HESI Medical Surgical Specialty Exam Questions
Question 1 of 5
An adult female client has undergone a routine health screening in the clinic. Which of the following values indicates to the nurse who receives the report of the client's laboratory work that the client's hematocrit is normal?
Correct Answer: D
Rationale: The normal hematocrit for an adult female client ranges from 35% to 47%. A hematocrit value of 43% falls within this normal range, indicating normal levels of red blood cells. Choices A, B, and C are low hematocrit values and are considered below the normal range for adult females, signifying potential anemia or other health issues.
Question 2 of 5
A client with chronic obstructive pulmonary disease (COPD) who is beginning oxygen therapy asks the nurse why the flow rate cannot be increased to more than 2 L/min. The nurse responds that this would be harmful because it could:
Correct Answer: B
Rationale: Increasing the oxygen flow rate beyond 2 L/min for a client with COPD can decrease the client's oxygen-based respiratory drive. In clients with COPD, the natural respiratory drive is based on the level of oxygen instead of carbon dioxide, as seen in healthy individuals. Increasing the oxygen level independently can suppress the drive to breathe, leading to respiratory failure. Choices A, C, and D are incorrect because drying of nasal passages, increased risk of pneumonia due to drier air passages, and decreasing the carbon dioxide-based respiratory drive are not the primary concerns associated with increasing the oxygen flow rate in a client with COPD.
Question 3 of 5
A client with an oversecretion of renin has a health history reviewed by a nurse. Which disorder should the nurse correlate with this assessment finding?
Correct Answer: B
Rationale: Renin is secreted in response to low blood volume, blood pressure, or blood sodium levels. Excessive renin secretion can lead to persistent hypertension. Renin plays no role in Alzheimer's disease, diabetes mellitus, or viral hepatitis. Therefore, the correct correlation with oversecretion of renin is hypertension.
Question 4 of 5
A client was admitted for a myocardial infarction and cardiogenic shock 2 days ago. Which laboratory test result should a nurse expect to find?
Correct Answer: A
Rationale: In cardiogenic shock, decreased renal perfusion leads to an elevated BUN. Choice A is correct. Creatinine remains normal in cardiogenic shock as it signifies kidney damage, which has not occurred in this case. A low BUN indicates overhydration, malnutrition, or liver damage, which are not typically seen in cardiogenic shock. A low BUN/creatinine ratio is associated with fluid volume excess or acute renal tubular acidosis, not specifically indicative of cardiogenic shock.
Question 5 of 5
After a urography, a client is instructed by a nurse. Which instruction should the nurse include in this client's discharge teaching?
Correct Answer: C
Rationale: It is important for the client to increase fluid intake to aid in the rapid elimination of the potentially nephrotoxic dye used in urography. This instruction will help prevent any adverse effects related to the dye. Choices A, B, and D are incorrect because the dye used in urography is not radioactive, so there is no need to avoid direct contact with urine, urine dribbling is not a common post-procedure occurrence, and the dye should not cause the client's skin to change color.
