The nurse is caring for a patient newly diagnosed with chronic obstructive pulmonary disease (COPD), who has an order for prednisone orally. When planning medication teaching, the nurse will plan to include which potential side effect of this medication?

Choice A reason: The ABG results of pH 7.21, PaCO2 36, HCO3 14 indicate metabolic acidosis, which is common in patients with end-stage kidney disease (ESKD). In ESKD, the kidneys lose their ability to excrete acid and maintain bicarbonate levels, leading to an accumulation of acid in the blood. This condition results in a low pH (acidic), normal PaCO2 (as the respiratory system attempts to compensate), and low HCO3 (bicarbonate).

Choice B reason: The ABG results of pH 7.50, PaCO2 29, HCO3 22 indicate respiratory alkalosis, which is not typically associated with ESKD. Respiratory alkalosis occurs when there is excessive exhalation of carbon dioxide, leading to a higher pH (alkaline). This condition is more likely to be seen in situations such as hyperventilation, anxiety, or certain lung diseases.

Choice C reason: The ABG results of pH 7.47, PaCO2 45, HCO3 33 indicate metabolic alkalosis, which is not typically associated with ESKD. Metabolic alkalosis occurs when there is an excess of bicarbonate or a loss of acid. This condition can result from factors such as vomiting, diuretic use, or excessive antacid consumption. It is not a common finding in patients with ESKD.

Choice D reason: The ABG results of pH 7.31, PaCO2 48, HCO3 24 indicate respiratory acidosis, which is not typically associated with ESKD. Respiratory acidosis occurs when there is an accumulation of carbon dioxide due to impaired respiratory function. This condition is more likely to be seen in chronic obstructive pulmonary disease (COPD) or other respiratory disorders. It is not a common finding in patients with ESKD.

Choice A reason: The statement that young people do not have to worry about heart failure, just older people, is incorrect. While heart failure is more common in older adults, it can occur at any age, particularly in individuals with underlying health conditions or risk factors.

Choice B reason: Progressive kidney failure contributes to the development and severity of heart failure. Kidney function and heart function are closely related. When the kidneys are not working properly, they can contribute to fluid retention, increased blood pressure, and additional strain on the heart, leading to heart failure.

Choice C reason: The elderly patient using cocaine as a teenager and complaining of occasional anxiety is less relevant to the immediate risk factors for developing heart failure. While past cocaine use can have long-term cardiovascular effects, occasional anxiety is not a significant contributing factor to heart failure.

Choice D reason: The patient taking 20mg of losartan every day and having a potassium level of 3.8 mEq/L is relevant to managing their heart condition but does not directly address the development of heart failure. Losartan is a medication used to manage blood pressure and heart failure, and the potassium level is within the normal range.
