HESI RN
HESI Nutrition Exam
1. 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.
2. After receiving change-of-shift report, which patient should the nurse assess first?
- A. Patient with a serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping
- B. Patient with a serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water
- C. Patient with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes
- D. Patient with a serum phosphorus level of 4.5 mg/dL who has multiple soft tissue calcium-phosphate precipitates
Correct answer: C
Rationale: The correct answer is patient C with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes. The low magnesium level and neuromuscular irritability suggest that the patient may be at risk for seizures, which are life-threatening. Assessing and addressing this patient's condition promptly is crucial to prevent complications. Patients A, B, and D have mild electrolyte disturbances or symptoms that require attention, but they are not at immediate risk for life-threatening complications like seizures, unlike patient C.
3. A client with severe dehydration is admitted to the hospital. Which assessment finding indicates that the client's condition is improving?
- A. The client reports feeling less thirsty
- B. Urine output increases to 40 mL/hour
- C. Heart rate decreases from 120 to 110 beats per minute
- D. Skin turgor returns to normal
Correct answer: B
Rationale: An increase in urine output is a reliable indicator that the client's hydration status is improving. This reflects adequate fluid replacement and improved kidney function. Choice A is subjective and may not always indicate improved hydration. Choice C, while a positive sign, may be influenced by other factors such as medications or pain. Choice D, skin turgor returning to normal, is a delayed indicator of hydration status and may take time to improve even after hydration is initiated.
4. A client with chronic heart failure is receiving furosemide (Lasix). Which assessment finding requires immediate intervention?
- A. Heart rate of 60 beats per minute
- B. Blood pressure of 110/70 mmHg
- C. Crackles in the lungs
- D. Peripheral edema
Correct answer: C
Rationale: In a client with chronic heart failure receiving furosemide, crackles in the lungs indicate pulmonary congestion, requiring immediate intervention. This finding suggests fluid accumulation in the lungs, impairing oxygen exchange and potentially leading to respiratory distress. Monitoring and managing pulmonary congestion promptly are crucial to prevent worsening heart failure and respiratory compromise. The other options, while important to assess in a client with heart failure, do not indicate an immediate need for intervention like crackles in the lungs do. A heart rate of 60 beats per minute may be within the normal range for some individuals, a blood pressure of 110/70 mmHg is relatively stable, and peripheral edema is a common manifestation of heart failure that should be monitored but does not require immediate intervention compared to pulmonary congestion.
5. Sildenafil (Viagra) is prescribed to treat a client with erectile dysfunction. A nurse reviews the client's medical record and would question the prescription if which of the following is noted in the client's history?
- A. Neuralgia
- B. Insomnia
- C. Use of nitroglycerin
- D. Use of multivitamins
Correct answer: C
Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin. Using nitroglycerin together with Viagra can lead to severe hypotension and cardiovascular collapse, making it unsafe to combine both medications.
