A nurse is caring for a client with left-sided heart failure. Which assessment finding should the nurse report to the provider immediately?

nclex-rn practiceNCLEX cardiovascular questions, the way the Next Gen exam asks them
Cardiovascular questions on the NCLEX-RN are almost never simple recall. They ask you to spot the client who is decompensating, decide what to do first, and catch the lab or vital sign that makes a routine order dangerous.
- Heart failure (left vs right)
- MI and chest-pain priorities
- Dysrhythmias and first actions
- Cardiac meds you titrate to a number
The high-yield points, in one place.
- Left = Lungs. Left-sided failure backs up into the lungs (crackles, dyspnea). Right-sided backs up into the body (edema, JVD).
- Digoxin plus low potassium is dangerous. A potassium under 3.5 raises toxicity risk even at a normal dig level. Check potassium and apical pulse first.
- MI priorities: oxygen, ECG, pain relief. A worsening rhythm or a dropping blood pressure outranks a stable abnormal value.
- Check the number before beta blockers and ACE inhibitors. Hold or question them when the BP or heart rate is already low.
- Two right answers means it is testing priority. Airway, breathing, circulation, and the least stable client come first.
