HESI Practice Test for Fundamentals

Correct Answer: C

Rationale: When assessing the skin of an immobilized patient, it is essential to use a standardized tool like the Braden Scale. This tool helps in systematically evaluating the patient's risk of developing pressure ulcers. Assessing the skin every 4 hours (Choice A) may be too frequent or unnecessary unless there are specific concerns or orders. Limiting fluid intake (Choice B) is not directly related to skin assessment in an immobilized patient. Having special times for inspection to avoid interrupting routine care (Choice D) is not as crucial as using a standardized tool for consistent and comprehensive skin assessment.

Correct Answer: B

Rationale: Maintaining sterile technique when performing tracheostomy care is essential in preventing infections and complications. Option A is incorrect because povidone-iodine may be too harsh for cleaning around the stoma and can lead to skin irritation. Option C is incorrect because suctioning a tracheostomy should be done using sterile technique to minimize the risk of introducing pathogens. Option D is incorrect as tracheostomy ties need to be changed more frequently, usually every 1-2 days, to prevent skin breakdown and infection.

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: 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: A

Rationale: Lorazepam (Ativan) is the most appropriate preoperative medication for a client with severe anxiety. Lorazepam belongs to the benzodiazepine class and is commonly used to manage anxiety before surgical procedures due to its anxiolytic properties. Morphine sulfate and Meperidine (Demerol) are opioid analgesics, not typically indicated for preoperative anxiety. Promethazine (Phenergan) is an antihistamine used for nausea and vomiting, not anxiety management.
