HESI PN Exit Exam 2023

Correct Answer: B

Rationale: Errors in the calculation of medication dosages are a significant risk factor for medication errors. When dosage calculations are incorrect, it can lead to administering the wrong amount of medication, posing serious harm to the patient. Avoiding abbreviations for medications, barcoding medication orders, and utilizing unit dose dispensers are all strategies aimed at reducing medication errors by enhancing accuracy and safety. Therefore, choices A, C, and D are incorrect as they are practices that help decrease, rather than increase, the risk of medication errors.

Correct Answer: B

Rationale: In cases where elder abuse is suspected, the most critical action for the nurse to take is to report the findings to the supervisor for referral to adult protective services. This step is essential to protect the client from further harm and ensure their safety. Documenting the lacerations, as suggested in choice A, is important but not as urgent as ensuring immediate intervention by reporting the abuse. Asking the daughter for information, as in choice C, may not be effective if she is the abuser. Applying dressings, as in choice D, is a lower priority compared to taking action to address the suspected abuse.

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: C

Rationale: Moodiness is a typical emotional response during early adolescence. Hormonal changes and developmental challenges contribute to this behavior. While anger and combativeness can also be present during adolescence, they are not as consistently typical as moodiness. Cooperativeness, on the other hand, is a trait more commonly associated with later stages of development and maturity, rather than early adolescence.

Correct Answer: A

Rationale: Protecting the client's feet from injury is the most appropriate action for a client with cirrhosis experiencing peripheral neuropathy. Peripheral neuropathy can lead to a loss of sensation, making the client prone to unnoticed injuries. Applying a heating pad (Choice B) is contraindicated as it may cause burns or further damage to the affected area. Keeping the client's feet elevated (Choice C) is not directly related to managing peripheral neuropathy and may not provide significant benefit. Assessing the feet and legs for jaundice (Choice D) is important for monitoring liver function in clients with cirrhosis, but in this case, the priority is to prevent injury to the feet due to decreased sensation.
