A patient has been diagnosed with septic shock.
What collaborative interventions would be expected? (Select all that apply)

Temperature control for either hypothermia or hyperthermia.

Administration of cardiotonic agents such as dopamine, dobutamine, or norepinephrine.

Administration of a thrombolytic (streptokinase).

Subcutaneous administration of epinephrine (1:1000) 0.5 to 1 ml every 5 to 15 minutes.

Blood cultures from all suspected sources before administration of antibiotics.

Vigorous intravenous fluid resuscitation with 0.9% sodium chloride.

Answer and Explanation

Correct Answer : A,B,E,F

Choice A rationale:

Temperature control for either hypothermia or hyperthermia is crucial in septic shock management. Here's a detailed explanation:

Hypothermia:

Mechanism: Septic shock often causes impaired thermoregulation, leading to hypothermia. It can worsen shock by decreasing cardiac output, impairing coagulation, and promoting vasoconstriction.

Intervention: Active warming measures are essential, including: External warming devices (e.g., blankets, forced air warmers) Intravenous fluids warmed to 39-42°C

Warmed humidified oxygen

Minimizing exposure and covering the patient Hyperthermia:

Mechanism: Sepsis can trigger an excessive inflammatory response, leading to hyperthermia. It can exacerbate tissue injury, increase metabolic demands, and worsen organ dysfunction.

Intervention: Aggressive measures to lower temperature are necessary, including:

Antipyretic medications (e.g., acetaminophen, ibuprofen) External cooling methods (e.g., cooling blankets, ice packs) Sedation if shivering occurs

Choice B rationale:

Administration of cardiotonic agents such as dopamine, dobutamine, or norepinephrine is often required in septic shock to: Improve cardiac output: These agents increase myocardial contractility and heart rate, enhancing blood flow to vital organs.

Maintain blood pressure: They support vasoconstriction, counteracting the widespread vasodilation characteristic of septic shock.

Improve tissue perfusion: By optimizing cardiac output and blood pressure, they help ensure adequate oxygen and nutrient delivery to tissues.

Choice E rationale:

Blood cultures from all suspected sources before administration of antibiotics are essential for guiding appropriate antibiotic therapy.

Early identification of the causative organism: This information is crucial for selecting the most effective antibiotic regimen.

Prevention of antibiotic resistance: Judicious use of antibiotics based on culture results helps prevent the development of antibiotic-resistant bacteria.

Choice F rationale:

Vigorous intravenous fluid resuscitation with 0.9% sodium chloride is a cornerstone of septic shock management.

Replenishing intravascular volume: Septic shock often causes profound intravascular volume depletion due to capillary leak and vasodilation. Fluid resuscitation aims to restore circulating volume and maintain organ perfusion.

Improving hemodynamic stability: By increasing preload and cardiac output, fluids help stabilize blood pressure and support vital organ function.

Correct Answer is B

Explanation

Choice B rationale:

Stridor is a high-pitched, whistling sound that is heard during inspiration. It is a sign of upper airway obstruction, indicating a potentially life-threatening complication that requires immediate intervention.

Here's a detailed explanation of why stridor is the most concerning finding and why the other choices are not as indicative of a serious problem:

Stridor:

Mechanism: Stridor occurs when there is narrowing or obstruction of the upper airway, typically at the level of the larynx or trachea. This narrowing can be caused by various factors, including:

Laryngospasm: A sudden constriction of the vocal cords, often triggered by irritation or inflammation. Post-extubation edema: Swelling of the tissues in the airway after removal of the endotracheal tube.

Mucus plugging: Accumulation of thick secretions in the airway, which can partially block airflow.

Vocal cord dysfunction: Impairment of the vocal cords' movement, which can affect their ability to open and close properly.

Significance: Stridor is a serious sign because it indicates that airflow is significantly restricted. If left untreated, upper airway obstruction can lead to hypoxia (low oxygen levels) and respiratory failure.

Nursing intervention: If stridor is present, the nurse should immediately notify the provider and prepare for potential interventions to secure the airway, such as:

Reintubation: Reinserting the endotracheal tube to bypass the obstruction.

Nebulized racemic epinephrine: Medication to reduce swelling in the airway.

Heliox: A mixture of helium and oxygen that can improve airflow through a narrowed airway. Steroids: Medications to reduce inflammation in the airway.

Crackles (Choice A):

Description: Crackles are rattling, crackling sounds heard in the lungs, often during inspiration. They are typically associated with lower airway problems, such as pneumonia or pulmonary edema.

Significance: While crackles can indicate respiratory issues, they are not as immediately concerning as stridor in the context of post-extubation care.

Strong cough (Choice C):

Significance: A strong cough is generally a positive sign after extubation, as it indicates that the patient is able to clear secretions from their airway effectively.

Deep breathing (Choice D):

Significance: Deep breathing is also a positive sign, as it promotes lung expansion and oxygenation.

A. Request NPO status for the client. B. Elevate the head of the bed to high Fowler’s. C. Measure the client’s temperature. D. Check the client’s respiratory rate and lung sounds.

Correct Answer is D

Explanation

NPO status (nothing by mouth) is not a relevant intervention in this situation. It would be indicated for a patient with gastrointestinal issues or prior to a procedure, but it does not address the potential consequences of rapid fluid administration.

Restricting oral intake would not reverse or mitigate the effects of fluid overload that may have already occurred.

It's important to prioritize assessment of the patient's respiratory status, as fluid overload can lead to pulmonary edema, a serious complication.

Rationale for Choice B:

Elevating the head of the bed to high Fowler's position can be helpful in easing breathing for patients with respiratory distress, but it's not the most immediate priority in this case.

Assessing the patient's respiratory status directly through respiratory rate and lung sounds will provide more comprehensive information about potential fluid overload and guide further interventions.

Rationale for Choice C:

Measuring the client's temperature is not directly relevant to the concern of rapid fluid administration.

While fever could be a sign of infection, which might warrant fluid administration, it's not the primary concern in this scenario.

The priority is to assess for potential fluid overload, which could manifest as respiratory distress. Rationale for Choice D:

Checking the client's respiratory rate and lung sounds is the most appropriate action for the nurse to take in this situation.

Rapid infusion of 900 mL of fluid within a short period could lead to fluid overload, which can manifest as: Increased respiratory rate

Crackles in the lungs Shortness of breath Hypoxia

Early identification of these signs is crucial for prompt intervention and prevention of serious complications.
