HESI LPN
Community Health HESI Practice Exam
1. Which of the following characteristics apply to 2 to 3-year-old children?
- A. Prefers to feed themselves
- B. Eats very small nutritious meals a day rather than 3 large meals
- C. Can speak in longer sentences
- D. Can use a toothbrush properly
Correct answer: B
Rationale: The correct answer is B. During the age of 2 to 3 years old, children tend to eat very small, nutritious meals throughout the day rather than having three large meals. This behavior is typical for this age group as their appetites fluctuate. Choices A, C, and D are incorrect because while children of this age may start to prefer feeding themselves and begin using a toothbrush with assistance, they typically do not speak in longer sentences at this stage.
2. A client with a diagnosis of hypertension is prescribed a thiazide diuretic. Which potential side effect should the nurse monitor for?
- A. Hyperkalemia
- B. Hypernatremia
- C. Hypokalemia
- D. Hypoglycemia
Correct answer: C
Rationale: The correct answer is C: 'Hypokalemia.' Thiazide diuretics commonly cause potassium loss, which can lead to hypokalemia. Monitoring potassium levels is essential when a client is taking thiazide diuretics to prevent complications such as cardiac dysrhythmias. Choices A, B, and D are incorrect. Hyperkalemia (choice A) is an elevated level of potassium, which is not typically associated with thiazide diuretics. Hypernatremia (choice B) is an elevated level of sodium, and hypoglycemia (choice D) is low blood sugar, neither of which are directly linked to thiazide diuretic use.
3. A client with a terminal illness is being cared for by a nurse. Which of the following findings indicates that the client's death is imminent?
- A. Cold extremities
- B. Increased appetite
- C. Elevated blood pressure
- D. Increased level of consciousness
Correct answer: A
Rationale: Cold extremities are a common sign observed in clients nearing death. This occurs due to decreased blood circulation as the body's systems begin to shut down. Cold extremities indicate poor perfusion and reduced function of vital organs. Increased appetite (Choice B) is not typically seen in clients approaching death; instead, a decreased appetite is more common. Elevated blood pressure (Choice C) is not a typical finding in clients nearing the end of life, as blood pressure tends to decrease. An increased level of consciousness (Choice D) is also not indicative of imminent death, as clients near death often experience decreased level of consciousness or become unresponsive.
4. The client is being instructed on how to collect a clean catch urine specimen. Which sequence is appropriate for teaching?
- A. Void a little, clean the meatus, then collect specimen
- B. Clean the meatus, begin voiding, then catch urine stream
- C. Clean the meatus, then urinate into container
- D. Void continuously and catch some of the urine
Correct answer: B
Rationale: The correct sequence for obtaining a clean catch urine specimen involves first cleaning the meatus to prevent contamination, then initiating voiding to catch the midstream urine. This method ensures that the sample is as uncontaminated as possible, making choice B the correct sequence. Option A is incorrect as cleaning the meatus should be done before voiding. Option C is incorrect as it does not involve catching a midstream urine sample. Option D is incorrect as it suggests catching urine throughout the entire voiding process, which may lead to contamination.
5. A nurse is assessing the oral cavity of a 6-month-old infant. The parent asks which teeth will erupt first. How should the nurse respond?
- A. Incisors
- B. Canines
- C. Upper molars
- D. Lower molars
Correct answer: A
Rationale: The correct answer is A: Incisors. In infants, incisors are usually the first teeth to erupt, typically around 6 months of age. These are the front teeth used for cutting food. Canines (Choice B), upper molars (Choice C), and lower molars (Choice D) typically erupt after the incisors. Canines are sharp teeth used for tearing food, while molars are flat teeth used for grinding food.
