HESI Fundamentals Practice Test
1. 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.
2. In the change-of-shift report, the nurse is told that a client has a Stage 2 pressure ulcer. Which ulcer appearance is most likely to be observed?
- A. Shallow open ulcer with a red-pink wound bed.
- B. A deep pocket of infection and necrotic tissues.
- C. An area of erythema that is painful to touch.
- D. Visible subcutaneous tissue with sloughing.
Correct answer: A
Rationale: A Stage 2 pressure ulcer typically presents as a shallow open ulcer with a red-pink wound bed. This appearance is characteristic of a Stage 2 pressure ulcer where there is partial thickness skin loss involving the epidermis and possibly the dermis. Choice B, a deep pocket of infection and necrotic tissues, is more indicative of a Stage 3 or Stage 4 pressure ulcer where the ulcer extends into deeper tissue layers. Choice C, an area of erythema that is painful to touch, is more commonly seen in early-stage pressure ulcers such as Stage 1. Choice D, visible subcutaneous tissue with sloughing, is characteristic of a more severe stage of pressure ulcer beyond Stage 2.
3. The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?
- A. 0.35 ml
- B. 0.40 ml
- C. 0.50 ml
- D. 0.45 ml
Correct answer: B
Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.
4. During the counseling session, you can also use the acronym, CLEAR. The letter E stands for:
- A. Encourage and assure the client of effective use of the method
- B. Explain how to use the method
- C. Tell the client about modern FP methods available, and discuss each in detail
- D. Explain all possible complications
Correct answer: B
Rationale: The correct answer is B: 'Explain how to use the method.' In the acronym CLEAR, the letter E specifically refers to explaining how to use the method, emphasizing the importance of providing clear instructions and guidance to the client. Choices A, C, and D are incorrect because they do not accurately represent what the letter E stands for in the given context. Encouraging and assuring the client, discussing modern FP methods in detail, and explaining possible complications are important aspects of counseling but do not align with the specific focus of 'Explain how to use the method,' as indicated by the acronym.
5. An adult male who fell from a roof and fractured his left femur is admitted for surgical stabilization after having a soft cast applied in the emergency department. Which assessment finding warrants immediate intervention by the nurse?
- A. Weak palpable distal pulses
- B. Pain at the fracture site
- C. Mild swelling of the leg
- D. Bruising around the fracture site
Correct answer: A
Rationale: In a patient with a fractured femur, weak palpable distal pulses can indicate compromised circulation to the lower extremity. This finding suggests a potential vascular compromise that requires immediate intervention to prevent further complications like compartment syndrome or ischemia. Pain at the fracture site, mild swelling of the leg, and bruising around the fracture site are expected following such an injury and surgical stabilization, and while they should be monitored, they do not require immediate intervention like addressing compromised circulation.
