Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

Correct Answer: C

Rationale: An ethical dilemma involves a situation where there are conflicting values or principles that make it difficult to make a clear decision. In the given scenarios, option C best represents an ethical dilemma as the family has conflicting feelings about initiating enteral tube feedings for their terminally ill father. This situation presents a clash between different values and beliefs, making it challenging to reach a resolution. Options A, B, and D do not illustrate conflicting values or principles that characterize an ethical dilemma. Option A describes a nurse's impairment, which is a concern but not a direct ethical dilemma. Option B depicts a potential breach of client autonomy and restraint use, which is an ethical issue but not a true ethical dilemma. Option D involves a client's personal decision regarding a durable power of attorney form, which, although important, does not present conflicting values or principles that define an ethical dilemma.

Correct Answer: D

Rationale: In this scenario, the client has expressed that pain medication is not an option for managing pain. Offering alternative pain relief options like a back massage is appropriate because it respects the client's preferences and provides a non-pharmacological intervention to help alleviate pain. Choices A, B, and C are not as suitable: A may come across as dismissive of the client's decision, B may not be safe as herbal remedies can interact with medical treatments, and C focuses more on questioning the client's decision rather than providing immediate comfort.

Correct Answer: B

Rationale: Irritation of nasal mucosa is a crucial finding that the nurse should report to the provider as it suggests potential complications with NG tube placement, such as improper positioning or mucosal damage. High potassium levels (Choice A) can be concerning but are not directly related to NG tube placement issues. Normal sodium levels (Choice C) and loose stools (Choice D) are common occurrences in clients receiving tube feedings and are not typically indicative of immediate complications that require urgent reporting.

Correct Answer: A

Rationale: Collapsing the device when it is 1/2 to 2/3 full of air is the correct nursing action to ensure proper operation of a closed wound suction device (hemovac). This action maintains negative pressure, which is essential for proper suction and drainage of the wound. Emptying the device every 4 hours (Choice B) is not necessary as the focus should be on collapsing it appropriately. Replacing the device every 24 hours (Choice C) is not a standard practice unless indicated by the healthcare provider. Keeping the device above the level of the surgical site (Choice D) is not necessary for the device's proper operation; collapsing it to maintain negative pressure is the key action.
