Which diagnostic test will be most useful to the nurse in determining whether a client admitted with acute shortness of breath has heart failure?

The statement "I will call the clinic if my weight goes up 3 pounds in a week" indicates that the teaching about heart failure was effective. Monitoring weight is an essential self-care measure for patients with heart failure to manage fluid retention effectively. A sudden weight gain of 2-3 pounds in a week can indicate fluid retention and worsening heart failure. It is crucial for the patient to report such weight changes promptly to the healthcare provider or clinic to adjust medication doses or treatment plans as needed.

The other statements are incorrect:

A) "I will use the nitroglycerin patch whenever I have chest pain." Nitroglycerin is not typically used to manage heart failure. It is used for angina, which is chest pain caused by reduced blood flow to the heart muscle due to narrowed coronary arteries.

B) "I will take furosemide (Lasix) every day just before bedtime." While furosemide is a diuretic commonly prescribed for heart failure to reduce fluid retention, it is not usually taken just before bedtime. Taking furosemide in the evening may lead to frequent nighttime urination and disrupt sleep.

D) "I will use an additional pillow if I am short of breath at night." Using an extra pillow may provide temporary relief for positional dyspnea (shortness of breath when lying flat) but is not an appropriate long-term strategy for managing heart failure. Elevated pillows may not effectively improve breathing and can lead to neck strain. Instead, patients with heart failure should be encouraged to sleep with their head slightly elevated on a regular basis, using a wedge pillow or adjustable bed if needed. Managing fluid retention and adhering to prescribed medications are essential for improving heart failure symptoms and preventing complications.

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.
