A nurse is teaching a client about foods and beverages that can cause diarrhea. Which of the following should the nurse include in the teaching?

Choice A reason: Tachycardia is a physiological response to fear and anxiety. Tachycardia is a condition where the heart rate is faster than normal, usually above 100 beats per minute. Fear and anxiety can trigger the release of stress hormones, such as adrenaline and cortisol, that stimulate the sympathetic nervous system. This causes the heart to beat faster and stronger, increasing the blood flow and oxygen delivery to the muscles and organs. This prepares the body for the fight-or-flight response, which is a survival mechanism that helps the person to cope with a perceived threat or danger.

Choice B reason: Bronchial constriction is not a physiological response to fear and anxiety. Bronchial constriction is a condition where the airways in the lungs become narrow and inflamed, reducing the airflow and causing difficulty breathing. Bronchial constriction can be caused by various factors, such as asthma, allergies, infections, or irritants. Fear and anxiety can worsen the symptoms of bronchial constriction, but they are not the primary cause of it.

Choice C reason: Bradypnea is not a physiological response to fear and anxiety. Bradypnea is a condition where the breathing rate is slower than normal, usually below 12 breaths per minute. Bradypnea can be caused by various factors, such as brain injury, drug overdose, sleep apnea, or metabolic disorders. Fear and anxiety can increase the breathing rate, not decrease it, as the body needs more oxygen to cope with the stress.

Choice D reason: Pupillary constriction is not a physiological response to fear and anxiety. Pupillary constriction is a condition where the pupils in the eyes become smaller and less responsive to light. Pupillary constriction can be caused by various factors, such as eye injury, medication, aging, or neurological disorders. Fear and anxiety can cause pupillary dilation, not constriction, as the pupils widen to allow more light and improve the vision. This helps the person to see better and react faster to the situation.

Choice A reason: This is the correct answer because the RN as a teacher aims to promote health literacy, self-management, and shared decision-making among patients and their families. By helping people to become empowered to take care of their health, the RN can facilitate positive health outcomes and prevent complications.

Choice B reason: This is not the correct answer because the RN as a teacher does not focus on explaining what nurses do, but rather on educating patients about their health conditions, treatments, and self-care. While it is important for the patient to understand the role of the nurse, this is not the main goal of teaching.

Choice C reason: This is not the correct answer because the RN as a teacher does not limit teaching to discharge instructions. Teaching is an ongoing process that starts from admission and continues throughout the continuum of care. Discharge instructions are only one component of teaching that summarizes the key information and actions that the patient needs to follow after leaving the hospital.

Choice D reason: This is not the correct answer because the RN as a teacher does not aim to teach patients how to give themselves treatments to get them out of the hospital quicker, but rather to help them achieve optimal health and wellness. Teaching patients how to give themselves treatments is part of the skill development aspect of teaching, but it is not the main goal. The main goal is to help patients understand the rationale, benefits, and risks of their treatments, and to support them in adhering to their treatment plans.
