RN NCLEX Practice Test Questions
Extract:
Question 1 of 5
The nurse is assessing breath sounds in a bronchovesicular client. She should expect that:
Correct Answer: D
Rationale: Inspiration is normally longer in vesicular areas. High-pitched sounds are normal in bronchial area. Muffled sounds are considered abnormal. Inspiration and expiration are equal normally in this area, and sounds are medium pitched.
Question 2 of 5
A young child has been placed in a spica cast. The chief concern of the nurse during the first few hours is:
Correct Answer: A
Rationale: Because the extremity may continue to swell and the cast could constrict circulation, the nurse should elevate the limb and observe for capillary refill, warmth, mobility of toes and circulation. Although muscle tone may diminish over time in the affected limb, this is not the immediate concern. The limb has been immobilized already by the cast, and therefore immobilization is not a concern. Heated fans and dryers are discouraged because the outside cast will dry quickly, yet the area beneath the cast remains wet and could cause burns.
Question 3 of 5
A client with gallstones and obstructive jaundice is experiencing severe itching. The physician has prescribed cholestyramine (Questran). The client asks, “How does this drug work?” What is the nurse’s best response?
Correct Answer: D
Rationale: Cholestyramine binds bile acids in the intestine, forming complexes excreted in stool, reducing circulating bile acids that cause itching. It doesn’t block histamine (
A), inhibit enzymes (
B), or reduce gallbladder bile (
C).
Question 4 of 5
The nurse discovers that a 78-year-old client who received hydralazine (Apresoline) 20 mg 45 minutes ago has a blood pressure of 70/40 mm Hg. The client has been on this dose of the medication for 3 years. Which of the following data is most likely significant in relation to the cause of the low blood pressure?
Correct Answer: B
Rationale: (A,
D) Decreased pulse volume and increased pulse rate are signs of an acute hypotensive episode. Inadequate fluid volume when taking vasodilators can result in a drop in blood pressure when vasodilation starts to physiologically occur as an action of the drug. A potassium level of 3.3 would not be associated with a significant drop in blood pressure.
Question 5 of 5
Which diet would the nurse expect to see ordered for a patient with nephrotic syndrome?
Correct Answer: B
Rationale: Nephrotic syndrome causes proteinuria, leading to hypoalbuminemia. A moderate protein diet (0.8–1 g/kg/day) helps replace lost protein without overloading the kidneys. Low carbohydrate, low calcium, or increased potassium diets are not specific to nephrotic syndrome.
