HESI Medical Surgical Practice Quiz

1. The patient is receiving sulfadiazine. The healthcare provider knows that this patient’s daily fluid intake should be at least which amount?

A. 1000 mL/day
B. 1200 mL/day
C. 2000 mL/day
D. 2400 mL/day

Correct answer: C

Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.

2. A patient is being treated for shock after a motor vehicle accident. The provider orders 6% dextran 75 to be given intravenously. The nurse should expect which outcome as the result of this infusion?

A. Decreased urine output
B. Improved blood oxygenation
C. Increased interstitial fluid
D. Stabilization of heart rate and blood pressure

Correct answer: D

Rationale: 6% Dextran 75 is a high molecular-weight colloidal solution used to treat shock from burns or trauma. Colloids like 6% dextran 75 are plasma expanders that help increase blood volume, leading to improved heart rate and blood pressure stabilization. The infusion of plasma expanders does not typically decrease urine output. It primarily aims to stabilize circulation rather than affect blood oxygenation or increase interstitial fluid levels.

3. A client with diabetes mellitus is scheduled to have blood drawn for a fasting blood glucose determination in the morning. What does the nurse tell the client is acceptable to consume on the morning of the test?

A. Water
B. Tea without sugar
C. Coffee without milk
D. Clear liquids like apple juice

Correct answer: A

Rationale: The correct answer is A: Water. A client scheduled for a fasting blood glucose test should only consume water after midnight to ensure accurate test results. Choosing options B, C, or D, which include tea, coffee, or clear liquids like apple juice, is incorrect as they may contain substances that can affect the blood glucose levels, leading to inaccurate test results.

4. Which of the following lab results is most indicative of dehydration?

A. Low sodium levels.
B. Elevated creatinine levels.
C. Low potassium levels.
D. High blood glucose levels.

Correct answer: B

Rationale: Elevated creatinine levels are indicative of dehydration because when the body is dehydrated, the kidneys concentrate urine to preserve fluid, leading to higher levels of creatinine. Low sodium levels (Choice A) can be seen in conditions like hyponatremia but are not specific to dehydration. Low potassium levels (Choice C) are more commonly associated with conditions like hypokalemia. High blood glucose levels (Choice D) are typically seen in diabetes and are not specific indicators of dehydration.

5. 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.
