HESI LPN
Practice HESI Fundamentals Exam
1. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 0.5 mL
- B. 1 mL
- C. 1.5 mL
- D. 2 mL
Correct answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg รท 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
2. The nurse is assessing a 9-year-old girl with a history of tuberculosis at age 6 years. She has been losing weight and has no appetite. The nurse suspects Addison disease based on which assessment findings?
- A. Arrested height and increased weight
- B. Thin, fragile skin and multiple bruises
- C. Hyperpigmentation and hypotension
- D. Blurred vision and enuresis
Correct answer: C
Rationale: The correct answer is C: Hyperpigmentation and hypotension. These findings are classic signs of Addison disease, caused by adrenal insufficiency. Hyperpigmentation results from increased ACTH stimulating melanin production, and hypotension occurs due to mineralocorticoid deficiency. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease. Thin, fragile skin and multiple bruises are seen in conditions like Cushing's syndrome, not Addison disease. Blurred vision and enuresis are not characteristic symptoms of Addison disease.
3. During a skin assessment, a client expresses concern about skin cancer. What findings should the nurse identify as a potential indication of a skin malignancy?
- A. A mole with an asymmetrical appearance.
- B. A mole with a regular border.
- C. A mole that is the same color throughout.
- D. A mole that is smaller than 6mm in diameter.
Correct answer: A
Rationale: The correct answer is A: A mole with an asymmetrical appearance. Asymmetry is a key characteristic of potential skin malignancy. An asymmetrical mole does not have a uniform shape when divided in half. This irregularity raises suspicion for skin cancer. Choices B, C, and D are incorrect. A mole with a regular border (B) is more likely to be benign. A mole that is the same color throughout (C) is also a feature commonly seen in benign moles. Additionally, a mole smaller than 6mm in diameter (D) is not necessarily indicative of malignancy, as some melanomas can be smaller or larger than this size.
4. Which statement about appendicitis is accurate and true?
- A. Appendicitis is more common among females than males.
- B. A high fiber diet is a risk factor associated with appendicitis.
- C. Left lower quadrant pain is suggestive of appendicitis.
- D. McBurney's point tenderness is suggestive of appendicitis.
Correct answer: D
Rationale: The correct answer is D: McBurney's point tenderness is suggestive of appendicitis. McBurney's point is located in the right lower abdomen and tenderness at this point is a classic sign of appendicitis. Choice A is incorrect as appendicitis is slightly more common in males than females. Choice B is incorrect as a high fiber diet is actually considered to be protective against appendicitis. Choice C is incorrect as appendicitis typically presents with pain in the right lower quadrant, not the left.
5. Is a low sperm count or lack of sperm the most common infertility problem in men?
- A. TRUE
- B. FALSE
- C. Rarely
- D. Never
Correct answer: A
Rationale: A low sperm count or lack of sperm is indeed one of the most common causes of infertility in men. Factors such as hormonal imbalances, genetic issues, reproductive anatomy problems, and lifestyle factors can also contribute to male infertility. Choice B is incorrect because a low sperm count is a prevalent issue among men facing infertility, making it a common problem. Choices C and D are incorrect as they do not accurately reflect the prevalence of low sperm count as a cause of infertility in men.
