A patient's data shows consolidation in the right middle and lower lobe, consistent with pneumonia.
What actions can the nurse take to assist the patient in improving their ventilation and oxygenation? Select all that apply.

Choice A rationale:

Autoimmune responses occur when the immune system mistakenly attacks the body's own tissues. They are not typically triggered by allergens like bee stings.

Autoimmune responses often develop slowly over time and present with symptoms related to the specific tissues being attacked.

The rapid onset of symptoms in this case, along with the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of an autoimmune response.

Choice B rationale:

Type II hypersensitivity reactions involve antibodies that target and destroy cells or tissues. These reactions often take hours or days to develop, rather than minutes.

Examples of type II hypersensitivity reactions include transfusion reactions, hemolytic disease of the newborn, and some autoimmune diseases.

The rapid onset of symptoms in this case is not consistent with a type II hypersensitivity reaction.

Choice C rationale:

Cell-mediated hypersensitivity reactions involve T cells that directly attack cells or tissues. These reactions typically take 1-3 days to develop.

Examples of cell-mediated hypersensitivity reactions include contact dermatitis (e.g., poison ivy), graft-versus-host disease, and some drug reactions.

The rapid onset of symptoms in this case, as well as the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of a cell-mediated hypersensitivity reaction.

Choice D rationale:

IgE response hypersensitivity reactions are the most immediate type of allergic reaction.

They are mediated by immunoglobulin E (IgE) antibodies, which bind to mast cells and basophils.

When an allergen (like bee venom) cross-links IgE antibodies on mast cells, it triggers the release of histamine and other inflammatory mediators.

These mediators cause vasodilation, increased vascular permeability, smooth muscle contraction, and mucus secretion, leading to the characteristic symptoms of an allergic reaction.

The rapid onset of symptoms in this case, including rash, shortness of breath, and low blood pressure, are consistent with an IgE-mediated hypersensitivity reaction.

Choice A rationale:

Deep breathing and coughing exercises are not a priority intervention immediately following eye surgery. They are more commonly used to prevent postoperative pulmonary complications, such as pneumonia or atelectasis, in patients who have undergone general anesthesia or have respiratory conditions.

While deep breathing and coughing exercises can help promote circulation and prevent blood clots, they are not directly relevant to protecting the eye after surgery.

Engaging in deep breathing and coughing exercises too soon after eye surgery could potentially increase intraocular pressure, which could strain the healing eye and potentially lead to complications.

Choice B rationale:

Obtaining vital signs every 2 hours is a standard nursing intervention for monitoring a patient's overall condition, but it is not the most immediate priority following eye surgery.

Vital signs can provide important information about the patient's heart rate, blood pressure, respiratory rate, and temperature, but they do not directly address the protection of the surgically treated eye.

While monitoring vital signs is important, it does not specifically address the prevention of injury or complications to the eye itself.

Choice C rationale:

Providing an eye shield is the most crucial intervention to protect the eye immediately following surgery. The eye shield serves several important purposes:

Protection from accidental injury: It prevents the patient from accidentally rubbing or bumping the eye during sleep, which could cause further damage or disrupt the healing process.

Prevention of infection: It helps to keep the eye clean and free from debris, reducing the risk of infection. Reduction of swelling: It can help to minimize swelling and discomfort by applying gentle pressure to the eye area.

Promotion of healing: By creating a dark and protected environment, the eye shield can promote rest and healing of the tissues.

Choice D rationale:

Teaching a family member to administer eye drops is an important intervention for long-term care, but it is not the most immediate priority following surgery.

The patient may be able to administer eye drops independently, or a nurse may be responsible for administering them in the initial post-operative period.

Focusing on teaching family members about eye drop administration right after surgery could distract from more urgent priorities, such as protecting the eye with an eye shield.
