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 B
Explanation
A: Applying petroleum jelly to the client’s lips after oral care can help prevent dryness and cracking, but it is not the primary action to ensure safety during oral care.
B: Turning the client on his side before starting oral care is the correct action. This position helps prevent aspiration of fluids and secretions during the procedure, ensuring the client’s safety.
C: Using the thumb and index finger to keep the client’s mouth open is not safe or effective. A mouth prop or padded tongue blade should be used instead.
D: Using a stiff toothbrush can cause damage to the gums and oral tissues. A soft-bristled toothbrush is recommended for gentle and effective cleaning.
Correct Answer is C
Explanation
A: A simple face mask provides a moderate concentration of oxygen but does not have a one-way valve to deliver the highest concentration of oxygen.
B: A Venturi mask delivers a precise concentration of oxygen but is not designed to provide the highest concentration of oxygen with a one-way valve.
C: A non-rebreather mask is the correct choice. It has a one-way valve that prevents exhaled air from re-entering the bag, allowing the delivery of the highest concentration of oxygen to the client.
D: A partial rebreather mask provides a high concentration of oxygen but does not have a one-way valve, making it less effective than a non-rebreather mask for delivering the highest oxygen concentration.
