The findings from an assessment of a 70-year-old patient with swelling in his
ankles
include jugular venous pulsations 5 cm above the sternal angle when the head of
his bed is elevated 45 degrees. The nurse knows that this finding indicates:
a. Decreased fluid volume.
b. .. Increased cardiac output.
c. Narrowing of jugular veins.
d. Elevated pressure related to heart failure.
d. Elevated pressure related to heart failure.
,When assessing a newborn infant who is 5 minutes old, the nurse knows which of
these statements to be true?
a. The left ventricle is larger and weighs more than the right ventricle.
b. The circulation of a newborn is identical to that of an adult.
c. Blood can flow into the left side of the heart through an opening in the atrial
septum.
d. .. The foramen ovale closes just minutes before birth, and the ductus
arteriosus closes immediately after.
c. Blood can flow into the left side of the heart through an opening in the atrial
septum.
A 25-year-old woman in her fifth month of pregnancy has a blood pressure of
100/70 mm Hg. In reviewing her previous examination, the nurse notes that her
blood pressure in her second month was 124/80 mm Hg. In evaluating this
change, what does the nurse know to be true?
a. This decline in blood pressure is the result of peripheral vasodilatation
and is an expected change.
b. Because of increased cardiac output, the blood pressure should be higher at
this time.
c. This change in blood pressure is not an expected finding because it means a
decrease in cardiac output.
d. This decline in blood pressure means a decrease in circulating blood volume,
which is dangerous for the fetus.
a. This decline in blood pressure is the result of peripheral vasodilatation
and is an expected change.
, In assessing a 70-year-old man, the nurse finds the following: blood pressure
140/100 mm Hg; heart rate 104 beats per minute and slightly irregular; and
the split S2 heart sound. Which of these findings can be explained by
expected hemodynamic changes related to age?
a. Increase in resting heart rate
b. Increase in systolic blood pressure
c. Decrease in diastolic blood pressure
d. .. Increase in diastolic blood pressure
b. Increase in systolic blood pressure
During an inspection of the precordium of an adult patient, the nurse notices
the chest moving in a forceful manner along the sternal border. This finding
most likely suggests a(n):
a. Normal heart.
b. Systolic murmur.
c. .. Enlargement of the left ventricle.
