A nurse is reviewing a prescription for nystatin 200,000 units in a troche PO 4 times per day. How should the nurse interpret this prescription?

Withhold oral intake until the troche dissolves in the client's mouth.

Give the client two troches in the morning and two troches in the evening.

Tell the client to keep the troche under the tongue for 5 min before swallowing it

Instruct the client to swallow the troche with 240 mL (8 oz) water.

Answer and Explanation

The Correct Answer is A

A troche is a type of lozenge that is designed to dissolve slowly in the mouth to release medication over time.

The nurse should instruct the client to place the troche in their mouth and allow it to dissolve slowly without chewing or swallowing it.

The client should also avoid eating or drinking anything until the troche has completely dissolved to ensure maximum absorption of the medication.

The other options are incorrect because they do not accurately describe how a troche should be taken.

Option b is incorrect because it does not specify how the troches should be taken, only the timing of the doses.

Option c is incorrect because it instructs the client to keep the troche under the tongue for only 5 minutes before swallowing it, which may not allow enough time for the troche to dissolve completely and release its medication.

Option d is incorrect because it instructs the client to swallow the troche with water, which would prevent the

medication from being absorbed through the mucous membranes in the mouth and may reduce its eﬀectiveness.

Correct Answer is ["0.019"]

Explanation

19,000 mcg of haloperidol is equivalent to 0.019 g.

To calculate this, use the conversion factor that 1 g is equivalent to 1,000,000 mcg. So, 19,000 mcg * (1 g / 1,000,000 mcg) = 0.019 g.

Correct Answer is ["30"]

Explanation

To calculate this, first convert the child's weight from pounds to kilograms: 66 lb * (1 kg / 2.2 lb) = 30 kg. Then, calculate the total daily dose of dexamethasone in mg: 0.2 mg/kg/day * 30 kg/day = 6 mg/day.

Since the daily dose is divided into two doses, calculate the dose per administration: 6 mg/day / 2 doses/day = 3 mg/dose.

Finally, divide the dose in mg by the concentration of the dexamethasone elixir to find the volume to administer: 3 mg / (0.5 mg/5 mL) = 30 mL/dose.
