A nurse is caring for a client who has a hemoglobin of 10.8 g/dL and a hematocrit of 30%. The nurse should expect the client is at risk for which of the following conditions?
Cellular hypoxia
Fluid retention
Prolonged bleeding
Impaired immunity
The Correct Answer is A
Choice A rationale:
Cellular hypoxia occurs when cells do not receive enough oxygen to meet their metabolic demands. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the tissues. A hemoglobin level of 10.8 g/dL is below the normal range for adults (14-18 g/dL), indicating that the client has anemia. Anemia reduces the oxygen-carrying capacity of the blood, which can lead to cellular hypoxia.
Here is a detailed explanation of how anemia can lead to cellular hypoxia:
Decreased oxygen-carrying capacity: Anemia results in fewer red blood cells or reduced hemoglobin levels within those cells. As a consequence, the blood's ability to transport oxygen to the tissues is diminished.
Impaired oxygen delivery: Oxygen is transported to the tissues through the bloodstream, attached to hemoglobin within red blood cells. With fewer red blood cells or reduced hemoglobin, the delivery of oxygen to the tissues is compromised.
Decreased oxygen availability at the cellular level: As oxygen delivery is impaired, less oxygen is available to the cells for metabolic processes. This insufficient oxygen supply leads to cellular hypoxia.
Impaired cellular function: Cells require oxygen to produce energy through a process called aerobic respiration. Cellular hypoxia disrupts this process, leading to impaired cellular function.
Tissue and organ dysfunction: When a significant number of cells within a tissue or organ experience hypoxia, the function of that tissue or organ can be compromised. This can manifest in various symptoms and complications, depending on the affected organs.
Common signs and symptoms of cellular hypoxia:
Fatigue Weakness
Shortness of breath Pale skin
Dizziness Headache Chest pain
Tachycardia (rapid heart rate) Cognitive impairment

Correct Answer is D
Explanation
The correct answer is choiceD.
Choice A rationale:
Assisting the client back into bed is not the initial action.Moving the client without assessing their condition could potentially cause harm.
Choice B rationale:
Notifying the client’s provider is important, but it should be done after assessing the client’s condition to provide accurate information.
Choice C rationale:
Informing the client’s family member is not the immediate priority.The nurse should first ensure the client’s safety and assess their condition.
Choice D rationale:
Obtaining the client’s vital signs is the initial action.This helps assess the client’s current condition and determine if there are any immediate medical needs.
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.
