HESI Practice Test for Fundamentals

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: D

Rationale: The correct answer is 'Discipline.' In this scenario, discipline is exemplified by following a structured and comprehensive assessment process, as seen in the head-to-toe approach. Confidence (choice A) relates to self-assurance and belief in one's abilities, which is not the primary critical thinking demonstrated in this situation. Perseverance (choice B) is the persistence in achieving goals despite challenges, not directly related to the systematic assessment process. Integrity (choice C) pertains to honesty and ethical behavior, which are important traits but not the critical thinking skill exemplified by the structured assessment process shown in the head-to-toe approach.

Correct Answer: B

Rationale: When a patient is placed in the Sims' position, the nurse should observe pressure points on the ileum, clavicle, humerus, knees, and ankles. Choice A is incorrect as the chin and hips are not typically pressure points in the Sims' position. Choice C is incorrect as the shoulder and anterior iliac spine are not commonly observed pressure points in this position. Choice D is also incorrect as the occipital region of the head, coccyx, and heels are not pressure points commonly associated with the Sims' position.

Correct Answer: A

Rationale: The correct statement the nurse should include in the teaching is to 'Sit on the toilet 30 minutes after eating a meal.' This advice can help establish a regular bowel routine and improve bowel movement. Option B, 'Increase your fluid intake to help with bowel movements,' while important, is not specific to the time after eating and does not directly address the need for establishing a routine. Option C, 'Exercise regularly to improve bowel function,' is also important but does not address the timing of bowel movements. Option D, 'Consume more high-fiber foods to prevent constipation,' is beneficial for preventing constipation but does not address the timing aspect related to bowel movements.

Correct Answer: A

Rationale: When a client is receiving 100% oxygen via a partial rebreathing mask, there is a higher risk for oxygen toxicity due to the higher concentration of oxygen delivered. This client should be assessed most frequently for manifestations of oxygen toxicity. Choices B, C, and D are less likely to result in oxygen toxicity compared to 100% oxygen delivery via a partial rebreathing mask.
