A nurse is caring for a client who has a diagnosis of alcohol withdrawal. Which serum laboratory value validates the client's admitting diagnosis? A serum:
magnesium of 1.8 mEq/L
potassium 3.6 mEq/L
calcium of 8.7 mg/dL
phosphorus of 1.2 mg/dl.
The Correct Answer is A
Choice A rationale: A serum magnesium level of 1.8 mEq/L is lower than the normal range and can be associated with alcohol withdrawal.
Choice B rationale: Potassium level within the normal range is not specifically indicative of alcohol withdrawal.
Choice C rationale: Calcium level within the normal range is not specifically indicative of alcohol withdrawal.
Choice D rationale: Phosphorus level within the normal range is not specifically indicative of alcohol withdrawal.

Correct Answer is C
Explanation
Choice A rationale: Pursed-lip breathing is a compensatory mechanism to improve oxygenation and is not as severe an indication as cyanosis.
Choice B rationale: Clubbing of the nails is a chronic sign of oxygenation issues but may not be an acute and immediate indication of deterioration.
Choice C rationale: Cyanosis, the bluish discoloration of the skin and mucous membranes, is a serious indication of inadequate oxygenation.
Choice D rationale: Poor skin turgor is not a direct indicator of oxygenation status.
Correct Answer is B
Explanation
Choice A rationale: Promotion of oxygenation by enhancing air circulation around the wound is not the primary treatment for a "yellow" wound.
Choice B rationale: Removal of nonviable tissue followed by a moist wound dressing is the expected treatment for a wound with yellow color, indicating the presence of slough (nonviable tissue).
Choice C rationale: Use of barrier cream and a foam dressing may be indicated for other types of wounds but may not address the specific issue of nonviable tissue in a "yellow" wound.
Choice D rationale: No treatment is necessary is not appropriate for a wound with evidence of nonviable tissue.
