The nurse is caring for a patient receiving a continuous norepinephrine (Levophed) IV infusion. Which patient assessment information indicates that the infusion rate may be too high?
Mean arterial pressure is 55 mm Hg.
Systemic vascular resistance (SVR) is elevated.
Pulmonary artery wedge pressure (PAWP) is low.
Heart rate is 58 beats/min.
The Correct Answer is D
Norepinephrine is a potent vasoconstrictor and inotropic agent commonly used to increase blood pressure in cases of hypotension or shock. However, if the infusion rate is too high, it can lead to excessive vasoconstriction and potentially compromise organ perfusion.
A heart rate of 58 beats/min suggests bradycardia, which can be an indication of excessive vasoconstriction caused by a high dose or rate of norepinephrine infusion. Excessive vasoconstriction can reduce cardiac output and worsen tissue perfusion.
A. Mean arterial pressure is 55 mm Hg in (option A) is incorrect because A mean arterial pressure of 55 mm Hg may be within an acceptable range for a patient receiving norepinephrine infusion, depending on the patient's baseline blood pressure and clinical condition.
B. Systemic vascular resistance (SVR) is elevated in (option B) is incorrect because An elevated SVR indicates increased peripheral vascular resistance and can be a desired effect of norepinephrine infusion to improve blood pressure and perfusion.
C. Pulmonary artery wedge pressure (PAWP) is low in (option C) which is incorrect because A low PAWP may indicate decreased left ventricular preload, which can be a desired effect of norepinephrine infusion to reduce fluid overload in certain clinical conditions.
It is important for the nurse to carefully monitor the patient's hemodynamic parameters, including blood pressure, heart rate, and organ perfusion when titrating norepinephrine infusion to ensure optimal dosing and minimize potential adverse effects. If concerns arise regarding the infusion rate, the healthcare provider should be promptly notified for further evaluation and adjustment of the treatment plan.

Correct Answer is A
Explanation
The ABG results show a pH of 7.50, PaCO2 of 29 mmHg, and HCO3 of 23 mEq/L, indicating respiratory alkalosis. In respiratory alkalosis, there is a decrease in PaCO2 (hypocapnia), which can be caused by excessive ventilation.
To address the respiratory alkalosis, the nurse should decrease the respiratory rate. This would help reduce the amount of ventilation provided and allow the patient to retain more carbon dioxide (CO2), thereby increasing the PaCO2 levels and restoring acid-base balance.
B. Leaving the ventilator at the current settings in (option B) is incorrect because it may exacerbate respiratory alkalosis as it would maintain the same level of ventilation.
C. Increasing the tidal volume (VT) in (option C) is incorrect because it would not address the respiratory alkalosis. Tidal volume refers to the volume of air delivered with each breath, while the issue in this case is excessive ventilation leading to hypocapnia.
D. Increasing the FiO2 (fraction of inspired oxygen) in (option D) is incorrect because it is not indicated based on the given ABG results. The oxygenation (PaO2) level is within normal limits (80 mmHg), suggesting adequate oxygenation.
It is important to consult with the healthcare provider or respiratory therapist for further guidance on adjusting the ventilator settings based on the patient's condition and response to therapy.
Correct Answer is B
Explanation
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.
