Correct Answer: C

Rationale: Step-by-step rationale for choice C (Serum potassium level of 5.8 mEq/L) being the best to support a diagnosis of Addison's disease: 1. Addison's disease is characterized by adrenal insufficiency, leading to decreased aldosterone secretion. 2. Decreased aldosterone causes hyperkalemia due to impaired potassium excretion. 3. Elevated serum potassium levels above the normal range (3.5-5.0 mEq/L) are a classic finding in Addison's disease. 4. Therefore, a serum potassium level of 5.8 mEq/L strongly supports the diagnosis of Addison's disease. Summary: - Choice A (BUN level): BUN is not specific to Addison's disease and does not directly relate to adrenal function. - Choice B (Serum sodium level): Hyponatremia is a common finding in Addison's disease, but it is not as specific as hyperkalemia. - Choice D (Blood glucose level): Blood glucose

Correct Answer: C

Rationale: The correct order of priority for nursing actions for a new laryngectomee is: ii.Set up a visit from a well-adjusted laryngectomee, iii.Maintain a patent airway, iv.Control postoperative pain, i.Assist with ambulation. Setting up a visit from a well-adjusted laryngectomee comes first to provide emotional support and guidance. Maintaining a patent airway is crucial for breathing. Controlling postoperative pain is important for comfort. Assisting with ambulation is necessary but can be done after ensuring the other priorities are addressed. Other choices are incorrect because they do not prioritize emotional support, airway maintenance, and pain control before assisting with ambulation.

Correct Answer: C

Rationale: The correct answer is C, veins deep in the lower extremities, due to stasis and immobility in the legs causing blood to pool and predispose to thrombus formation. This is known as deep vein thrombosis (DVT). Veins deep in the upper extremities (A) are less commonly affected. The popliteal vein of the leg (B) is a common site for DVT, but it is not the most commonly affected. Veins connected to the heart (D) are arteries, not veins, and are not typically involved in thrombophlebitis.

Correct Answer: C

Rationale: The rule of nines is a method used to estimate the extent of burns on a patient's body. According to this rule, each major body part is assigned a percentage value that represents the total body surface area (TBSA). In this case, Mr. Kawasaki has second-degree burns on his right leg and arm (9% each) and left leg (9%) and third-degree burns on his left arm (9%). Adding these percentages together, we get a total of 36%, which corresponds to the extent of burn on Mr. Kawasaki's body. Choice A (18%) is incorrect because it only considers one arm and one leg, neglecting the other affected areas. Choice B (45%) is incorrect as it overestimates the extent of burns by including additional body parts not affected. Choice D (54%) is also incorrect as it includes more body parts than those actually burned. Therefore, the correct answer is C (36%) as it accurately reflects the distribution of burns based

Correct Answer: A

Rationale: Step 1: Involving the client in planning increases their understanding and ownership of the plan. Step 2: Understanding leads to better compliance with therapy recommendations. Step 3: Compliance improves outcomes and prevents complications. Step 4: Thus, choice A is correct. Choices B, C, and D lack direct links to client involvement in planning and compliance.
