A nurse in a pulmonology clinic is preparing a client for spirometry testing. Which question should the nurse ask the client during the preparation for this test?

"Are you allergic to shellfish?"

"Do you have any metal implants in your body?"

"Have you taken any bronchodilators today?"

"Are you claustrophobic?"

Answer and Explanation

The Correct Answer is C

. Shellfish allergies are related to potential reactions to iodinated contrast media used in imaging studies, such as CT scans, rather than to spirometry. Spirometry does not involve contrast media or shellfish, so this question is not pertinent for this test.
B.A Metal implants are typically a concern for imaging tests like MRI, which involve strong magnetic fields. Spirometry, however, does not involve any imaging or use of magnetic fields, so metal implants do not affect spirometry results. Thus, this question is not relevant for spirometry preparation.
C. This is a relevant question for spirometry testing. Bronchodilators are medications used to open the airways and improve breathing. They can affect spirometry results if taken shortly before the test. For accurate assessment, the nurse needs to know if the client has used any bronchodilators, as they might need to adjust the testing protocol or account for the medication's effects on lung function.
D. Spirometry does not typically involve enclosed spaces that would trigger claustrophobia, as it is a breathing test usually performed with the client sitting comfortably in an open space. Claustrophobia is more relevant to imaging studies like MRIs or CT scans, where the client might be in a confined space.

Correct Answer is B

Explanation

A. The immediate concern with abrupt cessation is more related to adrenal insufficiency rather than hyperglycemia. However, chronic use of prednisone can contribute to glucose intolerance and diabetes, but this is not the primary issue with sudden discontinuation.
B. Abrupt discontinuation of prednisone can lead to adrenal insufficiency because the body has become reliant on the medication to suppress inflammation and regulate various bodily functions. The adrenal glands may not immediately resume normal cortisol production, which can lead to symptoms of adrenal insufficiency, including hypotension.

C. Fluid retention is a common side effect of prednisone use. However, stopping prednisone suddenly does not typically cause fluid retention; rather, it can lead to other issues like adrenal insufficiency. Fluid retention is more related to the medication's use rather than its abrupt discontinuation.
D. Abruptly stopping high-dose prednisone, especially after long-term use, can be dangerous. The body may not immediately resume normal cortisol production, leading to symptoms of adrenal insufficiency, such as fatigue, weakness, and hypotension. It is crucial to taper off prednisone gradually under medical supervision to allow the adrenal glands time to recover and to avoid withdrawal symptoms.

A. Phacoemulsification B. Extracapsular cataract extraction C. Cochlear implant D. Surgical iridectomy

Correct Answer is D

Explanation

A. Phacoemulsification is a procedure used to remove cataracts from the eye. It involves using ultrasound waves to break up the cloudy lens (cataract) into small fragments, which are then suctioned out. While this procedure is relevant for cataract treatment, it does not address the acute management of angle-closure glaucoma.
B. Extracapsular cataract extraction is a surgical procedure to remove a cataract from the eye by making an incision and extracting the lens in one piece or in large segments. Like phacoemulsification, this procedure is focused on cataract removal and does not directly treat the underlying issue of acute angle-closure glaucoma.
C. A cochlear implant is a device used to provide a sense of sound to individuals with severe hearing loss or deafness. This procedure is unrelated to the treatment of eye conditions or intraocular pressure and therefore is not appropriate for managing primary angle-closure glaucoma.
D. Surgical iridectomy is a procedure specifically aimed at treating angle-closure glaucoma. It involves creating a small hole (iridectomy) in the peripheral iris to allow aqueous humor to flow from the posterior chamber of the eye to the anterior chamber, bypassing the obstructed drainage angle.
