Fundamentals HESI

Correct Answer: A

Rationale: The correct statement is: 'The temperature around the IV site is cooler.' Cooler temperature around the site is indicative of infiltration, where IV fluid leaks into the surrounding tissue, causing tissue swelling. The other options are incorrect: B) An increase in infusion rate is not a sign of infiltration; instead, it could indicate an issue with the infusion pump or the IV catheter. C) Redness around the IV site is more indicative of infection rather than infiltration. D) A damp IV dressing is more suggestive of a leak in the IV system, not infiltration.

Correct Answer: A

Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.

Correct Answer: A

Rationale: The correct answer is A: Capillary refill less than 3 seconds. This finding is considered normal and indicates good peripheral perfusion. Pitting edema (choice B) and pale nail beds (choice C) are abnormal findings that may suggest underlying health issues. Thick skin on the soles of the feet (choice D) is not an expected normal finding during a skin assessment and could be indicative of a callus or other skin condition.

Correct Answer: A

Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.

Correct Answer: A

Rationale: Placing the client in Trendelenburg's position is the appropriate action when providing chest physiotherapy for a client with left lower lobe atelectasis. This position helps mobilize secretions from the lower lobes of the lungs, aiding in their clearance. Trendelenburg's position promotes drainage from the affected area. Positioning the client in an upright sitting position (Choice B) would not facilitate the drainage of secretions from the affected lobe. Administering bronchodilators after the procedure (Choice C) is not directly related to chest physiotherapy and the treatment of atelectasis. Performing chest percussion and vibration while the client is lying flat (Choice D) may not effectively target the lower lobes where the atelectasis is located.
