A nurse is receiving a medication prescription by telephone from a provider. The provider states, “Administer 6 milligrams of morphine IV push every 3 hours as needed for acute pain.” How should the nurse transcribe the prescription in the client’s medical record?
Morphine 6 mg IV push every 3 hr PRN acute pain.
MS6 mg IV push every 3 hr PRN acute pain.
MSO4 6 mg IV push every 3 hr PRN acute pain.
Morphine 6.0 mg IV push every 3 hr PRN acute pain.
The Correct Answer is A
This is because it uses the full name of the drug, the exact dose, the route of administration, the frequency, and the indication for use. It also avoids any abbreviations that could be confused with other drugs or measurements.
Choice B is wrong because MS is an abbreviation for morphine sulfate which could be mistaken for magnesium sulfate.
Choice C is wrong because MSO4 is an abbreviation for morphine sulfate that could be mistaken for magnesium sulfate.
Choice D is wrong because 6.0 mg could be misread as 60 mg and lead to a tenfold overdose.
Normal ranges for morphine dosage depend on the route of administration, the indication, and the patient’s tolerance and response.
For acute pain, the usual oral dose is 10 to 30 mg every 4 hours as needed. For chronic pain, the usual oral dose is 15 to 30 mg every 8 to 12 hours as needed.
For intravenous (IV) administration, the usual dose is 2.5 to 15 mg every 4 hours as needed.
The morphine equivalent daily dose (MEDD) is a concept that attempts to establish an equivalency in terms of dose when comparing any opioid to morphine.

Correct Answer is B
Explanation
Hot flashes are a common side effect of tamoxifen, which is hormone therapy for breast cancer that blocks the action of estrogen.
Tamoxifen can cause menopause-like symptoms in women, such as irregular or missing periods, vaginal discharge or bleeding, and mood changes. Choice A is wrong because tinnitus (ringing in the ears) is not a known side effect of tamoxifen.
Choice C is wrong because urinary frequency (needing to urinate more often) is not a known side effect of tamoxifen.
Choice D is wrong because constipation (difficulty passing stools) is not a known side effect of tamoxifen.
Correct Answer is A
Explanation
The nurse should instruct the client to avoid drinking beverages while sucking on a nicotine lozenge because this can interfere with the absorption of nicotine and reduce its effectiveness. Some possible explanations for the other choices are:
Choice B is wrong because chewing nicotine gum for 10 minutes before spitting it out is too short.
The recommended duration is at least 30 minutes to allow enough nicotine to be released and absorbed through the lining of the mouth.
Choice C is wrong because changing the nicotine patch every other day is not frequent enough.
The patch should be changed daily and applied to a different skin site to prevent irritation and ensure a steady dose of nicotine.
Choice D is wrong because administering 2 sprays of nicotine nasal spray in each nostril with each dose is too much.
The recommended dose is one spray per nostril, up to five times per hour or 40 times per day.
Using too much nasal spray can cause side effects such as nasal irritation, sneezing, coughing, headache, or nausea.
