HESI Medical Surgical Practice Exam
1. What is the most common cause of peptic ulcers?
- A. Helicobacter pylori infection
- B. NSAID use
- C. Excessive alcohol consumption
- D. Stress
Correct answer: A
Rationale: Helicobacter pylori infection is the most common cause of peptic ulcers. This bacterium can weaken the protective mucous coating of the stomach and duodenum, allowing acid to get through to the sensitive lining beneath. NSAID use (Choice B) can also cause peptic ulcers by disrupting the stomach's mucosal barrier. Excessive alcohol consumption (Choice C) and stress (Choice D) can exacerbate and contribute to ulcer formation but are not the primary cause.
2. Which of the following is a characteristic symptom of multiple sclerosis (MS)?
- A. Muscle atrophy.
- B. Severe pain.
- C. Vision problems.
- D. Hearing loss.
Correct answer: C
Rationale: Vision problems are a characteristic symptom of multiple sclerosis (MS) due to demyelination of the optic nerve. This can lead to issues such as optic neuritis, blurred vision, double vision, or even total vision loss. Muscle atrophy (Choice A) is not a primary symptom of MS but can occur as a secondary effect of decreased mobility. Severe pain (Choice B) is not a typical symptom of MS, though some individuals may experience pain related to muscle spasms or other factors. Hearing loss (Choice D) is not commonly associated with MS unless there is an unrelated concurrent condition affecting the auditory system.
3. The nurse is preparing a female client for discharge after being treated for a urinary tract infection (UTI). Which statement by the client indicates a need for further teaching?
- A. I will use douches regularly to prevent future infections.
- B. I should drink at least 8 glasses of water a day.
- C. I should avoid tight-fitting clothing.
- D. I will wipe from front to back after using the toilet.
Correct answer: A
Rationale: The correct answer is A. Using douches is not recommended as it can disrupt the natural flora and increase the risk of infections. Choices B, C, and D are all correct statements that can help prevent UTIs. Drinking an adequate amount of water helps flush out bacteria, avoiding tight-fitting clothing promotes ventilation and reduces moisture, and wiping from front to back prevents the spread of bacteria from the anal region to the urethra.
4. A client with gastroesophageal reflux disease (GERD) is prescribed omeprazole. What is the primary purpose of this medication?
- A. Coat the lining of the stomach
- B. Neutralize stomach acid
- C. Promote gastric motility
- D. Reduce gastric acid secretion
Correct answer: D
Rationale: The correct answer is D: Reduce gastric acid secretion. Omeprazole is a proton pump inhibitor that works by reducing the production of gastric acid in the stomach. This helps in managing GERD by decreasing the acidity levels in the stomach. Choice A is incorrect because omeprazole does not coat the lining of the stomach. Choice B is incorrect as omeprazole does not neutralize stomach acid but rather reduces its production. Choice C is incorrect because omeprazole does not promote gastric motility; instead, it acts on acid secretion.
5. Meperidine hydrochloride (Demerol) is prescribed for a client with pain. Which of the following would the nurse monitor for as a side effect of this medication?
- A. Diarrhea
- B. Bradycardia
- C. Hypertension
- D. Urinary retention
Correct answer: D
Rationale: Meperidine hydrochloride (Demerol) is an opioid analgesic that can cause various side effects. Common side effects include respiratory depression, orthostatic hypotension, tachycardia, drowsiness, constipation, and urinary retention. Diarrhea is not a common side effect of Meperidine hydrochloride. Bradycardia and hypertension are not typically associated with this medication. Therefore, the nurse should monitor for urinary retention as a potential side effect of Meperidine hydrochloride.
