HESI LPN
HESI Mental Health Practice Exam
1. An adolescent who attempted suicide with a drug overdose arrives in the emergency department with an empty 30-tablet bottle of acetaminophen (Tylenol). Which action should the nurse implement?
- A. Administer acetylcysteine (Mucomyst).
- B. Monitor cardiac rhythm for flat T waves.
- C. Check both serum AST and ALT levels.
- D. Prepare to administer Syrup of Ipecac.
Correct answer: A
Rationale: The correct action for the nurse to implement is to administer acetylcysteine (Mucomyst). Acetylcysteine is the antidote for acetaminophen overdose and should be administered promptly to prevent liver damage. Monitoring cardiac rhythm for flat T waves (Choice B) is not specific to acetaminophen overdose and is more related to cardiac conditions. Checking serum AST and ALT levels (Choice C) may be done later but is not the initial priority in this situation. Similarly, preparing to administer Syrup of Ipecac (Choice D) is not recommended anymore in cases of overdose as it can cause more harm.
2. The nurse determines that an adult client who is admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.4°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/68 mmHg. Which action should the nurse implement?
- A. Check the BP every five minutes for one hour.
- B. Raise the HOB 60 to 90 degrees.
- C. Ask the client to cough and deep breathe.
- D. Take the client’s temperature using another method.
Correct answer: D
Rationale: Taking the temperature using another method is essential in this situation to verify if the low reading is accurate and requires further intervention. The tympanic temperature of 94.6°F may be inaccurate due to various factors such as improper technique or environmental conditions. Checking the blood pressure every five minutes for one hour (Choice A) is not the priority in this case as the low blood pressure reading alone does not necessitate such frequent monitoring. Raising the head of the bed 60 to 90 degrees (Choice B) is not directly related to addressing the low temperature and blood pressure. Asking the client to cough and deep breathe (Choice C) is a general intervention that may not directly address the specific concern of the low temperature reading.
3. A client in the intensive care unit is being mechanically ventilated, has an indwelling urinary catheter in place, and is exhibiting signs of restlessness. Which action should the nurse take first?
- A. Review the heart rhythm on cardiac monitors
- B. Check urinary catheter for obstruction
- C. Auscultate bilateral breath sounds
- D. Give PRN dose of lorazepam (Ativan)
Correct answer: B
Rationale: When a client in the intensive care unit is mechanically ventilated, has an indwelling urinary catheter, and is restless, the priority action is to check the urinary catheter for obstruction. Restlessness in this context could be due to a blocked catheter causing discomfort or urinary retention, which needs immediate attention to prevent complications. Reviewing the heart rhythm on cardiac monitors can be important but is not the priority in this scenario. Auscultating bilateral breath sounds is also important in a ventilated client but addressing the potential immediate issue of a blocked catheter takes precedence. Giving a PRN dose of lorazepam should not be the first action without addressing the underlying cause of restlessness.
4. What instruction should the nurse include in the teaching plan for a client prescribed etanercept for rheumatoid arthritis?
- A. Rotate injection sites to prevent irritation.
- B. Take this medication with food to reduce gastrointestinal upset.
- C. Avoid sunlight exposure while on this medication.
- D. Notify the healthcare provider of any signs of infection.
Correct answer: A
Rationale: The correct instruction for a client prescribed etanercept is to rotate injection sites to prevent irritation and ensure proper absorption. Changing sites will help prevent skin irritation and ensure that the medication is absorbed effectively. This practice also reduces the risk of injection site reactions and discomfort. It is essential to follow this instruction to promote optimal medication delivery and minimize adverse effects. Choice B is incorrect because etanercept can be taken with or without food, and it is not specifically indicated to be taken with food to reduce gastrointestinal upset. Choice C is incorrect as there is no specific association between etanercept and sunlight exposure. Choice D is incorrect because while it is important to notify the healthcare provider of signs of infection, this is not the primary instruction related to the administration of etanercept.
5. The client who is 40 weeks gestation seems upset and tells the nurse that the physician told her she needs to have a nonstress test. The client asks why she needs the test. The nurse’s best response would be:
- A. This is a test to see if your stress level is affecting your baby’s growth and well-being.
- B. This is a test to see if your baby will be able to withstand the stress of labor.
- C. This is a test to assess your baby’s well-being now that you are due to deliver soon.
- D. This is a test to let us know if your baby needs to be delivered to avoid a bad outcome.
Correct answer: C
Rationale: The correct response is C because the nonstress test is specifically used to assess the baby's well-being close to the due date. It helps determine if the baby is receiving enough oxygen and nutrients in the womb. Choice A is incorrect as the test does not assess the mother's stress level but focuses on fetal well-being. Choice B is incorrect as the test does not predict the baby's ability to withstand labor. Choice D is incorrect because the test does not solely indicate if the baby needs to be delivered to avoid a bad outcome; rather, it assesses the current well-being of the baby.
