The emergency department nurse evaluates that fluid resuscitation for a 70 kg patient in shock is effective by finding which one of the following?
The patient's mean arterial pressure (MAP) is 50 mm Hg.
The patient's GCS score is 9.
The patient's urine output has been 35 ml over the last hour.
The patient's hemoglobin is within normal limits.
The Correct Answer is C
Urine output is an essential indicator of renal perfusion and overall fluid status. In a patient in shock, maintaining an adequate urine output is a crucial goal of fluid resuscitation. A urine output of 0.5 to 1 mL/kg/hour is generally considered adequate in adults. The given value of 35 ml over the last hour suggests that the patient is producing urine, which indicates that fluid resuscitation is effective in restoring perfusion to the kidneys.
A. The patient's mean arterial pressure (MAP) is 50 mm Hg in (option A) is incorrect because While mean arterial pressure is an important hemodynamic parameter, a single value alone may not provide a comprehensive assessment of the patient's response to fluid resuscitation.
B. The patient's GCS score is 9 in (option B) is incorrect because The Glasgow Coma Scale (GCS) assesses the level of consciousness and neurological function but does not directly reflect fluid resuscitation effectiveness.
D. The patient's hemoglobin is within normal limits: (option D) is incorrect because Haemoglobin levels are important for assessing oxygen-carrying capacity but do not directly indicate the effectiveness of fluid resuscitation.
Therefore, the nurse can evaluate that fluid resuscitation for a 70 kg patient in shock is effective by observing a urine output of 35 ml over the last hour.

Correct Answer is C
Explanation
In a patient receiving mechanical ventilation, a high respiratory rate can indicate increased work of breathing and potential airway obstruction. COPD patients, in particular, may have excessive mucus production and airway inflammation, leading to mucus plugging and compromised airway clearance. Suctioning may be necessary to remove excessive secretions and maintain a patent airway.
A. The pulse oximeter shows a SpO2 of 90% in (option A) is incorrect because While a SpO2 of 90% is suboptimal and may require intervention, it does not specifically indicate the need for suctioning. Other interventions, such as adjusting oxygen delivery or ventilation settings, may be more appropriate.
B. The patient has not been suctioned for the last 6 hours in (option B) is incorrect because The duration since the last suctioning episode alone does not necessarily indicate the need for suctioning. The need for suctioning should be based on the patient's clinical presentation, such as signs of airway obstruction or excessive secretions.
D. The lungs have occasional audible expiratory wheezes in (option D) which is incorrect because Occasional audible expiratory wheezes may be common in patients with COPD and may not specifically indicate the need for suctioning. Wheezing is more commonly associated with narrowing of the airways, and suctioning is typically performed to clear secretions or maintain airway patency.
C. Therefore, in a COPD patient receiving mechanical ventilation, a high respiratory rate (C) is the assessment information that would indicate the need for suctioning to help remove excessive secretions and ensure a patent airway
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.
