The physician orders Amoxil 500mg PO BID. The Amoxil is, supplied 250mg/10mL. How many mL will the nurse administer?
The Correct Answer is ["20"]
Rationale:
To calculate the volume to administer, use the formula:
(Desired dose ÷ Dose on hand) × Volume on hand = Volume to administer
(500 mg ÷ 250 mg) × 10 mL = 2 × 10 mL = 20 mL
The nurse will administer 20 mL per dose.

Correct Answer is D
Explanation
Rationale:
A. Increased bowel sounds are more commonly associated with conditions like diarrhea or early bowel obstruction, not hypokalemia.
B. Numbness in the feet is more characteristic of peripheral neuropathy or hypocalcemia, not a typical early sign of hypokalemia.
C. A positive Trousseau's sign indicates hypocalcemia, not hypokalemia.
D. Reports of fatigue are a common and early manifestation of hypokalemia due to muscle weakness and decreased cellular function resulting from low potassium levels.
Correct Answer is D
Explanation
Rationale:
A. Hemoglobin is important for evaluating oxygen-carrying capacity and detecting anemia, but spironolactone does not directly affect hemoglobin levels. This value is not a priority for monitoring the effects of spironolactone.
B. Cholesterol levels are relevant for assessing cardiovascular risk, but spironolactone does not significantly impact lipid profiles. Therefore, total cholesterol is not the most important lab to monitor for this medication.
C. TSH is used to evaluate thyroid function. Spironolactone does not influence thyroid hormones or TSH levels, so this value is unrelated to the medication’s expected effects or complications.
D. Spironolactone is a potassium-sparing diuretic. It works by antagonizing aldosterone in the distal tubule, leading to retention of potassium. This can result in hyperkalemia, especially in older adults or those with renal impairment. Monitoring serum potassium is essential to prevent life-threatening arrhythmias and other complications.
