An older adult male client tells the nurse of losing sleep because of having to get up several times at night to go to the bathroom. The client also reports having trouble starting his urinary stream, and he does not feel like his bladder is ever completely empty. Which intervention should the nurse implement?

Choice A reason: Respiratory acidosis is characterized by a low pH and an elevated PaCO2 due to hypoventilation, which results in CO2 retention. The ABG results in this case show a normal PaCO2, making this option incorrect.

Choice B reason: Metabolic acidosis is characterized by a low pH and a low HCO3 due to an accumulation of acids or loss of bicarbonate. The ABG results show a high pH and a high HCO3, which are opposite to the findings of metabolic acidosis.

Choice C reason: Metabolic alkalosis is characterized by a high pH and an elevated HCO3. This condition can result from excessive loss of stomach acid due to vomiting or the use of diuretics. The ABG results show a pH of 7.50 and HCO3 of 33 me/L, both indicative of metabolic alkalosis.

Choice D reason: Respiratory alkalosis is characterized by a high pH and a low PaCO2 due to hyperventilation, which leads to CO2 loss. The ABG results show a normal PaCO2, ruling out respiratory alkalosis as the correct diagnosis.

Choice A reason: Withholding further opioid analgesics might be considered if the lack of bowel sounds is due to opioid-induced ileus. However, this is not the immediate action the nurse should take. The nurse should first document the finding and continue to assess the client's condition.

Choice B reason: Obtaining a prescription for a laxative might be appropriate if the client is experiencing constipation. However, administering a laxative without further assessment and documentation of the bowel sounds could lead to complications. The nurse should document the finding first and then collaborate with the healthcare provider for further interventions.

Choice C reason: Documenting the assessment finding is the most appropriate initial action. This ensures that the lack of bowel sounds is recorded in the client's medical record, which is crucial for ongoing monitoring and communication with the healthcare team. Proper documentation also helps in tracking changes in the client's condition and making informed decisions about subsequent care.

Choice D reason: Preparing to insert a nasogastric tube might be necessary if the client develops symptoms of bowel obstruction or other complications. However, this action should follow the documentation and further assessment of the client's condition. The nurse should document the finding first to provide a basis for any further interventions.
