CHF Case Study

​

**Introduction:**

In this nursing case study, we will explore the assessment of a patient, Mr. Anderson, who has congestive heart failure (CHF). Your goal is to conduct a comprehensive assessment, including objective and subjective findings, interpret laboratory results, and understand his condition better to provide appropriate care.

 

**Patient Profile:**

Mr. Anderson is a 68-year-old man with a known history of hypertension and coronary artery disease. He presents to the hospital with worsening symptoms of CHF, including shortness of breath, fatigue, and lower extremity edema. He has been compliant with his medications but reports recent weight gain and increased difficulty breathing.

1. **Chief Complaint:**

   - Mr. Anderson's primary complaint is severe shortness of breath, especially when lying flat.

 

2. **History of Present Illness:**

   - He has experienced an increase in shortness of breath over the last two weeks, particularly when lying down.

   - He reports waking up at night gasping for breath, requiring him to sit upright to relieve his symptoms?

   - Mr. Anderson notes a sudden weight gain of 6 pounds over the past week.

 

3. **Past Medical History:**

   - Mr. Anderson has a history of hypertension and coronary artery disease.

   - He underwent coronary artery bypass graft (CABG) surgery five years ago.

   - There is a family history of heart disease.

 

4. **Medication History:**

   - He is taking prescribed medications for hypertension, including ACE inhibitors and beta-blockers, as well as diuretics.

   - He is also taking antiplatelet agents and statins as per his cardiac history.

Multiple Choice

Based on Mr. Anderson's clinical presentation, what lab would likely be ordered?

• BNP

• CBC

• Reticulocyte count

• Witzinger test

1. Vital Signs:

   • Blood Pressure: 160/95 mm Hg

   • Heart Rate: 100 beats per minute

   • Respiratory Rate: 26 breaths per minute

   • Temperature: 98.6°F (oral)

2. General Appearance:

   • Mr. Anderson appears anxious, fatigued, and slightly pale.

3. Cardiovascular Assessment:

   • Jugular venous distention (JVD) is visibly present at 5 cm above the sternal angle.

   • On auscultation, you hear S3 heart sounds.

   • You note an enlarged and displaced point of maximum impulse (PMI) to the left of the midclavicular line in the fifth intercostal space.

   • No heart murmurs are heard.

1. Respiratory Assessment:

   • Mr. Anderson exhibits labored breathing with increased work of breathing.

   • You hear crackles on lung auscultation, primarily in the bases of both lungs.

2. Edema Assessment:

   • Bilateral lower extremity edema is present, with 2+ pitting edema up to the knees.

3. Weight:

   • Mr. Anderson's current weight is 10 pounds higher than his previous weight taken one week ago.

Labs

1. Troponin Level:

   • Troponin I level: 0.04 ng/mL (normal reference range: 0.00 - 0.03 ng/mL)

   • Interpretation: Elevated Troponin I levels suggest myocardial damage, possibly due to acute coronary syndrome (ACS) or cardiac injury.

2. B-type Natriuretic Peptide (BNP) Level:

   • BNP level: 850 pg/mL (normal reference range: <100 pg/mL)

   • Interpretation: Elevated BNP levels indicate increased cardiac stress and are consistent with heart failure.
