A nurse is preparing to administer pentamidine 4 mg/kg IM to a client who weighs 154 lb. Available is pentamidine 100 mg/mL for injection. 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 ["2.8"]
Convert the patient's weight from pounds to kilograms:
154 lb ÷ 2.2 = 70 kg
Calculate the dose of pentamidine:
4 mg/kg × 70 kg = 280 mg
Determine the volume to be administered:
We have 100 mg/mL concentration of pentamidine.
280 mg ÷ 100 mg/mL = 2.8 mL
Therefore, the nurse should administer 2.8 mL of pentamidine to the client.

Correct Answer is C
Explanation
Choice A reason: This choice is incorrect because stomach distension and constipation are not common side effects of furosemide. They may be related to other causes, such as diet, fluid intake, or medication interactions. The nurse should assess the client's abdominal status and bowel habits and provide appropriate interventions, such as increasing fiber, fluids, or laxatives.
Choice B reason: This choice is incorrect because IV site irritation, redness, and pain are not specific side effects of furosemide. They may be caused by other factors, such as infection, infiltration, or phlebitis. The nurse should inspect the IV site and catheter and change them if needed. The nurse should also monitor the client's vital signs and blood cultures for signs of infection.
Choice C reason: This choice is correct because hearing loss or impairment is a rare but serious side effect of furosemide. It can occur due to damage to the inner ear or the auditory nerve. It may be temporary or permanent, depending on the dose and duration of furosemide therapy. The nurse should stop the infusion of furosemide and notify the provider immediately. The nurse should also assess the client's hearing and balance and provide safety measures.
Choice D reason: This choice is incorrect because frequent urination is an expected effect of furosemide. Furosemide is a diuretic that increases the excretion of water and electrolytes through the urine. It helps to reduce fluid overload and edema in clients with heart failure. The nurse should measure and record the client's intake and output and monitor the client's fluid and electrolyte status.
Correct Answer is ["0.7"]
Explanation
To calculate the amount of epoetin that the nurse should administer, we can use the following formula:
Amount to administer (mL) = (Desired dose in units) / (Amount of drug in 1 mL)
Given:
Desired dose = 7,000 units
Amount of drug in 1 mL = 10,000 units/mL
Now, let's calculate the amount to administer:
Amount to administer (mL) = 7,000 units / 10,000 units/mL
Amount to administer (mL) = 0.7 mL
Rounding to the nearest tenth, the nurse should administer 0.7 mL of the epoetin.
