A nurse is talking with a client who has been taking levothyroxine to treat hypothyroidism.
The nurse should instruct the client to avoid taking which of the following over-the-counter medications within 4 hr of taking levothyroxine?
Fish oil supplements.
Calcium supplements.
Bulk-forming laxatives.
Oral antihistamines.
The Correct Answer is B
Choice A rationale:
Fish oil supplements do not have a known interaction with levothyroxine.
Choice B rationale:
Calcium supplements can interfere with the absorption of levothyroxine. They should be taken at least four hours apart from levothyroxine.
Choice C rationale:
While bulk-forming laxatives can interfere with the absorption of some medications, there’s no specific evidence they interfere with levothyroxine.
Choice D rationale:
Oral antihistamines do not have a known interaction with levothyroxine.

Explanation
To solve this problem, we first need to convert the client’s weight from pounds to kilograms. Then, we can calculate the total amount of amikacin needed. Finally, we can find out how many milliliters of amikacin injection the nurse should administer.
- Convert the client’s weight to kilograms: Given that 1 kg = 2.2 lbs, we can calculate the client’s weight in kilograms as follows:
Weightinkg=WeightinlbsConversionfactor=110lbs2.2lbs/kg≈50kgWeightinkg=ConversionfactorWeightinlbs=2.2lbs/kg110lbs≈50kg
- Calculate the total amount of amikacin needed: The doctor ordered 5 mg of amikacin per kg of body weight, so the total amount of amikacin needed is:
Totalamikacin=Doseperkg×Weightinkg=5mg/kg×50kg=250mgTotalamikacin=Doseperkg×Weightinkg=5mg/kg×50kg=250mg
- Find out how many milliliters of amikacin injection the nurse should administer: Given that the available amikacin injection is 250 mg/mL, we can calculate the volume of injection needed as follows:
Volumeofinjection=TotalamikacinConcentrationofinjection=250mg250mg/mL=1mLVolumeofinjection=ConcentrationofinjectionTotalamikacin=250mg/mL250mg=1mL
So, the nurse should administer 1 mL of amikacin injection.
Correct Answer is D
Explanation
Choice A rationale:
A Positive Chvostek’s sign is a clinical finding associated with hypocalcemia, or low levels of calcium in the blood. It’s not directly related to glyburide usage or symptoms of anxiety and profuse sweating.
Choice B rationale:
Pitting pedal edema occurs when excess fluid builds up in the body, causing swelling. It’s not directly related to glyburide usage or symptoms of anxiety and profuse sweating.
Choice C rationale:
Decreased deep-tendon reflexes or hyporeflexia happens when your skeletal muscles have a decreased or absent reflex response. It’s not directly related to glyburide usage or symptoms of anxiety and profuse sweating.
Choice D rationale:
Decreased blood glucose level or hypoglycemia occurs when your blood sugar (glucose) level falls too low. Glyburide is an oral diabetes medicine that helps control blood sugar levels. Anxiety and profuse sweating are symptoms of low blood sugar.
