Which of the following signs are commonly associated with fluid volume deficit (hypovolemia)? (Select All that Apply.)
Orthostatic hypotension
Bradycardia
Decreased skin turgor
Weight gain
Pulmonary edema
Correct Answer : A,C
A. Orthostatic hypotension is a common sign of hypovolemia, as the lack of fluid volume can lead to a drop in blood pressure when changing positions.
B. Bradycardia is not typically associated with fluid volume deficit; tachycardia is more common as the body tries to compensate for low blood volume.
C. Decreased skin turgor is a classic sign of dehydration and fluid volume deficit, indicating reduced skin elasticity.
D. Weight gain is associated with fluid volume overload, not deficit.
E. Pulmonary edema is related to fluid volume overload or congestive heart failure, not hypovolemia.

Correct Answer is C
Explanation
A. DIC is characterized by a low platelet count due to the consumption of platelets in the coagulation process, not an elevated count.
B. While heparin may be used in the management of DIC in some cases, it is not a lifelong treatment nor a cure for the condition, as DIC results from an underlying condition rather than being a standalone disease.
C. DIC involves the overactivation of the coagulation cascade, leading to the formation of fibrin clots and subsequent consumption of clotting factors and platelets, thus making this statement accurate.
D. DIC is not a genetic disorder but rather a complication often associated with severe infections, trauma, or other conditions, and it is not primarily due to vitamin K deficiency.
Correct Answer is A
Explanation
A. Stridor is a high-pitched sound indicating upper airway obstruction and is a critical sign of anaphylaxis requiring immediate intervention to secure the airway.
B. Hypotension is a serious condition that occurs during anaphylaxis, but the priority is to address the airway obstruction first.
C. Urticaria (hives) is a common symptom of an allergic reaction but is not life-threatening and can be addressed after more severe symptoms.
D. Vomiting may occur during anaphylaxis but is not the most urgent finding when airway compromise is present.
