Introduction
This comprehensive practice examination is designed to prepare nursing students for the BSN 266 HESI V2 exam. It
assesses foundational knowledge and clinical application across core nursing domains, including medical-surgical,
maternal-newborn, pediatric, and psychiatric-mental health nursing. The exam emphasizes critical thinking,
prioritization, and decision-making in real-world patient care scenarios. It includes questions that test your ability
to apply theoretical knowledge, adhere to legal and ethical standards, and safely manage medications. The
multiple-choice format, with one best answer per question, challenges you to integrate knowledge and skills
necessary for safe, effective nursing practice.
,SECTION ONE: QUESTIONS 1-100
1. A nurse is assessing a client who is 24 hours post-operative following a total hip arthroplasty. Which of the
following findings should the nurse report to the provider immediately?
A. Heart rate of 88/min
B. Pain level of 4 on a 0-10 scale
C. Oxygen saturation of 91% on room air
D. Blood pressure of 138/86 mmHg
🟢C
🔴 RATIONALE: An oxygen saturation of 91% on room air is below the expected reference range of 95-100%
and indicates potential respiratory compromise, which could be a sign of a pulmonary embolism, a serious
complication following hip surgery. This requires immediate intervention. The other vital signs are slightly
elevated or within acceptable post-operative limits.
2. A nurse is preparing to administer a scheduled dose of furosemide (Lasix) 40 mg IV push to a client with
heart failure. Which of the following laboratory values should the nurse check prior to administration?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum glucose
🟢B
🔴 RATIONALE: Furosemide is a loop diuretic that causes excretion of potassium in the urine, potentially
,leading to hypokalemia. It is essential to check the serum potassium level prior to administration to ensure it is
within a safe range (typically 3.5-5.0 mEq/L). The other labs are not the primary concern with this medication.
3. A client in the emergency department is exhibiting signs of anaphylaxis after receiving an antibiotic.
Which of the following actions should the nurse take first?
A. Administer epinephrine IM
B. Establish a patent airway
C. Apply a high-flow oxygen mask
D. Administer diphenhydramine IV
🟢B
🔴 RATIONALE: The priority in anaphylaxis is to secure a patent airway. Airway obstruction due to laryngeal
edema is the most immediate life-threatening risk. While administering epinephrine and oxygen are critical,
establishing and maintaining the airway is the first action in the ABC (Airway, Breathing, Circulation) framework.
4. A nurse is caring for a client with a nasogastric (NG) tube set to low intermittent suction. The nurse should
assess the client for which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hyponatremia
C. Hypokalemia
D. Hypercalcemia
🟢C
🔴 RATIONALE: NG tube suction removes gastric secretions, which are rich in potassium and hydrogen ions.
This loss can lead to metabolic alkalosis and hypokalemia. The client should be monitored for signs of low
potassium, such as muscle weakness, cardiac arrhythmias, and fatigue.
, 5. A nurse is providing discharge teaching to a client who has a new prescription for warfarin (Coumadin).
Which of the following statements by the client indicates an understanding of the teaching?
A. "I will increase my intake of leafy green vegetables."
B. "I will take ibuprofen for my headaches."
C. "I will report any bruising or bleeding to my doctor."
D. "I will take the medication at the same time every day with my other vitamins."
🟢C
🔴 RATIONALE: Warfarin is an anticoagulant that increases the risk of bleeding. The client must be instructed to
report any signs of bleeding, such as bruising, petechiae, or hematuria. Increasing leafy green vegetables (high
in Vitamin K) would decrease the drug's effectiveness. Ibuprofen can increase bleeding risk, and vitamins should
be discussed with the provider as they may interfere with warfarin therapy.
6. A postpartum nurse is assessing a client who delivered vaginally 2 hours ago. The nurse notes a large,
saturated perineal pad with bright red blood and a fundus that is boggy and displaced to the right. Which of
the following actions should the nurse take first?
A. Increase the IV infusion rate
B. Massage the fundus
C. Assist the client to the bathroom to void
D. Administer oxytocin as prescribed
🟢B
🔴 RATIONALE: A boggy, displaced fundus with heavy bleeding indicates uterine atony, the most common
cause of postpartum hemorrhage. The immediate nursing action is to massage the fundus to stimulate uterine
contraction. While other actions like administering oxytocin are important, massage is the first-line,
independent nursing intervention to control the bleeding.
