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 A
Explanation
Choice A rationale
A WBC count of 2300/mm³ is significantly lower than the normal range (4500-11000/mm³) and indicates leukopenia, which increases the risk of infection. This finding should be reported to the provider.
Choice B rationale
A platelet count of 155,000/mm³ is within the lower end of the normal range (150,000- 450,000/mm³) and does not require immediate reporting.
Choice C rationale
An RBC count of 5 million/mm³ is within the normal range for females (4.2-5.4 million/mm³) and does not require immediate reporting.
Choice D rationale
A hemoglobin level of 12 g/dL is within the normal range for females (12-16 g/dL) and does not require immediate reporting.
Correct Answer is D
Explanation
Choice A rationale
While chest pain can occur after pacemaker insertion, it is not the primary concern immediately following the procedure. The nurse should monitor for more critical complications such as arrhythmias, which can indicate pacemaker malfunction or lead displacement.
Choice B rationale
Infection is a potential complication after pacemaker insertion, but it typically develops over a longer period. Immediate monitoring should focus on acute complications such as arrhythmias.
Choice C rationale
Bleeding is a concern after any surgical procedure, including pacemaker insertion. However, the primary immediate concern is monitoring for arrhythmias, which can indicate issues with the pacemaker’s function.
Choice D rationale
Arrhythmias are the primary concern immediately following pacemaker insertion. The nurse should monitor the client for any irregular heart rhythms, which can indicate pacemaker malfunction or lead displacement. Prompt identification and management of arrhythmias are crucial to ensure the pacemaker is functioning correctly.
