Description:The alarm stage of GAS is often accompanied by increased mental alternes, initiation of endocrine activity and vasoconstriction. Exhaustion stage is often accompanied by decreased blood pressure and vasodilation.

Description:Disturbed sleep patterns are often treated with appropriate sedative and hypnotics. Defensive coping, ambivalence and disturbed process (e.g., Delusion) are less amenable to short-term pharmacological treatment.

Description:Cortisol is a hormone that plays several important roles in the body. It helps regulate various processes, including immune response, blood sugar levels, and metabolism. However, it does not have a direct role in increasing the body's inflammatory response. This means that among the given options, the correct answer is c. Increased inflammatory response.

Description:The stress hormone cortisol can affect different parts of the brain. Among the options provided, the area that is impacted by cortisol and can lead to problems with memory function is the hippocampus. So, the answer is a. Hippocampus.

Description:The anterior pituitary produces ACTH. Corticotropin releasing hormone (CRH) is released from the hypothalamus which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.

Description:Excessive stress or high levels of cortisol, as seen in conditions like Cushing's disorder, can lead to various physical changes. Among the given options, the effect that is not associated with these conditions is hypoglycemia. The other manifestations like moon face and diminished inflammatory response can indeed be linked to excessive stress or elevated cortisol levels.

Description:Endorphins are released in response to pain or stress. Since endorphins act on the opiate receptors in our brains, they reduce pain and boost pleasure, resulting in a feeling of well-being.

Description:The client's description of feeling a vague sense of unease, dread, and experiencing a raised heart rate suggests symptoms commonly associated with anxiety. Among the provided options, the most suitable nursing diagnosis for this patient would be c. Anxiety.

Description:In the alarm stage of the General Adaptation Syndrome (GAS), which is the body's response to stress, the role of antidiuretic hormone (ADH) is to enhance fluid retention by reabsorbing water. This helps the body conserve water and maintain proper fluid balance during times of stress.

Description:The situation where an adult woman is dealing with her father's passing, taking care of her disabled mother, working full-time, and looking after her two school-going children involves multiple challenges that can affect her well-being. These challenges are collectively known as stressors. Stressors are events or circumstances that put pressure on a person, potentially causing physical or emotional strain.

Description:Vasoconstrictors are substances or medications that cause blood vessels to narrow, which can increase blood pressure. However, there are situations where using vasoconstrictors might not be appropriate. Among the options given, vasoconstrictors should not be used in hemorrhagic shock. In hemorrhagic shock, the body has lost significant amounts of blood, and the goal is to maintain blood flow to vital organs. Using vasoconstrictors could further decrease blood flow and worsen the situation. So, the correct answer is b. Hemorrhagic shock.

Description:Shock that occurs due to a severe allergic reaction is called anaphylactic shock. Anaphylactic shock happens when the body's immune system reacts strongly to an allergen, releasing chemicals that cause blood vessels to widen and blood pressure to drop rapidly. This can lead to a life-threatening situation where the body doesn't receive enough blood flow to vital organs.

Description:Shock that occurs due to a severe allergic reaction is called anaphylactic shock. Anaphylactic shock happens when the body's immune system reacts strongly to an allergen, releasing chemicals that cause blood vessels to widen and blood pressure to drop rapidly. This can lead to a life-threatening situation where the body doesn't receive enough blood flow to vital organs.

Description:When shock occurs as a result of a severe and widespread infection, it is referred to as septic shock. Septic shock happens when the body's response to an infection triggers a cascade of events that lead to a dangerous drop in blood pressure and poor circulation. Among the options provided,

Description:When a spinal cord injury disrupts the normal communication between the nervous system and the circulatory system, it can lead to a type of shock called neurogenic shock. This type of shock is characterized by a sudden drop in blood pressure and can result in poor blood circulation throughout the body. Among the options provided, the correct answer is c. Neurogenic shock.

Description:In the scenario described, if a patient has fallen from a height and is experiencing back pain along with difficulty moving the lower extremities, there is a concern for potential spinal cord injury. Neurogenic shock can occur due to such injuries and is characterized by a disruption in the normal functioning of the autonomic nervous system. Among the options given, the additional observation that indicates the patient may be experiencing neurogenic shock is b. Bradycardia, which means a slower heart rate. This can be a result of the disrupted nerve signals affecting the heart's normal rhythm regulation.

Description:In cases of anaphylactic shock, where the body has a severe allergic reaction, the drug of choice to rapidly counteract the dangerous symptoms is adrenaline (also known as epinephrine). Adrenaline helps to reverse the allergic response by constricting blood vessels, improving blood pressure, and relaxing airways to aid in breathing. Among the options provided,

Description:During an anaphylactic reaction, a critical nursing responsibility is to administer oxygen. Anaphylactic reactions can cause breathing difficulties and decreased oxygen levels in the body, so providing supplemental oxygen helps ensure that the patient receives enough oxygen to support their vital organs. While administering adrenaline, providing antidotes if available, and monitoring vital signs are also important aspects of care, ensuring adequate oxygenation is particularly crucial to prevent complications. Therefore, the correct answer is a. Administering oxygen.

