Patient and priorities
79-year-old man, hospital day 2 with acute decompensated heart failure. Heart failure with preserved ejection fraction, LVEF 55% on last year’s echo; atrial fibrillation on apixaban; high blood pressure; chronic kidney disease, stage 3a. No known drug allergies. Ten days of growing breathlessness and leg swelling, after a week away for a family wedding: restaurant meals most days, and he skipped his furosemide 40 mg on 4 travel days to avoid bathroom stops. Lives with his wife in a second-floor apartment with an elevator. Before this, walked 2 blocks and did his own shopping. Priority order: 1. Excessive fluid volume, because fluid in his lungs is affecting his breathing and oxygen now. 2. Decreased activity tolerance, which will ease as the fluid comes off, and decides when he can go home. His priority: “I want to sleep in a bed again, not a chair.” Covered elsewhere: the fall prevention bundle, and the skin care plan for a Braden score of 16.
Excessive fluid volume: assessment and diagnosis
Subjective: “I can’t lie down. I’ve been sleeping in my recliner for a week.” Breathless walking the 8 m to the bathroom; legs feel “tight and heavy.” Objective, 07:30: T 36.8 °C (98.2 °F), HR 94 and irregular, BP 148/82, RR 24, SpO2 91% on room air and 95% on 2 L/min by nasal cannula. Crackles in both lungs from the bases to the mid-back. Neck veins distended to the jaw with the head of the bed at 45 degrees. Pitting edema 3+ to the knees in both legs; sacral edema. Weight at 06:00 on the standing scale, after voiding: 89.0 kg (196.2 lb), down from 90.2 kg (198.9 lb) on admission. Intake 1,150 mL and output 2,350 mL in the last 24 hours. Labs at 05:00: sodium 134 mmol/L, potassium 3.6 mmol/L, creatinine 1.4 mg/dL (124 µmol/L). Chest X-ray yesterday: congestion, and small effusions on both sides. Baseline: dry weight 84.0 kg (185.2 lb) at his August heart failure clinic visit; creatinine 1.3 mg/dL (115 µmol/L). Diagnosis: Excessive fluid volume related to high sodium intake and missed diuretic doses, with heart failure as the associated condition, as evidenced by a weight 5.0 kg above his dry weight, 3+ edema, crackles to the mid-back, distended neck veins, needing to sleep upright, and SpO2 91% on room air.
Excessive fluid volume: outcomes
Goal: back to his dry weight and breathing comfortably, with a plan to stay there at home. Outcome 1: net fluid balance at least 1 L negative each 24 hours while on IV furosemide, by intake and output totals. Outcome 2: by 06:00 on hospital day 4, weight 87.0 kg (191.8 lb) or lower on the same scale. Outcome 3: by hospital day 3, SpO2 92% or higher on room air at rest, and sleeping in bed with the head of the bed at 30 degrees or less. Outcome 4: by discharge, he and his wife will show how to weigh him and log it, and name when to call the clinic. Patient agrees: yes; outcome 3 is his own goal.
Excessive fluid volume: interventions and rationale
Monitor: weight at 06:00 daily on the same standing scale, after voiding, before breakfast, in a hospital gown. Rationale: 1 kg of weight change is about 1 L of fluid, the most reliable bedside measure of fluid loss. Monitor: strict intake and output, totaled each shift; lungs, breathing rate, SpO2, and edema every 4 hours; BP and dizziness on standing before each furosemide dose. Rationale: shows whether diuresis is working, and whether it has gone too far; low BP or dizziness means a call before the dose. Monitor: potassium, sodium, and creatinine each morning, as ordered; call for potassium below 3.5 mmol/L or a creatinine rise of 0.3 mg/dL (27 µmol/L) or more. Rationale: furosemide washes out potassium, and low potassium raises the risk of dangerous heart rhythms; a rising creatinine can mean the kidneys are getting too little blood flow. Nursing care: head of the bed at 45 degrees or more, or sitting in the chair; oxygen adjusted to the ordered SpO2 target; fluid limit of 1.5 L a day as ordered, split with him into 600 mL by 16:00, 600 mL by 22:00, and 300 mL overnight; mouth care, and ice chips counted in his intake, for thirst; turn every 2 hours and check heels and sacrum. Rationale: sitting up lets the lungs expand; a split he chose is easier to keep to; swollen skin breaks down easily. Ordered treatments: furosemide 40 mg IV twice daily at 08:00 and 16:00; potassium replaced per the order; 2 g sodium diet. Rationale: a loop diuretic clears sodium and water through the kidneys, and giving the second dose by 16:00 means fewer trips to the bathroom at night. Teaching: daily weights at home; reading sodium on labels and restaurant menus; taking furosemide on travel days, with a plan for bathroom stops; call the clinic for a gain of more than 1 kg (2 lb) in a day or 2 kg (5 lb) in a week. Rationale: this admission came from salty meals and skipped doses, both things he can change. Collaboration: hospitalist for diuretic doses and call limits; dietitian before discharge; pharmacist to check his medicines; heart failure clinic visit within 7 days of discharge. Rationale: the first weeks after a heart failure admission carry the highest risk of coming back.
