HESI PN Exit Exam 2023

Correct Answer: B

Rationale: The correct statement about prelabor contractions (Braxton Hicks contractions) is that they are usually felt in the abdomen. They are irregular in nature and do not intensify with movement. Choice A is incorrect because prelabor contractions are irregular, not regular. Choice C is incorrect as prelabor contractions do not start in the back and radiate to the abdomen. Choice D is incorrect as prelabor contractions do not become more intense during walking.

Correct Answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

Correct Answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.

Correct Answer: D

Rationale: The correct action for the nurse to take when a client undergoing radiation treatment for breast cancer reports increasing fatigue is to reinforce the need for extra rest periods and plenty of sleep. Fatigue is a common side effect of radiation therapy, and adequate rest and sleep can help manage this symptom. Notifying the healthcare provider or charge nurse immediately (choice A) is not necessary for increasing fatigue, as it is expected during radiation therapy. Offering to reschedule the treatment for the following week (choice B) is not the best initial action for managing fatigue. Planning to monitor the client's vital signs every 30 minutes (choice C) is unnecessary and not directly related to managing fatigue caused by radiation therapy.

Correct Answer: C

Rationale: Pilocarpine eye drops are used to reduce intraocular pressure in glaucoma, not to anesthetize the eye. The PN should reteach the client about the purpose of the medication to ensure proper use and understanding, which is crucial for effective treatment. Choice A is incorrect because just documenting understanding without addressing the client's misconception is not enough. Choice B is incorrect as it provides incorrect information about the purpose of the eye drops and may lead to further misunderstanding. Choice D is incorrect as it provides inaccurate information stating that the drops provide pain relief, which is not their primary purpose.
