HESI Medical Surgical Practice Quiz
1. A nurse reviews the laboratory findings of a client with a urinary tract infection. The laboratory report notes a “shift to the left” in the client’s white blood cell count. Which action should the nurse take?
- A. Request that the laboratory perform a differential analysis on the white blood cells.
- B. Notify the provider and start an intravenous line for parenteral antibiotics.
- C. Collaborate with the unlicensed assistive personnel (UAP) to strain the client’s urine for renal calculi.
- D. Assess the client for a potential allergic reaction and anaphylactic shock.
Correct answer: B
Rationale: A “shift to the left” in a white blood cell count indicates an increase in band cells, which is typically associated with urosepsis. In this scenario, the nurse should notify the provider and initiate IV antibiotics as a left shift is often seen in severe infections like urosepsis. Requesting a differential analysis on white blood cells would not be the immediate action needed in response to a left shift. Collaborating to strain urine for renal calculi is unrelated to the situation of a left shift in white blood cells due to urosepsis. Assessing for allergic reactions and anaphylactic shock is not the priority as a left shift is not indicative of an allergic response; it is associated with an increase in band cells, not eosinophils.
2. A 20-year-old female client calls the nurse to report a lump she found in her breast. Which response is the best for the nurse to provide?
- A. Check it again in one month, and if it is still there schedule an appointment.
- B. Most lumps are benign, but it is always best to come in for an examination.
- C. Try not to worry too much about it, because usually, most lumps are benign.
- D. If you are in your menstrual period it is not a good time to check for lumps.
Correct answer: B
Rationale: The nurse advising the client to come in provides the best response because it addresses the client's anxiety most effectively and encourages prompt and immediate action for a potential problem.
3. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:
- A. 85%
- B. 89%
- C. 95%
- D. 100%
Correct answer: C
Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.
4. A client with peripheral arterial disease (PAD) has cool and pale feet with diminished pulses. Which of the following interventions should the nurse implement?
- A. Keep the legs elevated above the level of the heart.
- B. Encourage the client to exercise daily.
- C. Apply warm compresses to the affected area.
- D. Apply ice packs to the affected area.
Correct answer: C
Rationale: In peripheral arterial disease (PAD), there is decreased blood flow to the extremities. Applying warm compresses helps dilate blood vessels, improve circulation, and relieve symptoms. Elevating the legs above the heart level may further compromise blood flow. Encouraging daily exercise is important in PAD management but may not be appropriate when the client has cool, pale feet with diminished pulses. Applying ice packs can worsen vasoconstriction and further reduce blood flow, exacerbating symptoms in PAD.
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?
- A. Evaluate the patient’s urine output.
- B. Contact the provider to order arterial blood gases.
- C. Request an order for an initial potassium bolus.
- D. Suggest a diet low in sodium and potassium.
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.
