HESI Fundamentals Practice Exam
1. After surgery, a patient has decreased cardiac output. What is a likely observation by the nurse?
- A. Decreased urine output
- B. Increased urine output
- C. Flushing of the skin
- D. Hyperventilation
Correct answer: A
Rationale: A decrease in cardiac output can lead to decreased blood flow to the kidneys, resulting in decreased urine output. The kidneys rely on adequate blood supply to filter waste and produce urine. Therefore, a decreased urine output is a common observation when cardiac output is reduced. Choices B, C, and D are incorrect. Increased urine output is not typically associated with decreased cardiac output; flushing of the skin is more related to vasodilation, and hyperventilation is not directly linked to decreased cardiac output.
2. After a needle stick occurs while removing the cap from a sterile needle, what action should the individual take?
- A. Complete an incident report.
- B. Select another sterile needle.
- C. Disinfect the needle with an alcohol swab.
- D. Notify the supervisor immediately.
Correct answer: B
Rationale: In the scenario described, the correct action after a needle stick injury is to discard the contaminated needle safely and choose a new sterile needle to continue the procedure. This step helps prevent potential transmission of infections and ensures the safety of both the individual and the patient. Disinfecting the needle with an alcohol swab is not adequate to address the risk of infection transmission. While completing an incident report and notifying the supervisor are important, the immediate action should be to replace the contaminated needle with a new sterile one to prevent any potential harm.
3. When suctioning a tracheostomy, which action is most appropriate for the nurse to take?
- A. Use a sterile tube each time and suction for 30 seconds.
- B. Use sterile technique and turn the suction off as the catheter is introduced.
- C. Use clean technique and suction for 10 seconds.
- D. Discard the catheter at the end of every shift.
Correct answer: B
Rationale: When suctioning a tracheostomy, it is crucial to use sterile technique to prevent infections. Turning off the suction as the catheter is introduced is important to avoid trauma and injury to the tracheal walls. This technique helps maintain the integrity of the tracheostomy site and ensures proper care for the patient.
4. A client with a diagnosis of anemia is receiving epoetin alfa (Epogen). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?
- A. White blood cell count.
- B. Hemoglobin and hematocrit.
- C. Platelet count.
- D. Blood urea nitrogen (BUN) and creatinine.
Correct answer: B
Rationale: To evaluate the effectiveness of epoetin alfa (Epogen) in treating anemia, the nurse should monitor hemoglobin and hematocrit levels. These values indicate the oxygen-carrying capacity of the blood, which directly relates to the treatment of anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not specific indicators of the effectiveness of epoetin alfa in treating anemia.
5. While changing a client’s post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given a positive MRSA result, what is the most important action for the nurse to take?
- A. Force oral fluids
- B. Request a nutrition consult
- C. Initiate contact precautions
- D. Limit visitors to immediate family only
Correct answer: C
Rationale: Initiating contact precautions is crucial in this situation to prevent the spread of MRSA infection. MRSA is a highly contagious bacterium that can spread through direct contact with an infected wound or by touching contaminated surfaces. By implementing contact precautions, the nurse can help contain the infection and protect other patients, healthcare workers, and visitors from being exposed to MRSA.
