HESI Fundamentals Practice Test
1. The client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which intervention should the nurse implement to ensure the client’s safety?
- A. Encourage the client to use oxygen continuously
- B. Monitor the client’s respiratory rate and effort
- C. Set the oxygen flow rate at 6 liters per minute
- D. Teach the client to avoid wearing wool blankets
Correct answer: B
Rationale: Monitoring the client’s respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.
2. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?
- A. Check for a blood return.
- B. Reposition the client's arm.
- C. Remove the IV site dressing.
- D. Flush the lock with saline.
Correct answer: B
Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.
3. A client with chronic renal failure 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: The correct answer is B: Hemoglobin and hematocrit. These are the primary laboratory tests to monitor the effectiveness of epoetin alfa (Epogen) in treating anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not directly related to the effects of this medication. Epoetin alfa stimulates the production of red blood cells, so monitoring hemoglobin and hematocrit levels helps assess the response to the treatment.
4. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?
- A. Superficial veins are more easily found in the feet and ankles.
- B. A decreased flow rate could lead to thrombosis formation.
- C. It is more challenging to move a cannulated extremity when using the leg or foot.
- D. Veins in the feet and ankles are located deep, making the procedure more painful.
Correct answer: B
Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
5. After insertion of the indwelling catheter, how should the nurse position the drainage container?
- A. With the drainage tubing taut to maintain maximum suction on the urinary bladder.
- B. Lower than the bladder to maintain a constant downward flow of urine from the bladder.
- C. At the head of the bed for easy and accurate measurement of urine.
- D. Beside the patient in their bed to avoid embarrassment.
Correct answer: B
Rationale: The correct position for the drainage container after inserting an indwelling catheter is to have it placed lower than the bladder. This positioning helps maintain a constant downward flow of urine from the bladder, preventing backflow and ensuring proper drainage. Choice A is incorrect because having the drainage tubing taut does not promote proper urine flow and may cause kinking. Choice C is incorrect as placing the container at the head of the bed does not affect drainage and is not necessary for accurate measurement. Choice D is incorrect as the positioning of the drainage container should prioritize proper drainage and care over potential embarrassment.
