HESI Medical Surgical Practice Quiz Questions
Question 1 of 5
A marathon runner comes into the clinic and states, 'I have not urinated very much in the last few days.' The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?
Correct Answer: A
Rationale: The priority action for the nurse is to give the client a bottle of water immediately. The athlete's symptoms of decreased urination, along with a heart rate of 110 beats/min and low blood pressure of 86/58 mm Hg, indicate mild dehydration. Rehydration should begin promptly to address the dehydration. Teaching the client to drink 2 to 3 liters of water daily is a good long-term strategy but not the immediate priority. Starting an intravenous line for fluids may be necessary if oral hydration is insufficient or if the degree of dehydration is severe. Performing an electrocardiogram is not indicated at this time as the priority is addressing the dehydration.
Question 2 of 5
The client with chronic kidney disease (CKD) is being taught about the necessary sodium restriction in the diet to prevent edema and hypertension. Which statement by the client indicates more teaching is needed?
Correct Answer: A
Rationale: Choice A, 'I am thrilled that I can continue to eat fast food,' indicates a lack of understanding as fast food is typically high in sodium, which is detrimental for individuals with CKD. The client should be advised to avoid fast food due to its high sodium content. Choices B, C, and D demonstrate a good understanding of the need for sodium restriction in the diet to prevent complications associated with CKD. Cutting out bacon, avoiding salt in cooking, and eliminating high-sodium snacks like potato chips are all positive steps towards managing CKD.
Question 3 of 5
A client who underwent surgery and experienced significant blood loss is being cared for by a nurse. Which findings by the nurse should prompt immediate action to prevent acute kidney injury? (Select all that apply.)
Correct Answer: C
Rationale: The nurse must monitor for signs of acute kidney injury in a postoperative client who had major blood loss. Low urine output, presence of sediment in the urine, and low blood pressure should raise concerns and be reported to the healthcare provider promptly. Postoperatively, assessing urine characteristics is crucial. Sediment, hematuria, and urine output less than 0.5 mL/kg/hour for 3 to 4 hours should be reported. While a urine output of 100 mL in 4 hours is low, it should be compared to the recommended 0.5 mL/kg/hour over a longer period. Perfusion to the kidneys is a priority, hence the importance of addressing low blood pressure. Amber, odorless urine is considered normal and does not indicate an immediate concern for acute kidney injury, unlike low urine output and presence of sediment.
Question 4 of 5
A patient's serum osmolality is 305 mOsm/kg. Which term describes this patient's body fluid osmolality?
Correct Answer: C
Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.
Question 5 of 5
The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient's electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?
Correct Answer: A
Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.
