HESI Fundamentals Practice Exam
1. A client is admitted with a diagnosis of left-sided heart failure. Which assessment finding is most consistent with this diagnosis?
- A. Dependent edema.
- B. Ascites.
- C. Nocturia.
- D. Orthopnea.
Correct answer: D
Rationale: Orthopnea (D) is most consistent with left-sided heart failure. It is characterized by difficulty breathing when lying flat and is relieved by sitting up or standing. Dependent edema (A), ascites (B), and nocturia (C) are more commonly associated with right-sided heart failure. Dependent edema refers to swelling due to fluid accumulation, ascites is the accumulation of fluid in the peritoneal cavity, and nocturia is the excessive need to urinate during the night, all of which are more indicative of right-sided heart failure.
2. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Serum sodium level.
- B. Serum potassium level.
- C. Serum calcium level.
- D. Serum glucose level.
Correct answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.
3. A client's blood pressure reading is 156/94 mm Hg. Which action should the nurse take first?
- A. Inform the client that the blood pressure is high and that the reading needs to be verified by another nurse.
- B. Contact the healthcare provider to report the reading and obtain a prescription for an antihypertensive medication.
- C. Replace the cuff with a larger one to ensure a proper fit for the client and increase arm comfort.
- D. Compare the current reading with the client's previously documented blood pressure readings.
Correct answer: D
Rationale: The correct action for the nurse to take first in this situation is to compare the current blood pressure reading with the client's previously documented readings. This comparison will provide valuable information about what is normal for this specific client, helping to determine if the current reading represents a significant change or if it falls within the client's usual range. By reviewing the client's past readings, the nurse can assess trends, variations, and if the current reading is an isolated high value or part of a pattern, guiding appropriate decision-making. Informing the client about the high reading (Choice A) or contacting the healthcare provider for medication (Choice B) should come after assessing the client's history. Replacing the cuff (Choice C) is not necessary at this point and does not address the immediate need to compare the readings for appropriate intervention.
4. After an adult had an indwelling catheter removed, the nurse catheterizes them as ordered and obtains 200 cc of urine. What is the best interpretation of this finding?
- A. Is voiding normally.
- B. Has urinary retention.
- C. Has developed renal failure.
- D. Needs an indwelling catheter.
Correct answer: B
Rationale: The finding of obtaining 200 cc of urine after catheterization indicates urinary retention, as the bladder did not empty completely after the first void. This situation may require further assessment and intervention to address the issue of incomplete bladder emptying. Choice A is incorrect because voiding normally would indicate a larger amount of urine output. Choice C is incorrect as renal failure would typically present with other signs and symptoms. Choice D is incorrect as the presence of urinary retention does not necessarily mean the need for an indwelling catheter immediately.
5. The healthcare professional observes a UAP taking a client's blood pressure in the lower extremity. Which observation of this procedure requires the healthcare professional's intervention?
- A. The cuff wraps around the girth of the leg.
- B. The UAP auscultates the popliteal pulse with the cuff on the lower leg.
- C. The client is placed in a prone position.
- D. The systolic reading is 20 mm Hg higher than the blood pressure in the client's arm.
Correct answer: B
Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.
