HESI Fundamentals Study Guide

Correct Answer: D

Rationale: The nurse should prioritize assessing left lower extremity tenderness as it could indicate deep vein thrombosis, a serious condition that requires immediate attention. Musculoskeletal weakness, loss of appetite, and increased heart rate during physical activity are important but not as critical as a potential thrombotic event that could lead to life-threatening complications. Deep vein thrombosis is a common risk for individuals on prolonged bed rest due to reduced mobility and blood stasis.

Correct Answer: C

Rationale: Contact precautions are necessary when caring for a client with a wound infection to prevent the spread of infection. Contact precautions involve practices such as wearing gloves and gowns, and ensuring proper hand hygiene. Airborne precautions are for diseases transmitted by small droplet nuclei that can remain suspended in the air, like tuberculosis. Droplet precautions are for diseases transmitted through respiratory droplets larger than 5 microns, such as influenza. Standard precautions are used for all clients to prevent the spread of infection and include practices like hand hygiene, use of personal protective equipment, and safe injection practices. In this case, since the client has a wound infection, the nurse should focus on implementing contact precautions to reduce the risk of spreading the infection to themselves or others.

Correct Answer: A

Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.

Correct Answer: D

Rationale: The correct answer is to further assess the patient. 'ROM as needed' stands for Range of Motion, indicating that the patient should have their limbs moved to maintain joint flexibility and muscle strength. Before initiating any movements, it is crucial to assess the patient's current condition to determine their abilities and limitations. Restricting mobility (choice A) is not appropriate as it contradicts the purpose of ROM exercises. Realizing the patient is unable to move extremities (choice B) assumes without assessment and can lead to inappropriate care. Moving all the patient's extremities (choice C) without assessing the patient first can be harmful, as it may cause pain or injury if done incorrectly. Therefore, further assessment is necessary to provide safe and effective care.

Correct Answer: B

Rationale: For subcutaneous injections like heparin, a 25-27 gauge needle is recommended, making choice A incorrect. The abdomen is a commonly used site for heparin injection due to its consistent absorption and convenience, making choice B the correct answer. The Z-track technique is not necessary for subcutaneous injections, making choice C unnecessary. Observing for bleb formation is not a standard practice for confirming proper placement of subcutaneous heparin, making choice D incorrect. Therefore, the correct action is to select a site on the client's abdomen for the injection.
