A nurse is preparing to administer fluoxetine 10 mg PO to an older adult client. Available is fluoxetine oral solution 20 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
Volume to Administer=Desired Dose/Available Concentration × Volume
=10 mg ÷20mg/5mL
= 10/20 × 5mL
= 0.5×5mL
=2.5mL
So, the nurse should administer 2.5 mL.

Correct Answer is A
Explanation
A. 18-month-old who has had watery stools for 3 days: Young children have a higher risk of dehydration and electrolyte imbalances due to their smaller body fluid reserves. Prolonged diarrhea can cause significant fluid and electrolyte loss, leading to potential acid-base imbalances.
B. A client who has a gastrostomy tube: While a gastrostomy tube can present risks for infection and nutritional imbalances, it is typically managed to ensure adequate nutrition and fluid intake, making electrolyte imbalances less likely unless complications arise.
C. 70-year-old with constipation: Constipation alone is less likely to cause significant fluid and electrolyte disturbances compared to prolonged diarrhea, although chronic constipation can lead to other complications such as fecal impaction.
D. 27-year-old with a 24-hour history of nausea and vomiting: A short-term episode of nausea and vomiting can lead to temporary fluid and electrolyte imbalances, but it is less severe compared to several days of diarrhea, particularly in a young child.
Correct Answer is B
Explanation
