HESI Fundamentals Questions
Question 1 of 5
The client, who is newly diagnosed with arteriosclerosis and is obese, is being educated by the nurse on reducing the risk of a heart attack or stroke. Which health promotion brochure should the nurse provide to this client?
Correct Answer: C
Rationale: The most significant risk factor contributing to arteriosclerosis is excess dietary fat, particularly saturated fat and cholesterol. Therefore, the most crucial brochure for the nurse to provide to the client focuses on decreasing cholesterol levels through diet to help reduce the risk of heart attack or stroke.
Question 2 of 5
A client with a suspected kidney infection is admitted to the hospital for observation. Which action should the nurse implement to assess the client's kidney function?
Correct Answer: A
Rationale: Monitoring urine output is the most direct way to assess kidney function as it provides crucial information about the kidneys' ability to filter waste and produce urine. Changes in urine output can indicate potential issues with kidney function, such as decreased filtration or impaired excretion of waste products.
Question 3 of 5
The healthcare professional retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM 6 hours PRN for severe pain. How many mL should the healthcare professional administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth)
Correct Answer: A
Rationale: To calculate the mL to administer, divide the ordered dose (3 mg) by the concentration (4 mg/mL). 3 mg � 4 mg/mL = 0.75 mL. Rounding to the nearest tenth, the correct dose to administer is 0.8 mL.
Question 4 of 5
When caring for an older incontinent client at risk for infection, which intervention is best for the nurse to implement based on the nursing diagnosis of risk for infection?
Correct Answer: A
Rationale: The correct intervention for an older incontinent client at risk for infection is to maintain standard precautions. Standard precautions, which include proper handwashing, are essential in reducing the risk of infection transmission in vulnerable clients. Initiating contact isolation measures may not be necessary for all clients, and inserting an indwelling urinary catheter should be avoided unless medically necessary to prevent additional risks of infection. Instructing the client in the use of adult diapers is not an appropriate nursing intervention to prevent infection.
Question 5 of 5
The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
Correct Answer: B
Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.
