for a perceived threat.

Choice D rationale

A decrease in pulse and respiration would indicate a parasympathetic nervous system response, which is associated with "rest and digest" functions. This is the opposite of the expected physiological reaction to the stress of a required surgery. The body's natural response to such a stressor is to increase, not decrease, these vital parameters.

Choice A rationale

This choice may induce anxiety and frustration by highlighting the client's current limitations in contrast to a former, healthier state. Focusing on an unattainable image can trigger a stress response, increasing sympathetic nervous system activity. This can lead to bronchoconstriction and a higher respiratory rate, exacerbating their shortness of breath, which is counterproductive to the goal of guided imagery. The aim is to calm and relax the client.

Choice B rationale

This choice is inappropriate for a client with emphysema because surfing is a strenuous activity. Suggesting this image could create a mental conflict for the client, as their physical limitations prevent them from performing such an action. The incongruity between the imagined activity and their physical reality can cause stress, leading to an increase in oxygen consumption and a higher respiratory rate, which would worsen their dyspnea.

Choice C rationale

This choice is unsuitable because it denies the client's need for oxygen, which is a critical part of their treatment plan. Visualizing an activity without supplemental oxygen may lead to anxiety and a sense of vulnerability when they must use it. Guided imagery should reinforce positive coping mechanisms, not dismiss necessary medical interventions. This can trigger a fear of suffocation, increasing their respiratory effort and anxiety.

Choice D rationale

This choice is the most effective because it focuses on a positive, attainable state of being. The image of feeling relaxed and taking deep breaths directly addresses the client's fear and physiological symptoms. It promotes a parasympathetic response, which can lead to bronchodilation and a reduced respiratory rate, thereby easing their shortness of breath and lowering their anxiety. This image provides a concrete and therapeutic focus. *.
