The healthcare provider prescribes an IV solution of clindamycin 850 mg in 75 ml of D5W to infuse over 30 minutes.

The drop factor is 15 gtt/mL. The nurse should regulate the IV to deliver how many gtt/minute? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Choice A rationale:

Radiation exposure to the eye is a serious condition that requires immediate medical attention. However, it is not a contraindication for ophthalmic ketorolac. In fact, ketorolac may be used to treat pain and inflammation associated with radiation exposure to the eye.

Ophthalmic ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the production of prostaglandins, which are substances that cause inflammation and pain.

Radiation exposure can damage the cells of the eye, leading to inflammation and pain. Ketorolac can help to reduce these symptoms.

However, it is important to note that ketorolac does not address the underlying cause of radiation exposure, and further treatment may be necessary.

Choice B rationale:

Corneal abrasion is a scratch on the surface of the cornea, the clear outer layer of the eye. It is a common eye injury that can be caused by a variety of factors, such as getting poked in the eye, rubbing the eye too hard, or wearing contact lenses for too long.

Ophthalmic ketorolac is contraindicated in patients with corneal abrasions because it can delay healing and increase the risk of infection.

This is because ketorolac inhibits the production of prostaglandins, which are involved in the healing process. Prostaglandins also play a role in fighting infection.

Therefore, using ketorolac in a patient with a corneal abrasion could potentially lead to a more serious infection.

Choice C rationale:

Chemical burn to the eye is a serious injury that requires immediate medical attention. Ophthalmic ketorolac is not typically used to treat chemical burns to the eye.

This is because ketorolac is not effective in reducing inflammation caused by chemical burns. In addition, ketorolac can potentially worsen the injury by delaying healing.

Choice D rationale:

Foreign body in the eye is a common eye injury that can be caused by a variety of objects, such as dust, sand, or metal shavings. Ophthalmic ketorolac is not typically used to treat foreign bodies in the eye.

This is because ketorolac will not help to remove the foreign body from the eye. In addition, ketorolac can potentially worsen the injury by delaying healing.

Step 1: Identify the desired dose and the available concentration. Desired dose: 500 mg of vancomycin

Available concentration: 500 mg per 100 ml

Step 2: Determine the volume needed to deliver the desired dose.

Since the available concentration is 500 mg per 100 ml, no further calculation is required. The volume needed to deliver 500 mg of vancomycin is already 100 ml.

Step 3: Calculate the infusion rate in mL/hr.

The medication needs to be administered over 1 hour.

Therefore, the infusion pump should be set to deliver the 100 ml of solution over 1 hour. Infusion rate = 100 ml / 1 hour = 100 mL/hr.
