A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg 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 ["500"]
To calculate the dose of erythromycin per administration, you can follow these steps:
- Determine the total daily dose: 2 g.
- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =
0.5 g per dose.
- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.
So, the nurse should administer 500 mg of erythromycin per dose.

Correct Answer is A
Explanation
A. "This medication can cause an increase in appetite." is correct. Amitriptyline is a tricyclic antidepressant (TCA) that commonly causes increased appetite and weight gain as side effects. Clients should be informed of this possibility and encouraged to monitor their diet and weight while taking the medication.
B. "You might experience hair loss while taking this medication." is incorrect. Hair loss is not a common adverse effect of amitriptyline. This side effect is more commonly associated with other medications, such as chemotherapy agents or certain anticonvulsants.
C. "This medication can cause diarrhea." is incorrect. Amitriptyline typically causes constipation rather than diarrhea due to its anticholinergic effects, which slow gastrointestinal motility. Clients should be advised to increase fiber and fluid intake to help manage constipation.
D.While trouble urinating can occur due to anticholinergic effects, urinary frequency is not a commonly reported adverse effect of amitriptyline.
