Week 1 Discussion Initial Post

Pharmacokinetics and Pharmacodynamics

A patient from my clinical experience is described as a Mr. X a 75 year male with a right hip fracture from a

fall. He had a known history new onset dementia and COPD. The patient arrived to the unit post-operative R

ORIF. He became increasingly confused over the course of his stay. He made several attempts to get out of

the bed, fought staff with care, pulled his oxygen off and lines and tubes out. He was not getting any sleep.

He had to eventually be restrained to prevent self-injury. However he aggressively attempted to get out of

his soft bilateral wrist restraints. This caused stress on his heart and increased his oxygen demand. He was

given a one-time dose of Ativan 2mg IV. The Ativan calmed him down for hours and then the cycle would

start over again. The confusion / delirium became worse. However, the IV Ativan was then scheduled and

after a few doses the patient became difficult to arouse. The patient became hypotensive and oxygen

demand required the need for intubation. Chest x-ray indicated pneumonia.

The relationship between the body and drugs is referred to as and Pharmacodynamics.

Pharmacokinetics is the study of the movement of drugs through the body. The Pharmacokinetic processes

are absorption, distribution, metabolism and excretion (Rosenthal and Burchum, 2018). Pharmacodynamics is how drugs affects the body(Rosenthal and Burchum, 2018).

Mr. X experienced a long course of recovery. The use of Ativan, his age and

co- morbidities influenced the Pharmacokinetic and Pharmacodynamic processes the patient

experienced. The elderly have a decreased metabolism and excretion of benzodiazepines ( Neft, Oetther, Halloway& Hanneman, 2019). Distribution plays a significant role in age related changes including decreased fluid volume, decreased muscle mass, organ perfusion and serum albumin concentration. The effects are altered serum concentration, drugs are in the system longer, stronger drug effects at lower doses. Resulting in increased side effects and toxicity (Kratz and Diefenbacher, 2019).

The American Geriatrics Society (AGS) placed Benzodiazepines on a list of medication to avoid in

patients over the age of 65. ( Neft, Oetther, Halloway& Hanneman, 2019). Benzodiazepines are known to

cause respiratory depression and cognitive deficits in the elderly for the reasons aforementioned (Markota et al. 2016).

I would develop a plan for Mr. X, first off I would request a sitter and ask family to come in and be with

the patient. There are many different medications he could have been given. I would try a precedex gtt and go

from there. Bradycardia is a side effect but I have seen patients do well on this medication.

Mr. X is not an uncommon patient in the ICU. However, if there is an understanding of Pharmacokinetics

with drug therapy this may increase beneficial effects and minimize unnecessary patient harm.

RE: advanced Pharm

Hi Beth

Thank you for the informative post.As effective as Ativan is, it is very risky in the elderly population like it can cause sedation, confusion, sleepiness, and so on. The American Geriatrics Society added Ativan a benzodiazepine on a medication list that should be avoided to adults 65 years and older(Markota, et al., 2016). Several significant psychiatric associations also advise against using benzodiazepines for the elderly as they are always risky (Tannenbaum, 2015). In your scenario, I would be interested in knowing whether the patient’s size was considered in relation to the needed body surface for the 2mg Ativan given, also thinking of other medications or treatments that could work safely for this older patient. However, your individualized plan of care ensures that all precautions have been addressed for the patient’s safety. Thank you for your post.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality

Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes

I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.
LopesWrite Policy

For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication

Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
