HESI Practice Test for Fundamentals

Correct Answer: A

Rationale: It is important for the nurse to address their feelings of reluctance when dealing with a manipulative client by discussing them with an objective peer or supervisor. This action can provide valuable insight and support for managing the nurse-client relationship. Choice B should be avoided as limiting contacts with the client may not address the underlying issues and could potentially harm the therapeutic relationship. Choice C is confrontational and may escalate the situation rather than resolve it. Choice D, while important, should come after addressing the nurse's feelings and seeking support.

Correct Answer: C

Rationale: Corrected Rationale: Metabolic acidosis is a serious side effect of mafenide therapy that should be closely monitored. Mafenide can lead to metabolic acidosis due to its inhibition of carbonic anhydrase, resulting in the accumulation of carbonic acid. Curling ulcer (Choice A) is a stress-related mucosal lesion that occurs in the duodenum, primarily due to severe burns, not directly related to mafenide therapy. Renal shutdown (Choice B) is not a common side effect of mafenide therapy. Hemolysis of red blood cells (Choice D) is not a recognized side effect of mafenide cream application.

Correct Answer: C

Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.

Correct Answer: A

Rationale: The initial priority when admitting a client suspected of having pulmonary tuberculosis is to implement airborne precautions to prevent the spread of the disease. Airborne precautions include wearing a mask and placing the client in a negative pressure room. Obtaining a sputum culture is essential for confirming the diagnosis, but ensuring infection control measures come first to protect others. Administering antituberculosis medications is important but should be initiated after implementing necessary precautions. Recommending a screening test for close contacts is relevant but is a secondary concern compared to immediate infection control measures.

Correct Answer: C

Rationale: The correct answer is C. Checking the blood pressure of a 2-hour postoperative client is a task that can be safely delegated to an unlicensed assistive personnel (UAP) as it falls within their scope of practice. This task is routine and does not require specialized nursing knowledge or critical decision-making. Options A, B, and D involve tasks that require a higher level of training and critical thinking beyond the scope of a UAP. Taking a history, adjusting tube feeding rates, and monitoring a client receiving chemotherapy are responsibilities that should be performed by licensed healthcare providers who have the necessary skills and training.
