A nurse is caring for an older adult client who has heart failure. Which of the following findings should the nurse report to the provider?
Chest x-ray showing cardiomegaly
PaCO2 55 mmHg
Potassium level 4.5 mEq/L
Urinary output of 1,000 mL in 12 hr
The Correct Answer is B
Choice A reason: Chest x-ray showing cardiomegaly is not a new finding for the client who has heart failure, as it indicates enlargement of the heart due to increased workload and pressure on the cardiac chambers.
Choice B reason: PaCO2 55 mmHg is an abnormal finding for the client who has heart failure, as it indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pulmonary edema, which is a complication of heart failure that impairs gas exchange and ventilation.
Choice C reason: Potassium level 4.5 mEq/L is a normal finding for the client who has heart failure, as it indicates adequate electrolyte balance and renal function.
Choice D reason: Urinary output of 1,000 mL in 12 hr is a normal finding for the client who has heart failure, as it indicates adequate fluid status and cardiac output.

Correct Answer is ["1.5"]
Explanation
The correct answer is 1.5 mL. Here is the explanation:
To calculate the amount of mL to administer, the nurse should use the following formula:
mL = (units ordered / units available) x mL available
Plugging in the values from the question, we get:
mL = (15,000 / 10,000) x 1
mL = 1.5 x 1
mL = 1.5
Therefore, the nurse should administer 1.5 mL of heparin with each dose.
Correct Answer is D
Explanation
Choice A reason: PaO2 85 mmHg is within the normal range of 80 to 100 mmHg and does not indicate any hypoxemia or oxygen deficiency.
Choice B reason: pH 7.47 is within the normal range of 7.35 to 7.45 and does not indicate any acid-base imbalance.
Choice C reason: HCO3 25 mEq/L is within the normal range of 22 to 26 mEq/L and does not indicate any metabolic disturbance.
Choice D reason: PaCO2 55 mmHg is above the normal range of 35 to 45 mmHg and indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pneumonia, which can impair gas exchange and ventilation.
