ATI CARDIOVASCULAR STUDY GUIDE 2027
QUESTIONS WITH ANSWERS GRADED A+
◉ What can inadequate cardiovascular function lead to? Answer:
Decreased tissue perfusion, hypoxia, fluid accumulation, organ
dysfunction, dysrhythmias, shock, or death.
◉ What vital signs should be assessed in cardiovascular patients?
Answer: Blood pressure, heart rate, respiratory rate, oxygen saturation,
and temperature.
◉ Why is monitoring blood pressure important in cardiovascular
assessment? Answer: Hypotension may indicate decreased cardiac
output.
◉ What does tachycardia often indicate in cardiovascular patients?
Answer: It may be a compensatory response to decreased cardiac output.
◉ What does tachypnea suggest in a patient with cardiovascular issues?
Answer: It may indicate pulmonary congestion or inadequate
oxygenation.
,◉ What are key assessments for peripheral perfusion? Answer:
Peripheral pulses, skin temperature, skin color, capillary refill, sensation,
movement, and pain.
◉ What is a normal capillary refill time? Answer: Generally 2 seconds
or less.
◉ What signs may indicate peripheral arterial disease? Answer: Cool
extremities, weak peripheral pulses, pale skin, delayed capillary refill,
and pain with walking.
◉ What does a sudden loss of a previously palpable peripheral pulse
indicate? Answer: It requires immediate evaluation.
◉ What should be monitored to assess fluid status in cardiovascular
patients? Answer: Daily weight, intake and output, peripheral edema,
lung sounds, jugular venous distention, and urine output.
◉ What does a weight gain of approximately 1 kg indicate? Answer: It
may represent approximately 1 liter of retained fluid.
◉ What is BNP and why is it significant? Answer: BNP stands for B-
type natriuretic peptide, released in response to increased heart wall
pressure, indicating heart failure.
,◉ What BNP level generally makes acute heart failure less likely?
Answer: Less than 100 pg/mL.
◉ What does elevated troponin indicate? Answer: Myocardial injury,
which can be due to myocardial infarction, myocarditis, severe heart
failure, or pulmonary embolism.
◉ What are common causes of hypokalemia? Answer: Loop diuretics,
thiazide diuretics, vomiting, diarrhea, and inadequate potassium intake.
◉ What ECG findings may indicate hypokalemia? Answer: Flattened T
waves, ST depression, and prominent U waves.
◉ What are the manifestations of hyperkalemia? Answer: Muscle
weakness, paresthesias, nausea, palpitations, and dysrhythmias.
◉ What ECG changes may occur with hyperkalemia? Answer: Tall,
peaked T waves, widened QRS complexes, and prolonged PR interval.
◉ What is a critical nursing intervention for a patient with severe
hyperkalemia? Answer: Assess cardiac rhythm and escalate care
immediately.
, ◉ What is the importance of monitoring electrolytes in cardiovascular
patients? Answer: They are essential for cardiac electrical conduction
and muscle contraction.
◉ What should be done if a patient reports shortness of breath and has
an elevated BNP? Answer: Suspect heart failure with pulmonary
congestion.
◉ What nursing actions should be taken if acute coronary syndrome is
suspected? Answer: Assess chest pain, obtain vital signs, assess oxygen
saturation, and obtain a 12-lead ECG.
◉ What is the significance of daily weight monitoring in heart failure
patients? Answer: It helps to monitor fluid retention effectively.
◉ What is the nursing implication for administering potassium? Answer:
Never administer potassium by IV push; it must be diluted and infused
according to policy.
◉ What should be the nurse's priority if a patient taking spironolactone
has a potassium level of 6.2 mEq/L? Answer: Promptly assess for
cardiac manifestations and obtain cardiac monitoring.
◉ What is the priority action for a patient taking spironolactone with a
potassium level of 6.2 mEq/L? Answer: Promptly assess for cardiac
