HESI Medical Surgical Exam Questions
Question 1 of 9
The client is preparing a morning dose of insulin, which includes 10 units of regular and 22 units of NPH. The nurse is verifying the client's preparation accuracy. What should the syringe read for the correct dose?
Correct Answer: C
Rationale: The correct answer is 32 units. To determine the correct dose, the nurse needs to add the 10 units of regular insulin to the 22 units of NPH, resulting in a total of 32 units. Therefore, the syringe should read 32 units. Choices A, B, and D are incorrect because they do not reflect the accurate total dose required for the morning insulin administration.
Question 2 of 9
A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 62, PaCO2 59, and HCO3. Which statement describes the most likely cause of the simultaneous increase in both the PaO2 and the PaCO2?
Correct Answer: B
Rationale: In patients with COPD, oxygen therapy can reduce the hypoxic drive, which is the primary stimulus for breathing in these individuals. By providing supplemental oxygen, the hypoxic drive is diminished, resulting in decreased respiratory effort. As a consequence, the PaO2 may increase due to the supplemental oxygen, but this can lead to a decrease in the respiratory drive and subsequent retention of carbon dioxide, causing an increase in PaCO2 levels. Option A is incorrect because rapid respirations would typically lower PaCO2 levels. Option C is incorrect as a pneumothorax would lead to impaired gas exchange and decreased PaO2 levels without necessarily affecting PaCO2 levels. Option D is incorrect as a pulmonary embolism would typically result in ventilation-perfusion mismatch and decreased PaO2 levels without directly impacting PaCO2 levels.
Question 3 of 9
After a session of hemodialysis, the nurse should monitor the client for which of the following complications of hemodialysis?
Correct Answer: B
Rationale: The correct answer is 'B: Hypotension.' Hypotension is a common complication of hemodialysis because fluid removal during the process can lead to a drop in blood pressure. The nurse should closely monitor the client for signs of hypotension such as dizziness, lightheadedness, or a decrease in blood pressure readings. Choice 'A: Hyperkalemia' is incorrect because hemodialysis actually helps lower potassium levels by removing excess potassium from the blood. Choice 'C: Infection' is incorrect as it is not a direct complication of hemodialysis but rather a risk associated with invasive procedures. Choice 'D: Fever' is incorrect as fever is not a typical immediate post-hemodialysis complication unless an underlying infection is present.
Question 4 of 9
Which of the following interventions is most appropriate for a patient with acute pancreatitis?
Correct Answer: B
Rationale: The most appropriate intervention for a patient with acute pancreatitis is administering IV fluids. IV fluid administration is crucial in managing acute pancreatitis as it helps maintain hydration, correct electrolyte imbalances, and prevent shock. Administering oral fluids (Choice A) may not be sufficient to address the fluid loss and maintain hydration in these patients. While analgesics (Choice C) are important for pain management in pancreatitis, addressing hydration and shock prevention takes precedence. Encouraging the patient to ambulate (Choice D) may be beneficial in some cases for preventing complications like deep vein thrombosis, but it is not the primary intervention needed in the acute phase of pancreatitis.
Question 5 of 9
A client with a history of type 1 diabetes Mellitus (DM) and asthma is readmitted to the unit for the third time in two months with a current fasting blood sugar (FBS) of 325mg/dl (18mmol/L SI). The client describes to the nurse not understanding why the blood glucose level continues to be out of control. Which interventions should the nurse implement?
Correct Answer: A
Rationale: The correct answer is to have the client describe a typical day at work, home, and social activities. By understanding the client's daily routine, the nurse can gain valuable insights into lifestyle factors that may be impacting blood glucose control. This information is essential for identifying potential triggers or patterns contributing to the elevated blood sugar levels. Option B, determining if the client is using a new insulin needle for each administration, focuses more on the technical aspect of insulin delivery and is not directly related to daily activities affecting blood glucose levels. Option C, evaluating the client's asthma medications that can elevate blood glucose, could be relevant but is not as directly linked to the client's lifestyle choices as option A. Option D, having the client demonstrate the technique for monitoring blood glucose levels, is important for assessing their skills but does not provide information on daily activities that may be influencing blood sugar levels.
Question 6 of 9
A client with diabetes mellitus who is taking NPH insulin (Humulin N) in the evening is most likely to become hypoglycemic shortly after midnight because this insulin peaks in 6 to 8 hours. What intervention should the nurse recommend to help prevent hypoglycemia while the client is sleeping?
Correct Answer: A
Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.
Question 7 of 9
A client is hospitalized with heart failure (HF). Which intervention should the nurse implement to improve ventilation and reduce venous return?
Correct Answer: B
Rationale: In clients with heart failure, placing them in high Fowler's position is beneficial as it helps reduce venous return and improve ventilation. This position aids in decreasing the workload on the heart by promoting better lung expansion and oxygenation. Passive range of motion exercises (Choice A) are not directly related to improving ventilation or reducing venous return. Administering oxygen via nasal cannula (Choice C) may help with oxygenation but does not directly address reducing venous return. Increasing the client's activity level (Choice D) may worsen heart failure symptoms by increasing the workload on the heart.
Question 8 of 9
In the staging process of Hodgkin's disease, what does Stage I indicate?
Correct Answer: A
Rationale: In the staging process of Hodgkin's disease, Stage I signifies the involvement of a single lymph node. This stage indicates localized disease with the disease being limited to a single lymph node or a group of adjacent nodes. Choices B, C, and D are incorrect because they describe more extensive involvement of lymph nodes, both sides of the diaphragm, or extralymphatic organs, which would correspond to higher stages in the staging system.
Question 9 of 9
A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:
Correct Answer: B
Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.
