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: C

Rationale: Applying lotion to the feet, avoiding between toes, is correct; over-the-counter treatments and soaking are not recommended.

Correct Answer: A

Rationale: The correct answer is A: Collaborating with providers to perform obesity screenings during routine office visits. This is a primary health care strategy as it focuses on prevention and early detection, which are key components of managing obesity. Screening during routine visits allows for timely identification of obesity and related health risks, enabling early intervention. Choices B, C, and D do not align with primary health care strategies for obesity. Ensuring availability of specialized beds, providing intraoperative training, and educating about postoperative complications are more focused on secondary and tertiary levels of care, rather than primary prevention and early detection.

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: B

Rationale: When a nurse asks a client to identify a number traced on the palm of the hand with their eyes closed, it assesses the client's ability to perceive touch sensations. This test specifically evaluates the tactile discrimination of the client. The other options do not test the client's ability to identify sensations accurately with eyes closed. Option A tests auditory perception, option C tests vibratory sense, and option D tests object recognition but not tactile discrimination, making them incorrect choices.
