A nurse is preparing to administer aspirin 650 mg PO every 12 hr. The amount available is aspirin 325 mg tablets. How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A) Absence of proteinuria:

Chronic glomerulonephritis often involves damage to the glomeruli in the kidneys, which can lead to the leakage of protein into the urine, resulting in proteinuria. The absence of proteinuria would be an unexpected finding in a patient with chronic glomerulonephritis. Therefore, this choice is incorrect.

B) Serum phosphorus 4.0 mg/dL (within expected reference range):

Serum phosphorus levels within the expected reference range are not directly related to chronic glomerulonephritis. While abnormalities in electrolyte levels might occur due to kidney dysfunction, serum phosphorus within the normal range is not a hallmark finding of glomerulonephritis. Therefore, this choice is incorrect.

C) Serum potassium 3.8 mEq/L (within the expected reference range):

Similar to serum phosphorus, serum potassium levels within the normal range are not specific to chronic glomerulonephritis. Kidney dysfunction can indeed affect electrolyte levels, but a serum potassium level within the normal range doesn't provide specific information about glomerulonephritis. Therefore, this choice is incorrect.

D) BUN 50 mg/dL (elevated):

Blood Urea Nitrogen (BUN) is a waste product that is filtered by the kidneys. Elevated BUN levels indicate impaired kidney function, as the kidneys are less efficient at filtering and excreting waste products. Chronic glomerulonephritis can lead to progressive kidney damage, which can result in elevated BUN levels due to decreased filtration and clearance. Therefore, an elevated BUN level is an expected finding in a patient with chronic glomerulonephritis.

A. Levothyroxine

Correct Answer: Levothyroxine should be administered before breakfast.

Explanation: Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. It needs to be taken on an empty stomach, at least 30 minutes before eating, to ensure proper absorption. Food can interfere with its absorption, especially foods containing calcium, iron, and fiber.

B. Digoxin

Incorrect Explanation: Digoxin does not need to be administered before breakfast.

Explanation: Digoxin is a medication used to treat heart conditions like congestive heart failure and atrial fibrillation. It doesn't have specific instructions regarding administration in relation to meals. It's important to administer digoxin consistently at the same time every day, but it doesn't need to be taken specifically before or after breakfast.

C. Divalproex

Incorrect Explanation: Divalproex does not need to be administered before breakfast.

Explanation: Divalproex is used to treat conditions like epilepsy and bipolar disorder. It can be taken with or without food. While taking it with food might reduce the likelihood of stomach upset, there's no requirement to take it specifically before breakfast.

D. Mycostatin Mouthwash

Incorrect Explanation: Mycostatin mouthwash is not related to breakfast timing.

Explanation: Mycostatin is an antifungal medication used to treat fungal infections in the mouth (oral thrush). Its administration is not linked to meal times. It's typically swished around in the mouth and then swallowed or spit out, depending on the specific instructions provided by the healthcare provider.
