HESI Practice Test for Fundamentals

Correct Answer: B

Rationale: The correct action the nurse should take first when a patient needs to be mobilized after being in bed for several days is to dangle the patient at the bedside. Dangling at the bedside is the initial step to assess the patient's tolerance to sitting up and moving. It helps prevent orthostatic hypotension and allows the nurse to evaluate the patient's response to upright positioning before attempting further ambulation. Maintaining a narrow base of support (Choice A) is related to assisting with ambulation but is not the first step. Encouraging isometric exercises (Choice C) and suggesting a high-calcium diet (Choice D) are not immediate actions needed to initiate mobilization in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Temperature. A high fever is a significant indicator of infection or other serious conditions, making it the priority finding. Elevated temperature indicates an immediate concern for infection, which can quickly escalate and lead to severe complications if not addressed promptly. While heart rate, abdominal tenderness, and census overdue are important aspects to consider in the client's care, addressing the fever takes precedence due to its potential severity and implications for the client's health.

Correct Answer: D

Rationale: When using wrist restraints, it is important to allow room for two fingers to fit between the client's skin and the restraints. This practice ensures proper circulation and comfort for the client while still providing the necessary level of security. Choice A is incorrect because removing restraints every 4 hours may compromise the effectiveness of restraint use. Choice B is incorrect as restraints should not be attached to the side of the bed where they could cause harm or be tampered with by the client. Choice C is incorrect because allowing minimal movement may lead to discomfort and compromise proper circulation.

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 caring for a client with tuberculosis (TB), airborne precautions should be implemented. Tuberculosis is spread through the air via droplet nuclei, requiring the use of airborne precautions to prevent the transmission of the infection. Droplet precautions are used for diseases spread by large respiratory droplets, such as influenza or pertussis. Contact precautions are used for diseases that spread through direct contact, such as MRSA. Standard precautions are used for all clients to prevent the transmission of infections from blood, body fluids, non-intact skin, and mucous membranes.
