A client with a history of asthma and bronchitis arrives at the clinic with shortness of breath, productive cough with thickened, tenacious mucus, and the inability to walk up a flight of stairs without experiencing breathlessness.
Which action is most important for the nurse to instruct the client about self-care?
Increase the daily intake of oral fluids to liquefy secretions.
Call the clinic if undesirable side effects of medications occur.
Teach anxiety reduction methods for feelings of suffocation.
Avoid crowded enclosed areas to reduce pathogen exposure.
The Correct Answer is A
Choice A rationale:
Liquefying secretions is the most crucial action to address the client's immediate respiratory concerns. Thickened mucus obstructs airflow, leading to shortness of breath, productive cough, and difficulty breathing upon exertion. Increasing fluid intake thins mucus, making it easier to expel and improving ventilation. This directly addresses the client's current symptoms and promotes airway clearance.
Hydration and Mucociliary Clearance: Adequate hydration is indispensable for optimal mucociliary clearance, the natural mechanism that removes mucus from the airways. Fluids moisten the respiratory tract, allowing cilia (tiny hair-like structures) to effectively move mucus upwards, where it can be coughed out or swallowed.
Thinning Mucus: Water acts as a natural expectorant, thinning mucus and reducing its viscosity. This makes it easier for the client to cough up the mucus, clearing the airways and reducing the sensation of breathlessness.
Decreasing Mucus Production: Dehydration can trigger the body to produce more mucus as a protective response. By staying hydrated, the client can help prevent excessive mucus production, further easing symptoms.
Supporting Overall Respiratory Health: Proper hydration maintains the health of the respiratory system's tissues and cells, promoting efficient gas exchange and reducing inflammation.
Preventing Dehydration-Related Complications: Dehydration can exacerbate respiratory problems and lead to other complications, such as fatigue, headaches, and impaired immune function. Maintaining adequate fluid intake helps prevent these issues.
Key points to emphasize to the client:
Drink fluids throughout the day, even if not feeling thirsty.
Water is the best choice, but clear broths, juices, and herbal teas can also contribute to fluid intake. Avoid caffeine and alcohol, as they can be dehydrating.
Monitor urine output to ensure adequate hydration (urine should be pale yellow or clear).
Increase fluid intake during periods of increased mucus production, such as during respiratory infections or exercise.

Correct Answer is D
Explanation
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.
Correct Answer is ["B","E","G"]
Explanation
B. Position the patient with the head of the bed elevated. Rationale:
Promotes lung expansion: Elevating the head of the bed by at least 30 degrees utilizes gravity to assist in diaphragmatic descent and lung expansion. This allows for greater intake of air, optimizing oxygen intake and facilitating better gas exchange.
Reduces work of breathing: When upright, the abdominal muscles can more effectively aid in breathing, reducing the workload on the diaphragm and accessory muscles. This conserves energy and decreases the patient's respiratory effort.
Enhances secretion drainage: Gravity also aids in the movement of secretions from the lower lobes of the lungs towards the upper airways, where they can be more easily coughed up or suctioned. This helps to clear the airways and improve ventilation.
E. Teach the patient to cough at least once an hour. Rationale:
Clears secretions: Coughing is a natural mechanism to clear secretions from the lungs and airways. It helps to prevent mucus buildup and potential obstruction, which can lead to atelectasis (collapse of lung tissue) and further compromise ventilation.
Improves gas exchange: By removing secretions, coughing allows for better airflow and gas exchange within the lungs. This enhances oxygenation and helps to prevent respiratory complications.
G. Assist the patient in ambulating safely. Rationale:
Mobilizes secretions: Ambulation encourages movement of secretions from the lower lobes of the lungs, promoting their clearance and preventing mucus buildup.
Prevents atelectasis: Walking and movement help to expand the lungs, reducing the risk of atelectasis and improving overall ventilation.
Enhances circulation: Ambulation also improves circulation, which can help to deliver oxygen to the tissues more effectively and aid in healing.
