A nurse is caring for a 73-year-old client in the emergency department (ED)

Exhibits
It has been identified that the client is in sepsis. Select the 4 actions that the nurse should complete in the first hour to manage sepsis and prevent further complications?

Insert a nasogastric (NG) tube.

Type and cross-match for 2 units of packed RBCs.

Administer broad-spectrum antibiotics.

Measure lactate level.

Rapidly administer 30 ml/kg of normal saline.

Obtain blood cultures.

Obtain a urine specimen.

Obtain a wound culture.

Answer and Explanation

Correct Answer : C,D,E,F

A. Administering antibiotics helps target the suspected infection and prevent its spread. Broad-spectrum antibiotics are typically initiated until the specific pathogen is identified through cultures. This action should be completed as soon as possible within the first hour.

D. Lactate measurement is important in assessing tissue perfusion and the severity of sepsis. Elevated lactate levels indicate tissue hypoperfusion and can help identify patients at higher risk of mortality. Monitoring lactate levels guides resuscitation efforts and helps in assessing the response to treatment.

E. Fluid resuscitation is a cornerstone in the management of sepsis. Administering a large volume of intravenous fluids helps restore intravascular volume, improve tissue perfusion, and prevent further organ dysfunction. The recommended initial fluid bolus is 30 ml/kg of crystalloid solution, such as normal saline, administered rapidly within the first few hours of recognition of sepsis.

F. Blood cultures help identify the causative organism(s) responsible for the sepsis. This information is crucial for guiding antibiotic therapy, especially in cases of severe sepsis or septic shock. Blood cultures should be obtained before initiating antibiotic therapy to maximize their sensitivity and specificity.

B. Type and cross-match for packed red blood cells (PRBCs) are indicated in situations where blood transfusion may be required, such as severe anemia or active bleeding. While sepsis can lead to various complications, such as disseminated intravascular coagulation (DIC), the priority in the first hour is resuscitation and antibiotic administration.

G. Obtaining a urine specimen may be indicated to assess for urinary tract infection (UTI), which can be a potential source of sepsis. However, in the initial management of sepsis, obtaining blood cultures (option F) takes precedence as blood cultures provide more critical information for guiding antibiotic therapy.

H. Obtaining a wound culture may help identify the specific pathogens present in the wound and guide antibiotic therapy if the wound is suspected to be the source of sepsis. However, in the first hour of managing sepsis, the priority is to initiate broad-spectrum antibiotics and obtain blood cultures, as these interventions are more urgent in preventing further complications from sepsis.

Correct Answer is A

Explanation

A. Nitroglycerin is a vasodilator commonly used to reduce preload and afterload in critical care settings. By dilating blood vessels, nitroglycerin decreases systemic vascular resistance (afterload), which reduces the workload on the heart and improves cardiac output. It is often used to manage conditions such as acute heart failure, hypertensive emergencies, and acute coronary syndromes.

B. Metoprolol is a beta-blocker that primarily acts to reduce heart rate and myocardial contractility. While it can indirectly reduce afterload by lowering blood pressure, its primary mechanism of action is not targeted at afterload reduction. Metoprolol is commonly used in critical care for various indications, including hypertension, myocardial infarction, and heart failure, but it is not primarily used for afterload reduction.

C. Furosemide is a loop diuretic commonly used to manage volume overload and reduce preload in critical care settings. By promoting diuresis, furosemide decreases circulating blood volume, venous return, and preload, which indirectly reduces afterload. However, its primary mechanism of action is not targeted at afterload reduction but rather at reducing volume overload.

D. Epinephrine is a potent sympathomimetic agent that acts on alpha and beta-adrenergic receptors. While it can increase systemic vascular resistance (afterload) at higher doses due to its alpha-adrenergic effects, it is not commonly used for afterload reduction in critical care settings. Epinephrine is primarily used as a vasopressor to increase blood pressure and cardiac output in patients with shock or cardiac arrest.

A. Pulmonary artery wedge pressure (PAWP) is low. B. Systemic vascular resistance (SVR) is elevated. C. Mean arterial pressure (MAP) is 56 mm Hg D. Heart rate is slow at 58 beats/min.

Correct Answer is C

Explanation

C. Mean arterial pressure (MAP) reflects the average pressure in the arteries during one cardiac cycle and is an important indicator of tissue perfusion. A MAP of 56 mm Hg is below the normal range (typically >60 mm Hg) and may indicate inadequate tissue perfusion. While norepinephrine is commonly used to increase blood pressure and improve tissue perfusion in hypotensive patients, a MAP of 56 mm Hg suggests that the current infusion rate may not be sufficient to maintain adequate perfusion, and adjusting the infusion rate may be warranted.

A. Norepinephrine is a vasopressor medication primarily used to increase blood pressure in patients with hypotension or shock. A low pulmonary artery wedge pressure (PAWP) suggests decreased preload, which may indicate hypovolemia or inadequate fluid resuscitation. In this case, adjusting the norepinephrine infusion rate may not be necessary, but rather addressing the underlying cause of hypovolemia or inadequate preload.

B. Systemic vascular resistance (SVR) represents the resistance the heart must overcome to pump blood into the systemic circulation. An elevated SVR may suggest vasoconstriction, which could be a desired effect of norepinephrine infusion to increase blood pressure. Therefore, an elevated SVR may not necessarily indicate a need to adjust the norepinephrine infusion rate, as it may reflect the medication's intended action.

D. Norepinephrine primarily acts on alpha-adrenergic receptors to increase blood pressure by inducing vasoconstriction. While it may cause reflex bradycardia due to increased systemic vascular resistance, a heart rate of 58 beats/min may be within an acceptable range depending on the patient's clinical condition and baseline heart rate. Therefore, a slow heart rate alone may not necessarily indicate a need to adjust the norepinephrine infusion rate unless it is associated with signs of inadequate tissue perfusion or other concerning symptoms.
