A client receives a prescription for a one-time dose of metronidazole 2 grams by mouth.

The medication is available in 500 mg tablets.

How many tablets should the nurse administer? (Enter numerical value only).

The correct answer is choice D.

When administering ear drops to an adult client with an ear infection, the nurse should keep the patient in a supine position to administer the drops.

This position allows the medication to flow into the ear canal and reach the site of infection.

Choice A is not correct because it is not necessary to swab and shake the bottle before administering the drops.

Choice B is not correct because tilting the head upright would cause the medication to flow out of the ear canal instead of reaching the site of infection.

Choice C is not correct because lowering the edge of the dropper into the canal of the ear could cause injury or discomfort to the patient.

A. 3 mL syringe and a sterile needle.
This is incorrect. A sterile needle is unnecessary for administering an oral medication. Syringes with needles are used for injections, not for measuring or delivering oral medications.

B. One ounce medicine cup.
This is incorrect. While a medicine cup can be used for liquid medications, it is not precise for small volumes such as 2 mL. The graduations on a medicine cup are typically in larger increments, making it difficult to measure accurately.

C. 3 mL syringe.
This is correct. A 3 mL syringe is precise and suitable for measuring a 2 mL dose of a viscous liquid. Syringes provide clear markings, ensuring accurate measurement of small volumes. Additionally, the absence of a needle makes it appropriate for oral administration.

D. Tuberculin syringe.
This is incorrect. Although a tuberculin syringe can accurately measure small doses, it is designed for very small volumes, such as 1 mL or less. A 3 mL syringe is more appropriate for a 2 mL dose.
