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 C
Explanation
Choice A reason:
While explaining discharge instructions is an important part of patient education and ensuring safety after leaving the hospital, it is not the immediate priority. The nurse must first address any potential medical issues that could compromise the patient's health, such as circulation and nerve function in the affected limb.
Choice B reason:
Applying an ice pack to the casted leg can help reduce swelling and provide comfort to the client. This is often recommended for the first 24 to 72 hours after the cast is applied, especially if the cast is on a leg. However, this is secondary to assessing the neurovascular status of the limb.
Choice C reason:
Performing a neurovascular assessment is the priority action for the nurse. This assessment includes checking for sensation, warmth, capillary refill, pulses, and movement. It is crucial to identify any signs of compromised blood flow or nerve injury early to prevent further complications.
Choice D reason:
Providing reassurance to the client and parents is important for emotional support and can help alleviate anxiety. However, the nurse's immediate priority is to ensure the physical well-being of the client, which includes performing a neurovascular assessment to detect any urgent issues.
Correct Answer is D
Explanation
Choice A reason:
While pulmonary function studies are an important part of the preoperative assessment and postoperative follow-up for lung cancer patients, they are not typically something a patient would be immediately prepared for post-lobectomy. These studies are usually scheduled for a later date to assess the impact of the surgery on lung function.
Choice B reason:
A sternal incision is not commonly associated with a lobectomy, which involves an incision in the chest wall, not the sternum. Sternal incisions are more often related to procedures that require access to the heart or the central chest area, such as open-heart surgery.
Choice C reason:
Moderate pain is expected after any major surgical procedure, including a lobectomy. However, pain management is a standard part of postoperative care, and patients are typically informed about pain control measures rather than being prepared to expect pain as a postoperative event.
Choice D reason:
The placement of a chest tube is a standard part of care following a lobectomy. The chest tube allows for drainage of fluid and air from the pleural space, ensuring proper lung expansion and preventing complications such as pneumothorax. Patients should be educated about the chest tube's purpose, care, and the sensations they may experience while the tube is in place.
