A nurse is teaching a client how to self-administer insulin. The client has a prescription for 5 units of NPH insulin and 15 units of regular insulin. Identify the sequence in which the nurse should perform the following steps. (Move the steps into the box on the right, placing them in the order of performance. Use all the steps.)

Salicylism is a toxic condition resulting from excessive salicylateaccumulation, often characterized by acid-base disturbances and neurological changes. It disrupts metabolicprocesses and affects the vestibulocochlear nerve, leading to distinct sensory impairments. Prompt recognition of early toxicity is vital to prevent severe respiratory alkalosisor metabolic acidosis.

Rationale:

A.Diplopia, or double vision, is not a hallmark sign of early salicylate toxicity or salicylism. While severe poisoning can eventually lead to central nervous system depression and visual disturbances, it is not the primary indicator used for clinical screening. The nurse should look for signs more specific to the Eighth cranial nerve and acid-base status when assessing for aspirin toxicity.

B.Joint pain is an indication for taking aspirin rather than a sign of its toxicity. Aspirin is frequently used to treat inflammatory conditions like rheumatoid arthritis or osteoarthritis due to its inhibition of cyclooxygenase. If a client continues to experience joint pain, it suggests the dosage is therapeutic or perhaps insufficient, rather than indicating an overdose or salicylism.

C.Facial edema is more indicative of a type I hypersensitivity reaction or angioedema rather than chronic salicylate toxicity. While a patient can be allergic to aspirin, this finding represents an acute immunological response rather than the metabolic syndrome of salicylism. Salicylism specifically targets the auditory system and metabolic pathways rather than causing localized soft tissue swelling.

D.Tinnitus, described as a ringing or buzzing in the ears, is the most common early clinical manifestation of salicylism. It occurs because high levels of aspirin are toxic to the hair cells within the cochlea and affect the acoustic nerve. The nurse must instruct the client that the onset of tinnitus requires immediate cessation of the medication and a medical evaluation to prevent further toxicity.

Anaphylaxis is a severe type I hypersensitivityreaction characterized by systemic mast cell degranulation and bronchoconstriction. While epinephrine is the first-line treatment for its vasopressorand bronchodilatory effects, refractory respiratory distress requires secondary interventions to stabilize the airway. Targeted beta-2 agonists are used to provide localized relief of bronchospasm.

Rationale:

A.Selegiline is a monoamine oxidase inhibitor (MAOI) used primarily in the management of Parkinson's disease. It has no role in the acute treatment of anaphylaxis or respiratory distress. Administering an MAOI in an emergency setting could actually lead to dangerous drug interactions with the epinephrine already given, potentially triggering a hypertensive crisis or cardiac arrhythmia.

B.Abatacept is a selective costimulation modulator used for the treatment of rheumatoid arthritis by inhibiting T-cell activation. It is a maintenance medication for chronic autoimmune conditions and does not provide the rapid bronchodilation required for an acute allergic emergency. Its onset of action is far too slow to address the immediate threat of airway occlusion following a bee sting.

C.Sucralfate is a gastroprotective agent that forms a complex over ulcer sites in the stomach. It is administered orally and has no systemic effect on the respiratory or cardiovascular systems. Using sucralfate in a client with severe dyspnea is inappropriate and dangerous, as the patient is at high risk for aspiration and requires immediate parenteral or inhaled interventions.

D.Albuterol is a rapid-acting beta-2 adrenergic agonist that provides direct bronchodilation to relieve the wheezing and airway constriction associated with anaphylaxis. When a client has a suboptimal response to epinephrine, inhaled albuterol helps to further relax the smooth muscles of the bronchioles. This is a critical secondary intervention to improve ventilation and reduce the work of breathing.
