- B. Risk for Acute Pain Related to Loss of Skin Integrity
- C. Risk for Impaired Skin Integrity Related to Cutaneous Lesions
- D. Risk for Impaired Gas Exchange Related to Airway Obstruction

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.
Which of the following individuals would be the most appropriate candidate for immunotherapy?
- A. A patient who had an anaphylactic reaction to an insect sting
- B. A child with allergies to eggs and dairy
- C. A patient who has had a positive tuberculin skin test
- D. A patient with severe allergies to grass and tree pollen
Correct Answer: D
Rationale: The benefit of immunotherapy has been fairly well established in instances of allergic rhinitis and bronchial asthma that are clearly due to sensitivity to one of the common pollens, molds, or household dust. Immunotherapy is not used to treat type I hypersensitivities. A positive tuberculin skin test is not an indication for immunotherapy.
