Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' When developing educational materials for older clients with new antihypertensive medications, it is essential to include characteristics such as using pictures to illustrate complex ideas, providing a list with definitions of unfamiliar terms, and using common words with few syllables. These features help enhance understanding and medication adherence, especially for older adults who may have challenges with health literacy. Choices A, B, and C collectively address the need for simplicity, visual support, and clarification of terms in educational materials, making them crucial for effective patient education.

Correct Answer: D

Rationale: The correct answer is D. A preschooler with intermittent alertness episodes is not a suitable candidate for patient-controlled analgesia (PCA) due to their inability to effectively manage the system. In the context of terminal cancer, it is crucial for the patient to be able to utilize the PCA system appropriately to manage pain effectively. Preschoolers may not have the cognitive ability or understanding to operate a PCA pump compared to the other clients. Choices A, B, and C present clients with conditions that do not inherently impede their ability to use a PCA pump effectively.

Correct Answer: D

Rationale: The most important teaching point for a client prescribed methotrexate is to avoid direct sunlight to prevent photosensitivity. Methotrexate can make the skin more sensitive to sunlight, increasing the risk of sunburn and skin damage. Choices A, B, and C are important aspects of client care but are not specifically related to the side effect of photosensitivity caused by methotrexate.

Correct Answer: B

Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client receiving IV antibiotics for sepsis reports itching and a rash on the chest is to stop the infusion and notify the healthcare provider. This is crucial in preventing the allergic reaction from worsening. Administering an antihistamine (choice A) may address the symptoms but does not address the primary concern of stopping the infusion. Slowing the infusion rate and monitoring the client (choice C) may not be sufficient if the reaction is severe. Administering epinephrine subcutaneously (choice D) is not the first-line intervention for this situation.
