A nurse is caring for a client who is participating in a research study for an experimental chemotherapy medication. After three treatments, the experimental medication is discontinued due to evidence of rapidly advancing kidney failure. The nurse should understand discontinuing this medication demonstrates which of the following ethical principles?

Correct Answer: D

Rationale: The correct answer is D: Nonmaleficence. Nonmaleficence is the ethical principle of doing no harm. In this scenario, discontinuing the experimental chemotherapy medication after evidence of rapidly advancing kidney failure is in line with this principle. Continuing the medication would harm the client further, so stopping it is the right course of action. Incorrect choices: A: Veracity - Veracity is the principle of truth-telling. Stopping the medication is not related to truth-telling. B: Autonomy - Autonomy is the principle of respecting the client's right to make their own decisions. Stopping the medication for the client's safety is not against their autonomy. C: Fidelity - Fidelity is the principle of keeping promises. Stopping the medication does not violate any promises made to the client.

Correct Answer: A

Rationale: The correct answer is A because standing up during the announcement can effectively signal to the team that something important is about to be shared. By changing position from sitting to standing, the nurse can capture the attention of the group and signal a shift in focus. This nonverbal cue can help to emphasize the importance of the announcement and create a sense of anticipation among the team members. Choices B, C, and D are incorrect because they do not effectively enhance the importance of the announcement. Crossing arms over the chest (B) can convey defensiveness or closed-off body language, which may not be conducive to fostering a positive reception to the message. Staring at individuals (C) can come across as aggressive or confrontational, potentially causing discomfort or resistance among the team. Leaning over the back of a chair (D) may appear casual or lack the gravitas needed to convey the significance of the announcement.

Correct Answer: B

Rationale: The correct answer is B. Glyburide is not recommended during breastfeeding as it can pass into breast milk and potentially affect the baby's blood sugar levels. This could be harmful to the infant. Choice A is unrelated to glyburide use. Choice C, getting a flu shot, is not a contraindication for taking glyburide. Choice D, being allergic to shellfish, does not directly impact the use of glyburide for diabetes.

Correct Answer: A

Rationale: Correct Answer: A Rationale: - The nurse should not separate the client's labia with her dominant hand as it increases the risk of contaminating the sterile field. - Choice B is correct as lubricating the catheter helps with insertion. - Choice C is correct as providing perineal care ensures cleanliness. - Choice D is correct as applying a sterile drape maintains a sterile field. Summary: Choice A is incorrect because it violates sterile technique. Choices B, C, and D are correct actions that promote proper catheter insertion.

Correct Answer: D

Rationale: The correct answer is D: Have gloves on while handling bedpans with feces. Rationale: Hepatitis A is primarily spread through fecal-oral route. Wearing gloves while handling bedpans with feces is crucial to prevent the transmission of the virus. Handwashing alone may not be sufficient to prevent cross-contamination. Summary of other choices: A: Placing signs does not directly prevent the spread of hepatitis A. B: Using a mask with a shield is not the most significant routine infection control measure for hepatitis A transmission. C: Wearing a gown for soiled linens does not address the primary mode of transmission for hepatitis A.
