Correct Answer: A

Rationale: The correct answer is A: 'I should increase my intake of foods high in iron.' Iron-deficiency anemia is managed by increasing the consumption of iron-rich foods to improve iron levels in the body. Foods high in iron include red meat, poultry, fish, beans, lentils, and iron-fortified cereals. Choices B, C, and D are incorrect because decreasing intake of iron-rich foods or increasing intake of calcium-rich foods would not address the deficiency in iron levels that characterizes iron-deficiency anemia.

Correct Answer: A

Rationale: Hyperoxygenating the client before suctioning is crucial to prevent hypoxia during the procedure. By using a manual resuscitation bag with 100% oxygen, the nurse should provide several breaths to the client to ensure sufficient oxygenation before starting suctioning. This approach helps maintain oxygen levels and decreases the risk of hypoxia, which may arise when suctioning interrupts the normal respiratory process. Choices B, C, and D are incorrect because inserting the catheter during exhalation, applying suction while inserting the catheter, and limiting suctioning to 15 seconds do not address the priority of hyperoxygenating the client to prevent hypoxia.

Correct Answer: B

Rationale: Measuring the tube from the client's nose to the earlobe to the xiphoid process ensures the tube is inserted to the correct depth. This measurement helps prevent complications such as tube misplacement or lung insertion. Positioning the client with the head of the bed elevated to 30° is important to facilitate easier insertion but is not the most crucial step. Lubricating the entire length of the tube with water-soluble lubricant is essential for smooth insertion but is not the most critical action. Instructing the client to cough during insertion is not necessary and may lead to unnecessary discomfort.

Correct Answer: A

Rationale: The correct answer is A: Avoid beverages containing caffeine. Caffeine is a stimulant that can interfere with sleep, making it difficult for the client to fall asleep at night. Taking sleep medication regularly (choice B) may not address the root cause of the sleep difficulty and can lead to dependency. Watching television in bed (choice C) can actually stimulate the brain and hinder relaxation before sleep. Advising the client to take several naps during the day (choice D) can disrupt the sleep-wake cycle further. Therefore, recommending the avoidance of caffeine-containing beverages is the most appropriate intervention to help the client improve their ability to sleep at night and function better during the day.

Correct Answer: A

Rationale: The correct answer is A. Increasing intake of foods high in vitamin D is beneficial for improving calcium absorption and managing osteoporosis. Vitamin D helps the body absorb calcium, which is essential for bone health and can aid in managing osteoporosis effectively. Choice B is incorrect because reducing calcium intake would be counterproductive for a client with osteoporosis, as calcium is crucial for bone strength. Choice C is incorrect as phosphorus, while important for bone health, does not directly impact osteoporosis management as much as vitamin D and calcium. Choice D is incorrect as potassium is not directly linked to osteoporosis management, and reducing its intake is not typically part of dietary recommendations for osteoporosis.
