The Furosemide (Lasix) which lessen the fluid volume by escalate the amount of electrolytes and water that the kidneys are getting rid of. When there is less fluid volume the blood pressure will go down. Since her blood pressure is decreasing, the rate of her heart beat will decrease, diminish the amount of work that the heart has to do, and lowering how much fluid has built up in the lungs.
The nurse needs to know how fast Furosemide (Lasix) should be given, how it work with other intravenous liquids, and what Lasix’s concentration is.
The Foley catheter was ordered so it would accurately measure how much fluid was being released due to the Lasix (furosemide).
The nurse should look at her blood pressure, respirations, temperature, pulse, pulse ox, and pain. He or she should also look for sluggishness and unsureness which are signs of hyponatremia; hyperkinesis, uncontrollable muscle spasm, easily upset which are symptoms of hypochloremia; thromboembolism which can be indicated by pain in lower extremities, migraine, inability to breathe, change in level of consciousness, and pain in chest.
The nurse needs to let the prescriber know that all though the client’s potassium level was normal it was low in the normal range at the time the labs were drawn, Lasix can cause a drop in potassium, chloride, and sodium. He or she also needs to find out if the patient is currently on a regimen containing digoxin since that cause too much sodium in the body which can lead to the digoxin levels becoming toxic.
The most likely reason for the symptoms the client came in with is how much she has been eating her favorite foods which is high in salt.
The nurse needs to check the clients blood pressure laying down, sitting up, and standing, ascultate her lungs for normalcy and absence of rales, weight, how much fluids have been consumed and excreted, swelling, pain on movement, and difference in hearing.
The client needs to know that it is best to partake in foods low in sodium. Lasix and spironolactone may cause her to need to increase her potassium intake. She needs to take her medications regularly and monitor her levels with lab test. The prescriber also needs to be kept informed of whats going on. Because of her conditions and the medicine that she is taking she has to beware of differences in hearing and not enough calcium which can manifest in being very dehydrated, uncertainty, heartbeat not being normal, and weakness in muscles. She also needs to be cautioned that with her orthostatic blood pressure she needs to take extra care when changing positions of altitude it should be done slowly such as sitting to standing.
The client needs to be warned about taking any medications without letting her prescriber know first such as anything herbal, over the counter, or natural. Tests for potassium and digoxin levels need to be preformed regularly since Lasix can increase the chance of having toxic levels of digoxin in the body. Toxic levels of digoxin can present itself upset stomach and the inability to eat.

...Pharmacology is the study of the physical, biological and chemical actions of drugs (Bryant & Knights, 2011). In the practice of medicine, drugs are used to diagnose, treat or prevent disease so for the registered nurse in a clinical setting, the knowledge of pharmacology plays a huge importance in their role of medication administration. Pharmacology knowledge allows the nurse to carry out safe medication administration, monitor medication actions, educate patients, and act legally and ethically within the pharmacological parameters. This knowledge is also vital for the nurse practititioner in their role of nurse prescribing. Pharmacology plays a huge part in these roles for the nurse. This essay below will elaborate on the importance of pharmacology for the five reasons of safe medication administration, monitoring of medication actions, patient education, legal and ethical aspects of pharmacology and the nurse practitioner. Firstly, safe medication administration. To administer drugs safely it is the nurse’s responsibility to have knowledge of the prescribed medications as well as their therapeutic and non therapeutic effects. Knowledge of the medications include, knowing its approved drug name and classification, correct dose and route of administration. A medication may have as many as three different names- a chemical name, a generic (proprietary) name and a trade name (Crisp & Taylor, 2011). A chemical name refers to the chemical makeup of a drug, a generic name is the...

Which dosage forms are most appropriate for administering drugs to pediatric patients? Adults? Medication administration to a pediatric patient can be challenging. Prescribers should order dosage forms that are age appropriate for their patients. The drug delivery industry offers a full array of innovative dosage forms, which are suitable for pediatric patients of all ages. As for adults, the appropriate dosage forms for adults should be based on the specific needs of the patient. Dosage form depends on the patients’ delivery method of the medication (Olson, J., 2006). 2. What are the processes involved in disintegration and dissolution? According to Grand Canyon University Lecture 1, (2011), “These terms describe the processes by which the medication is broken down within the body and delivered to the cells. Some medications are designed to breakdown quickly and be carried away by the blood stream. Nitroglycerin is an example of this process. When a patient puts nitroglycerin under the tongue, it immediately disintegrates and dissolves into a solution to be dispersed to relieve angina. Manufactures of the drug can design it in such a way as to control the speed of disintegration and dissolution (Grand Canyon University Lecture 1, 2011). 3. Give a definition of pharmacokinetics...

...When administering medications to patients with dementia or delirium it is important to have an understanding of what dementia and delirium means. Delirium is an acute reversible state of disorientation and confusion. Delirium is marked by disorientation without drowsiness, hallucinations, delusions; difficulty in focusing attention; inability to rest and physical and autonomic over activity. Common causes of delirium are drug and alcohol withdrawal; medication side effects, infections, pain surgery or trauma, hypoxia, and acid-base electrolyte imbalances. Treatment of delirium includes determining the cause of the delirium. Antipsychotic drugs and benzodiazepines may be used cautiously when other non-pharmacological interventions have failed. (Tabors 2009) Dementia is a progressive irreversible decline in mental function marked by memory impairment and often deficits in reasoning, judgment, abstract thought registration, comprehension, learning, and use of language. Symptoms may take months to years to progress and they include poor judgment, clouding of consciousness and orientation, depression, agitation sleeplessness, Patient may become dependent of activities of daily living. Dementia may result from AIDS, chronic alcoholism, Alzheimer’s disease, vitamin B12 deficiency, carbon monoxide poising, hypothyroidism and subdural hematomas. 4.5 million People in the U.S are affected by dementia. 20-40% of patients with dementia are over the age of 85.

