After repositioning a patient, an arterial-line MAP reads lower and the transducer is now above the patient’s heart. This position can make the pressure reading falsely low. Is this statement true or false?

False

A patient develops intense systemic vasoconstriction, and both stroke volume and cardiac output fall. Which change in cardiac loading can help explain the reduced output?

A
Reduced afterload explains the fall in stroke volume, despite intense systemic vasoconstriction.
B
Increased afterload can make ejection more difficult, reducing stroke volume and cardiac output.
C
Increased contractility is the loading change that directly explains the fall in stroke volume.
D
The rise in arterial pressure guarantees that cardiac output will increase.

Which approach can help assess fluid responsiveness by testing whether flow increases with a reversible change in venous return?

A
Use the initial CVP as the sole basis for deciding whether to give fluid.
B
Give a fluid bolus and infer responsiveness from the change in CVP alone.
C
When appropriate, measure stroke volume or cardiac output during a passive leg raise.
D
Use a single blood-pressure reading to determine whether cardiac output will respond to fluid.

A patient’s blood pressure is 86/50 mm Hg. Using $\mathrm{MAP} \approx \mathrm{DBP} + \frac{1}{3}(\mathrm{SBP} - \mathrm{DBP})$ , which estimate and interpretation are most appropriate when the patient is becoming less alert and has cool extremities?

A
About 50 mm Hg; the clinical signs are not concerning if diastolic pressure is stable.
B
About 62 mm Hg; the estimate and worsening clinical signs are concerning and warrant prompt reassessment and escalation.
C
About 68 mm Hg; the signs indicate that perfusion is adequate.
D
About 86 mm Hg; systolic pressure is the appropriate estimate of MAP.

Use $\mathrm{SVR} \approx 80 \times (\mathrm{MAP} - \mathrm{CVP}) \div \mathrm{CO}$ . If MAP is 70 mm Hg, CVP is 10 mm Hg, and cardiac output is 8 L/min, calculate SVR in dyn·s/cm⁵.

A patient’s blood pressure has changed little, but the clinical picture is changing. Which findings should raise concern for deterioration and impaired perfusion? Select all that apply.

A
Rising heart rate
B
Falling urine output
C
Unchanged blood pressure by itself as proof that perfusion is adequate
D
New confusion and cool, clammy skin

After a patient is repositioned, the arterial-line MAP reads lower than the cuff measurement, but the patient appears unchanged and the transducer is above heart level. Which steps should be taken to check the measurement before interpreting the discrepancy? Select all that apply.

A
Re-level the transducer to the appropriate reference point.
B
Verify that the system is zeroed as required.
C
Inspect the arterial waveform and tubing, and compare with a properly obtained cuff measurement.
D
Treat the lower arterial-line reading as physiologic deterioration without checking the setup.

A patient with suspected infection has a CVP of 3 mm Hg. After a fluid bolus, CVP rises to 11 mm Hg, measured cardiac output is unchanged, and new crackles are heard. Explain what these findings suggest about giving more fluid based only on CVP, and describe the appropriate response.

A patient has low arterial pressure. Which statement best explains why this finding alone does not establish that cardiac output is low?

A
Low arterial pressure always means cardiac output is low.
B
Arterial pressure is influenced by both cardiac output and vascular resistance, so low pressure alone does not establish low cardiac output.
C
High cardiac output always produces high arterial pressure, regardless of vascular resistance.
D
Blood pressure directly measures tissue perfusion and is not affected by vascular resistance.

True or false

The common estimate $\mathrm{MAP} \approx \mathrm{DBP} + \frac{1}{3}(\mathrm{PP})$ is an approximation and may be less reliable when heart rate is high or rhythm is irregular.

True

False

A patient develops intense systemic vasoconstriction. Arterial pressure rises while stroke volume and cardiac output fall. Which change in cardiac loading best helps explain the reduced output?

A
Reduced preload, which directly increases the load needed for ejection
B
Increased afterload, which can reduce stroke volume and cardiac output
C
Reduced afterload, which prevents ventricular ejection
D
Increased contractility, which necessarily lowers stroke volume

After repositioning, an arterial-line MAP reads lower than the cuff measurement, but the patient appears unchanged. The transducer is above the patient’s heart. What should you do first to check the discrepant reading?

A
Increase the displayed pressure to match the cuff without checking the setup
B
Treat the lower reading as definite physiologic deterioration
C
Re-level the transducer, then verify the system and waveform
D
Ignore the cuff measurement and assess only the displayed MAP

When appropriate, which approach can help assess whether a patient’s flow increases with a reversible change in venous return?

A
Measure stroke volume or cardiac output during a passive leg raise
B
Use the baseline CVP alone to decide whether more fluid will increase output
C
Repeat the static CVP measurement and assume a rise means output increased
D
Use blood pressure alone as proof of fluid responsiveness

A patient with suspected infection has a CVP of 3 mm Hg. After a fluid bolus, CVP rises to 11 mm Hg, measured cardiac output is unchanged, and new crackles are heard. Which interpretation is best?

A
The rise in CVP proves cardiac output improved, so give more fluid
B
The initial CVP of 3 mm Hg establishes that the patient needs additional fluid
C
The new crackles confirm that cardiac output has increased
D
The findings do not show improved cardiac output and raise concern for congestion; reassess and escalate
