A nurse is preparing to administer phenytoin 200 mg via a gastrostomy tube. Available is phenytoin oral suspension 125 mg/5 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["8"]

To calculate the amount of phenytoin oral suspension to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (mg) / Available dose (mg/mL))

Plugging in the given values:

Amount to administer (mL) = (200 mg / 125 mg/5 mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (200 mg / 125 mg/5 mL) = (200 / 125) 5 = 8

So, the nurse should administer 8 mL of phenytoin oral suspension via the gastrostomy tube.

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.

Correct Answer is ["150"]

Explanation

To calculate the IV pump rate for the 0.9% sodium chloride 1,200 mL IV to infuse over 8 hours, we can use the following formula:

IV pump rate (mL/hr) = Total volume (mL) / Time (hr)

Using the given values:

Total volume = 1,200 mL

Time = 8 hours

Plugging these values into the formula:

IV pump rate = 1,200 mL / 8 hr

IV pump rate = 150 mL/hr

So, the nurse should set the IV pump to deliver 150 mL/hr to infuse the 1,200 mL of 0.9% sodium chloride over 8 hours.