Description:Anaphylactic shock is a severe allergic reaction that can occur when the immune system overreacts to an allergen. The mediator responsible for the symptoms of anaphylactic shock is histamine. Histamine is released by immune cells in response to the allergen and causes a cascade of reactions in the body, leading to symptoms such as difficulty breathing, low blood pressure, hives, and swelling. Other substances like cytokines, dopamine, and adrenaline also play roles in the body's response to allergens, but histamine is the primary mediator of anaphylactic shock.

Description:The most important nursing intervention for a client experiencing an anaphylactic reaction after taking antibiotics is b. Maintain a patent airway. This means ensuring that the person's airway (the passage through which they breathe) remains open and unobstructed. During an anaphylactic reaction, the person's airway can become swollen and blocked, making it difficult for them to breathe. By keeping the airway clear, nurses can help the person breathe and prevent a life-threatening situation. While administering an antidote, providing intravenous fluids (RL - Ringer's Lactate), and recording the reaction are also important, ensuring a clear airway takes precedence in order to ensure the person's immediate safety and well-being.

Description:Hypovolemic shock occurs when there's a significant loss of blood or fluids, leading to a decrease in the volume of blood circulating in the body. To address this condition, it's important to quickly replace the lost fluids and restore blood volume. This is done by administering fluids directly into the bloodstream through intravenous (IV) lines. This helps improve blood pressure and circulation, which are crucial for the body's functioning. While relieving pain, administering vasodilators (medications that relax blood vessels), and giving antibiotics might be relevant in certain situations, the immediate priority in treating hypovolemic shock is to replenish the lost fluids, making option c the most appropriate choice.

Description:Trendelenburg position is when the person's head is lowered and the feet are raised, tilting the body at an angle. This position helps improve blood flow to the brain and vital organs by utilizing gravity to increase blood return to the heart. It's commonly used in cases of shock to help stabilize blood pressure and circulation. While Fowler's position (sitting up slightly), prone position (lying face down), and supine position (lying flat on the back) might be used in different medical scenarios, the Trendelenburg position is chosen for shock situations to assist in restoring blood flow to critical areas of the body.

Description:Septic shock is a serious condition that occurs when the body's response to an infection causes widespread inflammation and can lead to a life-threatening drop in blood pressure. The pathophysiology of septic shock involves multiple factors: a. Vasodilation: This is the widening of blood vessels. In septic shock, the body releases various chemicals that cause blood vessels to dilate. This can lead to a decrease in blood pressure. b. Decreased cardiac output: The heart's ability to pump blood effectively can be compromised in septic shock due to the body's inflammatory response. This can contribute to a reduction in blood flow to vital organs. c. Increased capillary permeability: Inflammation caused by the infection can cause capillaries (tiny blood vessels) to become more permeable, allowing fluids and proteins to leak out into surrounding tissues. This can lead to swelling and a decrease in blood volume. All these factors contribute to the complex cascade of events in septic shock, which can result in organ dysfunction and a life-threatening condition.

Description:Metabolic acidosis occurs when there is an excess of acid in the body or a loss of bicarbonate (a base) that helps regulate the body's pH. In the context of shock, various factors such as decreased blood flow, inadequate oxygen delivery, and tissue damage can lead to the buildup of lactic acid and other acidic compounds in the bloodstream. This can cause the body's pH to decrease, leading to metabolic acidosis. While shock can affect respiration and potentially cause respiratory imbalances (options a and b), metabolic acidosis is the most common acid-base disturbance associated with shock. It's important to manage this imbalance to support the body's recovery from shock

Description:Shock is a critical medical condition where the body's vital organs and tissues do not receive adequate blood flow and oxygen, leading to a cascade of physiological responses. The given statements explain different aspects of shock: a. In the early stage, cardiac output and blood pressure are maintained: In the initial phase of shock, the body attempts to compensate by increasing heart rate and constricting blood vessels to maintain blood pressure and cardiac output. This is a response aimed at preserving organ perfusion. b. Perfusion to the cells is inadequate to supply oxygen and nutrients: Despite the initial compensatory mechanisms, shock ultimately leads to inadequate perfusion, meaning that cells and tissues don't receive enough oxygen and nutrients to function properly. This can have serious consequences for the body's overall health. c. Activation of sympathetic nervous system: Shock triggers the body's sympathetic nervous system, often referred to as the "fight or flight" response. This results in increased heart rate, constriction of blood vessels, and the release of stress hormones. These responses are aimed at maintaining blood pressure and increasing blood flow to vital organs. In summary, all of these statements correctly describe various aspects of shock and its effects on the body.
