HESI Fundamentals Practice Questions
1. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 400 mL/hr
- B. 200 mL/hr
- C. 300 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.
2. A nurse is planning care for a client who has hypernatremia. Which of the following actions should the nurse include in the plan of care?
- A. Infuse hypotonic IV fluids.
- B. Implement a fluid restriction.
- C. Increase sodium intake.
- D. Administer sodium polystyrene sulfonate.
Correct answer: A
Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.
3. A client has just returned from surgery with an indwelling urinary catheter in place. What is the most important action for the nurse to take to prevent infection?
- A. Change the catheter every 72 hours.
- B. Ensure the catheter tubing is free of kinks.
- C. Clean the perineal area with antiseptic solution daily.
- D. Irrigate the catheter with normal saline every shift.
Correct answer: B
Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. Kinks in the tubing can lead to urine retention or obstruction, increasing the risk of infection. Changing the catheter every 72 hours is not necessary if there are no signs of infection or other issues. Cleaning the perineal area with antiseptic solution daily is important for hygiene but not the most critical action to prevent infection related to the catheter. Irrigating the catheter with normal saline every shift is not a routine practice and may increase the risk of introducing pathogens into the urinary system.
4. After repositioning a client who reports shortness of breath, which of the following actions should the nurse take next?
- A. Observe the rate, depth, and character of the client's respirations.
- B. Take the client’s blood pressure.
- C. Assess the client's pulse.
- D. Offer supplemental oxygen.
Correct answer: A
Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.
5. A client with a history of heart failure is admitted with weight gain and peripheral edema. Which medication should the LPN/LVN anticipate being prescribed?
- A. Lisinopril (Zestril)
- B. Furosemide (Lasix)
- C. Metoprolol (Lopressor)
- D. Simvastatin (Zocor)
Correct answer: B
Rationale: Furosemide (Lasix) is the correct answer. In a client with heart failure experiencing weight gain and peripheral edema, the priority is to manage fluid overload. Furosemide is a loop diuretic commonly prescribed to reduce excess fluid in heart failure patients. Lisinopril (Zestril) is an ACE inhibitor used to treat hypertension and heart failure but does not directly address fluid overload. Metoprolol (Lopressor) is a beta-blocker that helps manage heart failure symptoms but does not primarily target fluid retention. Simvastatin (Zocor) is a statin used to lower cholesterol levels and is not indicated for managing fluid overload in heart failure.
