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.
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 A rationale:
Removing the tube immediately upon patient gagging is not the most appropriate first step. Gagging is a common reflex during nasogastric tube insertion and can often be managed without removing the tube.
Premature removal could lead to unnecessary discomfort for the patient and potential delays in treatment.
The nurse should attempt to reposition the tube or have the patient sip water to facilitate passage before considering removal.
Choice B rationale:
Tucking the chin to the chest and swallowing are essential maneuvers that help guide the tube into the esophagus and reduce the risk of misplacement into the trachea.
These actions close off the airway and open the esophagus, creating a smoother path for the tube.
The nurse should instruct the patient to perform these actions during insertion to promote successful placement.
Choice C rationale:
While a supine position is often used for nasogastric tube insertion, it is not the most crucial factor for success.
Studies have shown that a high-Fowler's position (sitting upright with head elevated) may be equally effective and potentially more comfortable for patients.
The nurse should consider patient comfort and potential contraindications (such as respiratory distress) when choosing the most appropriate position.
Choice D rationale:
Measuring the tube from the nose tip to the navel is an outdated practice that can lead to inaccurate placement. The correct measurement is from the nose tip to the earlobe to the xiphoid process (NEX).
This landmark-based method provides a more reliable estimation of the distance to the stomach.
Correct Answer is B
Explanation
Choice A rationale:
The spinal cord plays a crucial role in pain transmission, but it does not initiate the afferent pathways. It receives pain signals from nociceptors and relays them to the brain for processing.
The spinal cord is also involved in pain modulation, as it can dampen or amplify pain signals depending on various factors. However, it is not the primary trigger for pain sensation. That role belongs to nociceptors.
Choice B rationale:
Nociceptors are specialized sensory receptors that detect potentially damaging stimuli, such as intense heat, pressure, or chemical irritants.
They are located throughout the body, including the skin, muscles, joints, and internal organs.
When nociceptors are activated, they generate electrical signals that travel along nerve fibers to the spinal cord and brain. This process initiates the afferent pathways, which ultimately lead to the conscious perception of pain.
Nociceptors are essential for protecting the body from harm. They alert us to potential dangers and trigger responses that help us avoid injury or further damage.
Choice C rationale:
Endorphins are natural pain-relieving substances produced by the body. They act on receptors in the brain and spinal cord to reduce pain perception.
However, endorphins do not trigger the afferent pathways. They work by modulating pain signals that have already been initiated by nociceptors.
Choice D rationale:
The cortex is the outer layer of the brain that is responsible for higher-level functions, such as thinking, feeling, and decision- making.
It plays a role in the conscious experience of pain, but it does not trigger the afferent pathways.
The cortex receives pain signals from the spinal cord and processes them, leading to the awareness of pain.
