Answer 7

Correct Answers:

2.1

Rationale :

Formula:

Dose/day = Weight × Dosage

Dose per dose = Dose/day ÷ Frequency

Volume = Dose per dose ÷ Concentration

Calculation:

☑️ Weight = 85 kg

☑️ Daily dose = 85 × 3 = 255 mg/day

☑️ Frequency = 3 doses/day

☑️ Per dose = 255 ÷ 3 = 85 mg

☑️ Concentration = 40 mg/mL

► Volume = 85 ÷ 40

👉🏻 = 2.1 mL

Answer 9

Correct Answers:

Administer a loading dose of 100 mg PO.
Administer the medication with a snack.

Rationale :

🟡 Administer a loading dose of 100 mg PO

🔺 The prescription clearly states an initial dose of 100 mg, which functions as a loading dose to achieve rapid therapeutic levels.

🔺 Loading doses are commonly used in pain management to establish efficacy before transitioning to maintenance dosing.

🔺 The nurse should administer this first dose before initiating the routine 50 mg TID schedule.

🟡Administer the medication with a snack

🔺 Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID), which can cause gastrointestinal irritation if taken on an empty stomach.

🔺 Administering it with a snack or food helps reduce the risk of nausea, dyspepsia, or gastric ulcers.

🔺 The nurse should encourage the client to always take the medication with meals or a snack to promote tolerance.
