Correct Answer: B

Rationale: The correct strategy for teaching a client with low literacy about a new diagnosis of hypertension is to use simple language and visual aids. This approach helps ensure better understanding of the diagnosis and treatment plan by making the information clear and accessible. Providing a detailed handout with complex terms (Choice A) would not be suitable as it may confuse the client further. Encouraging the client to research the diagnosis online (Choice C) could lead to misinformation and overwhelm the client with information they may not understand. Incorporating medical jargon to explain the condition (Choice D) would not be helpful for a client with low literacy as it may complicate rather than clarify the information.

Correct Answer: D

Rationale: When caring for a client with active tuberculosis, it is crucial to implement negative pressure rooms and contact precautions to prevent the spread of infection. Choice A, initiating protective environment precautions, is incorrect as this is not the recommended approach for tuberculosis. Choice B, using droplet precautions only, is insufficient as tuberculosis requires additional precautions. Choice C, ensuring a positive pressure environment in the room, is incorrect because negative pressure rooms are necessary to contain airborne pathogens like tuberculosis. Therefore, the most appropriate measures include implementing negative pressure rooms and contact precautions.

Correct Answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.

Correct Answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

Correct Answer: B

Rationale: The correct recommendation for managing chemotherapy-induced fatigue is to advise the client to rest when needed and maintain a balanced diet. Increasing the dose of chemotherapy (Choice A) would exacerbate the fatigue and other side effects. While light physical activity (Choice C) can be beneficial, extreme fatigue may require more rest initially. Delaying chemotherapy treatment (Choice D) should only be considered after consultation with the healthcare provider, as timely treatment is usually crucial in cancer care.
