Correct Answer: C

Rationale: Discussing approaches to chronic pain control is the most appropriate action in this situation as it helps the client manage the chronic pain associated with Heberden's nodes. Reviewing the client's dietary intake of high protein foods (Choice A) is not directly related to managing the pain caused by Heberden's nodes. Notifying the healthcare provider immediately (Choice B) may not be necessary unless there are urgent complications. Assessing the client's radial pulses and capillary refill time (Choice D) is important but not the priority in addressing the client's reported pain and the presence of Heberden's nodes.

Correct Answer: C

Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.

Correct Answer: B

Rationale: In a client with myasthenia gravis, difficulty swallowing is the most crucial symptom to report to the healthcare provider. This is because it can lead to aspiration, a severe complication in these clients. Diplopia (double vision) and weakness in the legs are common symptoms of myasthenia gravis but are not as immediately dangerous as difficulty swallowing. Fatigue is also a common symptom in myasthenia gravis but does not pose the same risk of aspiration as difficulty swallowing.

Correct Answer: A

Rationale: The correct answer is A: 'Shallow open ulcer with a red-pink wound bed.' Stage 2 pressure ulcers involve partial-thickness skin loss and typically appear as shallow open ulcers with a red-pink wound bed. Choice B describes a stage 1 ulcer, where the skin is intact but shows non-blanchable redness. Choice C describes a stage 3 ulcer, with full-thickness tissue loss exposing fat. Choice D is characteristic of a stage 4 ulcer, where there is full-thickness tissue loss exposing bone, tendon, or muscle. Therefore, option A best fits the description of a stage 2 pressure ulcer.

Correct Answer: A

Rationale: The correct answer is A: Neutrophil count. Neutrophil count helps assess for infection, which is indicated by the redness, tenderness, and swelling of the wound. Elevated neutrophil count is a common sign of bacterial infection. Hematocrit (choice B) measures the proportion of blood volume that is occupied by red blood cells and is not directly related to wound infection. Blood pH (choice C) and serum potassium and sodium (choice D) are important for assessing acid-base balance and electrolyte levels but are not the primary indicators of wound infection.
