The healthcare provider prescribes enoxaparin sodium 80 mg subcutaneously twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL'. How many mL should the nurse administer?

(Enter numeric value only. If rounding is required, round to the nearest tenth.)

Choice A reason: Using a Snellen chart to assess visual acuity is not a direct measure of the effectiveness of pilocarpine, which is used to lower intraocular pressure by constricting the pupil and increasing aqueous humor outflow. Visual acuity may be affected by other factors, such as refractive errors, cataracts, or macular degeneration.

Choice B reason: Checking the amount of drainage from each eye is not a relevant action for evaluating the effectiveness of pilocarpine, which does not affect tear production or drainage. Excessive or abnormal eye drainage may indicate an infection, allergy, or injury.

Choice C reason: Palpating the eyelids for decreased swelling is not a useful action for evaluating the effectiveness of pilocarpine, which does not cause or reduce eyelid swelling. Eyelid swelling may be caused by inflammation, infection, allergy, or trauma.

Choice D reason: Reviewing eye pressure measurements is the correct action for evaluating the effectiveness of pilocarpine, which is used to lower intraocular pressure in patients with open-angle glaucoma. High intraocular pressure can damage the optic nerve and cause vision loss. Pilocarpine reduces intraocular pressure by constricting the pupil and increasing aqueous humor outflow.

Choice A reason: Eliminating use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, is an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that stabilizes mood and prevents manic episodes. NSAIDs can increase the blood levels of lithium and cause toxicity, which can manifest as nausea, vomiting, tremors, confusion, or seizures.

Choice B reason: Monitoring blood glucose levels daily is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not affect the blood sugar levels or the risk of diabetes. Blood glucose levels may be important for the general health of the client, but they are not related to lithium therapy.

Choice C reason: Notifying healthcare provider prior to dental procedures is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interact with local anesthetics or antibiotics that may be used during dental procedures. However, the client should inform the dentist about their medical history and medications, as a precaution.

Choice D reason: Avoiding consuming all foods that contain iodine is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interfere with the thyroid function or the metabolism of iodine. Iodine is an essential nutrient that is found in many foods, such as seafood, dairy products, eggs, and iodized salt. Avoiding iodine can cause deficiency and lead to goiter or hypothyroidism.
