Your patient is a 46-year-old male who is unconscious on his front lawn after being stung by a bee. You note angioneurotic edema. HR= 132, BP= 76/40, RR= 24 and shallow. You should first:
A. Assist ventilations with 100% oxygen via a BVM
B. start an IV of NS wide open and administer epinephrine 1:10,000 IV
C. intubate the patient
D. administer epinephrine 1:1,000 SQ
A.
Assist ventilations with 100% oxygen via a BVM
Your patient is a 31-year-old female complaining of dizziness breathing after being stung by a bee. You note that she is extremely anxious, and your physical examination reveals a rapidly developing urticarial to her shoulders, neck, and face. While you are performing your PE and interview, your partner has administered oxygen via a nonrebreather, initiated IV access, placed the patient on the cardiac monitor, and administered epinephrine SQ and diphenhydramine IV. Despite this, you also note that her voice is quickly becoming more hoarse and that she has developed expiratory wheezes in all lung fields. HR= 128, BP= 100/70, RR= 20, SaO2= 99%. What should be your major concern at this point, and what is the most appropriate treatment?
A. Laryngeal edema leading to total airway occlusion; intubate
B. Increased bronchospasm leading to respiratory arrest; administer albuterol via nebulizer
C. Increased bronchospasm leading to respiratory arrest; administer epinephrine IV
D. Hypotension leading to cardiovascular collapse; administer fluids wide open and initiate a dopamine infusion
A.
Laryngeal edema leading to total airway occlusion; intubate
Which of the following signs indicates aggressive airway maintenance in a patient experiencing an anaphylactic reaction?
A. Expiratory wheezing
B. Generalized rash
C. Urticaria
D. Stridor
D.
Stridor
Your patient is a 60-year-old male who is conscious and alert, sitting on a toilet. He appears to be in moderate distress and complains of nausea and diarrhea. The patient states that her is allergic to eggs and accidentally are pancakes make with eggs this morning. He describes a 4-hour history of severe diarrhea and vomiting. HR= 124, BP= 92/60, RR= 16, SaO2 = 98%. The physical examination reveals no urticarial or angioedema; his shin is cool and clammy, and his lung sounds are clear. Based on these findings, what should be your greatest concern?
A. Cardiac arrest due to ventricular dysrhythmia
B. None; there is no immediate life threat, because this is largely a matter of discomfort
C. Respiratory failure
D. Acute dehydration and cardiovascular collapse
D.
Acute dehydration and cardiovascular collapse
Your patient is a conscious and alert 22-year-old female who was stung by a hornet. She states that she has “allergies to bee stings” and has been told that she could die if stung Your physical examination reveals a 1-cm-diameter, red, edematous area where she was stung on the left forearm. Her skin is warm and dry, and her lung sounds are clear and equal bilaterally. HR = 112 and regular, BP= 122/82, RR= 12 and regular, SaO2 =98%. The most appropriate treatment for this patient would include:
A. BLS transport to the nearest facility
B. 100% oxygen via nonrebreather mask 15 lpm, cardiac monitor, IV of NS 1-2L, epinephrine 1:1,000 0.3mg SQ diphenhydramine 25mg IV, transport
C. 100% oxygen via nonrebreather mask 15 lpm, cardiac monitor, IV of NS KVO, epinephrine 1:1,000 0.3mg SQ diphenhydramine 25mg IV, transport
D. 100% oxygen via nonrebreather mask, cardiac monitor, IV of NS KVO, transport
D.
100% oxygen via nonrebreather mask, cardiac monitor, IV of NS KVO,
You are called to the home of a 28-year-old male who is complaining of hoarseness, a scratchy sensation in the back of hid throat, and palpitations. The symptoms began about 30 minutes ago and have grown steadily worse ever since the patient ingested prescribed penicillin 1 hour ago. Patient management should include all of the following EXCEPT:
A. IV of NS KVO
B. epinephrine 1:1000 0.3 mg SQ
C. administration of an IV beta-blocker
D. supplemental oxygen via nonrebreather mask
C.
administration of an IV beta-blocker
Which treatment would best halt the urticarial associated with an allergic reaction?
A. Epinephrine SQ and diphenhydramine IM
B. Solu-Medrol IV
C. Oxygen via nonrebreather mask 15 lpm
D. Dopamine IV infusion and albuterol via nebulizer
A.
Epinephrine SQ and diphenhydramine IM
Which of the following statements about antihistamine use in anaphylaxis treatment is TRUE?
A. Blocking of H1 receptors results in mild vasoconstriction, while the blocking of H2 receptors resulted in bronchodilation
B. Antihistamine block H1 and H2 receptors and prevent further release of histamine from B and T cells.
C. Antihistamines block histamine receptors and reduce histamine release from mast cells and basophils
D. Antihistamines displace histamine and then block histamine receptors
A
Blocking of H1 receptors results in mild vasoconstriction, while the blocking of H2 receptors resulted in bronchodilation
Which of the following statements about vasopressors use in anaphylaxis treatment is TRUE?
A. A norepinephrine infusion encourages a net movement of plasma from the intravascular space to the vascular space, raising blood pressure.
B. An epinephrine infusion can correct the peripheral vasodilation that occurs secondary to SRS-A release by basophils and mast cells
C. A norepinephrine infusion can correct the peripheral vasodilation that occurs secondary to SRS-A release by basophils and mast cells
