Short answer

Answer: Medication orders C (Coumadin 10mg PO) and D (Premarin 0.625 mg P0 daily) need further clarification.

Step-by-step solution

Analyze medication order A

(Darvocet 65mg PO every 4-6 hrs. PRN) "Darvocet" is the brand name of the drug "propoxyphene." The order states "65mg PO every 4-6 hrs. PRN," which means the patient will take 65 mg of the medication by mouth, at an interval of 4-6 hours as needed. This order is clear, and no further clarification is necessary.

Analyze medication order B

(Mysoline 250mg PO TID ) "Mysoline" is the brand name of the drug "primidone." The medication order says "250mg PO TID," which stands for "250 mg by mouth three times a day." This order is also clear and does not need any further clarification.

Analyze medication order C

(Coumadin 10mg PO ) "Coumadin" is the brand name of the drug "warfarin sodium." The medication order reads "10mg PO," which means 10 mg should be taken by mouth. However, the frequency of administration is not specified in this order. Therefore, this medication order needs further clarification.

Analyze medication order D

(Premarin \(.625 \mathrm{mg}\) P0 daily) "Premarin" is the brand name of the drug "conjugated estrogen." The order states "\(.625 \mathrm{mg}\) PO daily," which means the patient will take 0.625 mg of the medication by mouth every day. This order seems clear; however, there is a typo in this order, which is writing "P0" instead of "PO" for "by mouth," so further clarification is needed to confirm the typo.

Identify the medication order that needs further clarification

Based on the analysis of each medication order, medication orders C (Coumadin 10mg PO) and D (Premarin \(.625 \mathrm{mg}\) P0 daily) need further clarification. Order C lacks the administration frequency, and order D contains a typo.
