Correct Answer is ["C","D"]

Explanation

A. Increased temperature: Fluid overload typically doesn't cause an increased temperature. Infections or other inflammatory processes are more likely causes of elevated body temperature.

B. Increased hematocrit: Fluid overload usually results in dilution of blood components, leading to a decreased hematocrit (lower concentration of red blood cells in the blood). An increased hematocrit is not a typical finding in fluid overload.

C. Blood pressure 180/100: Elevated blood pressure can be associated with fluid overload, especially if the overload is chronic. This is a correct assessment finding that requires intervention and monitoring.

D. Respiratory rate 32: An increased respiratory rate can be a sign of respiratory distress, which may occur in severe cases of fluid overload, especially if it leads to pulmonary edema. This is a correct assessment finding that requires intervention and further evaluation.

E. Heart rate 120 bpm: An increased heart rate can be a compensatory mechanism in response to fluid overload, especially if the heart is trying to maintain cardiac output. However, this heart rate alone is not specific enough to confirm fluid overload. Other signs and symptoms, such as edema, increased blood pressure, and respiratory distress, are more indicative of fluid overload.

A. Indicates the beginning of diastole B. Coincides with the carotid artery pulse C. is louder than an S1 D. Is caused by the closure of the semilunar valves

Correct Answer is D

Explanation

A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.

B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.

C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.

D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.
