HESI Practice Test for Fundamentals

Correct Answer: C

Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.

Correct Answer: A

Rationale: The nurse's priority should be the client's temperature. A high temperature of 39.2 degrees C (102 degrees F) indicates a potential infection or inflammation that requires immediate attention. While heart rate and abdominal tenderness are important assessments, the temperature takes precedence as it signals a more urgent issue. Overdue menses, although significant, are not the priority in this scenario when compared to the possibility of an acute infection or inflammatory process.

Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.

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: 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.
