Physiological response to fear and anxiety includes which of the following?

Choice A reason: Environmental stress is not the correct answer. Environmental stress is caused by external factors that are beyond the person's control, such as noise, pollution, weather, or natural disasters. These factors can affect the person's physical and mental health, but they are not related to the person's specific situation or event.

Choice B reason: Situational stress is the correct answer. Situational stress is caused by a particular situation or event that the person faces, such as a test, a job interview, a conflict, or a loss. These situations or events can create pressure, uncertainty, or anxiety for the person, and they may require the person to adapt or cope with the change or challenge.

Choice C reason: Daily Hassle stress is not the correct answer. Daily Hassle stress is caused by the minor annoyances or frustrations that the person encounters in their everyday life, such as traffic, deadlines, bills, or household chores. These hassles can accumulate and affect the person's mood, health, or well-being, but they are not related to the person's specific situation or event.

Choice D reason: Episodic stress is not the correct answer. Episodic stress is caused by frequent or chronic exposure to stressful situations or events, such as work overload, financial problems, or family issues. These situations or events can create a constant state of worry, agitation, or distress for the person, and they may affect the person's physical and mental health. Episodic stress is not a type of stress, but rather a result of experiencing too much stress over a long period of time.

Choice A reason: This is the correct answer because stopping the KCl infusion is the first and most urgent action that the nurse should take. A high level of potassium in the blood, or hyperkalemia, can cause life-threatening cardiac arrhythmias and muscle weakness. The nurse should stop the source of excess potassium, which is the KCl infusion, and monitor the client's vital signs, electrocardiogram, and symptoms.

Choice B reason: This is not the correct answer because administering oral KCl is not the first or appropriate action that the nurse should take. Oral KCl would increase the potassium level in the blood, which is already too high. The nurse should avoid giving any potassium supplements or foods that are high in potassium, such as bananas, oranges, and potatoes.

Choice C reason: This is not the correct answer because encouraging fluids for dilution is not the first or effective action that the nurse should take. Fluids alone would not lower the potassium level in the blood, but rather dilute the concentration of other electrolytes, such as sodium and calcium. The nurse should administer fluids only as prescribed by the physician, and in conjunction with other treatments, such as diuretics, insulin, or sodium bicarbonate.

Choice D reason: This is not the correct answer because calling the pharmacy is not the first or priority action that the nurse should take. Calling the pharmacy may be necessary to obtain the medications that can lower the potassium level in the blood, such as diuretics, insulin, or sodium bicarbonate. However, the nurse should first stop the KCl infusion and notify the physician, who will order the appropriate medications and dosages.
