HESI LPN
HESI Practice Test for Fundamentals
1. A nurse observes an assistive personnel (AP) preparing to obtain blood pressure with a regular size cuff for a client who is obese. Which of the following explanations should the nurse give the AP?
- A. Using a cuff that is too small will result in an inaccurately high reading.
- B. Using a cuff that is too large will result in an inaccurately low reading.
- C. The regular size cuff is appropriate for all clients.
- D. You should use a cuff of any size as long as it fits.
Correct answer: A
Rationale: The correct answer is A: 'Using a cuff that is too small will result in an inaccurately high reading.' When obtaining blood pressure for an obese client, it is crucial to use a larger cuff to ensure an accurate reading. Choice B is incorrect because using a cuff that is too large for an obese client would actually result in an inaccurately low reading. Choice C is incorrect as a regular size cuff is not appropriate for obese clients due to their larger arm circumference. Choice D is incorrect because using a cuff of any size as long as it fits is not suitable for obtaining accurate blood pressure readings on an obese client.
2. A client with a terminal illness asks the nurse about what would happen if she arrived at the emergency department and had difficulty breathing, despite declining resuscitation in her living will. Which of the following responses should the nurse provide?
- A. We will determine who the durable power of attorney for health care form has designated.
- B. We will apply oxygen through a tube in your nose.
- C. We will ask if you have changed your mind.
- D. We will insert a breathing tube while we evaluate your condition.
Correct answer: B
Rationale: The correct response is to provide oxygen through a tube in the client's nose. Oxygen therapy can offer comfort and support breathing without being considered resuscitative. Therefore, this intervention aligns with the client's wish to decline resuscitation. Option A is not directly related to addressing the client's immediate breathing difficulty. Option C does not acknowledge the client's living will decision. Option D involves a more invasive procedure that may go against the client's wishes to decline resuscitation.
3. The healthcare provider is caring for a 17-month-old with acetaminophen poisoning. Which lab reports should the healthcare provider review first?
- A. Prothrombin time (PT) and partial thromboplastin time (PTT)
- B. Red blood cell and white blood cell counts
- C. Blood urea nitrogen and creatinine levels
- D. Liver enzymes (AST and ALT)
Correct answer: D
Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the toxic effects of the drug on the liver. Liver enzymes such as AST (aspartate aminotransferase) and ALT (alanine aminotransferase) are essential markers to assess liver function and damage. Monitoring these enzymes early is crucial to detect hepatotoxicity and guide further management. Prothrombin time and partial thromboplastin time are coagulation studies and are not the priority in acetaminophen poisoning. Red and white blood cell counts are not specific to assess liver damage in this context. Blood urea nitrogen and creatinine levels are primarily used to evaluate kidney function, which is not the primary concern in acetaminophen poisoning.
4. An assistive personnel (AP) is assisting a nurse with the care of a female client who has an indwelling urinary catheter. Which of the following actions by the AP indicates a need for further teaching?
- A. The AP hangs the collection bag below the level of the bladder.
- B. The AP performs hand hygiene before handling the catheter.
- C. The AP secures the catheter to the client’s leg with tape.
- D. The AP empties the collection bag when it is full.
Correct answer: A
Rationale: Hanging the collection bag below the level of the bladder is the correct technique for maintaining proper drainage and preventing backflow in a client with an indwelling urinary catheter. Therefore, choice A is the correct answer as it indicates a need for further teaching. Choices B, C, and D demonstrate appropriate actions in catheter care. Performing hand hygiene before handling the catheter helps prevent infection, securing the catheter to the client’s leg with tape prevents accidental dislodgement, and emptying the collection bag when it is full ensures that the catheter functions effectively.
5. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct answer: D
Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.
