A nurse is reviewing the medical record of an adult client who has a fever and a prescription for acetaminophen.
Which of the following findings should the nurse identify as a contraindication for receiving this medication?

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.

Raloxifene is a medication used to prevent and treat osteoporosis in postmenopausal women.

Osteoporosis is a condition that causes bones to become thin and weak, increasing the risk of fractures.

Raloxifene belongs to a class of drugs called selective estrogen receptor modulators (SERMs), which mimic the effects of estrogen on bone density. Choice B is wrong because raloxifene may increase the risk of deep-vein thrombosis (DVT), a type of blood clot that forms in a vein deep in the body. DVT can cause pain, swelling, and redness in the affected limb, and can lead to serious complications such as pulmonary embolism (PE), a blood clot in the lung.

Raloxifene should not be used by people who have or had DVT or PE. Choice C is wrong because raloxifene is not used to treat urinary tract infection (UTI), an infection that affects the bladder, kidneys, or ureters. UTI can cause symptoms such as burning or pain when urinating, frequent or urgent urination, blood in the urine, or fever.

UTI is usually treated with antibiotics.

Choice D is wrong because raloxifene is not used to treat hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormone.

Thyroid hormone regulates the body’s metabolism, growth, and development. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, or depression.

Hypothyroidism is usually treated with synthetic thyroid hormone replacement.
