HESI PN Exit Exam 2024
1. A client post-lobectomy is placed on mechanical ventilation. The nurse notices the client is fighting the ventilator. What should the nurse do first?
- A. Increase the sedation as prescribed.
- B. Manually ventilate the client using an ambu bag.
- C. Check the ventilator settings and alarms.
- D. Suction the client’s airway.
Correct answer: C
Rationale: The correct first action for the nurse to take when a client is fighting the ventilator is to check the ventilator settings and alarms. This step is crucial to ensure that the ventilator is functioning correctly and providing the necessary support to the client. Increasing sedation (Choice A) should only be considered after confirming that the ventilator settings are appropriate. While manually ventilating the client (Choice B) may be required in some cases, it is not the initial action to take. Suctioning the client's airway (Choice D) is not the priority in this situation, where the primary concern is addressing the client's struggle with the ventilator.
2. What is the primary function of hemoglobin in red blood cells?
- A. To transport oxygen from the lungs to body tissues
- B. To protect the body from infections
- C. To help in blood clotting
- D. To regulate body temperature
Correct answer: A
Rationale: The primary function of hemoglobin in red blood cells is to transport oxygen from the lungs to body tissues and return carbon dioxide from the tissues to the lungs. Hemoglobin binds to oxygen in the lungs and releases it in the body's tissues. Choice B is incorrect because hemoglobin is not involved in protecting the body from infections. Choice C is incorrect because blood clotting is mainly facilitated by platelets and clotting factors, not hemoglobin. Choice D is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not by hemoglobin.
3. The client with schizophrenia who continues to repeat the last words heard is exhibiting a sign of disturbed thought processes. Which nursing problem should the nurse document in the medical record?
- A. Altered sensory perception
- B. Impaired social interaction
- C. Risk for self-directed violence
- D. Disturbed thought processes
Correct answer: D
Rationale: The correct answer is D: Disturbed thought processes. Echolalia, the repetition of words, is a sign of disturbed thought processes commonly seen in clients with schizophrenia. It reflects a disorganization in thinking rather than a sensory perception issue (Choice A). Impaired social interaction (Choice B) refers to difficulties in relating to others, which is not the primary concern in echolalia. Risk for self-directed violence (Choice C) focuses on potential harm to self, which is separate from the repetitive behavior of echolalia.
4. A post-operative client is recovering from a total knee replacement and is prescribed patient-controlled analgesia (PCA). What is the primary advantage of PCA for managing post-operative pain?
- A. It allows for consistent pain control without overmedication.
- B. It eliminates the need for oral pain medication.
- C. It reduces the risk of opioid addiction.
- D. It requires less monitoring by nursing staff.
Correct answer: A
Rationale: The primary advantage of PCA for managing post-operative pain is that it allows the client to control the administration of pain medication, leading to consistent pain control without overmedication. Choice B is incorrect as PCA does not eliminate the need for oral pain medication; it supplements it. Choice C is incorrect because while PCA can help reduce opioid consumption, it does not directly reduce the risk of opioid addiction. Choice D is incorrect as PCA actually requires close monitoring by nursing staff to ensure proper use and prevent complications.
5. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?
- A. Parathyroid hormone
- B. Insulin
- C. Cortisol
- D. Thyroxine
Correct answer: A
Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.
