Question 1
A nurse is caring for a patient who has just been prescribed an anticoagulant. Which of the
following laboratory values should the nurse monitor closely for potential complications?
A. White blood cell count
B. Serum creatinine
C. International Normalized Ratio (INR)
D. Hemoglobin level
Correct Answer: C. International Normalized Ratio (INR)
Rationale: The International Normalized Ratio (INR) is used to monitor the therapeutic level of
anticoagulants like warfarin. If the INR is too high, it indicates that the blood is too thin and
there is an increased risk for bleeding. Monitoring this value helps ensure that the patient is
receiving the correct dose of anticoagulant therapy.
Question 2
Which of the following actions should the nurse take when administering a subcutaneous
,injection of insulin?
A. Massage the injection site to enhance absorption
B. Inject the needle at a 90-degree angle
C. Use the deltoid muscle as the primary site for injection
D. Draw up the insulin using a 5 mL syringe
Correct Answer: B. Inject the needle at a 90-degree angle
Rationale: When administering a subcutaneous injection, the needle should be inserted at a 90-
degree angle to ensure the medication is delivered into the fatty tissue. A 45-degree angle may be
used for thinner patients.
Question 3
A patient with chronic obstructive pulmonary disease (COPD) is experiencing difficulty
breathing. The nurse observes that the patient’s oxygen saturation is 85%. What is the priority
intervention?
A. Administer a bronchodilator
B. Place the patient in a high Fowler’s position
C. Increase the oxygen flow rate to 4 L/min
D. Encourage the patient to cough and deep breathe
Correct Answer: B. Place the patient in a high Fowler’s position
Rationale: Placing the patient in a high Fowler’s position helps to optimize chest expansion and
facilitates better oxygenation. While other interventions like administering a bronchodilator and
oxygen are important, positioning should be the first step.
,Question 4
A nurse is caring for a patient who has just undergone a mastectomy. The nurse notices that the
patient's arm on the affected side is swollen. What should the nurse do next?
A. Elevate the affected arm above the heart
B. Apply ice to the affected arm
C. Massage the arm to promote circulation
D. Place a compression bandage on the arm
Correct Answer: A. Elevate the affected arm above the heart
Rationale: Elevating the arm above the heart helps to reduce swelling by promoting venous
return. This is important to prevent complications like lymphedema after a mastectomy.
Question 5
Which of the following is a sign of dehydration in an older adult?
A. Increased urine output
B. Moist, warm skin
C. Decreased blood pressure upon standing
D. Weight gain
Correct Answer: C. Decreased blood pressure upon standing
Rationale: Orthostatic hypotension (a decrease in blood pressure upon standing) is a common
sign of dehydration in older adults, along with other symptoms like dry mouth, decreased skin
turgor, and dizziness.
, Question 6
A nurse is caring for a patient with a history of atrial fibrillation. The patient is prescribed
warfarin. Which laboratory test should the nurse monitor regularly?
A. Platelet count
B. Activated partial thromboplastin time (aPTT)
C. Prothrombin time (PT)
D. Hemoglobin and hematocrit
Correct Answer: C. Prothrombin time (PT)
Rationale: Warfarin therapy is monitored using the prothrombin time (PT) and International
Normalized Ratio (INR). These tests assess the clotting ability of the blood and guide appropriate
warfarin dosing.
Question 7
A patient with type 1 diabetes mellitus is experiencing nausea, vomiting, and a fruity odor to
their breath. What is the nurse’s priority action?
A. Administer insulin as prescribed
B. Encourage the patient to drink fluids
C. Obtain a blood glucose reading
D. Administer an antiemetic medication
Correct Answer: A. Administer insulin as prescribed
Rationale: The symptoms suggest diabetic ketoacidosis (DKA), a serious complication of
