A nurse is preparing to administer lithium 300 mg PO every 8 hr. Available is lithium carbonate 150 mg capsules. How many capsules should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
2 capsules
To calculate the number of capsules, use the formula:
capsules = (desired dose in mg / available dose in mg) x 1 capsule
Plug in the given values:
capsules = (300 mg / 150 mg) x 1 capsule
Simplify and solve:
capsules = 2 x 1 capsule
capsules = 2 capsules
Round to the nearest whole number and add a leading zero if needed:
capsules = 2 capsules

Correct Answer is D
Explanation
Oral candidiasis, also known as thrush, is a fungal infection of the mouth caused by Candida albicans. It is a common adverse effect of inhaled corticosteroids, such as fluticasone, which can suppress the normal flora of the oral cavity and create a favorable environment for fungal growth. It manifests as white patches or plaques on the tongue, palate, or cheeks that can be scraped off.
a) Polyuria, or excessive urination, is not an adverse effect of fluticasone. It can be caused by diabetes mellitus, diabetes insipidus, diuretics, or kidney disease.
b) Hypoglycemia, or low blood glucose level, is not an adverse effect of fluticasone. It can be caused by
insulin overdose, oral hypoglycemic agents, alcohol intake, or prolonged fasting.
c) Hypertension, or high blood pressure, is not an adverse effect of fluticasone. It can be caused by stress, obesity, smoking, salt intake, or kidney disease.
