Case Study: Poppy

Solution 1: Pathogenesis of Asthma

Asthma is a chronic condition associated with the inflammation of the airways. This inflammation could be triggered by an allergen cascading an immunogenic response involving the neutrophils, eosinophils, mast cells, lymphocytes and the epithelial cells in the respiratory tract (Carpaijj et al., 2019). The airway flow in the respiratory tract is constricted in asthma leading to shortness of breath in the patient. This constriction in acute exacerbated asthma is a direct consequence of bronchoconstriction, which is smooth muscle contraction narrowing the airway passage. At a molecular level, the concentration of immunoglobulin E is increased in the pathway triggering the reaction of the immune system of the body. This results in hyperresponsiveness of the body and leading to airway inflammation. This inflammation works as a direct hindrance to the airflow causing breathing difficulties and causing asthma (Boulet, 2017).

Solution 2:

Part A: High Fowlers Positioning in Respiratory Distress.

The high fowler's position angles the patient to 30degrees to 90degrees. This facilitates the relaxation of tension built in the abdominal muscles and thus aids in breathing. The position releases the compression pressure on the chest that occurs due to gravity and assists the patient in breathing (Sousa &Warren, 2017).

Part B: i) Suitable Oxygen Device: Nasal Cannula

ii) Rationale for selection: Nasal cannula is an efficient means to provide high flow oxygen therapy to manage asthma. The device is used to provide supplemented oxygen to a patient with breathing difficulties like asthma. The device is a composite of a tube that splits into prongs placed inside the nostrils of the patient through which supplemented airflow is provided (Boulet, 2017).

iii) mode of function of supplemented oxygen: supplemented oxygen reduces the negative drain created by reduced oxygen saturation and provides the lungs with extra oxygen by opening up the airways (Boulet, 2017).

Solution 3:

Part A: Salbutamol via Nebulizer

i)Mechanism of action: Salbutamol acts as an antagonist to the selective beta2-adrenoceptor. The drug acts on the receptors of the bronchial muscles and dilates them. This phenomenon is known as bronchodilation. The mechanism of action of this drug is fast as it acts within five minutes of administration (Zhou et al., 2017).

ii)Rationale for medication: One of the essential goals to improve the condition of the patient in the case study is to bring the oxygen saturation levels of the patient to normal. The administration of salbutamol via nebulizer will cause bronchodilation and improve the respiration in the patient by easing the breathing cycle. As the constriction in the airway passage is removed, the airflow will be restored and the oxygen saturation levels in the patient will be restored to normal.

iii)Nursing considerations of medication: The nurse must take care of the side effects of the medication. These include anxiety and heart pacing. Therefore, the nurse needs to check the heart rate and blood pressure of the patient before and after administration of the drug. Patient history must be collected and if the patient shows allergy towards amines, this drug should be restricted. It is also prohibited in patients who are hypertensive and have cardiac problems that may be elevated by this drug (Zhou et al., 2017).

iv)Expected clinical response: The expected clinical responses include normalization of oxygen saturation levels, normalization of respiratory rates and ease in breathing in a patient. Restoration of heart and blood pressure to normal (Zhao et al., 2020).

v) Continuing clinical observations required: The clinical assessments include analysis of lung sounds, evaluation of vitals, blood pressure and heart rate evaluation before and after administration of the medication. In case of presence of cough, the nature of cough and sputum must be analyzed (Zhao et al., 2020).

Part B: Hydrocortisone IV

i)Mechanism of action: Hydrocortisone IV is a corticosteroid by nature. The medication is used in asthma as it enhances the beta-adrenergic response and eases the muscle spasm in the patient. The drug also functions by reversing the mucosal edema that may be a cause of airway hindrance. The drug decreases the vascular permeability through vasoconstriction and inhibits the release of LTD4 and LTC4 aiding an asthmatic patient in breathing (Adlan et al., 2018).

ii)Rationale for medication: the drug has been prescribed as it is found to be effective in the treatment of asthma. The drug clears out the airways and allows the patient to breathe more easily this aid in providing relief to the patient. The drug is used largely in conjugation with prednisone to cure acute asthma as it aids in clearing the airway easing respiration through an anti-inflammatory effect on the body (Barabutis et al., 2017)

iii)Nursing considerations of medication: The drug administration causes an elevation in blood pressure. Therefore, the blood pressure and the heart rate of the patient before and after drug administration must be critically monitored. It may also cause side effects like headaches, fluid retention and puffiness on the face (Adlan et al., 2018).

iv)Expected clinical response: the expected clinical response will be normalization of the vitals. That is the restoration of the blood pressure and heart rate of the patient along with regularization of the oxygen saturation levels in the patient and overall improvement in the breathing cycle (Barabutis et al., 2017).

v) Continuing clinical observations required: Monitoring of vitals and analyzing the response to the medication is critical (Adlan et al., 2018).

Part C: Ipratropium Bromide via Nebulizer

i)Mechanism of action: Ipratropium Bromide is a parasympatholytic agent that is an anticholinergic agent and functions by blocking the muscarinic receptors of acetylcholine. The medication functions as a bronchodilator and enlarged the airway for smooth passage of air for the ease of breathing. It dilates the bronchi in the respiratory system and smoothens the translocation of air for the ease of respiration in the patient (Saab & Aboeed, 2019).

ii)Rationale for medication: The drug acts fast and has a long-lasting effect on patients with breathing difficulties. The drug eases the bronchi and opens the airway for easier respiration and breathing in patients with airway constriction (Saab & Aboeed, 2019).

iii)Nursing considerations of medication: Several nursing considerations are associated with the administration of this medication. It must be noted that the administration of this drug in the patient can lead to buccal ulceration, dry mouth, headache, constipation, nausea, paradoxical bronchospasm, acute angle-closure glaucoma, immediate hypersensitivity, epistaxis, nasal dryness and paralytic ileus in adverse conditions. If the patient is allergic it may trigger and anaphylaxis reaction and super ventricular tachycardia (Beltaief et al., 2019). Therefore, it is essential for nurses to gather a comprehensive patient history. Further, the solution must be stored in dark and not to be brought in light, it is advised to mix the albuterol in the nebulizer for up to one hour. The hydration of the patient must be maintained to prevent incidences of hyperpyrexia (Saab & Aboeed, 2019).

iv)Expected clinical response: the patient response is expected to improve with better breathing due to clearing of the airways and bronchodilation this should result in restoration of the patient vitals including the normalization of the blood pressure, heart rate and oxygen saturation in the patient (Beltaief et al., 2019).

v) Continuing clinical observations required: The vitals of the patient must be essentially monitored to see improvements, the drug dose must be monitored and provided only as per the clinical prescription. The blood pressure, heart rate and oxygen saturation levels must be monitored regularly until normalized. Positioning may be done to enhance the recovery of the patient (Beltaief et al., 2019).
