HESI LPN
HESI Fundamental Practice Exam
1. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
2. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?
- A. Decreased calcium
- B. Elevated potassium
- C. Increased sodium
- D. Low hemoglobin
Correct answer: A
Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
3. When ethical dilemmas arise, what should newly licensed nurses expect and identify as an ethical dilemma?
- A. A nurse on a medical-surgical unit demonstrates signs of chemical impairment.
- B. A nurse overhears another nurse telling an older adult client that if he doesn’t stay in bed, she will have to apply restraints.
- C. A family has conflicting feelings about the initiation of enteral tube feedings for their father, who is terminally ill.
- D. A client who is terminally ill hesitates to name their partner on their durable power of attorney form.
Correct answer: C
Rationale: An ethical dilemma involves a situation where there are conflicting values or principles that make it difficult to make a clear decision. In the given scenarios, option C best represents an ethical dilemma as the family has conflicting feelings about initiating enteral tube feedings for their terminally ill father. This situation presents a clash between different values and beliefs, making it challenging to reach a resolution. Options A, B, and D do not illustrate conflicting values or principles that characterize an ethical dilemma. Option A describes a nurse's impairment, which is a concern but not a direct ethical dilemma. Option B depicts a potential breach of client autonomy and restraint use, which is an ethical issue but not a true ethical dilemma. Option D involves a client's personal decision regarding a durable power of attorney form, which, although important, does not present conflicting values or principles that define an ethical dilemma.
4. After abdominal surgery, a client has not urinated since the urinary catheter was removed 8 hours ago. What action should the LPN take first?
- A. Perform a bladder scan to assess for urinary retention.
- B. Encourage the client to drink fluids.
- C. Insert a straight catheter to drain the bladder.
- D. Administer a diuretic as prescribed.
Correct answer: A
Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.
5. A charge nurse is observing a newly licensed nurse perform tracheostomy care for a client. Which of the following actions by the newly licensed nurse requires intervention?
- A. Obtaining cotton balls for the tracheostomy care
- B. Using a sterile water bottle
- C. Checking the suction equipment
- D. Wearing a sterile gown
Correct answer: A
Rationale: The correct answer is A. Obtaining cotton balls for tracheostomy care is not recommended due to the risk of fiber contamination. Sterile gauze should be used instead. Choice B, using a sterile water bottle, is a correct and appropriate action for tracheostomy care to maintain cleanliness. Choice C, checking the suction equipment, is also a necessary step to ensure it is functioning properly for the procedure. Choice D, wearing a sterile gown, is a standard precaution to maintain a sterile environment during tracheostomy care.
