HESI PN Exit Exam 2023

Correct Answer: D

Rationale: The correct answer is D: 'Avoid alcohol.' Alprazolam (Xanax) can have central nervous system depressant effects, which are exacerbated by alcohol. It is crucial to avoid alcohol while taking this medication to prevent severe sedation and respiratory depression. Monitoring heart rate (choice A) is not directly related to alprazolam administration. Monitoring temperature daily (choice B) is not a priority teaching point for a client prescribed alprazolam. Avoiding unprotected exposure to sunlight (choice C) is not specifically linked to the use of alprazolam.

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: B

Rationale: The correct answer is B: 'Did the child perform a finger stick?' Before administering insulin, it is crucial to check the child's blood glucose level to prevent hypoglycemia. Performing a finger stick blood glucose test provides essential information on the current blood sugar level. Choice A ('How much exercise did the child have today?') is not as critical as monitoring blood glucose levels directly. Choice C ('When did the child last urinate?') is not directly related to the immediate need for insulin administration. Choice D ('Has the child eaten recently?') is important but not as crucial as knowing the current blood glucose level.

Correct Answer: D

Rationale: The correct answer is D. Shakiness is a symptom of hypoglycemia, which is low blood sugar. Taking glucose can help raise blood sugar levels quickly in this situation. Fruity breath odor and excessive urination are signs of ketoacidosis, a complication of diabetes involving high levels of ketones in the blood. Blurred vision can be a symptom of high blood sugar, but it is not specific to hypoglycemia.

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.
