A nurse is collecting data about the fluid status of four patients.
Which patient should the nurse identify as being at risk for fluid volume deficit?
A patient who has heart failure and is receiving diuretic therapy.
A patient who has gastroenteritis and is receiving oral fluids.
A patient who has end-stage kidney disease who will undergo dialysis.
A patient who has NPO status since midnight for an endoscopy.
The Correct Answer is D
Rationale for Choice A:
Diuretics promote fluid loss, increasing the risk of fluid volume deficit.
Heart failure can lead to fluid retention, but diuretic therapy is often used to manage this excess fluid.
However, in this case, the patient is receiving diuretic therapy, which suggests that their fluid status is being actively managed.
Therefore, while this patient is at risk for fluid volume deficit, they are not the most likely candidate among the options presented.
Rationale for Choice B:
Gastroenteritis can lead to fluid loss through vomiting and diarrhea.
However, this patient is receiving oral fluids, which helps to replenish lost fluids and electrolytes.
As long as the patient is able to tolerate oral fluids and is not experiencing excessive fluid losses, they are not at significant risk for fluid volume deficit.
Rationale for Choice C:
End-stage kidney disease can impair the kidneys' ability to regulate fluid balance.
However, dialysis is a treatment that helps to remove excess fluid and waste products from the body.
Therefore, while this patient is at risk for fluid volume imbalances, they are receiving treatment to manage this risk.
Rationale for Choice D:
NPO status means that the patient has been instructed to have nothing by mouth. This means that the patient has not been able to consume any fluids since midnight.
Even in the absence of excessive fluid losses, this prolonged period of fluid restriction can lead to dehydration and fluid volume deficit.
Therefore, this patient is the most likely to be experiencing fluid volume deficit among the options presented.

Correct Answer is ["A","D","E"]
Explanation
Choice A rationale:
Intravenous theophylline (aminophylline) is a bronchodilator that can be life-saving in cases of anaphylactic shock with bronchospasm. It works by relaxing the smooth muscles in the airways, allowing for increased airflow.
Anaphylactic shock can cause severe bronchospasm, which can lead to respiratory failure and death. Theophylline can help to reverse bronchospasm and improve oxygenation.
The dosage of theophylline should be individualized based on the patient's weight and severity of bronchospasm. It is important to monitor the patient's heart rate and blood pressure while administering theophylline, as it can cause tachycardia and arrhythmias.
Choice B rationale:
Culturing the site of the bee sting and administering antibiotics is not appropriate in the acute management of anaphylactic shock. Anaphylaxis is an allergic reaction, not an infection. Antibiotics will not address the underlying cause of the reaction.
Antibiotics may be necessary if the patient develops a secondary infection at the site of the bee sting. However, this is not a priority in the acute setting.
Choice C rationale:
Providing sips of water to moisten the mouth and throat is not a priority in the acute management of anaphylactic shock. The patient's primary concern is likely to be difficulty breathing.
If the patient is able to drink, it is important to ensure that they are able to do so safely without compromising their airway. However, this is not a life-saving intervention.
Choice D rationale:
Diphenhydramine (Benadryl) is an antihistamine that can help to block the effects of histamine, one of the chemicals released during an allergic reaction. This can help to reduce symptoms such as swelling, itching, and hives.
Diphenhydramine can also help to prevent further release of histamine, which can help to stop the progression of the allergic reaction.
Diphenhydramine is available over-the-counter, but it is important to consult a healthcare professional before administering it to a patient in anaphylactic shock.
Choice E rationale:
Surgical management of the airway may be necessary if the patient's airway becomes compromised due to swelling. This could include intubation or a tracheostomy.
It is important to be prepared for surgical airway management in case it is needed. Early preparation can help to prevent delays in treatment and improve the patient's chances of survival.
Correct Answer is B
Explanation
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.
