Geriatric Pharmacotherapy and Medication Challenges
Prescription Problems in Elderly Patients
In elderly patients, prescriptions, over the counter (OTC), and herbals may cause problems because they suffer from several chronic disorders resulting in the excessive use of drugs compared to any other age group. It can be understood by the diminished physiological reverse, which is mostly associated with aging and can further be depleted by the chronic or acute state of diseases and drug effects. OTCs like sedatives among the elderly patients are said to cause an increase in the number of falls. These are the major concerns for the older adults because the use of multiple medications increases the risk of drug-drug counteractions and other adverse effects (Adams & Urban, 2016).
Major Physiological Changes of Aging
Pharmacokinetic changes
· Renal functioning experiences potential decrease
· Hepatic drug metabolism is also affected by aging.
Pharmacodynamics changes
· Older patients become more sensitive to effects of medications
· Some elderly patients may demonstrate decreased responses to certain medications and their adrenergic system.
Hypoglycemia unawareness
· The response of an elderly’s central nervous system decreases resulting in decreased neural density.
· The sensory, motor and autonomic fibers of an older adult are lost.
· Aging results in the decrease of tonic parasympathetic...
Therefore, the method is useful when evaluating the appropriateness of prescribing. The other advantage of Beers Criteria is that it gives information of each drug formulation that has been prescribed to elderly patients as it assesses its appropriateness. In geriatric patients, Beers criterion is a method used in evaluating the rationality of prescriptions. The con of this criterion is that it consumes much time (Adams & Urban, 2016).
Beers Criteria is an Evidence-based Medicine (EBM). The excessively rigid application of clinical guidelines and evidence in patient care has resulted in ‘cookbook medicine’ practice. Moreover, the clinical practice applied by Beers Criteria may be appropriate resulting in the suboptimal care given to patients. In the process, encountering inappropriate care that leads to harming some patients. Furthermore, part of physicians will become discouraged and eventually lead to the downgrading of good clinicians regarding their reasoning capacity and judgment (Adams & Urban, 2016).
Age-Related Physiological Changes on Drug Response in Older Adults
Age-related physiological changes alter pharmacokinetics because the variability in renal decline implies that dosing decisions for such…

(Fletcher; Inciardi; Tims, 1993) This may be the reason that there is today a new concept in the treatment of drug abuse, and this is the creation of 'Mobile Health Services'. In Maryland, for example, this mobile clinic has successfully treated about 30,000 to 40,000 drug abusers, about 25,000 abusers of cocaine, and more than 70,000 users of alcohol. If this idea of serving the community by the deployment of
As indicated by Miller & Rollnick (1991), confronting a client might leave them with a feeling of being under attack. This may then reduce their urge of being treated. Zweben, Miller, Rychtarik, DiClemente (1992) indicated that most people would resist the advice of a counselor by constantly reacting as well as acting in the opposite manner to what the counselor wants them to act. The other principle of motivational thinking
Nurses and Communication Nurses play an important role in the care of patients with critical illnesses and patients that are sedated. Communicating with patients that are critically ill and sedated can be a huge challenge for nurses. This challenge exists because critically ill and sedated patients are sometimes not in a position to make decisions for themselves. For the critically ill, there are added stressors and the patient may be very aware
Difficult Patients Mitigating Risks from Dementia Providing adequate care for an individual suffering from dementia presents many difficulties for nurses. Patients with dementia often have debilitating conditions such as Alzheimer's or similar neurologic diseases which are progressive, thereby making it challenging for them to remember, think lucidly, communicate effectively or complete activities of daily living. Furthermore, dementia can cause rapid variations in mood or even modify personality and behavior. With the
Analysis of Quality Improvement in Healthcare-Patient AdvocacyProblem Area and Current ProcessThe quality improvement project I am planning to implement will focus on patient advocacy. According to Nsiah et al. (2020), patient advocacy is the process by which nurses act on behalf of patients by becoming their voices so as to ensure that their rights are defended and their needs are met. Most nursing theorists agree that patient advocacy is essential
Usually, both physical and psychological components need to be addressed. Byrd (2001) explains, the function of brain cells (neurons) is affected when a drug is used repeatedly over a long period of time. Each neuron produces and releases chemicals called neurotransmitters. These neurotransmitters can impact the function of the nerve cell, making it produce and release hormones. "The neurotransmitters that have been associated with addiction include serotonin, dopamine, norepinephrine,
