Correct Answer: A

Rationale: The correct answer is A: Clean the wound and apply a hydrocolloid dressing. This step is crucial in managing a pressure ulcer as it helps protect the ulcer from infection and promotes healing by creating a moist environment conducive to tissue repair. Choice B, debriding necrotic tissue and applying antibiotics, is more suitable for managing infected pressure ulcers but not as the initial step. Choice C, applying an alginate dressing and elevating the affected area, may be part of the management but is not the initial step. Choice D, using moisture-retentive dressings and repositioning frequently, is important for prevention but not the first step in managing an existing pressure ulcer.

Correct Answer: D

Rationale: The appropriate intervention for fluid overload involves a combination of measures, including restricting fluid intake to prevent further fluid accumulation, administering diuretics to help the body eliminate excess fluids, and closely monitoring vital signs to assess the patient's response to treatment. Therefore, all of the above options are correct. Restricting fluid intake alone may not be sufficient to address existing fluid overload without additional measures like diuretic therapy. Monitoring vital signs is essential to evaluate the effectiveness of the interventions and the patient's overall condition.

Correct Answer: A

Rationale: The correct answer is A because the LPN can care for stable clients with complex needs, such as managing an NGT set to continuous suction. Choices B, C, and D involve clients with more acute conditions that require a higher level of assessment and intervention, making them unsuitable for delegation to an LPN. Choice B requires prompt evaluation of the shortness of breath in a client with a recent femur fracture, which is beyond the LPN's scope. Choice C involves a head injury and unequal pupils, indicating the need for neurological assessment and close monitoring. Choice D relates to a critically low hemoglobin level and the need for blood transfusion, requiring careful monitoring and potential intervention beyond the LPN's role.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with chest pain because it helps relieve chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Assessing pain level, monitoring vital signs, and providing oxygen therapy are important interventions as well, but administering nitroglycerin takes precedence in addressing the immediate symptom of chest pain and potential cardiac ischemia.

Correct Answer: A

Rationale: In clients with oliguria, hypertension, and peripheral edema, protein should be restricted in the diet to reduce the workload on the kidneys. Excessive protein intake can lead to increased BUN levels, which can further stress the kidneys. Restricting protein can help prevent further kidney damage. Fats, carbohydrates, and magnesium do not directly impact kidney function in the same way as protein does, making them incorrect choices in this scenario.
