A nurse is caring for a client who has a peritoneal catheter that requires a dressing change.
Identify the sequence of actions the nurse should take.
Apply precut gauze pads to the site.
Create a sterile field.
Mask self and the client.
Cleanse the site with povidone-iodine.
Correct Answer : A,B,C,D,E
Choice E rationale
Removing the old dressing is the first step in a dressing change procedure. It must be done to visualize the site and assess for signs of infection or other complications. Proper removal also prevents contamination of the new dressing materials and allows for thorough cleansing of the area before a new dressing is applied, which is a critical step in maintaining aseptic technique.
Choice C rationale
Masking is a crucial step in maintaining a sterile field and preventing cross-contamination. Donning a mask protects the client from respiratory microorganisms of the nurse and protects the nurse from potential splashes or aerosolized particles from the client's catheter site. This step is performed after removing the old dressing but before creating the sterile field to minimize contamination risk.
Choice B rationale
Creating a sterile field is an essential step in preventing microbial contamination of the catheter site. A sterile field provides a clean, controlled environment for sterile supplies and equipment. The nurse must establish this field after donning a mask and before touching any sterile items to ensure that the materials used for the dressing change remain free of pathogens.
Choice D rationale
Cleansing the site with an antiseptic solution like povidone-iodine is a critical step to reduce the bacterial load and prevent infection. This action is performed after the sterile field is established but before applying the new dressing. The antiseptic solution disrupts microbial cell membranes and inactivates enzymes, thus reducing the risk of a catheter-associated bloodstream infection.
Choice A rationale
Applying precut gauze pads is the final step in the sequence. These pads provide a protective barrier over the cleansed site, absorb any drainage, and prevent environmental microorganisms from entering the site. This action is taken after the site has been thoroughly cleaned and dried, ensuring that the new dressing remains sterile and effective. *.

Correct Answer is D
Explanation
Choice A rationale
A guardian's statement that a child fell off a swing is a common and plausible explanation for a fractured arm. This type of injury is consistent with the normal activities of a preschooler, and it does not inherently suggest abuse. The nurse should continue with a thorough physical assessment and gather additional history, but this statement alone is not a red flag.
Choice B rationale
Crying loudly when a fractured arm is moved is a normal, expected reaction to pain. The child is experiencing acute pain from the injury, and any movement of the affected limb would cause a significant increase in discomfort. This is not a warning sign of maltreatment but rather a natural physiological response to a painful stimulus.
Choice C rationale
A guardian wanting to accompany a child to the radiology department is a typical and often protective behavior. Many parents wish to provide emotional support to their child during stressful medical procedures. This action demonstrates parental involvement and concern for the child's well-being and is not indicative of abuse or neglect.
Choice D rationale
A delay in seeking medical care for a significant injury, such as a fractured arm, is a major red flag for child maltreatment. This delay suggests that the guardian may be attempting to hide the cause of the injury or is neglectful of the child's health needs. Timely medical attention for a painful injury is the standard of care. .
Correct Answer is B
Explanation
Choice A rationale
Cranberry juice has a low pH, creating an acidic environment in the gastrointestinal tract which can help to neutralize bacteria and reduce malodorous compounds like indole and skatole, thereby decreasing odor. This action is beneficial, so avoiding it is not the correct advice for odor control.
Choice B rationale
Breath mints or commercial deodorizers contain ingredients like peppermint or chlorophyll that chemically neutralize odor-causing volatile sulfur compounds produced during digestion. Placing a breath mint inside the ostomy pouch releases these agents, effectively masking and reducing the unpleasant smell from gas and stool.
Choice C rationale
Eggs are a rich source of sulfur-containing amino acids, such as cysteine and methionine. When these are digested by intestinal bacteria, they produce hydrogen sulfide gas, which is the primary contributor to a strong, unpleasant odor and increased flatus. Consuming eggs would exacerbate the problem.
Choice D rationale
Sugar-free gum often contains sugar alcohols like sorbitol or xylitol. These are poorly absorbed in the small intestine and are fermented by colonic bacteria, leading to the production of gas. This can increase flatus and may contribute to bloating and discomfort for the client.
