A 29-year-old female patient is admitted to the emergency department with two of the systemic inflammatory response syndrome variables: temperature of 101.2 °F and 14,000 per μL white blood cell count. Which intervention from the sepsis resuscitation bundle does the nurse initiate?
Cooling baths
Broad-spectrum antibiotics
Blood transfusion
NPO status
The Correct Answer is B
The patient's symptoms of fever and elevated white blood cell count suggest a potential infection and sepsis. Broad-spectrum antibiotics should be initiated promptly to cover a wide range of possible pathogens until further diagnostic tests and identification of the specific causative agent are obtained. Early administration of appropriate antibiotics is crucial in sepsis management to target the suspected infection and improve patient outcomes.
A. Cooling baths in (option A) is incorrect because: Cooling baths are typically used in the management of hyperthermia or specific conditions like heatstroke. While the patient has an elevated temperature, it is likely due to the systemic inflammatory response rather than solely hyperthermia.
C. Blood transfusion in (option C) is incorrect because Blood transfusion may be required in certain cases of sepsis if there is evidence of significant anemia or active bleeding. However, based on the information provided, there is no immediate indication of a blood transfusion.
D. NPO status in (option D) is incorrect because NPO status (nothing by mouth) is a general precautionary measure used in various situations, such as prior to surgery or to manage gastrointestinal complications. It is not a specific intervention in the sepsis resuscitation bundle.
Therefore, the nurse should initiate the intervention of administering broad-spectrum antibiotics in this scenario.

Correct Answer is A
Explanation
The QTc (corrected QT) interval is a measure of the time it takes for the ventricles to depolarize and repolarize during a cardiac cycle. It is corrected for heart rate (HR) to account for variations in the cardiac cycle length.
The normal range for the QTc interval varies depending on the calculation method used but generally falls within 0.36 to 0.44 seconds. In the given options, the range of 0.33 to 0.47 seconds for the QTc interval is wider than the normal range, suggesting a prolonged QTc interval, which can be indicative of a potential risk for arrhythmias, including ventricular tachycardia and torsades de pointes.
B. QT interval that varies with HR in (option B) is normal because The QT interval alone can vary with heart rate, and this is considered a normal physiological adaptation.
C. QRS interval <0.12 seconds in (option C) is normal because The QRS interval represents the time it takes for ventricular depolarization and is normally less than 0.12 seconds.
D. PR interval 0.12 to 0.24 seconds in (option D) is normal because The PR interval represents the time it takes for atrial depolarization and conduction through the AV node. The normal range is typically 0.12 to 0.20 seconds.
Correct Answer is B
Explanation
Systemic vascular resistance represents the resistance to blood flow in the systemic circulation. It is an important indicator of afterload, which is the force against which the left ventricle must pump to eject blood into the systemic circulation. By monitoring the changes in SVR, the nurse can assess the impact of medications aimed at reducing left ventricular afterload.
A. Pulmonary artery wedge pressure (PAWP) in (option A) is incorrect because: PAWP is a measure of left ventricular preload and reflects the pressure within the left atrium and left ventricle at end-diastole. It is not specifically related to afterload reduction.
C. Pulmonary vascular resistance (PVR) in (option C) is incorrect because: PVR represents the resistance to blood flow in the pulmonary circulation. It is not directly related to left ventricular afterload.
D. Central venous pressure (CVP) in (option D) is incorrect because: CVP reflects the pressure in the right atrium and is an indicator of right-sided cardiac function. It is not specifically related to left ventricular afterload reduction.
Therefore, to assess the effectiveness of medications in reducing left ventricular afterload, the nurse should monitor the systemic vascular resistance (SVR).
