HESI RN
HESI Medical Surgical Specialty Exam
1. The nurse is caring for a patient who has recurrent urinary tract infections. The patient’s current infection is not responding to an antibiotic that has been used successfully several times in the past. The nurse understands that this is most likely due to
- A. acquired bacterial resistance.
- B. cross-resistance.
- C. inherent bacterial resistance.
- D. transferred resistance.
Correct answer: A
Rationale: The correct answer is A: acquired bacterial resistance. Acquired resistance happens when an organism has been exposed to the antibacterial drug, making it less effective over time. Cross-resistance (B) occurs when resistance to one drug leads to resistance to another. Inherent resistance (C) happens without prior exposure to the drug, meaning the bacteria are naturally resistant. Transferred resistance (D) involves the transfer of resistant genes from one organism to another, contributing to resistance development.
2. After a client delivered vaginally 2 days ago, what information should you share with her if she wants to resume using her diaphragm for birth control?
- A. The diaphragm is the most effective form of contraception.
- B. The diaphragm must be refitted after childbirth.
- C. Vaseline lubricant should be used when inserting the diaphragm.
- D. The diaphragm should be inserted 2 to 4 hours before intercourse.
Correct answer: B
Rationale: After childbirth, the diaphragm must be refitted to ensure a proper fit and effectiveness. Changes in the body post-delivery can affect the fit of the diaphragm, making it necessary to get refitted. Choice A is incorrect because while the diaphragm can be effective, it is not the most effective form of contraception. Choice C is incorrect because oil-based lubricants like Vaseline can damage latex diaphragms. Choice D is incorrect because the diaphragm should be inserted no more than 2 hours before intercourse, not 2 to 4 hours.
3. A client is scheduled to undergo computerized tomography (CT) with contrast for evaluation of an abdominal mass. The nurse should tell the client that:
- A. The test may be painful
- B. The test takes 2 to 3 hours
- C. Food and fluids are not allowed for 4 hours after the test
- D. Dye is injected and may cause a warm flushing sensation
Correct answer: D
Rationale: The correct answer is D. A contrast-aided CT scan involves the injection of dye to enhance the images obtained. The dye may cause a warm flushing sensation when injected, which is a common side effect. Choices A, B, and C are incorrect. CT with contrast is generally not a painful procedure, the duration of the test does not usually take 2 to 3 hours, and restrictions on food and fluids are typically before the test, not afterward.
4. A client who is admitted with a closed head injury after a fall has a blood alcohol level (BAL) of 0.28 (28%) and is difficult to arouse. Which intervention during the first 6 hours following admission should the nurse identify as the priority?
- A. Place in a side-lying position with head of bed elevated.
- B. Administer disulfiram (Antabuse) immediately
- C. Give lorazepam (Ativan) PRN for signs of withdrawal.
- D. Provide thiamine and folate supplements as prescribed.
Correct answer: A
Rationale: Maintain the patient's airway is the priority for a client who is intoxicated and obtunded.
5. A client is receiving external beam radiation to the mediastinum for treatment of bronchial cancer. Which of the following should take priority in planning care?
- A. Esophagitis
- B. Leukopenia
- C. Fatigue
- D. Skin irritation
Correct answer: B
Rationale: The correct answer is B: Leukopenia. Leukopenia, or a low white blood cell count, is a critical concern in clients undergoing radiation therapy due to the increased risk of infection. While esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, leukopenia poses a higher risk as it compromises the body's ability to fight infections effectively.
