The healthcare provider prescribes penicillin 200,000 units IM for a client with pneumonia. The available vial is labeled, "Penicillin 500,000 units/mL. How many mL should the nurse administer to this client?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
To determine the correct dosage, the nurse needs to perform a calculation using the information provided. The prescription is for 200,000 units of penicillin, and the available vial concentration is 500,000 units per mL.
To find out how many mLs to administer, the nurse would divide the prescribed units by the concentration of units per mL. This is calculated as 200,000 units divided by 500,000 units/mL, which equals 0.4 mL.

D. Low doses of aspirin can increase uric acid levels by reducing its excretion through the kidneys.
E. While not a direct risk factor, type 2 diabetes is often associated with metabolic syndrome, which includes several risk factors for gout.
F. Research suggests a link between sleep apnea and increased risk of gout, possibly through the effects of intermittent hypoxia on uric acid levels.
G. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are typically used to treat gout attacks and do not generally increase the risk of developing gout. They can, however, affect kidney function with prolonged use.
