The ability to mentally understand that 1 + 3 = 4 and 4 - 3 = 1 occurs in which stage of cognitive development?
Preoperational stage.
Intuitive thought stage.
Concrete operations stage.
Formal operations stage.
The Correct Answer is C
The correct answer is choice C: Concrete operations stage.
Choice A rationale:
The preoperational stage, which occurs roughly between ages 2 and 7, is characterized by egocentrism, animism, and a lack of conservation. Children in this stage struggle with understanding that quantities can remain the same even if their appearance changes. For instance, they might think that pouring water from a tall glass into a short, wide glass somehow changes the amount of water. This stage does not demonstrate the mental understanding required for the examples given in the question.
Choice B rationale:
The intuitive thought stage, which typically spans from ages 4 to 7, is marked by increased symbolic thinking but still lacks the capacity for logical and systematic reasoning. Children in this stage might be able to count and perform basic arithmetic, but they struggle with more complex operations and understanding the underlying principles of mathematical operations. This stage is not where the ability to understand the given math operations is firmly established.
Choice C rationale:
The concrete operations stage, which encompasses ages 7 to 11, is characterized by the development of logical and systematic thinking. Children in this stage are capable of understanding basic mathematical principles and operations, such as conservation of quantity and simple arithmetic. They can mentally manipulate numbers and understand that reversing an operation will yield the original quantity. Therefore, this stage is when the ability to understand that 1 + 3 = 4 and 4 - 3 = 1 occurs.
Choice D rationale:
The formal operations stage, typically beginning around age 11, is characterized by abstract and hypothetical thinking. This is when adolescents and adults can engage in complex reasoning and consider multiple possibilities and outcomes. The given math operations are not the focus of this stage; rather, it pertains to more advanced cognitive abilities like hypothetical problem-solving and deductive reasoning.

Correct Answer is D
Explanation
Answer is: d. Apply direct pressure above the catheterization site.
Explanation: The first action should be to apply direct pressure above the catheterization site to help control the bleeding and minimize blood loss. This will also give the nurse time to prepare additional interventions or supplies if necessary.
Choice a. is wrong because placing the child in the Trendelenburg position is not an appropriate initial nursing action in this scenario. This position can increase intracranial pressure and is typically used for patients experiencing shock or hypotension.
Choice b. is wrong because applying a new bandage with more pressure might be a subsequent action, but the priority is to apply direct pressure to slow down the bleeding.
Choice c. is wrong because notifying the physician is important, but the nurse should first take immediate action to control the bleeding and minimize potential harm to the patient.
Correct Answer is A
Explanation
The correct answer is choice A. Wearing cotton underpants.
Choice A rationale:
Wearing cotton underpants is the recommended option to prevent urinary tract infections (UTIs) in young girls. Cotton underpants allow better air circulation, which helps to keep the perineal area dry. This reduces the growth of bacteria and prevents moisture buildup, which are crucial in preventing UTIs. Synthetic fabrics can trap moisture and create a conducive environment for bacterial growth, increasing the risk of UTIs.
Choice B rationale:
Limiting bathing as much as possible is not an appropriate recommendation for preventing UTIs. Hygiene is essential to prevent UTIs, and regular bathing is part of maintaining cleanliness. Overly limiting bathing can lead to poor hygiene practices and may not significantly prevent UTIs, as they are often caused by factors beyond bathing frequency.
Choice C rationale:
Increasing fluids and decreasing salt intake can be beneficial for overall health but may not directly prevent UTIs. While staying hydrated is important for maintaining urinary health, simply increasing fluids and reducing salt intake might not be sufficient to prevent UTIs. Hygiene practices and proper perineal care play a more significant role in preventing UTIs.
Choice D rationale:
Cleansing the perineum with water after voiding is a good hygiene practice, but it alone may not be enough to prevent UTIs. While maintaining cleanliness is crucial, using water to cleanse the perineum after voiding should be combined with other practices, such as wearing cotton underpants and proper wiping techniques, to effectively prevent UTIs.
