A nurse is providing postoperative care to a client who lost 800 mL of blood during surgery. The client’s blood pressure has been steadily decreasing over the past 2 hours.
Which of the following categories of shock should the nurse recognize is occurring?
Hypovolemic shock.
Septic shock.
Neurogenic shock.
Obstructive shock.
The Correct Answer is C
Choice A rationale
Hypovolemic shock occurs due to a significant decrease in circulating blood volume, leading to inadequate tissue perfusion. Blood loss, such as the 800 mL lost during surgery, is a common cause of hypovolemic shock. The steadily decreasing blood pressure is consistent with this type of shock.
Choice B rationale
Septic shock results from a systemic inflammatory response to infection, leading to vasodilation and maldistribution of blood flow. There is no indication of infection in this scenario.
Choice C rationale
Neurogenic shock results from a loss of sympathetic tone, leading to vasodilation and relative hypovolemia. It is often associated with spinal cord or severe head injury, which is not indicated in this scenario.
Choice D rationale
Obstructive shock occurs when there is an obstruction to blood flow within the cardiovascular system, such as a pulmonary embolism or cardiac tamponade. There is no evidence of such an obstruction in this scenario.

Correct Answer is B
Explanation
Choice A rationale
Doubling the dose of warfarin if a dose is missed is incorrect because it can lead to an increased risk of bleeding. Warfarin is an anticoagulant, and maintaining a consistent blood level is crucial to avoid complications. Doubling the dose can cause the blood to become too thin, leading to severe bleeding events.
Choice B rationale
Using an electric razor while on warfarin is correct because it helps prevent cuts and bleeding. Warfarin increases the risk of bleeding, and using an electric razor reduces the chance of nicks and cuts that can occur with a traditional razor.
Choice C rationale
Increasing fiber intake to reduce constipation is incorrect because warfarin does not typically cause constipation. Fiber intake is generally recommended for overall digestive health, but it is not specifically related to warfarin use.
Choice D rationale
Mild nosebleeds are not common during initial treatment with warfarin. Nosebleeds can indicate that the blood is too thin, which is a sign of over-anticoagulation and requires medical attention.
Correct Answer is B
Explanation
Choice A rationale
Fever. This statement is incorrect. While fever can occur in clients with ITP due to infections, it is not a specific manifestation of the condition. ITP primarily affects platelet counts and bleeding tendencies.
Choice B rationale
Ecchymosis. This statement is correct. Ecchymosis, or bruising, is a hallmark manifestation of ITP due to low platelet counts and increased bleeding tendencies. Clients with ITP are prone to bruising and bleeding even with minor trauma.
Choice C rationale
Fatigue. This statement is incorrect. While fatigue can occur in clients with ITP due to anemia or chronic illness, it is not a specific manifestation of the condition. ITP primarily affects platelet counts and bleeding tendencies.
Choice D rationale
Elevated WBC. This statement is incorrect. Elevated white blood cell counts are not typically associated with ITP, which primarily affects platelet counts. An elevated WBC may indicate infection or inflammation but is not specific to ITP10111213.
