HESI Fundamentals Practice Exam
1. 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.
2. 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.
3. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?
- A. Administer regular insulin IV.
- B. Administer IV fluids at 250 ml/hr.
- C. Administer sodium bicarbonate IV push.
- D. Administer furosemide (Lasix) IV push.
Correct answer: A
Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.
4. A client has an elevated AST 24 hours following chest pain and shortness of breath. This is suggestive of which of the following?
- A. Gallbladder disease
- B. Liver disease
- C. Myocardial infarction
- D. Skeletal muscle injury
Correct answer: C
Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.
5. A client who has been on bed rest for several days is at risk for developing deep vein thrombosis (DVT). Which intervention should the nurse include in the client's plan of care?
- A. Encourage the client to ambulate as tolerated.
- B. Apply antiembolism stockings as prescribed.
- C. Elevate the client's legs on a pillow.
- D. Perform passive range-of-motion exercises daily.
Correct answer: B
Rationale: Applying antiembolism stockings as prescribed (B) is an effective intervention to prevent deep vein thrombosis (DVT) in a client on bed rest. While encouraging ambulation (A), elevating the legs (C), and performing passive range-of-motion exercises (D) are also beneficial, compression stockings are particularly effective in reducing the risk of DVT by promoting venous return and reducing stasis in the lower extremities.
