HESI LPN
Adult Health Exam 1
1. The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?
- A. 15 mL
- B. 10 mL
- C. 20 mL
- D. 5 mL
Correct answer: A
Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.
2. A group of students is reviewing information about the endocrine system in infants and children. The students demonstrate understanding of the information when they state:
- A. Endocrine glands begin developing during gestation.
- B. Endocrine glands are fully functional at birth.
- C. Infants may have difficulty regulating glucose and electrolytes.
- D. A child’s endocrine system plays a significant role in growth and development.
Correct answer: C
Rationale: The correct answer is C. Infants may have difficulty regulating glucose and electrolytes due to their immature endocrine systems. This can lead to issues such as hypoglycemia and electrolyte imbalances. Choice A is incorrect because endocrine glands actually begin developing early in gestation, not just in the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth; they continue to mature and develop after birth. Choice D is incorrect as a child's endocrine system has a significant impact on growth and development through the secretion of hormones that regulate various processes in the body, but it does not specifically address the difficulty in regulating glucose and electrolytes seen in infants.
3. The nurse is caring for a client postoperatively following a thyroidectomy. Which assessment finding should be reported to the healthcare provider immediately?
- A. Hoarseness of the voice.
- B. Slight swelling at the incision site.
- C. Tingling around the mouth.
- D. Mild fever.
Correct answer: C
Rationale: Tingling around the mouth should be reported to the healthcare provider immediately as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common postoperatively due to surgical manipulation, slight swelling at the incision site is a normal response, and a mild fever can be expected after surgery. However, tingling around the mouth suggests a potential calcium imbalance, which requires prompt attention to prevent serious complications.
4. To accommodate a patient who is an Orthodox Jew, you would assure that her diet does not include which of the following?
- A. Any combination of meat and milk at the same meal
- B. Fish with scales
- C. Salmon
- D. Grape juice
Correct answer: A
Rationale: The correct answer is A. Orthodox Jewish dietary laws prohibit mixing meat and dairy in the same meal, so to accommodate an Orthodox Jew, you should ensure that their diet does not include any combination of meat and milk at the same meal. Choices B, C, and D are not prohibited in a kosher diet. Fish with scales, including salmon, are typically kosher, and grape juice is also permissible under kosher guidelines if certified. Therefore, options B, C, and D are acceptable in an Orthodox Jewish diet, while option A contradicts their dietary laws.
5. The nurse is planning care for a client with pneumococcal pneumonia. Which of the following would be most effective in removing respiratory secretions?
- A. Administration of cough suppressants
- B. Increasing oral fluid intake to 3000 cc per day
- C. Maintaining bed rest with bathroom privileges
- D. Performing chest physiotherapy twice a day
Correct answer: B
Rationale: Increasing oral fluid intake to 3000 cc per day is the most effective in removing respiratory secretions in a client with pneumococcal pneumonia. Adequate hydration helps thin secretions, making them easier to expectorate. Administration of cough suppressants (Choice A) may hinder the removal of secretions by suppressing the cough reflex. Maintaining bed rest with bathroom privileges (Choice C) is important but does not directly address the removal of respiratory secretions. Performing chest physiotherapy (Choice D) is beneficial for mobilizing secretions but may not be as effective as increasing fluid intake in thinning and facilitating the removal of secretions.
