Correct Answer: B

Rationale: The correct answer is B: Ataxia. Ataxia, which refers to uncoordinated movements, is a common adverse effect of phenytoin, a medication used to manage seizure disorders. Bradycardia (Choice A) is not typically associated with phenytoin; instead, it may cause tachycardia (Choice C) as a side effect. Insomnia (Choice D) is not a common adverse effect of phenytoin.

Correct Answer: B

Rationale: The correct intervention for a client with nonblanchable erythema over the ischium is to teach the client to shift his weight every 15 minutes while sitting. This action helps relieve pressure on the affected area and prevents further skin breakdown. Placing the client upright on a donut-shaped cushion (Choice A) may not address the need for frequent weight shifts. Turning and repositioning the client every 3 hours (Choice C) is important for overall skin health but may not provide adequate relief for the specific area of nonblanchable erythema. Assessing pressure points every 24 hours (Choice D) is not frequent enough to prevent worsening of the skin condition in this case.

Correct Answer: C

Rationale: Obtaining arterial blood gases is a crucial nursing action when caring for a client with an arterial line. This procedure helps assess the client's oxygenation status and acid-base balance accurately. Leveling the transducer with the client's phlebotomy site (A) is important for accurate pressure measurements, but it is not the primary action in this scenario. Flushing the arterial line every 8 hours (B) is a routine maintenance procedure and not the immediate priority. Keeping the client's hand elevated above the heart level (D) is a good practice to prevent swelling, but it is not directly related to the arterial line care in this case.

Correct Answer: C

Rationale: The correct action the nurse should include for a client with thrombocytopenia is to provide a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Providing a stool softener helps prevent constipation, straining, and subsequent bleeding, which is crucial for clients with thrombocytopenia. Encouraging the client to floss daily (Choice A) is important for oral hygiene but not directly related to thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is more related to infection control than managing thrombocytopenia. Avoiding serving raw vegetables (Choice D) is important for clients with compromised immune systems to reduce the risk of foodborne illnesses but is not directly related to thrombocytopenia management.

Correct Answer: D

Rationale: The correct statement is D: 'An RN evaluates the client's needs to determine which tasks are appropriate to delegate to assistive personnel.' This is an essential step in the delegation process to ensure that tasks are assigned appropriately based on the client's condition and the competencies of the assistive personnel. Option A is incorrect because while the nurse retains accountability for delegation decisions, the AP is responsible for their actions. Option B is incorrect as tasks should be within the AP's scope of practice regardless of training. Option C is incorrect as delegation typically involves assigning tasks from the RN to the AP, not between APs.
