A patient is apneic and has no palpable pulses. The heart monitor shows sinus tachycardia, rate 132. What action should the nurse take next?

Among the four patients with hypertension, the nurse should assess the patient in option B first, the 48-year-old with a blood pressure of 160/92 mm Hg who reports chest pain.

Chest pain is a potentially serious symptom that could indicate an acute cardiac event, such as angina or a heart attack. Given that the patient has hypertension and is experiencing chest pain, the nurse must prioritize this assessment to rule out any cardiac-related complications or other urgent issues.

While all the other patients have elevated blood pressure readings, they have additional symptoms or conditions that indicate potential complications related to their hypertension. However, chest pain is a red flag that requires immediate attention and further assessment to determine its cause and provide appropriate interventions promptly.

Option A, the 52-year-old with a blood pressure of 198/90 mm Hg who has intermittent claudication, may have peripheral vascular disease or other vascular issues related to hypertension, but it is not as acutely concerning as chest pain.

Option C, the 43-year-old with a blood pressure of 172/98 mm Hg whose urine shows microalbuminuria, may have early signs of kidney involvement due to hypertension, which is significant and requires attention but may not be as immediately urgent as chest pain.

Option D, the 50-year-old with a blood pressure of 190/104 mm Hg who has a creatinine of 1.7 mg/dL, may have signs of kidney impairment related to hypertension, which is also significant but may not be as acutely urgent as chest pain.

In summary, the nurse should prioritize the assessment of the patient experiencing chest pain (option B) to address any potential cardiac-related issues promptly and ensure appropriate management and intervention.

Hemodialysis is a treatment used to remove waste products and excess fluids from the blood in individuals with kidney failure or chronic kidney disease. The primary purpose of hemodialysis is to filter and clear the blood of waste products that the kidneys can no longer remove adequately. As a result, one of the key indicators that hemodialysis is having the desired effect is a decrease in serum creatinine levels. Creatinine is a waste product that builds up in the blood when the kidneys are not functioning properly. A decrease in serum creatinine indicates that the dialysis treatment is effectively removing waste products from the blood.

Weight loss is also a positive sign after hemodialysis since it indicates that excess fluid is being removed from the body. In individuals with kidney failure, the kidneys cannot adequately remove extra fluid, leading to fluid retention and weight gain. Hemodialysis helps to eliminate this excess fluid, leading to weight loss and reducing the risk of fluid overload-related complications.

The other options listed (decreased hematocrit and diuresis, increased potassium level and improved appetite, and decreased white blood cell count and diaphoresis) are not direct indicators of the effectiveness of hemodialysis in removing waste products and excess fluid from the blood.
