HESI Nutrition Exam
1. A nurse is reviewing a client's admission laboratory findings that indicate the client has hyponatremia. Which of the following laboratory findings should the nurse expect to be below the expected reference range?
- A. Magnesium
- B. Calcium
- C. Chloride
- D. Potassium
Correct answer: C
Rationale: The correct answer is C: Chloride. Chloride levels are typically low in cases of hyponatremia, as it often accompanies sodium loss. Magnesium (choice A) is not directly related to hyponatremia. Calcium (choice B) and Potassium (choice D) levels are usually not significantly affected by hyponatremia, making them less likely to be below the expected reference range in this scenario.
2. When a client is receiving external beam radiation to the mediastinum for treatment of bronchial cancer, which of the following should take priority in planning care?
- A. Esophagitis
- B. Leukopenia
- C. Fatigue
- D. Skin irritation
Correct answer: B
Rationale: Leukopenia should take priority in planning care for a client receiving external beam radiation to the mediastinum for bronchial cancer because it is a serious side effect that increases the risk of infection. Monitoring leukopenia is crucial to prevent complications. Esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, but leukopenia poses a higher risk of life-threatening infections, requiring immediate attention.
3. The nurse is monitoring a client who has just had a thyroidectomy. The client complains of tingling in the fingers and around the mouth. Which of these findings should the nurse assess first?
- A. Calcium level
- B. Chvostek's sign
- C. Trousseau's sign
- D. Serum potassium level
Correct answer: B
Rationale: The correct answer is B, Chvostek's sign. This is a classic sign of hypocalcemia, which can occur after a thyroidectomy due to injury or removal of the parathyroid glands. Hypocalcemia can lead to serious complications like tetany and laryngospasm, necessitating immediate attention. Assessing Chvostek's sign helps in early identification and management of hypocalcemia. Choices A, C, and D are not the priority in this situation. While assessing the calcium level is important for diagnosing hypocalcemia, the immediate concern is to identify clinical signs like Chvostek's sign, which indicate acute hypocalcemia. Trousseau's sign is also related to hypocalcemia but is not the most critical sign to assess first. Serum potassium level, although important for overall electrolyte balance, is not directly related to the client's current symptoms of tingling in the fingers and around the mouth.
4. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication:
- A. Can predispose to dysrhythmias
- B. May lead to oliguria
- C. May cause irritability and anxiety
- D. Sometimes alters consciousness
Correct answer: A
Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.
5. Which of these nursing diagnoses of 4 elderly clients would place 1 client at the greatest risk for falls?
- A. Sensory perceptual alterations related to decreased vision
- B. Alteration in mobility related to fatigue
- C. Impaired gas exchange related to retained secretions
- D. Altered patterns of urinary elimination related to nocturia
Correct answer: D
Rationale: The correct answer is D: Altered patterns of urinary elimination related to nocturia. Nocturia increases the risk of falls in elderly clients due to frequent nighttime trips to the bathroom. Choice A is incorrect because while decreased vision can contribute to falls, nocturia poses a more direct risk. Choice B is incorrect as fatigue may affect mobility but is not as directly linked to falls as nocturia. Choice C is incorrect as impaired gas exchange is not typically associated with an increased risk of falls.
