Correct Answer: C

Rationale: The correct action to maintain a sterile field is to avoid reaching over it. This prevents contamination of the sterile environment by reducing the risk of unintentionally dropping microorganisms from non-sterile areas onto the sterile field. Opening sterile packages using the flap closest to your body first (choice A) is a good practice but not directly related to maintaining the sterile field. Donning sterile gloves before opening the sterile package (choice B) is crucial for maintaining sterility but not specific to maintaining the sterile field. Placing sterile items at least 2.5 cm (1 in) from the edge of the sterile field (choice D) is important to prevent accidental contamination, but it is not the primary action to maintain the sterile field.

Correct Answer: B

Rationale: Administering an intermittent enteral feeding through a gastrostomy tube requires flushing the tube with 10 mL of sterile water before feeding. This action helps ensure patency and prevents clogging. Choice A is incorrect because flushing after feeding does not address the need for pre-feeding tube flushing. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height of the feeding bag above the abdomen is typically regulated by healthcare facility policies and is not a universal standard.

Correct Answer: D

Rationale: Serum amylase levels are typically elevated in clients with acute pancreatitis as it is an enzyme released by the pancreas. Elevated serum sodium, calcium, or glucose levels are not typically associated with acute pancreatitis. Therefore, choices A, B, and C are incorrect.

Correct Answer: D

Rationale: The correct answer is D: Tachycardia. In clients with hyperthyroidism, tachycardia is a common finding due to the increased metabolic rate. Weight loss and heat intolerance are also expected due to the elevated metabolism. Choices A, B, and C (Weight gain, dry skin, cold intolerance) are not typical findings in hyperthyroidism, as the condition is associated with an overactive thyroid gland leading to an increase in metabolic functions.

Correct Answer: D

Rationale: In caring for a client 6 hours postoperative following a total hip arthroplasty, it is crucial to keep the leg abductor pillow in place while in bed. This intervention helps prevent hip dislocation by maintaining proper alignment and stability of the hip joint. Placing a wedge under the client's affected leg (Choice A) may not provide adequate support and could potentially compromise the surgical site. Keeping the client's hip flexed at a 90° angle (Choice B) or positioning the client with the legs extended and the hip externally rotated (Choice C) are not recommended post total hip arthroplasty as they may increase the risk of hip dislocation.
