A nurse is caring for a client who sustained blood loss. Which is a manifestation of hypovolemia?
Dyspnea
Increased blood pressure
Weak pulse
Decreased heart rate
The Correct Answer is C
A: Dyspnea, or difficulty breathing, can occur in various conditions but is not a primary manifestation of hypovolemia. Hypovolemia primarily affects the cardiovascular system due to reduced blood volume.
B: Increased blood pressure is not a typical manifestation of hypovolemia. In fact, hypovolemia usually leads to decreased blood pressure due to the reduced volume of circulating blood.
C: A weak pulse is a common manifestation of hypovolemia. The reduced blood volume leads to decreased cardiac output, resulting in a weak and thready pulse.
D: Decreased heart rate is not typical in hypovolemia. The body usually compensates for low blood volume by increasing the heart rate (tachycardia) to maintain adequate circulation.

Correct Answer is A
Explanation
A: Cleaning hearing aids with alcohol wipes is not recommended as it can damage the devices. The client should use a soft, dry cloth or a cleaning tool designed for hearing aids.
B: Expecting the hearing aids to whistle when cupping a hand over them is normal. This feedback occurs due to the sound being reflected back into the microphone.
C: Not using hairspray while wearing hearing aids is correct. Hairspray can clog the microphone and other components of the hearing aids.
D: Changing the batteries once a week is a reasonable practice, depending on the usage and type of hearing aids. This statement does not indicate a need for further instruction.
