When performing a focused cardiac assessment on a newly admitted client, the nurse notes a heave on the left side of the chest. What can a heave signify?
Enlargement of the heart ventricle
Turbulent blood flow
Persistently slow heart beat
Extreme pulse deficit
Coronary artery blockage
The Correct Answer is A
A. A heave (or lift) often indicates ventricular hypertrophy or enlargement, suggesting increased workload on the heart.
B. Turbulent blood flow may lead to murmurs but is not specifically associated with a heave.
C. A persistently slow heartbeat is referred to as bradycardia and does not correlate with a heave.
D. An extreme pulse deficit relates to discrepancies between heartbeats and palpable pulses but is not linked to a heave.
E. Coronary artery blockage would not directly produce a heave; it typically leads to ischemic changes.

A. Curved prongs fitting the nasal passages correctly is appropriate practice for comfort and effective delivery.
B. Padding pressure areas on the skin is a best practice to prevent skin breakdown and is indicative of proper care.
C. An oxygen flow rate of 10 L/min is excessively high for a nasal cannula, which typically accommodates 1-6 L/min; this indicates a need for further education on proper flow rates.
