A nurse is educating a patient on his medication therapy for allergic rhinitis. The patient is to take cromolyn (NasalCrom) daily
In providing educational interventions regarding this medication, which is the most important to instruct about the action of the medication?
A) It inhibits the release of histamine and other chemicals.
B) It is used to treat atrial and ventricular dysrhythmias.
C) It competitively inhibits the rate-limiting enzyme in the liver.
D) It leads to bronchodilation and relaxes smooth muscle in the bronchi.
Ans: A
Feedback: Cromolyn (NasalCrom) inhibits the release of histamine and other chemicals. It is prescribed to treat allergic rhinitis. Antiarrythmic medications are used to treat atrial and ventricular dysrythmias. HMG-CoA reductase inhibitors are used to lower blood cholesterol by competitively inhibiting the rate-limiting enzyme in the liver. Beta-adrenergic agents lead to bronchodilation and stimulate beta 2 adrenergic receptors in the smooth muscle of the bronchi and bronchioles.

What patient safety issues does this case study highlight?
A 60-year-old female patient, Mrs Teuila Afualo, presents at the day surgery unit (DSU) for an open repair of an umbilical hernia at 8 am. She is of Islander background and has brought several of her family members with her. On admission, you calculate her body mass index (BMI) to be 38, note that her respirations are shallow and rapid, and that she appears to be extremely anxious. Her medical history highlights that she has type 2 diabetes, which is managed with metformin, although she tells you that she has not been diligent about taking or recording her blood glucose level (BGL) regularly. She also informs you that a ‘couple of months ago' her GP prescribed tablets to treat her cholesterol and her blood pressure but she can't remember the names of them, and her son doesn't know them either. She has not taken any of these medications prior to her admission, her reason being that she was fasting. Her BP is 160/90 mmHg and her fasting BGL is found to be 12 mmol/L. You also identify that Mrs Afualo did not attend the preadmission clinic. She explains that she could not attend because her son was not available to drive her. Consequently, she has not had a preoperative chest X-ray (CXR) or any blood tests as per her surgeon's protocols. A check of Mrs Afualo's consent form in the presence of her son reveals it has not been signed and that she is somewhat confused about her intended surgery. What will be an ideal response?
