HESI Fundamental Practice Exam

Correct Answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

Correct Answer: D

Rationale: The correct answer is 'D: sunny side up (fried) eggs.' Fried eggs should be removed as they are not suitable for a mechanical soft diet due to their texture. The yolk of a fried egg is usually too hard and can be difficult for a client on a mechanical soft diet to chew and swallow. Poached or scrambled eggs are better alternatives for this diet as they are softer and easier to consume. Choices A, B, and C are all suitable for a mechanical soft diet as they are softer in texture and easier to chew and swallow.

Correct Answer: D

Rationale: When a client expresses feelings of hopelessness or worthlessness, it is crucial for the nurse to assess for suicidal ideation. Asking the client directly if she plans to harm herself is essential to determine the level of risk and ensure appropriate interventions are implemented. Recommending spiritual guidance (Choice A) may not address the immediate safety concerns related to suicidal ideation. Requesting additional support from the client's family (Choice B) is not as direct in addressing the client's safety. While stating that the client's response is a normal part of grief (Choice C) may provide validation, it does not address the potential risk of harm to the client.

Correct Answer: A

Rationale: The correct location to auscultate the aortic valve is the second intercostal space to the right of the sternum. This area corresponds to the aortic valve area where aortic valve sounds are best heard. Choices B, C, and D are incorrect for auscultating the aortic valve. The fifth intercostal space to the left of the sternum is where the mitral valve is best heard, the third intercostal space to the left of the sternum is where the pulmonic valve is best heard, and the fourth intercostal space at the midclavicular line is where the tricuspid valve is best auscultated.

Correct Answer: C

Rationale: The correct answer is C. Protecting others from exposure when transporting a client with MRSA is crucial in preventing the spread of infection. This statement demonstrates understanding of infection control measures. Stating that MRSA is usually resistant to vancomycin (choice B) is incorrect; vancomycin is often effective against MRSA. Obtaining a specimen for culture and sensitivity after the first dose of an antimicrobial (choice A) is unnecessary and not indicated. Discontinuing antimicrobial therapy when the client is no longer febrile (choice D) is incorrect because antimicrobial therapy should be completed as prescribed to prevent the development of resistant strains.
