Question

Interpret the following orders. Use either administer or give at the beginning of the sentence. Benadryl \(50 \mathrm{mg}\) p.o. stat.

Short answer

Administer Benadryl 50 mg orally immediately.

Step-by-step solution

Analyze the Orders

The order specifies a medication, its dosage, the route of administration, and the timing. Here, Benadryl is the medication, which is ordered in a dosage of 50 mg.

Identify the Route of Administration

The abbreviation 'p.o.' stands for 'per os,' which means 'by mouth' or orally. This indicates how the medication should be given to the patient.

Determine the Timing

The term 'stat' is used, which is a medical term that means the medication should be administered immediately.

Construct the Instruction

Based on the analysis, construct a sentence to convey the order. Start with 'Administer' or 'Give,' followed by the details of the order.

Key concepts

Dosage Calculation

Understanding dosage calculation is a key skill in medical order interpretation. Dosage refers to the amount of medication prescribed to effectively treat the patient, considering their specific medical needs. For instance, in the example exercise, the dosage of Benadryl is set at 50 mg. Calculating the correct dosage involves understanding the prescribed amount based on the doctor's directions, the potency of the drug formulation, and the patient's body requirements. It is crucial for healthcare providers to administer the correct dosage to achieve the desired therapeutic effect without causing any harm. Miscalculations can lead to ineffective treatment or adverse effects.
Here are a few points to keep in mind when calculating dosage:

• Confirm the medication strength on the label.
• Understand the unit conversions, especially between milligrams (mg) and other units.
• Double-check calculations to ensure accuracy.

Route of Administration

The route of administration dictates how a medication is delivered to the patient. This is an integral part of a medical order as it affects the drug's absorption rate, onset of action, and effectiveness.
In the given exercise, the route of administration is indicated as 'p.o.', which stands for 'per os', meaning by mouth. This tells healthcare providers to administer Benadryl orally. Different routes of administration include:

• Oral (p.o.) - taken through the mouth and absorbed in the gastrointestinal tract.
• Intravenous (IV) - injected directly into the bloodstream for rapid action.
• Intramuscular (IM) - injected into a muscle, allowing slower release into the bloodstream.
• Subcutaneous (SC) - injected under the skin.

Choosing the correct route is criticalbecause it influences the drug’s bioavailability and ultimately its effect on the body.

Medication Timing

Medication timing is another essential component of medical order interpretation. It refers to when and how often a medication should be given. Correct timing ensures optimal effectiveness and avoids potential side effects.
In the sample exercise, 'stat' is the term used to indicate that the Benadryl should be administered immediately, signaling urgency. Timing can vary depending on the condition being treated and the medication involved. Here are some common timing instructions you might encounter:

• 'q.d.' (quaque die) - once a day
• 'b.i.d.' (bis in die) - twice a day
• 't.i.d.' (ter in die) - three times a day
• 'q.i.d.' (quater in die) - four times a day
• 'prn' (pro re nata) - as needed

Ensuring medications are administered at the appropriate times helps maintain steady levels in the bloodstream and maximizes therapeutic benefits.
