HESI Medical Surgical Practice Exam

1. A client is receiving continuous ambulatory peritoneal dialysis. Which of the following statements indicates the need for more teaching by the nurse?

A. I should take all my medications every morning.
B. The catheter should always remain in place.
C. The catheter should be flushed daily with sterile saline.
D. If I gain 2 pounds, I should skip dialysis that day.

Correct answer: D

Rationale: The correct answer is D. Gaining weight is a sign that the client may be retaining fluid, indicating a need for dialysis to remove excess fluid. Skipping dialysis based on weight gain can lead to fluid overload, electrolyte imbalances, and other serious complications. Choices A, B, and C are all correct statements regarding peritoneal dialysis care: taking medications as prescribed is essential for overall health, ensuring the catheter remains in place is crucial to prevent infection, and flushing the catheter with sterile saline daily helps maintain its patency and reduce the risk of infections.

2. 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.

3. A client with chronic renal failure is receiving epoetin alfa (Epogen). The nurse should assess the client for which of the following complications?

A. Hypertension.
B. Hypotension.
C. Hyperglycemia.
D. Edema.

Correct answer: A

Rationale: The correct answer is A: Hypertension. Epoetin alfa (Epogen) is known to increase blood pressure by stimulating red blood cell production. Monitoring for hypertension is crucial to prevent complications such as heart failure or stroke. Choices B, C, and D are incorrect because hypotension, hyperglycemia, and edema are not typically associated with epoetin alfa therapy in clients with chronic renal failure.

4. Which of the following is the most appropriate diet for a client during the acute phase of myocardial infarction?

A. Liquids as desired.
B. Small, easily digested meals.
C. Three regular meals per day.
D. Nothing by mouth.

Correct answer: B

Rationale: During the acute phase of myocardial infarction, it is recommended to provide small, easily digested meals for the client. This type of diet is better tolerated as it reduces the workload on the heart, allowing for easier digestion and absorption of nutrients. Choice A, 'Liquids as desired,' may not provide adequate nutrition and may not be well-balanced. Choice C, 'Three regular meals per day,' may be too heavy for the client's weakened condition. Choice D, 'Nothing by mouth,' is not appropriate as the client still requires essential nutrients for recovery.

5. After three days of persistent epigastric pain, a female client presents to the clinic. She has been taking oral antacids without relief. Her vital signs are heart rate 122 beats/minute, respirations 16 breaths/minute, oxygen saturation 96%, and blood pressure 116/70. The nurse obtains a 12-lead electrocardiogram (ECG). Which assessment finding is most critical?

A. Irregular pulse rhythm
B. Bile-colored emesis
C. ST elevation in three leads
D. Complaint of radiating jaw pain

Correct answer: C

Rationale: ST elevation in three leads is a critical finding that suggests myocardial infarction, requiring immediate attention. This finding indicates ischemia or injury to the heart muscle. Choices A, B, and D are not as critical in this scenario. Irregular pulse rhythm may be concerning but does not indicate an immediate life-threatening condition like myocardial infarction. Bile-colored emesis and complaint of radiating jaw pain are relevant but not as indicative of a myocardial infarction as ST elevation in three leads.
