A nurse is planning to administer the first dose of iron dextran intermittent IV bolus for a client who has iron-deficiency anemia. Which of the following interventions should the nurse plan to take?

A) Expect optimum visual acuity to return in 4 to 6 weeks: While some improvement in vision can be noted soon after cataract surgery, optimal visual acuity typically returns within 1 to 2 months. It's important to set realistic expectations for recovery. Telling the patient to expect optimum visual acuity to return in 4 to 6 weeks provides a more accurate timeframe for complete visual recovery.

B) Notify the provider if new floaters persist for more than 3 days: The presence of new floaters can be a sign of complications such as retinal detachment or vitreous hemorrhage. However, patients are generally advised to notify their provider immediately if they notice any new floaters, flashes of light, or a sudden decrease in vision, rather than waiting for three days. Immediate notification can lead to prompt evaluation and treatment if necessary.

C) Take aspirin every 4 to 6 hr for mild discomfort: Aspirin is generally avoided postoperatively due to its blood-thinning properties, which can increase the risk of bleeding. Instead, non-aspirin pain relievers like acetaminophen are usually recommended to manage mild discomfort after cataract surgery, as they do not carry the same risk of bleeding complications.

D) Avoid lifting objects that weigh 9.07 kg (20 lb) or more: Patients are advised to avoid lifting heavy objects and engaging in strenuous activities after cataract surgery to prevent increased intraocular pressure, which can interfere with healing and potentially cause complications such as bleeding or dislocation of the intraocular lens. This instruction helps ensure the safety and proper healing of the surgical site.

A) Diarrhea: Metabolic alkalosis is more likely to be associated with constipation rather than diarrhea. Diarrhea is typically a cause of metabolic acidosis due to the loss of bicarbonate in stool, rather than a result of metabolic alkalosis.

B) Bradycardia: Bradycardia is not a typical manifestation of metabolic alkalosis. Alkalosis can lead to arrhythmias, but it generally does not cause a slow heart rate. Instead, tachycardia might occur as the body compensates for the altered acid-base balance.

C) Tinnitus: Tinnitus is not a common symptom of metabolic alkalosis. It is more often associated with aspirin toxicity or other conditions affecting the auditory system, rather than changes in acid-base balance.

D) Tetany: Tetany is a common manifestation of metabolic alkalosis. The alkalosis causes a decrease in ionized calcium levels, which increases neuromuscular excitability and can lead to muscle cramps, spasms, and tetany. This is a key sign for nurses to monitor as it indicates significant electrolyte disturbances associated with the alkalotic state.
