A nurse is assessing a client's immune function by reviewing the laboratory value of the cellular response of the T-cells. The nurse should recognize that which of the following conditions is affected by the T-cells?
Hay fever allergy
Anaphylaxis
Transplant rejection
Bacterial phagocytosis
The Correct Answer is C
Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.
Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.
Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.
Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.

Correct Answer is A
Explanation
Choice A: Monitor the client for hypoglycemia
When a nurse administers an incorrect insulin dose, the immediate concern is the risk of hypoglycemia, especially since the insulin dose given was for a higher blood glucose level than the actual reading. Hypoglycemia can occur when blood glucose levels drop below 70 mg/dL. Symptoms of hypoglycemia include shakiness, sweating, confusion, and in severe cases, loss of consciousness. Monitoring the client for hypoglycemia allows the nurse to detect and treat it promptly, ensuring the client’s safety.
Choice B: Complete an incident report
While completing an incident report is important for documenting the medication error and preventing future occurrences, it is not the immediate priority. The nurse’s first responsibility is to ensure the client’s safety by addressing the potential hypoglycemia. Once the client’s condition is stable, the nurse can then complete the incident report.
Choice C: Give the client 15 to 20 g of carbohydrate
Administering 15 to 20 grams of carbohydrate is a treatment for hypoglycemia. However, this action should only be taken if the client is actually experiencing hypoglycemia. The nurse should first monitor the client’s blood glucose levels to confirm hypoglycemia before administering carbohydrates.
Choice D: Notify the nurse manager
Notifying the nurse manager is important for accountability and to ensure that appropriate follow-up actions are taken. However, it is not the immediate priority. The nurse should first monitor the client for hypoglycemia and address any immediate health concerns before notifying the nurse manager.
Correct Answer is A
Explanation
Choice A reason:
In the case of burns to the face and chest, assessing for inhalation injuries is critical due to the potential for airway compromise. Inhalation injuries can lead to significant respiratory distress and are considered a high priority in burn care. Inspecting the mouth for soot, burns, or edema can provide immediate information about the potential for respiratory complications, which can be life-threatening.
Choice B reason:
While monitoring urine output is important in burn patients for assessing fluid balance and kidney function, it is not the immediate priority. The insertion of an indwelling urinary catheter can be performed after stabilizing the airway and ensuring the patient is breathing adequately.
Choice C reason:
A CBC count is important for evaluating the patient's overall health status and can indicate the presence of infection or anemia. However, it is not the first action to take in the emergency setting where immediate life-saving interventions are prioritized.
Choice D reason:
Administering intravenous pain medication is important for patient comfort and can facilitate further care, but it is not the first priority. The initial focus should be on life-saving measures such as securing the airway and assessing for inhalation injuries.
