The nurse in an allergy clinic is educating a new patient about the pathology of the patients health problem. What response should the nurse describe as a possible consequence of histamine release?
- A. Constriction of small venules
- B. Contraction of bronchial smooth muscle
- C. Dilation of large blood vessels
- D. Decreased secretions from gastric and mucosal cells

A nurse is aware of the need to assess patients risks for anaphylaxis. What health care procedure constitutes the highest risk for anaphylaxis?
- A. Administration of the measles-mumps-rubella (MMR) vaccine
- B. Rapid administration of intravenous fluids
- C. Computed tomography with contrast solution
- D. Administration of nebulized bronchodilators
Correct Answer: C
Rationale: Radiocontrast agents present a significant threat of anaphylaxis in the hospital setting. Vaccinations less often cause anaphylaxis. Bronchodilators and IV fluids are not implicated in hypersensitivity reactions.
A patient has been admitted to the emergency department with signs of anaphylaxis following a bee sting. The nurse knows that if this is a true allergic reaction the patient will present with what alteration in laboratory values?
- A. Increased eosinophils
- B. Increased neutrophils
- C. Increased serum albumin
- D. Decreased blood glucose
Correct Answer: A
Rationale: Higher percentages of eosinophils are considered moderate to severe eosinophilia. Moderate eosinophilia is defined as 15% to 40% eosinophils and is found in patients with allergic disorders. Hypersensitivity does not result in hypoglycemia or increased albumin and neutrophil counts.
The nurse is creating a care plan for a patient suffering from allergic rhinitis. Which of the following outcomes should the nurse identify?
- A. Appropriate use of prophylactic antibiotics
- B. Safe injection of corticosteroids
- C. Improved skin integrity
- D. Improved coping with lifestyle modifications
Correct Answer: D
Rationale: The goals for the patient with allergies may include restoration of normal breathing pattern, increased knowledge about the causes and control of allergic symptoms, improved coping with alterations and modifications, and absence of complications. Antibiotics are not used to treat allergies and corticosteroids, if needed, are not administered parenterally. Allergies do not normally threaten skin integrity.
A patient with multiple food and environmental allergies tells the nurse that he is frustrated and angry about having to be so watchful all the time and wonders if it is really worth it. What would be the nurses best response?
- A. I can only imagine how you feel. Would you like to talk about it?
- B. Lets find a quiet spot and Ill teach you a few coping strategies.
- C. Thats the same way that most patients who have a chronic illness feel.
- D. Do you think that maybe you could be managing things more efficiently?
Correct Answer: A
Rationale: To assist the patient in adjusting to these modifications, the nurse must have an appreciation of the difficulties encountered by the patient. The patient is encouraged to verbalize feelings and concerns in a supportive environment and to identify strategies to deal with them effectively. The nurse should not suggest that the patient has been mismanaging his health problem and the nurse should not make comparisons with other patients. Further assessment should precede educational interventions.
