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: 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.

Choice A reason:

Taking an initial respiratory rate is a necessary action to ensure safety during morphine administration, as morphine can cause respiratory depression, which is a potentially life-threatening side effect. The nurse should monitor the client's respiratory rate and oxygen saturation regularly and report any signs of respiratory distress or hypoxia to the physician. Therefore, choice A is correct.

Choice B reason:

Performing a 12-lead electrocardiogram is not a necessary action to ensure safety during morphine administration, as morphine does not have a significant effect on the cardiac rhythm or conduction. The nurse should monitor the client's heart rate and blood pressure regularly and report any signs of bradycardia, hypotension, or chest pain to the physician. Therefore, choice B is incorrect.

Choice C reason:

Suctioning the client to clear the airway is not a necessary action to ensure safety during morphine administration, as morphine does not cause excessive secretions or bronchospasm that would obstruct the airway. The nurse should assess the client's level of consciousness and gag reflex regularly and report any signs of sedation, confusion, or aspiration to the physician. Therefore, choice C is incorrect.

Choice D reason:

Having a manual resuscitation bag at the bedside is a necessary action to ensure safety during morphine administration, as morphine can cause respiratory depression that may require emergency intervention. The nurse should be prepared to administer oxygen and naloxone (an opioid antagonist) as ordered and perform rescue breathing or cardiopulmonary resuscitation if needed. Therefore, choice D is correct.

Choice E reason:

Asking the client about other medications she takes is a necessary action to ensure safety during morphine administration, as morphine can interact with other drugs that may enhance or reduce its effects or cause adverse reactions. The nurse should review the client's medication history and current medications and report any potential drug interactions or contraindications to the physician. Therefore, choice E is correct.

Choice F reason:

Restraining the client with soft restraints is not a necessary action to ensure safety during morphine administration, as morphine does not cause agitation or delirium that would warrant physical restraint. The nurse should provide a safe and comfortable environment for the client and report any signs of anxiety, hallucinations, or psychosis to the physician. Therefore, choice F is incorrect.
