NURS 401 Exam 4 Study Questions
and Answers Graded A+ 2026
What are these risk factors for?
CAD
Hypertension
valvular disease
Diabetes Mellitus
Metabolic Syndrome
Obesity
Smoking
High Sodium Intake
Heart Failure
What are the two types of left sided heart failure?
Systolic and diastolic heart failure
What is ejection fraction?
measures the percentage of blood pumped out of the heart with each beat
What is cardiac output?
the amount of blood the heart pumps in one minute
What are these characteristics of?
-Heart Failure with a low ejection fraction- 45% or less
-The heart can't contract enough
-As EF goes down, tissue perfusion and Cardiac Output lessens
-Fluid backs up in the pulmonary system
Systolic Heart Failure
What are these characteristics of?
-Left Ventricle cannot relax to allow proper filling
- Presereved (not bad) Ejection Fraction

Diastolic Heart failure
What are these manifestations of?
Increased HR
Dizziness
Confusion
Pulmonary Congestion
Breathlessness
Oliguria
Fatigue/Weakness
Extremity Heaviness with Exertion
Chest Pain
Cough @ Night
S4 gallop
Pale color/ cool skin
Left-Sided Heart Failure
What is the main cause of right-sided heart failure?
Left sided heart failure
Why does left-sided heart failure lead to right-sided heart?
Because poor pumping on the left leads to fluid buildup and high pressure in the
lungs, which overburdens the right ventricle, ultimately resulting in right-sided
heart failure.
Which side of the heart receives deoxygenated blood from the body and pumps it
to the lungs?
Right side
Which side of the heart receives oxygenated blood from the lungs and pumps it to
the body?
Left side
What are meds given for heart failure?
NURS 401
, NURS 401
Diuretics
Beta Blocker
Ace Inhibitors
Angiotensin Receptor Blockers (ARBS)
Digoxin
What are these signs of?
Cough
Crackles
Wheezes
Blood-tinged sputum
Tachynpea
Pulmonary congestion
What is a tell-tale sign of pulmonary congestion?
Blood-tinged sputum
Which side of heart failure has more respiratory symptoms?
Left sided
What is right sided heart failure?
Right ventricle cannot empty (weak) therefore there is an increase in volume and
pressure
What are other causes of right sided heart failure besides left ventricle failure?
COPD, ARDS, and Pulmonary HTN
(Pulmonary problems)
What are these clinical manifestations of?
Weight gain
Peripheral Edema
Ascites
Hepatomegaly
Diuresis
Jugular Vein Enlargement
Complaints of GI distress
