HESI LPN
HESI Practice Test for Fundamentals
1. A healthcare provider is caring for several clients who are receiving oxygen therapy. Which client should the provider assess most frequently for manifestations of oxygen toxicity?
- A. 100% oxygen via partial rebreathing mask
- B. 2 liters per minute via nasal cannula
- C. 4 liters per minute via simple mask
- D. 6 liters per minute via face mask
Correct answer: A
Rationale: When a client is receiving 100% oxygen via a partial rebreathing mask, there is a higher risk for oxygen toxicity due to the higher concentration of oxygen delivered. This client should be assessed most frequently for manifestations of oxygen toxicity. Choices B, C, and D are less likely to result in oxygen toxicity compared to 100% oxygen delivery via a partial rebreathing mask.
2. The healthcare provider is caring for a client with a history of hypertension. Which assessment finding would be most concerning?
- A. Blood pressure of 150/90 mmHg
- B. Irregular heart rate
- C. Shortness of breath
- D. Headache
Correct answer: C
Rationale: Shortness of breath in a client with a history of hypertension is a critical assessment finding as it may indicate heart failure, pulmonary edema, or other severe complications. The development of shortness of breath suggests that the client's condition may be rapidly deteriorating and requires immediate medical attention. Elevated blood pressure (150/90 mmHg) is concerning but not as acute as the potential complications associated with shortness of breath. An irregular heart rate and headache can also be symptoms of hypertension, but in this scenario, shortness of breath poses a higher risk of severe cardiovascular or respiratory issues.
3. A client with lower extremity weakness is being taught a four-point crutch gait by a nurse. Which of the following instructions should the nurse include in the teaching?
- A. Bear weight on both legs.
- B. Move the crutches and the weak leg in unison.
- C. Advance the crutches and the strong leg simultaneously.
- D. Move the crutches forward, then move one leg at a time.
Correct answer: D
Rationale: The correct technique for a four-point crutch gait involves moving the crutches forward, then moving one leg at a time. This method provides stability and support by alternating movement between the crutches and legs. Choice A is incorrect because bearing weight on both legs simultaneously is not the correct method for a four-point gait. Choice B is incorrect as moving the crutches and weak leg together does not provide the required stability. Choice C is incorrect as advancing the crutches and strong leg together does not promote the alternating movement needed for a four-point gait.
4. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?
- A. Rectum
- B. Nasopharynx
- C. Intestinal tract
- D. Laryngopharynx
Correct answer: B
Rationale: Choanal atresia is a congenital condition characterized by the blockage of the nasal passages, specifically the choanae that connect the nasal cavity to the nasopharynx. The nurse should assess the nasopharynx to identify any obstruction, confirm the diagnosis, and assess the severity of the condition. Choices A, C, and D are incorrect as they do not pertain to choanal atresia. Choanal atresia specifically involves the nasal passages and nasopharynx, not the rectum, intestinal tract, or laryngopharynx.
5. The PN is caring for a client with schizophrenia who continues to repeat the last words heard. Which nursing problem should the PN document in the medical record?
- A. Altered thought processes
- B. Impaired social interaction
- C. Risk for self-directed violence
- D. Disturbed thought processes
Correct answer: D
Rationale: The correct answer is D: Disturbed thought processes. Echolalia, the repetition of heard words, is associated with disturbed thought processes, which are commonly seen in schizophrenia. Altered thought processes (Choice A) is a generic term and does not specifically address the behavior of repeating words. Impaired social interaction (Choice B) is not the primary concern when a client repeats the last words heard. Risk for self-directed violence (Choice C) is not directly related to the behavior of repeating words but focuses on the potential harm the client may cause to themselves.
