The cardiac ICU nurse is assessing a patient who is in cardiogenic shock. Which hemodynamic manifestations and/or signs and symptoms do the nurse expect? Select all that apply.

Narrowed pulse pressure.

Tachycardia.

Elevated SBP.

Pulmonary congestion.

Pulmonary artery wedge pressure

Answer and Explanation

Correct Answer : A,B,D,E

A. Narrowed pulse pressure: In cardiogenic shock, the cardiac output is compromised, resulting in reduced stroke volume and subsequent narrowed pulse pressure. The pulse pressure is the difference between systolic and diastolic blood pressure.
B. Tachycardia: Tachycardia is a compensatory response in cardiogenic shock, as the body attempts to increase cardiac output to maintain tissue perfusion despite decreased stroke volume. Increased heart rate is a common finding in this condition.
D. Pulmonary congestion: Cardiogenic shock is often associated with impaired left ventricular function, leading to an inadequate pump mechanism. This can result in fluid accumulation and congestion in the pulmonary circulation, leading to pulmonary edema and congestion. Patients may experience symptoms such as dyspnea, crackles on lung auscultation, and increased work of breathing.
E. Elevated pulmonary artery wedge pressure (PAWP): PAWP is a measurement obtained during invasive hemodynamic monitoring. In cardiogenic shock, the impaired left ventricular function leads to increased left atrial pressure, which is reflected by an elevated PAWP. Elevated PAWP indicates increased fluid volume and congestion in the left side of the heart.
C. Elevated SBP in (option C) is incorrect because Elevated systolic blood pressure (SBP) is not a typical finding in cardiogenic shock. Instead, hypotension or decreased blood pressure is commonly observed due to reduced cardiac output.

Correct Answer is C

Explanation

The sepsis resuscitation bundle typically includes the administration of intravenous fluids to restore adequate perfusion and address hypovolemia. The initial fluid of choice is often the crystalloid solution, such as Lactated Ringers (LR), and the recommended initial fluid bolus is 30 ml/kg. This intervention aims to optimize intravascular volume and improve tissue perfusion.

A. Cooling baths in (option A) is incorrect because they may be used in the management of hyperthermia or fever, but they are not specific interventions in the sepsis resuscitation bundle.

B. Blood transfusion in (option B) is incorrect it may be necessary in certain cases of sepsis, such as severe anemia or hypovolemia, but it is not a routine intervention in the sepsis resuscitation bundle based solely on the provided information.

D. NPO status (nothing by mouth) in (option D) is incorrect because it is not a specific intervention in the sepsis resuscitation bundle. It may be indicated in certain cases, such as when surgery is required or if there is a risk of aspiration, but it does not directly address the sepsis-related variables mentioned.

It is important to note that the specific management of sepsis may vary based on the patient's individual condition, clinical presentation, and healthcare provider's orders.

A. The mean arterial pressure (MAP) is 50 mm Hg. B. Cardiac Out (CO) is 4 L/min C. Stroke volume 70 ml/beat D. The heart rate is 80 bpm.

Correct Answer is A

Explanation

Mean arterial pressure (MAP) is a measure of the average pressure within the arteries during one cardiac cycle. It represents the perfusion pressure that drives blood flow to organs and tissues. In the context of shock, a MAP of 50 mm Hg is considered low and indicates inadequate tissue perfusion.
To improve tissue perfusion and restore blood pressure, the nurse would anticipate administering large volumes of intravenous fluids, such as Lactated Ringers (LR). Fluid resuscitation aims to increase intravascular volume and improve cardiac output, ultimately leading to improved tissue perfusion.
B. Cardiac Output (CO) is 4 L/min in (option A) is incorrect because Cardiac output represents the volume of blood pumped by the heart per minute. While a low cardiac output may require intervention, it does not specifically indicate the need for large volumes of fluid administration.
C. Stroke volume is 70 ml/beat in (option C) is incorrect because Stroke volume refers to the volume of blood ejected by the heart with each contraction. While stroke volume can be an important determinant of cardiac output, it alone does not indicate the need for large fluid volumes.
D. The heart rate is 80 bpm in (option D) is incorrect because: Heart rate is the number of heartbeats per minute. While the heart rate can impact cardiac output, it does not provide direct information about fluid resuscitation needs.

A 30-year-old female patient is admitted to the emergency department with two systemic inflammatory response syndrome variables: temperature of 100.2°F (35°C) and high blood sugar. Which intervention from the sepsis resuscitation bundle does the nurse initiate?

Explanation

The medical-surgical nurse is caring for a 55-year-old female patient after surgery. The patient's respiratory rate has increased from 12 to 22 breaths/min, and the pulse rate has increased from 86 to 110 beats/min since the patient was last assessed 4 hours ago. What action by the nurse is best?
