The nurse is cаring fоr а 61-yeаr-оld male admitted with an acute myоcardial infarction who underwent a coronary angiogram with two stents placed in the right coronary artery.  Following the coronary angiogram, the client was transferred to the intensive care unit (ICU).  Upon arrival to the ICU, the client's vital signs were stable, and he has been on 0.9%NaCl at 125mL/hr for the past 12 hours and has an order to continue the 0.9%NaCl for another 12 hours.    The nurse assesses the right groin puncture site and notes the site to be clean, dry, intact, and no hematoma is noted.  Bilateral pedal pulses are palpable.  The remainder of the client’s physical assessment is within normal limits. The client's urine output was 250mL/hour upon arrival to the ICU.Five hours after arriving in the ICU, the urine output decreased to 100mL/hour, and every hour continued to decrease.  The current hourly urine output is < 30mL/hr.  The nurse also identifies these vital signs, which are a change from his baseline:  Vital SignValueTemperature98.4’FBlood pressure151/83Heart rate and rhythm112 and sinus tachycardiaRespiratory rate24Oxygen saturation90% on room air The client states that he feels “like I can’t catch my breath.”  He also states that he feels “uneasy.”  Upon assessment of the client, the nurse notes bilateral lower lobe crackles and diminished bilateral anterior breath sounds.  The nurse also assesses mild jugular venous distention and bounding upper and lower extremity pulses.  The nurse notifies the provider, who orders the following diagnostics:  STAT chest x-ray, complete metabolic panel (CMP), complete blood count (CBC), serum osmolality, and urinalysis.  Below are the results of these tests: Chest x-ray:  bilateral lower lobe pulmonary infiltrates newly present compared to the previous chest x-ray and a normal cardiac silhouette  Abnormal Serum Lab values:  LabValueSodium130 mEq/L (135–145 mEq/L)Potassium 5.9 mEq/L (3.5-4.5 mEq/L)BUN60 mg/dL (5 to 20 mg/dL)Creatinine3.0 mg/dL (0.5 to 1.2 mg/dL)GFR 40 mL/min  (125 mL/min)Chloride115 mEq/L (98–108 mEq/L)Calcium7.5 mg/dL (8.5–10.5 mg/dL)Phosphorus6.0 mg/dL (2.5–4.5 mg/dL)Magnesium2.9 mEq/L (1.5-2.0 mEq/L)Bicarbonate20 mEq/L (24–28 mEq/L)Serum osmolality240 mOsm/kg (275-295 mOsm/L)Hemoglobin11.0 g/dL (14-18 g/dL in men and 12-16 g/dL in women)Hematocrit35% (40%-54% for men and 38%-48% for women)  Abnormal Urine Lab Values:Urine osmolality:  1800 mOsm/kg (1200-1500 mOsm/kg)Urine specific gravity:  1.010 (1.001-1.025) Urine protein:  positiveUrine glucose:  positiveBased on the above information, determine if the below interventions would either be anticipated/helpful or contraindicated/not helpful given the client scenario. Match the potential intervention to either anticipated/helpful or contraindicated/not helpful.
