Extract:
Question 1 of 5
The client is prescribed warfarin (Coumadin). Which food should the nurse instruct the client to limit?
Correct Answer: A
Rationale: Spinach is high in vitamin K, which antagonizes warfarin’s anticoagulant effect, potentially reducing its efficacy. Apples, chicken, and rice have negligible vitamin K.
Question 2 of 5
Which of the following side effects is associated with androgen therapy?
Correct Answer: C
Rationale: Androgen therapy promotes male secondary sexual characteristics leading to virilization (e.g. deepened voice facial hair). Gynecomastia is associated with estrogen and increased appetite or euphoria are not typical side effects of androgens.
Question 3 of 5
The nurse is preparing to collect a sputum specimen from the client suspected of having tuberculosis. What is the correct method for obtaining a sputum specimen?
Correct Answer: A, B, C, D
Rationale: Morning collection (
A) yieldsthough sputum is most concentrated. Three consecutive days (
B) ensure reliable tuberculosis diagnosis. Immediate transport (
C) prevents degradation. Mouth care (
D) maintains hygiene. Antiseptic rinse (E) may kill bacteria, invalidating the sample.
Question 4 of 5
A male client is scheduled to have angiography of his left leg. The nurse needs to include which of the following when preparing the client for this procedure?
Correct Answer: A
Rationale: Angiography, an invasive radiographic examination, involves the injection of a contrast solution (iodine) through a catheter that has been inserted into an artery. The client is kept on complete bed rest for 6-12 hours after the procedure. The extremity in which the catheter was inserted must be immobilized and kept straight during this time. The contrast dye, iodine, is nephrotoxic. The client must be instructed to drink a large quantity of fluids to assist the kidneys in excreting this contrast media. The major complication of this procedure is hemorrhage. Vital signs are assessed every 15 minutes initially for signs of bleeding.
Question 5 of 5
A client with a history of heart failure is receiving Spironolactone (Aldactone). The nurse should teach the client to:
Correct Answer: A
Rationale: Spironolactone, a potassium-sparing diuretic, risks hyperkalemia, so potassium-rich foods should be avoided. Sodium restriction, daytime dosing, and fluid management are secondary.
