a) International Normalized Ratio (INR)

b) Activated partial thromboplastin time (aPTT)

c) Platelet count

d) Hemoglobin A1c

b) Activated partial thromboplastin time (aPTT)

Rationale: Heparin is monitored using aPTT to ensure therapeutic anticoagulation and prevent bleeding or clotting complications.

• A patient is to receive 1000 mL of normal saline over 8 hours. What is

the IV flow rate in mL/hr?

• 100 mL/hr 1 / 4

• 125 mL/hr
• 150 mL/hr
• 175 mL/hr
• 125 mL/hr

Rationale: 1000 mL ÷ 8 hours = 125 mL/hr.

• A nurse is caring for a patient with a new diagnosis of type 1 diabetes.

Which symptom should the nurse expect?

a) Weight gain

b) Polyuria

c) Bradycardia

d) Constipation

b) Polyuria

mg each. How many tablets should the nurse administer?

• 1 tablet
• 2 tablets
• 3 tablets
• 4 tablets
• 3 tablets

Rationale: 600 mg ÷ 200 mg/tablet = 3 tablets.

• A nurse is preparing to administer a blood transfusion. Which action

is most important before starting the transfusion?

a) Checking the patient’s temperature

b) Verifying the blood type with another nurse

c) Administering an antihistamine

mg/mL. How many mL should the nurse administer?

• 0.25 mL
• 0.5 mL

• 1.5 mL
• 0.25 mL

Rationale: 0.5 mg ÷ 2 mg/mL = 0.25 mL.

• A nurse is caring for a patient with a suspected myocardial infarction.

Which diagnostic test is most specific?

a) Chest X-ray

b) Troponin levels

c) Complete blood count

d) Blood glucose test

b) Troponin levels

Rationale: Troponin levels are highly specific for myocardial injury, indicating a myocardial infarction.

• A patient is to receive 500 mL of lactated Ringer’s over 4 hours. The

IV tubing has a drop factor of 15 gtt/mL. What is the flow rate in gtt/min?

• 30 gtt/min
• 31 gtt/min
• 32 gtt/min
• 33 gtt/min
• 31 gtt/min

Rationale: 500 mL ÷ 4 hours = 125 mL/hr. 125 mL/hr ÷ 60 min ≈ 2.083 mL/min. 2.083 mL/min × 15 gtt/mL ≈ 31 gtt/min.

• A nurse is teaching a patient with asthma about using a metered-dose

inhaler (MDI). Which instruction is most important?
