A nurse is preparing to administer morphine 7.5 mg subcutaneous. Available is morphine injection 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.75"]
To calculate the volume of morphine injection that the nurse should administer, we can use the following steps:
Determine the volume to be administered:
We have a concentration of 10 mg/mL.
7.5 mg ÷ 10 mg/mL = 0.75 mL
Therefore, the nurse should administer 0.75 mL of morphine injection subcutaneously.

Correct Answer is ["48"]
Explanation
To calculate the amount of gentamicin the nurse should administer in milliliters (mL) for a client who weighs 210 lb, we can use the following steps:
Given:
Client's weight: 210 lb
Gentamicin dose: 5 mg/kg
Available concentration: 10 mg/mL
Step 1: Convert the client's weight from pounds (lb) to kilograms (kg)
Client's weight in kg = Client's weight in lb / 2.2
Client's weight in kg = 210 lb / 2.2
Client's weight in kg ≈ 95.45 kg
Step 2: Calculate the total dose of gentamicin required
Total dose = Client's weight in kg × Gentamicin dose
Total dose = 95.45 kg × 5 mg/kg
Total dose = 477.25 mg
Step 3: Calculate the volume of gentamicin to be administered in mL
Volume = Total dose / Concentration
Volume = 477.25 mg / 10 mg/mL
Volume ≈ 47.725 mL
Rounding to the nearest whole number:
Volume ≈ 48 mL
Therefore, the nurse should administer approximately 48 mL of gentamicin via intermittent IV bolus to the client who weighs 210 lb.
Correct Answer is C
Explanation
Choice A reason: This is incorrect. Dry cough and nose bleed are not common side effects of gemfibrozil. They may indicate other conditions, such as allergies, infections, or bleeding disorders.
Choice B reason: This is incorrect. Constipation and dry skin are not common side effects of gemfibrozil. They may be caused by dehydration, dietary factors, or other medications.
Choice C reason: This is correct. Abdominal pain and jaundice are serious side effects of gemfibrozil. They may indicate liver damage, which can be fatal if not treated promptly. The client should report these symptoms to the prescriber immediately.
Choice D reason: This is incorrect. Hirsutism and flatulence are not common side effects of gemfibrozil. They may be associated with hormonal imbalances, digestive disorders, or other causes.
