A nurse is developing home care instructions for a client with peripheral artery disease (PAD). Which intervention should the nurse include?

Choice A reason: Polyuria and excessive thirst are classic symptoms of diabetes insipidus and indicate the body's inability to retain water due to a lack of antidiuretic hormone (ADH). While these symptoms need to be managed, they are not immediately life-threatening compared to severe hypernatremia.

Choice B reason: A serum sodium level of 185 mEq/L (185 mmol/L) indicates severe hypernatremia, which is an immediate medical emergency. Severe hypernatremia can lead to neurological symptoms such as confusion, seizures, and even coma due to the osmotic shift of water out of brain cells. Immediate intervention is required to correct the sodium imbalance and prevent serious complications.

Choice C reason: An apical heart rate of 110 beats per minute is indicative of tachycardia, which can be associated with dehydration and the body's response to maintain cardiac output. While it is a concern, it does not take precedence over the need to address severe hypernatremia.

Choice D reason: Dry skin with inelastic turgor is a sign of dehydration, which is a common issue in diabetes insipidus due to excessive fluid loss. While this requires attention, it is not as immediately critical as addressing severe hypernatremia, which poses a direct and urgent threat to the client's neurological and overall health.

Choice A reason: Checking the blood pressure every five minutes for one hour is important, especially if the blood pressure is unstable. However, this action does not address the immediate issue of the client’s low temperature, which needs to be verified and addressed promptly to prevent complications such as hypothermia.

Choice B reason: Taking the client's temperature using another method is crucial. The extremely low tympanic temperature reading may not be accurate, and confirming the client's core body temperature is essential. Hypothermia can lead to serious complications, including altered cardiovascular and respiratory function, and needs to be managed promptly.

Choice C reason: Raising the head of the bed to 60 to 90 degrees is not appropriate in this situation. Elevating the head of the bed is typically done to improve respiratory function or decrease intracranial pressure, but it does not address the potential issue of hypothermia indicated by the low temperature reading.

Choice D reason: Asking the client to cough and deep breathe is a good practice to prevent postoperative complications such as atelectasis, but it is not the priority intervention in this scenario. The immediate concern is verifying the client's temperature to rule out or address hypothermia.
