Extract:
Question 1 of 5
Which response by the nurse is most appropriate at this time?
Correct Answer: A
Rationale: Asking about concerns encourages the client to express fears, facilitating emotional support and reducing anxiety.
Question 2 of 5
A 72-year-old man had a total hip arthroplasty eight days ago. He suddenly develops tenderness in his left calf, a slight temperature elevation, and a positive Homan's sign. Which of the following will be included in the initial care of this man?
Correct Answer: C
Rationale: Placing the leg in a dependent position promotes venous return and reduces swelling in suspected deep vein thrombosis. Warm packs, massage, or range of motion may dislodge a clot, increasing embolism risk.
Question 3 of 5
Based on the client's complaint, the nurse would expect the pain to have which possible effect on the vital signs?

Rationale: Acute pain activates the sympathetic nervous system, increasing pulse rate due to stress response.
Question 4 of 5
When the client asks the nurse how cholesterol acts as a cardiac risk factor, what is the best explanation?

Rationale: High cholesterol contributes to atherosclerosis, where excess fat (lipids) deposits thicken and harden the arterial walls, narrowing the lumen and increasing cardiac risk.
Question 5 of 5
Digoxin (Lanoxin) and furosemide (Lasix) are ordered for a client who has congestive heart failure. Which of the following would the nurse also expect to be ordered for this client?
Correct Answer: A
Rationale: Furosemide, a diuretic, can cause potassium loss, leading to hypokalemia, which increases the risk of digoxin toxicity. Potassium supplements are often ordered to maintain normal levels.
