Calcium carbonate is given with meals to a child with chronic renal disease. The purpose of this is to achieve which desired result?

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.

The correct answer is choice B: "I have to stay on strict bed rest for 3 days."

Choice A rationale:

The statement "I should avoid tub baths but may shower" is correct. After a cardiac catheterization, the patient needs to keep the insertion site clean and dry to prevent infection. Showering is allowed, but tub baths should be avoided to minimize the risk of introducing water into the insertion site.

Choice B rationale:

The statement "I have to stay on strict bed rest for 3 days" is incorrect. Bed rest is not typically required after a cardiac catheterization. While the patient might need to lie flat for a few hours after the procedure to prevent bleeding and ensure hemostasis, strict bed rest for three days is unnecessary and could lead to complications like deep vein thrombosis (DVT) or deconditioning.

Choice C rationale:

The statement "I may attend school but should avoid exercise for several days" is correct. Attending school is generally acceptable after a cardiac catheterization, but exercise should be limited for several days to allow the insertion site to heal and to prevent complications like bleeding or hematoma formation.

Choice D rationale:

The statement "I should remove the pressure dressing the day after the procedure" is correct. Pressure dressings are typically removed by healthcare professionals after a specified period, which is usually around 24 hours after the procedure. Removing the dressing on their own the day after the procedure could lead to disruption of the wound and increase the risk of infection.
