A nursing manager is worried about the number of infections in the hospital unit. What action by the manager would be most effective in preventing these infections?
Implement a policy to remove urinary catheters promptly.
Educate staff members about infection control methods.
Ensure patients are placed in appropriate isolation.
Monitor staff members’ hand hygiene practices.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale:
A serum sodium level of 134 mEq/L (134 mmol/L) is mildly low, but this level of hyponatremia is not typically associated with significant cognitive impairment.
Symptoms of hyponatremia, such as confusion, lethargy, and seizures, usually occur when sodium levels are 125 mEq/L or lower.
However, it's important to monitor this patient for any changes in cognitive status as hyponatremia can worsen and lead to more severe symptoms.
Choice C rationale:
A patient who underwent an open cholecystectomy two days ago may experience some cognitive impairment due to the effects of anesthesia and pain medications.
However, this type of impairment is usually temporary and resolves within a few days.
It's important to assess for cognitive impairment in this patient, but it is not the most urgent priority.
Choice D rationale:
A 32-year-old patient with a 20-pack-year history of smoking is at risk for cognitive impairment due to the long-term effects of smoking on the brain.
However, this risk is typically not as immediate as the risk of cognitive impairment following a stroke.
It's important to educate this patient about the risks of smoking and encourage smoking cessation, but it is not the most urgent priority in terms of cognitive assessment.
Choice B rationale:
An 88-year-old patient who had a hemorrhagic stroke three days ago is at the highest risk for cognitive impairment among the given options.
Hemorrhagic stroke involves bleeding in the brain, which can damage brain tissue and lead to cognitive deficits.
The risk of cognitive impairment is particularly high in older adults, as they may have less cognitive reserve to compensate for the damage caused by the stroke.
Early assessment and intervention for cognitive impairment are crucial for optimizing recovery and quality of life in stroke patients.
Prompt evaluation for cognitive impairment is essential to identify any deficits and initiate appropriate interventions to support the patient's cognitive function and recovery.
Correct Answer is A
Explanation
Choice A rationale:
Hyperventilation is a condition characterized by rapid and deep breathing, leading to excessive removal of carbon dioxide (CO2) from the body. This decrease in CO2 levels actually causes respiratory alkalosis, not respiratory acidosis.
CO2 is a weak acid, and its removal from the blood raises the blood pH, making it more alkaline. Key mechanisms involved in hyperventilation-induced respiratory alkalosis:
Increased alveolar ventilation: Hyperventilation increases the rate at which CO2 is expelled from the lungs, reducing its concentration in the blood.
Shift in the equilibrium of the carbonic acid-bicarbonate buffer system: The reduction in CO2 levels drives the equilibrium towards the formation of bicarbonate ions, further reducing the concentration of hydrogen ions and increasing pH.
Renal compensation: The kidneys respond to respiratory alkalosis by excreting more bicarbonate ions, which helps to normalize the blood pH.
Choice B rationale:
Asthma is a chronic respiratory disease characterized by inflammation and narrowing of the airways. This can lead to impaired ventilation and retention of CO2, which can contribute to respiratory acidosis.
Mechanisms by which asthma can cause respiratory acidosis:
Bronchoconstriction: Narrowed airways impede airflow, making it difficult to expel CO2 from the lungs.
Air trapping: Inflammation and mucus production can lead to air becoming trapped in the lungs, further increasing CO2 levels.
Hypoventilation: Severe asthma attacks can cause respiratory muscle fatigue, leading to a decrease in breathing rate and inadequate CO2 removal.
Choice C rationale:
Chronic obstructive pulmonary disease (COPD) is a group of lung diseases characterized by chronic obstruction of airflow. This obstruction can lead to impaired ventilation and retention of CO2, which can contribute to respiratory acidosis.
Mechanisms by which COPD can cause respiratory acidosis:
Emphysema: Destruction of lung tissue reduces the surface area available for gas exchange, making it difficult to expel CO2. Chronic bronchitis: Inflammation and mucus production in the airways can obstruct airflow and trap CO2 in the lungs.
Hypoventilation: COPD can lead to respiratory muscle fatigue and a decrease in breathing rate, further impairing CO2 removal.
Choice D rationale:
Pulmonary embolism (PE) is a blockage of an artery in the lungs, usually by a blood clot. This can lead to impaired gas exchange and a decrease in oxygen levels in the blood. In severe cases, PE can also cause respiratory acidosis due to inadequate CO2 removal.
Mechanisms by which PE can cause respiratory acidosis:
Ventilation-perfusion mismatch: PE obstructs blood flow to a portion of the lungs, reducing the amount of CO2 that can be removed from those areas.
Hypoxemia: Low oxygen levels in the blood can stimulate the respiratory drive, leading to hyperventilation and CO2 retention.
Right heart failure: PE can strain the right side of the heart, leading to decreased pulmonary blood flow and impaired CO2 removal.
