CHAPTER 25 NUR 257 QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT!!!
What term describes the cardiac phase in which the heart chambers contract and
pump blood into systemic and pulmonary circulation? ✔✔ Systole
Where can a nurse most accurately locate and palpate a patient's point of maximal
impulse (PMI) on the chest wall? ✔✔ At the fifth intercostal space along the left
midclavicular line.
How is pulse pressure calculated for a patient whose blood pressure reading is
122/76 mm Hg? ✔✔ The pulse pressure is 46 mm Hg, calculated by
subtracting the diastolic pressure from the systolic pressure (122 - 76 = 46).
What is the clinical significance of an elevated serum troponin I level in a patient
admitted with chest pain and unstable angina? ✔✔ An elevated troponin I level
serves as a highly specific biomarker indicating active myocardial cellular
damage or injury.
The nurse is conducting patient teaching about cholesterol levels. When discussing
the patients elevated LDL and lowered HDL levels, the patient shows an
understanding of the significance of these levels by stating what?
"Increased LDL and decreased HDL increase my risk of coronary artery disease."
The physician has placed a central venous pressure (CVP) monitoring line in an
acutely ill patient so right ventricular function and venous blood return can be
closely monitored. The results show decreased CVP. What does this indicate?
, Possible hypovolemia
While auscultating a patients heart sounds, the nurse hears an extra heart sound
immediately after the second heart sound (S2). An audible S3 would be considered
an expected finding in what patient?
A 20-year-old patient
The physical therapist notifies the nurse that a patient with coronary artery disease
(CAD) experiences a much greater-than-average increase in heart rate during
physical therapy. The nurse recognizes that an increase in heart rate in a patient
with CAD may result in what?
myocardial ischemia
The nurse is caring for a patient who has a history of heart disease. What factor
should the nurse identify as possibly contributing to a decrease in cardiac output?
A heart rate of 54 bpm
The nurse is caring for an 82-year-old patient. The nurse knows that changes in
cardiac structure and function occur in older adults. What is a normal change
expected in the aging heart of an older adult?
