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 C
Explanation
Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). They work by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.
Choice A is wrong because nitroglycerin transdermal patches cannot be used to treat an attack of angina once it has begun. They can only be used to prevent attacks of angina. If you have chest pain, you should use another form of nitroglycerin, such as sublingual tablets or spray.
Choice B is wrong because headache is a common side effect of nitroglycerin transdermal patches and does not mean that you should stop using them. However, you should tell your doctor if the headaches are severe or do not go away. You may also take acetaminophen to relieve the headache.
Choice D is wrong because you do not need to cover the patch with dry gauze when taking a shower. You may shower while you are wearing a nitroglycerin skin patch. If a patch loosens or falls off, replace it with a fresh one.
Correct Answer is A
Explanation
This is because the umbilicus is a potential site of infection and should be avoided when administering subcutaneous heparin.
Choice B is wrong because massaging the site after administering the medication can cause bruising and hematoma formation.
Choice C is wrong because a 21-gauge needle is too large for subcutaneous injection and can cause tissue trauma and bleeding.
A smaller needle, such as 25- or 27-gauge, should be used.
Choice D is wrong because aspirating before injecting the medication can increase the risk of hematoma formation and is not recommended for subcutaneous heparin.
