A nurse is teaching parents how to use an Epi-Pen for their child, who has a peanut allergy. Which statement by the parents indicates understanding of the teaching? a. “After using the Epi-Pen, we must go to the emergency department.” b. “The Epi-Pen should be stored inthe refrigerator, because epinephrine issensitive to heat.” c. “The teacher should call us when symptoms start so that we can bring the Epi-Pen to school.” d. “We should jab the device into the thigh until it is empty of solution.” ANS: A After using the Epi-Pen, it is important that the individual get medical attention as quickly as possible. The effects of epinephrine fade in 10 to 20 minutes, and the anaphylactic reaction can be biphasic and prolonged. Epinephrine is sensitive to heat, but storing the device in the refrigerator can compromise the injection mechanism; the device should be stored at room temperature in a dark place. Individuals who need an Epi-Pen must have the device with them at all times; any delay in treatment can be fatal, because anaphylaxis can occur within minutes after exposure. The EpiPen contains 2 mL of epinephrine, but only 0.3 mL is injected; the device will not be empty with a successful injection.DIF: Cognitive Level: ApplicationREF: pp. 116TOP: Nursing Process: Evaluation MSC: NCLEX Client Needs Category: Physiologic Integrity: Pharmacologic and Parenteral Therapies 52. A nursing student asks the nurse why epinephrine, and not other adrenergic agonists, isused to treat anaphylactic shock. What will the nurse tell the student? a. “Epinephrine is the only adrenergic agonist that may be given parenterally.” b. “Epinephrine has the ability to activate multiple types of adrenergic receptors.” c. “Other adrenergic agonists have more severe adverse effects and are not safe in the doses needed to treat anaphylaxis.” d. “Other adrenergic agonists have little or no effects on beta2-adrenergic receptors.” ANS: B Downloaded by: chelle | Distribution of this document is illegal Downloaded by: Studypool | Distribution of this document is illegal S - The Marketplace to Buy and Sell your Study Material S - The Marketplace to Buy and Sell your Study Material Epinephrine is used to treat anaphylactic shock because of its ability to activate multiple adrenergic receptor types. Activation of beta1 receptors helps to increase cardiac output and improve blood pressure as well as suppress glottal edema. Activation of beta2 receptors helps to counteract bronchoconstriction. Activation of alpha1 receptors also causes vasoconstriction, which improves blood pressure. Isoproterenol may also be given parenterally but does not activate multiple receptor types. Other adrenergic agonists, such as albuterol, are more specific to beta2 receptors and have fewer side effects.DIF: Cognitive Level: ApplicationREF: pp. 114TOP: Nursing Process: Implementation MSC: NCLEX Client Needs Category: Physiologic Integrity: Pharmacologic and Parenteral Therapies.
