Inhaled albuterol is the treatment of choice for an asthma exacerbation, not anaphylaxis. The goal oftreatment for anaphylaxis is the stimulation of alpha1, alpha2, beta1, and beta2receptors to aid invasoconstriction and bronchodilation. Although albuterol does activate beta2receptors, it will not treatthe underlying cause of the difficulty breathing, which is an anaphylactic reaction.Subcutaneous epinephrineEpinephrine administered subcutaneously or intramuscularly is the treatment of choice for anaphylaxis.As a catecholamine, it must be administered parenterally to exert an effect.Which information would the nurse provide to Alyssa and her parents aboutthe use of an epinephrine autoinjector (EpiPen)?Select all that apply.CASE STUDY DETAILS"Take the medication as it is prescribed.""It is acceptable to use the EpiPen when the particles are pink tobrown in color.""Keep an EpiPen available at all times, and store extramedication in a cool, dark place.""There is no need to notify the health care provider if the EpiPenis needed more than twice a week.""The EpiPen must be administered immediately upon the firstoccurrence of difficulty breathing, wheezing, hives, itching,hoarseness, or swelling of the lips and tongue."Exactly!"Take the medication as it is prescribed." Show What teaching information should the nurse offer to Alyssa and her parents about the use of the EpiPen? Select all that apply. "Take the medication as it is prescribed." "It is acceptable to use the EpiPen when the particles are pink to brown in color." "Keep an EpiPen available at all times, and store extra medication in a cool, dark place." "There is no need to notify the health care provider if the EpiPen is needed more than four times a week." "The EpiPen must be administered instantly upon the first occurrence of difficulty breathing, wheezing, hives, itching, hoarseness, or swelling of the lips and tongue." "Take the medication as it is prescribed." "Keep an EpiPen available at all times, and store extra medication in a cool, dark place." "The EpiPen must be administered instantly upon the first occurrence of difficulty breathing, wheezing,
hives, itching, hoarseness, or swelling of the lips and tongue." Which condition is contraindicated for administration of albuterol?Hypersensitivity is a contraindication for albuterol.
How would the nurse determine the effectiveness of albuterol therapy?An innovative form of ventilation with monitoring of the electrical activity of the diaphragm with a special sensor-embedded catheter is used to assess the effectiveness of albuterol administration.
Which mechanism of albuterol reduces airway resistance?Albuterol is an inhaled short-acting beta-2 agonist that stimulates beta-2 receptors on the surface of airway smooth muscle. The increased sympathetic tone causes the relaxation of airway smooth muscle, which causes dilation of the bronchi and bronchioles, reducing airway resistance.
Which drug mimics the effects of the sympathetic nervous system?Sympathomimetic Drugs and Adrenergic Receptor Antagonists
Sympathomimetics are drugs that mimic the stimulation of the sympathetic nervous system.
