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.

Correct Answer: D

Rationale: The correct answer is D, 'Undermining.' Undermining occurs when the tissue under the wound edges erodes, indicating poor healing progress. This finding should be reported to the provider as it suggests delayed wound healing and may require intervention. Choice A, 'Eschar,' is a thick, hard, black/brown necrotic tissue that forms over a wound. While it indicates a non-healing wound, it is not as concerning as undermining. Choice B, 'Slough,' is a soft, moist, yellow/white tissue that is also a sign of necrosis. While the presence of slough indicates the need for wound cleaning and debridement, it is not as critical to report as undermining. Choice C, 'Granulation tissue,' is new tissue that forms during wound healing and is a positive sign. The presence of granulation tissue indicates that the wound is progressing through the healing stages and is not a finding that requires immediate reporting to the provider.

Correct Answer: C

Rationale: The correct answer is to use a sterile brush to clean the inner cannula. This action is crucial to prevent infection during tracheostomy care. Choice A is incorrect as clean technique is not adequate for tracheostomy care, sterile technique is required. Choice B is incorrect as tracheostomy ties should be replaced when soiled, not routinely every 24 hours. Choice D is incorrect as tracheostomy dressings should be changed more frequently to maintain cleanliness and prevent infection.

Correct Answer: C

Rationale: The correct answer is C. A respiratory rate of 10/min indicates respiratory depression, a serious adverse effect of morphine that should be reported immediately. Options A, B, and D are within normal limits and are not indicative of a potentially life-threatening complication associated with morphine therapy.

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.
