HESI LPN
HESI Fundamental Practice Exam
1. A healthcare professional is preparing to insert an IV catheter into a client’s arm prior to initiating IV fluid therapy. Which of the following interventions should the healthcare professional implement to prevent infection?
- A. Thread the catheter up to the hub
- B. Use a sterile technique throughout the procedure
- C. Clean the insertion site with alcohol only
- D. Use gloves but not a mask during the procedure
Correct answer: B
Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.
2. A client with a history of seizures is prescribed phenytoin (Dilantin). Which statement should the LPN/LVN include when teaching the client about this medication?
- A. Do not take the medication with milk to avoid reduced absorption.
- B. Brush and floss your teeth regularly to prevent gum disease.
- C. Avoid taking antacids within 2 hours of the medication.
- D. Report any unusual bleeding or bruising to the healthcare provider.
Correct answer: C
Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.
3. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: A
Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.
4. A client is admitted with acute pyelonephritis. Which symptom should the nurse expect the client to report?
- A. Flank pain
- B. Pedal edema
- C. Hypotension
- D. Weight gain
Correct answer: A
Rationale: Flank pain is a classic symptom of acute pyelonephritis, which is a bacterial infection of the kidney. It occurs due to inflammation and irritation of the renal capsule, leading to pain in the flank region. Pedal edema (swelling in the feet and ankles) is more commonly associated with conditions like heart failure or kidney disease, not typically seen in acute pyelonephritis. Hypotension (low blood pressure) is a systemic symptom that may occur with severe infections but is not a specific hallmark of pyelonephritis. Weight gain is also not a typical symptom of acute pyelonephritis; instead, patients may experience weight loss due to decreased appetite and systemic effects of infection.
5. A nurse in a provider's office is obtaining the health and medication history of a client who has a respiratory infection. The client tells the nurse that she is not aware of any allergies, but that she did develop a rash the last time she was taking an antibiotic. Which of the following information should the nurse give the client?
- A. "Rashes are very common, especially if you have dry skin. Did it go away on its own?"
- B. "Virtually all medications have adverse effects. It sounds like this could have been an adverse effect of the antibiotic."
- C. "It's unlikely that your doctor will prescribe an antibiotic for what seems to be a minor viral infection, so we shouldn't be concerned about that rash."
- D. "We need to document the exact medication you were taking because you might be allergic to it."
Correct answer: D
Rationale: The correct answer is D. If a client reports developing a rash when taking a specific medication, even if they are not aware of any allergies, it is crucial to document this information. This is necessary to prevent future allergic reactions. Identifying the exact medication that caused the rash is essential as the client could have an allergy to it. Providing this information allows healthcare providers to avoid prescribing the same medication again, which could potentially lead to more severe allergic reactions or life-threatening situations. Choices A, B, and C are incorrect because they do not address the importance of documenting the specific medication that caused the adverse reaction or the potential risks of repeating the medication. Simply attributing the rash to common occurrences, adverse effects of medications in general, or assuming the rash is insignificant in the current context can overlook the critical aspect of identifying and avoiding allergens.
