Question 1 of 5
The nurse is caring for a client with a new diagnosis of glaucoma. Which medication class should the nurse expect to administer?
Correct Answer: A
Rationale: Beta-blockers, such as timolol, reduce intraocular pressure in glaucoma by decreasing aqueous humor production, the primary treatment goal.
Question 2 of 5
Which type of anemia is diagnosed with a Schilling test?
Correct Answer: B
Rationale: The Schilling test is used to determine the cause of vitamin B12 deficiency, a potential precursor to pernicious anemia. This test involves the use of a small oral dose of radioactive B12 and a large nonradioactive intramuscular dose. A 24-hour urine specimen is then collected to measure the amount of radioactivity in the urine, and thus radioactive B12. This test is not helpful in diagnosing aplastic, megaloblastic, or iron-deficiency anemia.
Question 3 of 5
The nurse is involved in preoperative teaching with a client who will be undergoing a lung resection. The client is told that two chest tubes will be placed during surgery. The nurse explains that the purpose of the nurse is to:
Correct Answer: B, C
Rationale: Chest tubes are placed to remove air (pneumothorax) and fluid (hemothorax or pleural effusion) from the pleural space to restore negative pressure and lung expansion. Preventing clots or milking tubes is not their primary purpose.
Question 4 of 5
The nurse should inform a client taking carbamazepine (Tegretol) that it can affect other medications in which of the following ways?
Correct Answer: A
Rationale: Carbamazepine induces liver enzymes, reducing the effects of oral anticoagulants like warfarin by increasing their metabolism. It does not typically affect verapamil, other anticonvulsants, or contraceptives in the ways described.
