A nurse is preparing to administer medication to a preschooler and must convert the child's weight from pounds to kilograms. The child weighs 30 lb. How many kilograms does the child weigh?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is choice B. Remove the cover gown in the client’s room after providing care. This is because Clostridium difficile spores are not effectively killed by alcohol-based hand rubs and can survive on surfaces for a long time. Removing the gown in the client’s room helps to contain any spores that may have settled on the gown, preventing them from being spread to other areas.

Choice A rationale:

Cleaning hands with an alcohol-based hand rub immediately after removing gloves is wrong because C. difficile spores are resistant to alcohol-based hand rubs. The recommended practice is thorough handwashing with soap and water to physically remove the spores from the hands.

Choice C rationale:

Placing the client in a room with negative-pressure airflow is wrong because this measure is used for airborne infections, such as tuberculosis. C. difficile is spread via the fecal-oral route, primarily through contact with contaminated surfaces or hands, not through the air.

Choice D rationale:

Wearing a mask when administering oral medications to the client is wrong because C. difficile is not spread through respiratory droplets. Masks are not necessary unless there is a risk of splash or spray of contaminated material.

The correct answer is choice A. Perform a bladder scan.

Choice A rationale:

Performing a bladder scan is the first action the nurse should take before proceeding with intermittent urinary catheterization. A bladder scan assesses the bladder's volume and determines if catheterization is necessary. It helps avoid unnecessary catheterizations, reduces the risk of infection, and promotes patient comfort.

Choice B rationale:

While cleansing the meatus and providing perineal care are important steps in preparing for urinary catheterization, they come after assessing the need for catheterization. Without knowing the bladder volume, these actions could be premature.

Choice C rationale:

Providing perineal care is important for maintaining hygiene and preventing infection, but it should be done after the decision for catheterization has been made based on the bladder scan results.

Choice D rationale:

Lubricating the catheter is a step that should be taken after the decision for catheterization is made and the need for catheterization is confirmed. It helps ease the insertion process and reduce discomfort for the patient.
