Choice A rationale:
Tolerance to the opiate medication is developing. This is the most likely explanation for why the client's pain is no longer being controlled by the same dose of medication. Tolerance is a physiological adaptation that occurs with repeated exposure to opioids, leading to a decrease in their effectiveness over time. This means that the client's body is becoming less responsive to the medication, and a higher dose is needed to achieve the same level of pain relief.
Choice B rationale:
There is likely a history of addiction. While it is possible that the client has a history of addiction, this is not the most likely explanation for why the medication is no longer controlling the pain. Addiction is a complex condition that is characterized by compulsive drug seeking and use, despite negative consequences. It is not simply a matter of tolerance developing.
Choice C rationale:
The client is opiate naive. This means that the client has not previously been exposed to opioids. While opiate-naive clients may be more sensitive to the effects of opioids, they are also more likely to experience side effects, such as nausea and vomiting. The fact that the client has been receiving the same dose of medication for 2 days without experiencing side effects suggests that they are not opiate naive.
Choice D rationale:
Physical dependence. Physical dependence is a state of adaptation that occurs with repeated exposure to opioids, leading to withdrawal symptoms if the medication is abruptly stopped. However, physical dependence does not necessarily mean that the medication is no longer effective in controlling pain.

Choice A rationale:

While promptly removing urinary catheters can reduce the risk of catheter-associated urinary tract infections (CAUTIs), it addresses only one specific type of infection. It doesn't comprehensively address other common healthcare-associated infections (HAIs) like central line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), ventilator-associated pneumonia (VAP), and Clostridium difficile infections (CDI).

Education about infection control methods, however, encompasses a broader range of preventive measures that can be applied to various HAIs, making it a more effective strategy for overall infection prevention.

Choice C rationale:

Placing patients in appropriate isolation can prevent the spread of infections, but it's a reactive measure that's implemented after an infection has already occurred. It doesn't address the root causes of infections or prevent their occurrence in the first place.

Education about infection control methods, on the other hand, is a proactive approach that aims to prevent infections from happening in the first place by teaching staff about proper hygiene practices, aseptic techniques, and other infection prevention strategies.

Choice D rationale:

Monitoring hand hygiene practices is crucial for infection prevention, but it's only one aspect of a comprehensive infection control program. Education about infection control methods goes beyond hand hygiene and covers various other preventive measures, such as:

Proper use of personal protective equipment (PPE) Aseptic technique during invasive procedures

Proper cleaning and disinfection of equipment and surfaces Proper handling of patient waste

Recognition of signs and symptoms of infection Prompt reporting of potential outbreaks

Therefore, educating staff members about infection control methods is the most effective action the nursing manager can take to prevent infections in the hospital unit because it provides a comprehensive approach to infection prevention, addressing various aspects of HAI prevention and promoting a culture of safety among healthcare staff.
