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: 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 answer is A. In Judaism, it is customary for the body to be attended to by family or members of the community until burial. This practice is rooted in the belief of providing respect and care to the deceased individual. Choices B, C, and D are incorrect because they do not accurately reflect the cultural and religious traditions related to death for people who practice Islam, Buddhism, and Hinduism, respectively. People who practice Islam generally avoid cremation and opt for burial, Buddhists may have varying funeral service preferences, and Hindus often practice cremation without embalming the body.

Correct Answer: B

Rationale: Droplet precautions should be initiated for clients with infections that spread via droplet nuclei larger than 5 microns in diameter, such as influenza, rubella, meningococcal pneumonia, and streptococcal pharyngitis. In the case of influenza, the virus is primarily spread through respiratory droplets produced when an infected person coughs, sneezes, or talks. Airborne precautions are used for pathogens that remain infectious over long distances, typically smaller than 5 microns, like tuberculosis. Contact precautions are for diseases transmitted by direct or indirect contact, and protective environment precautions are for immunocompromised individuals to protect them from environmental pathogens.

Correct Answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).
