RN NCLEX Practice Test Questions
Extract:
Question 1 of 5
The client is receiving a continuous heparin infusion. Which laboratory value should the nurse monitor most closely?
Correct Answer: C
Rationale: Heparin’s anticoagulant effect is monitored by aPTT, with a therapeutic range of 1.5–2.5 times the control value. Platelet count is monitored for heparin-induced thrombocytopenia, but PT and INR are for warfarin.
Question 2 of 5
Which of the following risk factors associated with breast cancer would a nurse consider most significant in a client's history?
Correct Answer: C
Rationale: Women who begin menarche late (after 13 years old) have a lower risk of developing breast cancer than women who have begun earlier. Average age for menarche is 12.5 years. Women who have never been pregnant have an increased risk for breast cancer, but a positive family history poses an even greater risk. A positive family history puts a woman at an increased risk of developing breast cancer. It is recommended that mammography screening begin 5 years before the age at which an immediate female relative was diagnosed with breast cancer. Early menopause decreases the risk of developing breast cancer.
Question 3 of 5
A patient with thrombocytopenia has a platelet count of 80,000. It will be most important to teach the client about:
Correct Answer: A
Rationale: Thrombocytopenia (low platelet count) increases bleeding risk. Teaching measures to reduce bleeding (e.g. avoiding trauma using soft toothbrushes) is critical. Fluid intake oxygenation and energy conservation are less directly related to the condition.
Question 4 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 5 of 5
A female client who has chronic obstructive pulmonary disease (COPD) has presented in the emergency department with cough productive of yellow sputum and increasing shortness of breath. On room air, her blood gases are as follows: pH 7.30 mm Hg, PCO2 60 mm Hg, PO2 55 mm Hg, HCO3 32 mEq/L. These arterial blood gases reflect:
Correct Answer: D
Rationale: Low pH, high PCO2, and normal HCO3 indicate uncompensated respiratory acidosis, reflecting acute exacerbation of COPD.
