Question 48

Considering the reduction in hepatic blood flow with aging and its impact on the metabolism of drugs, which approach is MOST appropriate for the administration of drugs metabolized by the liver in elderly patients?

A.) Preference for liver-metabolized drugs at higher doses to ensure therapeutic effects, assuming that standard adult doses may not achieve desired anesthesia depth due to decreased hepatic function.
B.) Careful dosing and monitoring of drugs metabolized by hepatic cytochrome P450 enzymes, with adjustments based on anticipated reduction in clearance and the potential for prolonged effects.
C.) Avoidance of all hepatically metabolized drugs in favor of drugs with exclusive renal clearance.
D.) Uniform reduction in the dose of all medications by a fixed percentage for elderly patients, based on the average decrease in hepatic blood flow with age.

Answer 48

B.) Careful dosing and monitoring of drugs metabolized by hepatic cytochrome P450 enzymes, with adjustments based on anticipated reduction in clearance and the potential for prolonged effects.

Question 49

Given the complex etiology of postoperative delirium (POD) and its significant impact on outcomes in elderly patients, which of the following strategies is MOST effective in preventing POD according to current guidelines and consensus statements?

A.) Minimizing patient movement and physical activity until several days after surgery, as resting and avoiding potential injuries by staying immobile initially can prevent the confusion and agitation associated with delirium
B.) Using benzodiazepines consistently in the postoperative period to prevent episodes of agitation and promote calmness, as these agents help stabilize the patient and minimize risk factors associated with delirium
C.) Implementing a multicomponent intervention strategy in the postoperative period that includes sleep enhancement, cognitive reorientation, early mobilization, effective pain management, medication reconciliation, and nutrition optimization to address the multifactorial risk factors associated with POD.
D.) Ensuring high-dose opioid administration to keep the patient’s pain fully controlled, which reduces stress and indirectly helps prevent the cognitive disturbances seen in delirium, especially in elderly patients

Answer 49

C.) Implementing a multicomponent intervention strategy in the postoperative period that includes sleep enhancement, cognitive reorientation, early mobilization, effective pain management, medication reconciliation, and nutrition optimization to address the multifactorial risk factors associated with POD

Question 50

In the context of identifying elderly patients at high risk for postoperative delirium (POD), which of the following preoperative measures is MOST critical for guiding prevention strategies?

A.) Conducting an extensive neurological examination on all elderly patients to identify any underlying brain pathology, knowing this will accurately predict the patient’s risk for developing POD.
B.) Utilizing a validated screening tool to assess for preexisting cognitive impairment, frailty, and other risk factors for POD, allowing for targeted interventions and careful monitoring of at-risk patients.
C.) Limiting the preoperative assessment to the patient’s history of previous episodes of delirium
D.) Assuming that all elderly patients are at an equally high risk for POD and therefore uniformly applying intensive prevention measures without individualized risk assessment.

Answer 50

B.) Utilizing a validated screening tool to assess for preexisting cognitive impairment, frailty, and other risk factors for POD, allowing for targeted interventions and careful monitoring of at-risk patients.

Question 51

Considering the unique challenges in managing acute postoperative pain in elderly patients with cognitive dysfunction, which of the following pain management strategies is MOST appropriate to minimize potential complications associated with pharmacological treatment?

A.) Avoiding or using caution with specific analgesics, such as meperidine and agonist-antagonist opioids, which are known to have pronounced side effects in the elderly, and referencing Beer’s criteria to guide the selection of safer analgesic options.
B.) Defaulting to high-dose opioid therapy for all elderly patients with acute postoperative pain, recognizing the decreased sensitivity to opioids and the lower risk of adverse effects in this population.
C.) Exclusively using non-pharmacological pain management techniques, such as physical therapy and relaxation methods, to completely avoid the risk of drug-related side effects in elderly patients with cognitive dysfunction.
D.) Applying a one-size-fits-all approach to analgesic selection.

Answer 51

A.) Avoiding or using caution with specific analgesics, such as meperidine and agonist-antagonist opioids, which are known to have pronounced side effects in the elderly, and referencing Beer’s criteria to guide the selection of safer analgesic options.
