Exhibits Considering the provider orders, which should the nurse monitor most closely for possible complications, given the client's history and condition?

A. Famotidine 20mg IV: Famotidine is a histamine-2 receptor antagonist used to reduce stomach acid, typically for stress ulcers. While monitoring is necessary for side effects (e.g., headache or dizziness), it is not as urgent as managing fluid balance in this patient with CHF. B. Placement of sequential compression stockings: The use of sequential compression stockings helps prevent deep vein thrombosis (DVT) in immobilized patients. This is important for the patient’s post-operative recovery, but it is not as vital as monitoring the patient’s fluid status in this CHF and diuresis patient. C. Cefepime 2gm IV every 12 hours: Cefepime is an antibiotic prescribed to treat a suspected infection, indicated by the patient’s fever and elevated WBC. While monitoring for potential allergic reactions or side effects is important, the fluid management takes precedence due to the patient's underlying CHF. D. Lactated Ringers at 170mL/hr: The patient has a history of congestive heart failure (CHF), and aggressive fluid resuscitation could exacerbate fluid overload and worsen heart failure symptoms. Close monitoring of fluid status is crucial to avoid complications such as pulmonary edema or worsening CHF.
