HESI LPN
HESI Practice Test for Fundamentals
1. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?
- A. Muscle weakness
- B. Joint pain
- C. Vision changes
- D. Skin rash
Correct answer: A
Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).
2. The client is being taught how to use a peak flow meter. The nurse explains that this device should be used to:
- A. Determine oxygen saturation
- B. Measure forced expiratory volume
- C. Monitor the atmosphere for the presence of allergens
- D. Provide metered doses for inhaled bronchodilator
Correct answer: B
Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.
3. When assessing bowel sounds, what action should a healthcare professional take?
- A. Listen to the bowel sounds before performing abdominal palpation
- B. Auscultate for 2 minutes to determine if bowel sounds are present
- C. Place the diaphragm of the stethoscope over each quadrant
- D. Ask the client to cough while auscultating
Correct answer: C
Rationale: When assessing bowel sounds, it is crucial to listen before performing any palpation as palpation can alter bowel sounds. The correct technique involves placing the diaphragm of the stethoscope over each quadrant of the abdomen to listen for bowel sounds. Auscultating for at least 5 minutes is recommended to accurately determine the presence or absence of bowel sounds. Asking the client to cough is not necessary for assessing bowel sounds and may not provide relevant information. Therefore, option C is the correct choice as it follows the appropriate procedure for assessing bowel sounds.
4. Which of the following findings contraindicate the use of haloperidol (Haldol) and warrant withholding the dose?
- A. Drowsiness, lethargy, and inactivity
- B. Dry mouth, nasal congestion, and blurred vision
- C. Rash, blood dyscrasias, severe depression
- D. Hyperglycemia, weight gain, and edema
Correct answer: C
Rationale: The correct answer is C: Rash, blood dyscrasias, and severe depression are serious side effects of haloperidol that necessitate withholding the dose and prompt further evaluation. Rash can indicate an allergic reaction, blood dyscrasias are serious blood disorders that can be life-threatening, and severe depression may worsen with haloperidol use. Choices A, B, and D are incorrect because drowsiness, lethargy, inactivity, dry mouth, nasal congestion, blurred vision, hyperglycemia, weight gain, and edema are common side effects of haloperidol that may not necessarily contraindicate its use but should be monitored and managed appropriately.
5. A nurse observes an assistive personnel (AP) preparing to obtain blood pressure with a regular size cuff for a client who is obese. Which of the following explanations should the nurse give the AP?
- A. Using a cuff that is too small will result in an inaccurately high reading.
- B. Using a cuff that is too large will result in an inaccurately low reading.
- C. The regular size cuff is appropriate for all clients.
- D. You should use a cuff of any size as long as it fits.
Correct answer: A
Rationale: The correct answer is A: 'Using a cuff that is too small will result in an inaccurately high reading.' When obtaining blood pressure for an obese client, it is crucial to use a larger cuff to ensure an accurate reading. Choice B is incorrect because using a cuff that is too large for an obese client would actually result in an inaccurately low reading. Choice C is incorrect as a regular size cuff is not appropriate for obese clients due to their larger arm circumference. Choice D is incorrect because using a cuff of any size as long as it fits is not suitable for obtaining accurate blood pressure readings on an obese client.
