HESI Fundamentals Exam

Correct Answer: A

Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.

Correct Answer: A

Rationale: Pharyngeal diphtheria is primarily spread through droplet transmission, which occurs when an infected person coughs, sneezes, or talks, releasing respiratory droplets containing the bacteria. Therefore, the correct precaution for caring for a client with pharyngeal diphtheria is droplet precautions. Droplet precautions help prevent the transmission of respiratory pathogens over short distances via respiratory droplets. Contact precautions are used for diseases spread through direct or indirect contact with the patient or their environment. Airborne precautions are used for diseases that spread through small droplets suspended in the air. Standard precautions are basic infection prevention practices applying to all patient care.

Correct Answer: A

Rationale: Weight loss is a common finding in clients with hyperthyroidism due to increased metabolic activity. Hyperthyroidism leads to an overactive thyroid gland, which results in an increased metabolic rate and often leads to weight loss despite a normal or increased appetite. Cold intolerance (Choice B) is more commonly associated with hypothyroidism, where the body's processes slow down. Bradycardia (Choice C) is a slow heart rate, which is not typically seen in hyperthyroidism; rather, tachycardia or an increased heart rate is more common. Dry skin (Choice D) is also not a typical finding in hyperthyroidism, as the skin is more likely to be warm and moist due to increased metabolic activity.

Correct Answer: A

Rationale: The correct answer is A: High protein, high calorie. An immobilized patient with impaired skin integrity requires a diet high in protein and calories to repair injured tissue and rebuild depleted protein stores. This helps in promoting wound healing and preventing further breakdown of the skin. Choices B, C, and D are incorrect because while vitamins and minerals are essential for overall health, in this case, the priority is on providing sufficient protein and calories to support healing and recovery in an immobilized patient with impaired skin integrity.

Correct Answer: B

Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.
