Correct Answer is C
Explanation
A) Incorrect. Atrial contraction contributes to ventricular filling but is not typically the primary site of impairment in heart failure leading to pulmonary edema.
B) Incorrect. Ventricular relaxation (diastole) is necessary for ventricular filling, but the impaired contraction during systole is a more common issue in heart failure.
C) Correct. Impaired ventricular contraction (systole) in heart failure results in reduced forward flow of blood and leads to fluid backup in the lungs, contributing to pulmonary edema.
D) Incorrect. Electrical conduction in the heart may affect heart rhythm but is not directly related to the development of pulmonary edema.
Correct Answer is A
Explanation
A) Correct. Skin temperature and color can provide important clues about tissue perfusion and oxygenation, which are critical in pulmonary edema.
B) Incorrect. While urinary output is important, it is not the primary focus when monitoring respiratory status in pulmonary edema.
C) Incorrect. Bowel sounds are unrelated to pulmonary edema and should not be the priority assessment.
D) Incorrect. Peripheral edema may be a sign of fluid retention, but skin color and temperature are more directly related to respiratory status.
