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: Checking the client’s motor strength is not the first priority during a seizure. Ensuring the client’s safety and airway patency is more important.
B: Turning the client’s head to the side is the first action. This helps maintain an open airway and prevents aspiration of saliva or vomit.
C: Documenting the time the seizure began is important for medical records but is not the immediate priority during the seizure.
D: Loosening the clothing around the client’s waist can help with comfort but is not the first action to take during a seizure.
Correct Answer is D
Explanation
A: The statement “Benefit may outweigh the risk” is more applicable to Pregnancy Risk Category D or X drugs, where there is evidence of risk but potential benefits may justify use in certain situations.
B: Studies showing fetal risk are associated with Pregnancy Risk Category D or X drugs. Category A drugs have not shown fetal risk in controlled studies.
C: Drugs that are contraindicated in pregnant women fall under Pregnancy Risk Category X, where the risks clearly outweigh any potential benefits.
D: Fetal harm is unlikely for Pregnancy Risk Category A drugs. These drugs have been tested in controlled studies and have not shown any risk to the fetus, making them safe for use during pregnancy.