Excessive fluid volume: evaluation
Evaluated on hospital day 3 at 07:00. Weight 87.6 kg (193.1 lb), down 1.4 kg in 24 hours. Net balance −1,350 mL. Crackles at both bases only. Oxygen off since 22:00; SpO2 93% on room air at rest at 06:00. Slept in bed with the head of the bed at 30 degrees: “First night in a bed in over a week.” Edema 2+ to mid-shin. BP 128/74; no dizziness on standing. Potassium 3.3 mmol/L at 05:00: reported to the hospitalist at 06:15, replaced by mouth per the order, recheck at 14:00. Creatinine 1.5 mg/dL (133 µmol/L), a rise of 0.1. Outcome 1 met. Outcome 2 progressing: 0.6 kg to go by day 4. Outcome 3 met. Outcome 4 started: he weighed himself with the nurse this morning and wrote it in his log. Decision: continue. At rounds, the team kept IV furosemide for 1 more day, with a plan to switch to oral tomorrow if his weight keeps falling.
Decreased activity tolerance: assessment and diagnosis
Subjective: “Walking to the bathroom feels like climbing a hill.” Breathlessness 7 on the 0 to 10 Borg scale after the walk. Objective, 09:30, walking 8 m (26 feet) to the bathroom with a walker on 2 L/min of oxygen: HR 94 to 121, SpO2 95% to 89%, RR 30; stopped twice to rest; back to resting values after 6 minutes. Baseline: walked 2 blocks and did his own shopping until these 10 days. Diagnosis: Decreased activity tolerance related to fluid in the lungs and limited heart reserve, as evidenced by breathlessness 7/10 and a heart rate rise of 27 beats on an 8 m walk, SpO2 falling to 89%, and needing to stop twice.
Decreased activity tolerance: outcomes
Goal: walking on the unit, then at home, without getting badly out of breath. Outcome 1: by hospital day 4, he will walk 30 m (98 feet) in the hallway with a walker, 3 times a day, with his heart rate no more than 20 beats above resting, SpO2 90% or higher, and breathlessness 4/10 or lower. Outcome 2: by discharge, he will use 2 ways to save energy at home, chosen with him: sitting to wash and dress, and resting for 30 minutes after meals. Patient agrees: “If I can get down to the mailbox, I’ll be happy.”
Decreased activity tolerance: interventions and rationale
Monitor: heart rate, SpO2, breathing rate, and breathlessness before, during, and 3 minutes after each walk; stop and rest if his heart rate rises more than 20 above resting, SpO2 falls below 90%, or he has chest pain, dizziness, or new palpitations. Rationale: keeps each walk safe, and shows his tolerance improving as the fluid comes off. Nursing care: walks at 10:00, 14:00, and 18:00, starting at 10 m and adding 5 m a walk when the last one stayed within limits; care grouped so he rests for 60 minutes after meals and before each walk; washing seated at the sink, and a shower chair. Rationale: short, frequent walks build tolerance without exhausting him, and sitting lowers the oxygen his heart and lungs must supply. Teaching: pace tasks through the day, sit for grooming, and stop to rest before he gets breathless. Rationale: these habits let him do more at home with less breathlessness. Collaboration: physiotherapy assessment today for the walker and a walking plan. Rationale: confirms the right aid and a safe distance before discharge.
Decreased activity tolerance: evaluation
Evaluated on hospital day 3 at 11:00. Day 2: walked 10 m at 10:00, 15 m at 14:00, and 20 m at 18:00, on 2 L/min of oxygen, within limits each time. Day 3 at 10:00, on room air: 25 m (82 feet) with the walker; heart rate 86 to 104, a rise of 18; SpO2 91%; breathlessness 4/10; back to resting values in 3 minutes. Washed seated at the sink this morning with setup only. Outcome 1 progressing: 25 of 30 m, within all limits. Outcome 2 progressing: sits to wash; rest after meals not yet tried. Physiotherapy cleared him for hallway walks with nursing staff. Decision: continue, with the next walk at 30 m at 14:00. Discharge planning started for hospital day 4 or 5.
