Which of the following clinical manifestations of Disseminated intravascular coagulation (DIC)?
Decreased hematocrit, increased platelet counts, increased D-dimer
Decreased platelet counts, increased D-dimer, increased prothrombin time
Decreased Antithrombin III, increased platelet counts, increased fibrinogen
Decreased D-dimer, increased platelet counts, Increased hemoglobin
The Correct Answer is B
Disseminated Intravascular Coagulation (DIC) is a condition characterized by widespread activation of the coagulation system, leading to both excessive clot formation and consumption of clotting factors and platelets. This process can result in both bleeding and thrombosis.
The manifestations mentioned in option B are commonly seen in DIC:
Decreased platelet counts: DIC leads to platelet consumption and destruction, resulting in low platelet counts (thrombocytopenia).
Increased D-dimer: D-dimer is a fibrin degradation product, and its levels are increased DIC due to the breakdown of fibrin clots.
Increased prothrombin time (PT): DIC can lead to the depletion of clotting factors, resulting in prolonged prothrombin time, indicating impaired coagulation.
The other options mentioned do not represent the typical clinical manifestations of DIC:
A. Decreased hematocrit, increased platelet counts, and increased D-dimer in (option A) are incorrect because While platelet counts and D-dimer are increased in DIC, decreased hematocrit is not a characteristic finding.
C. Decreased Antithrombin III, increased platelet counts, and increased fibrinogen in (option C) is incorrect because: Decreased Antithrombin III can be seen in DIC, but increased platelet counts and fibrinogen levels are not specific to DIC.
D. Decreased D-dimer, increased platelet counts, and increased hemoglobin in (option D) is incorrect because Decreased D-dimer and increased hemoglobin are not typical findings in DIC, while increased platelet counts can be seen in some cases.

Correct Answer is B
Explanation
Central venous pressure (CVP) is a measurement of the pressure in the central veins, which reflects the blood volume and right-sided cardiac function. High CVP readings may indicate fluid overload or impaired cardiac function, and intervention is necessary to address the underlying cause.
Administering IV diuretic medications can help reduce fluid volume by increasing urine output and promoting fluid elimination. By removing excess fluid, the diuretic medications can help lower the CVP and alleviate the high pressures.
The other options mentioned are not the anticipated actions for addressing high CVP:
A. Increasing the IV fluid infusion rate in (option A) is incorrect because: If the CVP is already indicating high pressures, increasing the IV fluid infusion rate would further contribute to fluid overload and exacerbate the problem. This action would not be appropriate for high CVP readings.
C. Elevating the head of the patient's bed to 45 degrees in (option C) is incorrect because Positioning the patient with the head of the bed elevated is commonly done to prevent complications such as aspiration or improve respiratory function. While it may have other benefits, it does not directly address the high CVP.
D. Documenting the CVP and continuing to monitor in (option D) is incorrect because Documenting the CVP and continuing to monitor is important for ongoing assessment and evaluation. However, in the presence of high CVP readings, intervention is necessary to address the underlying issue rather than solely documenting and monitoring.
Therefore, when a patient's CVP monitor indicates high pressures following surgery, the nurse would anticipate administering IV diuretic medications to help reduce fluid volume and lower the CVP.
Correct Answer is D
Explanation
In septic shock, prompt administration of antibiotics is crucial in order to target the underlying infection and prevent further progression of the septic process. Antibiotics help to eradicate the causative organisms and reduce the bacterial load, which can help improve patient outcomes.
While all the options mentioned are important interventions in the management of septic shock, initiating antibiotic therapy is considered a priority in order to address the underlying infection and prevent sepsis-related complications.
A. Giving a 2000 mL normal saline bolus in (option A) is incorrect because: Fluid resuscitation is important in septic shock to restore intravascular volume, but antibiotic therapy takes precedence as it directly targets the underlying infection.
B. Starting an insulin drip to maintain blood glucose at 110 to 150 mg/dL in (option B) is incorrect because Glycemic control is important in septic shock, but it is not the first priority compared to addressing the infection.
C. Giving acetaminophen (Tylenol) 650 mg rectally in (option C) is incorrect because Antipyretic medications can help reduce fever, but they do not address the underlying infection or stabilize the patient's condition.
E. Starting norepinephrine (Levophed) to keep systolic blood pressure >90 mm Hg in (option E) is incorrect because: Vasopressor support may be necessary in septic shock to maintain adequate blood pressure, but initiating antibiotics takes priority in order to address the underlying infection.
Therefore, in a patient with septic shock presenting with the given signs and symptoms, the nurse should first implement the intervention of giving the prescribed antibiotics to target the underlying infection.
