A nurse is reviewing the laboratory values of a client who is taking atorvastatin. Which of the following laboratory values indicates the treatment has been effective?

Urine specific gravity 1.020.

BUN 15 mg/dL.

LDL 120 mg/dL.

Blood glucose 90 mg/dL.

Answer and Explanation

The Correct Answer is C

Atorvastatin is a medication that belongs to a group of drugs called statins. It is used to lower blood levels of “bad” cholesterol (low-density lipoprotein, or LDL), to increase levels of “good” cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood). The treatment has been effective if the LDL level is reduced, as high LDL levels can increase the risk of heart disease and stroke. A normal range for LDL is less than 100 mg/dL.

Choice A is wrong because urine specific gravity is a measure of how concentrated the urine is, not how much cholesterol is in the blood. A normal range for urine specific gravity is 1.005 to 1.0304.

Choice B is wrong because BUN (blood urea nitrogen) is a measure of how well the kidneys are working, not how much cholesterol is in the blood. A normal range for BUN is 7 to 20 mg/dL.

Choice D is wrong because blood glucose is a measure of how much sugar is in the blood, not how much cholesterol is in the blood.

A normal range for blood glucose is 70 to 100 mg/dL.

Correct Answer is A

Explanation

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.

A. Rinse your child’s mouth following administration. B. A spacer will make it easier to use the device. C. Soak the inhaler in water after use. D. Have your child take one inhalation as needed for shortness of breath. E. Shake the device prior to administration.

Correct Answer is ["A","B"]

Explanation

Fluticasone is an inhaled steroid that prevents the symptoms of asthma by decreasing inflammation in the airways. It is not used to treat a sudden asthma attack.

Some additional information to explain why the other choices are wrong are:

Choice C is wrong because soaking the inhaler in water after use can damage the device and affect its performance.

Choice D is wrong because fluticasone is not a rescue inhaler that can be used as needed for shortness of breath.It is a controller inhaler that should be used regularly as prescribed by the doctor.

Choice E is wrong because shaking the device prior to administration is not necessary for a fluticasone metered-dose inhaler (MDI).However, it is recommended for fluticasone inhalation powder (Flovent Diskus). Some normal ranges that may be applicable are:

The usual dose of fluticasone MDI for adults and children 12 years and older is 55 to 232 mcg twice a day.The usual dose of fluticasone MDI for children 4 to 11 years old is 30 mcg twice a day. The maximum dose of fluticasone MDI for adults and children 12 years and older is 1000 mcg twice a day.
