Which of the following statements reflects the principles of sterile technique?

Correct Answer: A

Rationale: The correct statement reflecting the principles of sterile technique is that sterile objects that come in contact with unsterile objects are considered contaminated. This principle is crucial in maintaining asepsis during medical procedures. Choice B is incorrect because items in a sterile package should only be used if they remain sterile; opening the package does not automatically contaminate the items. Choice C is incorrect as any part of a sterile field that hangs below the top of the table is considered unsterile. Choice D is incorrect as the edge of a sterile field and a border inward are typically considered unsterile to maintain the integrity of the sterile area.

Correct Answer: C

Rationale: The correct answer is C because documenting bilateral radial pulses being present, 2+, and hands warm to the touch is crucial when caring for a patient in restraints. This information helps in monitoring circulation and assessing the patient's well-being. Choices A, B, and D are incorrect because they do not provide essential information related to the patient's safety and well-being while in restraints.

Correct Answer: B

Rationale: In a disaster situation like a building collapse, the nurse should attend to the victim with a partial amputation of a leg who is bleeding profusely first. This victim is at immediate risk of severe blood loss, which can be life-threatening. It is crucial to address life-threatening injuries like severe bleeding before attending to other less urgent cases. The victim with the amputation requires immediate intervention to control bleeding and stabilize their condition. Victims who are already deceased or have less urgent injuries can be attended to after addressing the critical cases.

Correct Answer: A

Rationale: Using sterile gloves during catheter insertion is crucial to prevent infection. Sterile gloves help maintain asepsis during the procedure, reducing the risk of introducing microorganisms into the urinary tract. Cleaning the insertion site with alcohol, as mentioned in choice B, is important but not as critical as using sterile gloves. Choice C, inserting the catheter as quickly as possible, is not recommended as it can lead to errors and increase the risk of contamination. Choice D, using a smaller catheter size to minimize trauma, is not directly related to preventing infection but rather focuses on patient comfort and reducing tissue damage.

Correct Answer: B

Rationale: The correct answer is to contact the stoma nurse to assist the client with care. Stoma nurses are specially trained to provide guidance on stoma care, especially for clients with new ostomies. Instructing the client to care for the stoma independently (Choice A) may not be appropriate initially as they may need professional guidance. Delegating the care of the stoma to a nursing assistant (Choice C) is not recommended as specialized care is required. Waiting until the next shift (Choice D) is not ideal as stoma care should not be delayed.

Correct Answer: B

Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.

Correct Answer: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

Correct Answer: C

Rationale: When a surgical mask becomes moist, it loses its effectiveness as a barrier against microorganisms. Therefore, the perioperative nurse should apply a new mask. Choice A is incorrect because a moist mask should not be continued to be worn even if the nurse is comfortable. Choice B is not the best course of action as the mask should be changed immediately when it becomes moist. Choice D is also incorrect as waiting for the mask to air-dry is not recommended due to the loss of barrier effectiveness.

Correct Answer: B

Rationale: The correct answer is B because patients on fall precautions need continuous monitoring until discharge to prevent falls. While encouraging visitors during visiting hours (Choice A) is important for the patient's well-being, it is not related to fall precautions. Checking on the patient every shift (Choice C) is an essential nursing intervention, but keeping the patient on fall precautions is more specific to preventing falls. Raising all four side rails (Choice D) is not recommended as it can restrict the patient's mobility and is considered a restraint practice.
