Correct Answer: A

Rationale: The correct answer is A because hiring someone to trim low-hanging branches over stairs ensures home safety and reflects an understanding of walker use. This action indicates the client's awareness of potential hazards and the importance of a safe environment for walker use. Choice B is incorrect as avoiding uneven surfaces is a general safety precaution but does not directly relate to walker use and does not demonstrate an understanding of the teaching. Choice C is incorrect because using a walker on stairs is not recommended due to safety concerns such as balance and fall risks. Choice D is incorrect as making no changes to the home environment may pose safety risks when using a walker, showing a lack of understanding regarding safety precautions needed for walker use.

Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.

Correct Answer: B

Rationale: The correct answer is B. Ground beef, lima beans, and raisins are rich sources of iron, making this meal plan the most suitable for a child with anemia. Ground beef is a high-iron meat, while lima beans and raisins are also excellent sources of iron. Fish sticks, french fries, banana, and cookies in option A lack sufficient iron content compared to the options in B. Chicken nuggets, macaroni, and peas in option C are not as iron-rich as the ground beef, lima beans, and raisins in option B. Peanut butter and jelly sandwich with apple slices in option D also fall short in providing enough iron when compared to the iron-rich components of option B.

Correct Answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.

Correct Answer: A

Rationale: To ensure accurate testing, a minimum amount of stool is required for specimen collection, typically at least 2 inches of formed stool. This amount provides an adequate sample for testing. Wearing sterile gloves is important for infection control but is not specifically required for stool specimen collection. Using a culturette is not typically necessary for collecting stool specimens. Recording the date and time the stool was collected is essential to ensure timely processing but does not directly impact the collection of the specimen itself.
