A nurse is preparing to administer megestrol 200 mg PO to a client. Available is megestrol oral suspension 40 mg/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.)
The Correct Answer is ["5"]
To calculate the dose of megestrol oral suspension for a client, the nurse needs to use the following formula: Dose (mL) = Ordered dose (mg) / Concentration (mg/mL).
In this case, the ordered dose is 200 mg and the concentration is 40 mg/mL. Therefore, the dose in mL is:
Dose (mL) = 200 mg / 40 mg/mL
Dose (mL) = 5 mL
The nurse should administer 5 mL of megestrol oral suspension to the client.

Correct Answer is ["3"]
Explanation
To calculate the dose of pyrazinamide for a client with tuberculosis, the nurse needs to convert the client's weight from pounds to kilograms and then multiply it by the prescribed dose of 20 mg/kg.
One kilogram is equal to 2.2 pounds, so the client's weight in kilograms is 165 / 2.2 = 75 kg.
The dose of pyrazinamide in milligrams is 75 x 20 = 1500 mg.
The nurse has pyrazinamide tablets of 500 mg each, so the number of tablets needed is 1500 / 500 = 3.
The nurse should administer three tablets of pyrazinamide to the client.
Correct Answer is C
Explanation
A. Fentanyl 25 mcg/hr transdermal patch:
Fentanyl is a potent opioid used for pain management.
The specific concern here is the dosage of 25 mcg/hr. This is a potent dose, and any questions or uncertainties about the appropriateness of this dosage for the specific patient should be clarified with the prescribing provider. Dosages of opioids, especially potent ones like fentanyl, need to be carefully considered to prevent adverse effects, including respiratory depression.
B. Meloxicam 15 mg PO daily:
Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation.
This prescription is straightforward and commonly used. It is a standard dosage for meloxicam. However, the nurse should still ensure that the patient does not have any contraindications or allergies to NSAIDs.
C. Regular insulin 8 units subcutaneous before meals:
Regular insulin 8 units subcutaneous before meals is a vague and potentially dangerous prescription. Regular insulin is a short-acting insulin that lowers blood glucose levels by facilitating the uptake of glucose into the cells. The dose of insulin should be individualized based on the client's blood glucose level, carbohydrate intake, and activity level. The nurse should contact the provider for clarification on how to adjust the dose according to the client's needs.
D. Docusate sodium 200 mg PO at bedtime:
Docusate sodium is a stool softener used to prevent or treat constipation.
This prescription is a standard and commonly used dosage for docusate sodium. However, as with any medication, the nurse should assess the patient's specific needs and medical history, ensuring that there are no contraindications or allergies to this medication.
