Correct Answer: D

Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.

Correct Answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

Correct Answer: A

Rationale: The correct action for a healthcare professional planning to insert an IV for an older adult client is to place the client's arm in a dependent position. This positioning helps with vein prominence and facilitates easier IV insertion by enhancing blood flow and distending the veins. Placing the arm in a flexed position or elevating it to the level of the heart can impede vein visualization and make insertion more challenging. Using a tourniquet above the insertion site is a step in the IV insertion process but is not the initial action to take when preparing for the procedure.

Correct Answer: D

Rationale: The nurse should call the provider for clarification. In situations where there is difficulty reading an order, it is crucial to directly contact the healthcare provider to ensure the correct order is understood and followed. Leaving the order for the oncoming staff (Choice A) may lead to misunderstandings and errors. Contacting the charge nurse (Choice B) may cause delays as they may also need to contact the provider. Asking the pharmacy (Choice C) is not the most direct and immediate action in this scenario, as the provider is the one who can provide immediate clarification.

Correct Answer: A

Rationale: The correct answer is A: Knowledge. In this scenario, the healthcare professional is utilizing knowledge by gathering and applying information about the medication. Choice B, Experience, is not the best option as the focus is on accessing information about the medication rather than personal experience. Choice C, Intuition, refers to a gut feeling or instinct, which is not evident in the scenario. Choice D, Competence, relates more to overall ability and proficiency rather than the specific act of seeking information.
