Evolve HESI Medical Surgical Practice Exam
1. A client recovering from a urologic procedure is being assessed by a nurse. Which assessment finding indicates an obstruction of urine flow?
- A. Severe pain
- B. Overflow incontinence
- C. Hypotension
- D. Blood-tinged urine
Correct answer: B
Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.
2. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?
- A. 150 mL/hour
- B. 250 mL/hour
- C. 50 mL/hour
- D. 275 mL/hour
Correct answer: A
Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.
3. Which assessment data would provide the most accurate determination of proper placement of a nasogastric tube?
- A. Aspirating gastric contents to assure a pH value of 4 or less.
- B. Hearing air pass in the stomach after injecting air into the tubing.
- C. Examining a chest x-ray obtained after the tubing was inserted.
- D. Checking the remaining length of tubing to ensure that the correct length was inserted.
Correct answer: C
Rationale: The most accurate method to confirm the proper placement of a nasogastric tube is by examining a chest x-ray obtained after the tubing was inserted. This visual assessment allows healthcare providers to directly visualize the position of the tube in relation to anatomical landmarks, ensuring it is correctly placed in the stomach. Aspirating gastric contents or hearing air pass may provide some information but are not as definitive as a chest x-ray for confirming placement. Checking the remaining length of tubing is not a reliable method for determining proper placement as it does not indicate where the tip of the tube lies within the body.
4. During a home visit, the nurse finds that an elderly client has multiple expired medications. What should the nurse do first?
- A. instruct the client to dispose of the expired medications
- B. review the client's current medication regimen
- C. contact the client's healthcare provider
- D. educate the client on the dangers of taking expired medications
Correct answer: B
Rationale: The correct first action for the nurse to take when finding multiple expired medications in an elderly client's home is to review the client's current medication regimen. This step is crucial to identify any potential issues, ensure the client is taking the correct medications, and understand why the expired medications were not used. Instructing the client to dispose of the expired medications (Choice A) can come after understanding the current medication situation. Contacting the client's healthcare provider (Choice C) may be necessary but reviewing the medication regimen should be the initial step. Educating the client on the dangers of taking expired medications (Choice D) is important but should be done after addressing the immediate concern of reviewing the current medications.
5. The healthcare provider assesses a 2-year-old who is admitted for dehydration and finds that the peripheral IV rate by gravity has slowed, even though the venous access site is healthy. What should the healthcare provider do next?
- A. Apply a warm compress proximal to the site.
- B. Check for kinks in the tubing and raise the IV pole.
- C. Adjust the tape that stabilizes the needle.
- D. Flush with normal saline and recount the drop rate.
Correct answer: B
Rationale: In this scenario, the appropriate next step for the healthcare provider is to check for kinks in the tubing and raise the IV pole. These issues can commonly cause a slowed IV rate. Applying a warm compress (Choice A) may not address the underlying problem of kinked tubing or incorrect IV pole height. Adjusting the tape that stabilizes the needle (Choice C) is important for securement but is not the priority in this situation. Flushing with normal saline and recounting the drop rate (Choice D) should only be done after ruling out mechanical issues like kinks in the tubing.
