A nurse is caring for a client who has heart failure and respiratory arrest. What should be the nurse’s first action?
Auscultate for breath sounds.
Establish an open airway.
Establish IV access.
Feel for a carotid pulse.
The Correct Answer is B
Establishing an open airway is the most crucial and immediate action in any respiratory arrest situation, including when a client has heart failure. Here's a detailed explanation: 1. Airway patency is paramount for survival: Oxygen, the essential element for life, cannot reach the lungs and bloodstream without a clear and unobstructed airway. Brain cells are extremely sensitive to oxygen deprivation and start to die within minutes without it, leading to irreversible brain damage or death. 2. Respiratory arrest in heart failure: Heart failure often leads to fluid buildup in the lungs (pulmonary edema), which can significantly impair breathing. Respiratory arrest can occur due to: Excessive fluid accumulation in the lungs. Weakening of respiratory muscles due to fatigue or heart failure itself. Arrhythmias or heart blocks affecting heart's ability to pump effectively. 3. Steps to establish an open airway: Head tilt-chin lift maneuver: Gently tilt the head back and lift the chin to open the airway. Jaw thrust maneuver: If a neck injury is suspected, use the jaw thrust maneuver to avoid further injury. Removal of any visible obstructions: Clear any visible foreign objects or fluids from the mouth or throat. Use of airway adjuncts: Consider using oral or nasal airways to maintain airway patency, especially if the patient is unconscious.
4. Rationale for other choices:
A. Auscultating for breath sounds: While important for assessment, it does not address the immediate need to establish airflow.
C. Establishing IV access: IV access is necessary for medications and fluids, but airway takes priority in respiratory arrest.
D. Feeling for a carotid pulse: Checking for a pulse is essential, but only after ensuring an open airway and attempting to restore breathing.
5. Importance of prioritizing airway: Establishing an open airway allows for potential rescue breaths and ventilation, which can help restore oxygen levels and prevent further deterioration. Even if a pulse is present, without a clear airway, oxygen cannot reach the vital organs, leading to organ failure and death.

Correct Answer is D
Explanation
Rationale for Choice A: Obtain vital signs
While obtaining vital signs is important in assessing a patient's overall condition, it is not the first priority in a suspected transfusion reaction.
Vital signs can provide valuable information about the severity of the reaction, but they should not delay the immediate action of stopping the transfusion.
Delaying the cessation of the transfusion could allow for further infusion of incompatible blood or allergens, potentially worsening the reaction and leading to more serious complications.
Rationale for Choice B: Notify the registered nurse
Involving other healthcare professionals is crucial in managing transfusion reactions, but it should not precede stopping the transfusion.
The nurse should prioritize stopping the transfusion to prevent further exposure to potential triggers and then promptly notify the registered nurse for further assessment and interventions.
Timely communication with the registered nurse is essential for coordinating care and ensuring appropriate treatment measures are implemented.
Rationale for Choice C: Administer diphenhydramine
Diphenhydramine, an antihistamine, can be used to treat allergic reactions, but it should not be administered as the first response in this scenario.
The priority is to halt the infusion of the blood product that is potentially causing the reaction.
Administering diphenhydramine before stopping the transfusion could mask the symptoms of the reaction, making it more difficult to assess its severity and progression.
Rationale for Choice D: Stop the transfusion
This is the correct and most immediate action to take when a patient develops itching and hives during a blood transfusion.
These symptoms are indicative of a possible allergic or transfusion reaction, and stopping the transfusion is essential to prevent further complications.
It's critical to act quickly to minimize the amount of incompatible blood or allergens that enter the patient's circulation.
By stopping the transfusion, the nurse can potentially prevent the reaction from worsening and safeguard the patient's well- being.
Correct Answer is A
Explanation
Choice A rationale:
Hypovolemic shock is a life-threatening condition that occurs when the body loses a significant amount of blood or fluids, leading to a decrease in circulating blood volume. This can result in inadequate perfusion of organs and tissues, which can cause damage and even death if not treated promptly.
In this case, the athlete's symptoms and vital signs are consistent with hypovolemic shock. The athlete has been practicing twice a day in the heat, which can lead to significant fluid loss through sweating. The athlete is also dizzy, which is a common symptom of hypovolemia due to decreased blood flow to the brain. The athlete's blood pressure is low (100/2 mm Hg), pulse rate is elevated (100 beats/minute), and respiratory rate is increased (26 breaths/minute), all of which are compensatory mechanisms to try to maintain blood pressure and perfusion in the setting of hypovolemia. The athlete's skin is cool to touch
and pale in color, which is due to decreased blood flow to the skin. The athlete also does not remember the last voiding time, which may indicate decreased urine output, another sign of hypovolemia.
Key points supporting hypovolemic shock:
Significant fluid loss due to exercise in the heat Dizziness
Low blood pressure Elevated pulse rate Increased respiratory rate Cool, pale skin
Decreased urine output Additional details:
Hypovolemic shock can be caused by various factors, including:
Hemorrhage (blood loss) Severe dehydration Burns
Severe vomiting or diarrhea
Treatment for hypovolemic shock typically involves:
Intravenous fluid replacement to restore circulating blood volume Blood transfusion if the shock is due to hemorrhage
Oxygen therapy to support breathing
Medications to support blood pressure and heart function
