The nurse is caring for a patient who is having a heart attack. The patient tells the nurse that the pain is down his left arm rather than in his chest. What type of pain is the patient experiencing?

Choice A reason: This is an incorrect choice because the axillary method is not the most accurate measurement of the core temperature. The axillary method involves placing a thermometer under the patient's armpit and measuring the temperature of the skin surface. This method can be affected by factors such as sweating, clothing, and ambient temperature. The axillary method can underestimate the core temperature by 0.5°C to 1.5°C¹.

Choice B reason: This is an incorrect choice because the oral method is not the most accurate measurement of the core temperature. The oral method involves placing a thermometer in the patient's mouth and measuring the temperature of the sublingual pocket. This method can be affected by factors such as eating, drinking, smoking, and mouth breathing. The oral method can underestimate the core temperature by 0.3°C to 0.8°C¹.

Choice C reason: This is the correct choice because the rectal method is the most accurate measurement of the core temperature. The rectal method involves inserting a thermometer into the patient's rectum and measuring the temperature of the rectal mucosa. This method reflects the temperature of the blood flowing through the core of the body. The rectal method is considered the gold standard for measuring the core temperature¹.

Choice D reason: This is an incorrect choice because the forehead method is not the most accurate measurement of the core temperature. The forehead method involves placing a thermometer on the patient's forehead and measuring the temperature of the temporal artery. This method can be affected by factors such as sweating, hair, and ambient temperature. The forehead method can overestimate or underestimate the core temperature by 0.5°C to 1°C¹.

Choice A reason: This is correct. Teaching the patient to wear low-heeled, comfortable, supportive footwear at all times is the highest priority intervention for a patient with diabetic neuropathy who has lost sensation in both feet. This can prevent foot injuries, ulcers, and infections that can lead to amputation.

Choice B reason: This is incorrect. Encouraging the patient to participate in tai chi exercises to promote balance is a beneficial intervention for a patient with diabetic neuropathy who has lost sensation in both feet, but not the highest priority. Tai chi can improve muscle strength, coordination, and flexibility, but it does not protect the feet from injury.

Choice C reason: This is incorrect. Evaluating the patient's blood pressure for orthostatic hypotension is an important intervention for a patient with diabetic neuropathy who has lost sensation in both feet, but not the highest priority. Orthostatic hypotension is a condition where the blood pressure drops when the patient changes position, causing dizziness and fainting. It can be caused by autonomic neuropathy, which affects the nerves that control blood pressure and heart rate.

Choice D reason: This is incorrect. Instructing the patient to wear a medical alert bracelet that identifies risk for falls is a helpful intervention for a patient with diabetic neuropathy who has lost sensation in both feet, but not the highest priority. A medical alert bracelet can alert emergency personnel of the patient's condition and medications, but it does not prevent falls or foot injuries.