Components of Pharmacology

...Components of Pharmacology Stacy Maryland Liberty University Online Pharmacology Pharmacology is the study of drugs; manmade, organic, or endogenous, and their application and physiological effect(s) most specifically on the central nervous system (CNS). The Doweiko text succinctly describes a pharmaceutical as that which is responsible for, “changing the biological functions of target cells through chemical action” (2015, p. 16). Drugs both licit and illicit, are largely classified as depressants, hallucinogens, opiates, and stimulants, come in myriad forms, allow for multiple avenues of consumption, and have inherent side effects. When developing, dispensing, or using a drug, it is necessary to understand the aforementioned, as well as its half-life, effective and lethal doses, potential interactions, and consequences of abuse or misuse. What is desired from a drug is its optimum effect or highest potential, which is contingent on its bioavailability and a rather complex process of being metabolized in the body. All substances have an effect on the body known as its half-life. Drug half-life, divided into three categories: distribution half-life, therapeutic half-life, and elimination half-life. It essentially refers to a compound’s effectiveness, duration of effect, and time in the body, respectively (Doweiko, 2015, p. 23). Every drug has a preferred effect. This intended outcome is referred to as its prime or desired effect. As previously stated, each of these...

What are two interventions that would help this couple take the correct medications at the correct times and on the correct days? An intervention that would help the couple with medications is one of the grown children can move closer to their parents. The child can monitor the couple more to ensure medication is taken correctly and at the right times. Another intervention to assist the couple is to have the medication measured out for the entire week. The family can do that. The insulin can be premeasured in the syringes and labeled with the time it is to be taken. The pills can be put in a medicine container or egg box that is labeled for the different days of the week. The process would start over on Sunday. Having a medication calendar can assist the family in taking the right amounts. The family can have a bell that goes off during the day when it is time to take medicines. Education is the key for the family to know and understand the importance of medication management.

...Medication errors are flaws in the healthcare system that can result in injury, disease, and even death. There are ways to prevent these mistakes and to make a facility more safe by enforcing certain rules and regulations. In order for these rules to be effective, the entire healthcare team including doctors, nurses, pharmacy, etc., need to cooperate and work together. It's very common for someone to make a clumsy move which is why triple checking is becoming more and more effective today. First scenario: A patient was prescribed two completely different medications to her but with similar names. The first drug was hydroxyzine 100 mg PO QID as needed and the second was hydrochlorothiazide 25 mg PO daily. When the nurse was supposed to be giving the 100 mg dose of hydroxyzine they instead pulled four 25 mg hydrochlorothiazide pills from the automated dispensing cabinet. The nurse proceeded to administer the medication before using the barcode scanning system. Not using the barcode was her first mistake. The nurse scanned the barcode after the patient had already consumed the pills. A pop up error came up saying "medication not found" because the daily dose of hydrochlorothiazide had already been given that day. Thankfully, the patient survived this incorrect administration of medication with no side effects to report. The nurse in this scenario administered the wrong medication that ended up being four times the prescribed dose of something that had already been given...

...MONONUCLEOSIS Also known as “MONO” Mononucleosis is a common illness that can leave you feeling tired and weak for weeks or months. It goes away on its own, but lots of rest and good self-care can help you feel better. Illness usually caused by the Epstein-Barr virus (EBV). Often seen in teens and young adults, children can get the virus, but it often goes unnoticed because their symptoms are mild. Mono can be spread through contact with saliva, mucus from the nose, throat and sometimes tears. This is known as the kissing disease. However, Mononucleosis isn’t as contagious as some infections, such as the common cold. If you have mono, it’s important to be careful of certain complications such as an enlarged spleen. Rest and adequate fluids are key to recovery. Epstein-Barr is a very common virus. About 85% to 90% of American adults have developed antibodies by the time they are 40 years old. Which means that they have been infected with the virus at some point in their lives. This Disease is usually diagnosed based on the patient’s symptoms such as: Fever, swollen tonsils, and swollen lymph nodes in your neck and arm pits, skin rash and strep throat that doesn’t get better with antibiotic use. The doctor may order blood tests, particularly the mono spot test. Other blood tests, such as a complete blood count, might be done to see if the number of lymphocytes is higher than normal. Occasionally, titers of antibodies against the viruses that cause mono may need to be...

...Phenomenology According to Potter and Perry (2010) phenomenology is understanding of human experiences as it is experienced. It is understanding and feeling the experiences as it is lived by an individual. Phenomenology is understanding the viewpoint of individuals as they experience it. According to phenomenological perspective an individual’s reality is created through the meanings they attribute to experience. Consequently, an individual’s world is the individual itself and the meaning and relationships they give to everyday experiences. One aspect of phenomenology is the holistic perspective that studies the ‘whole’ phenomenon (CNP BC 2009). Accordingly, holistic perspective sees an individual as a whole individual and not in segments or parts. Similarly, nursing considers the whole person and values their experience. Besides, the central focus of nursing is the client. The client includes the physical, emotional, psychological, spiritual and social dimensions of the individual (Potter & Perry, 2010). Phenomenological perspective will help the writer to understand a nurses role as to be empathic, to be perceptive and to be supportive. It will assist the writer to understand individuals’ experiences as valid and be supportive. Phenomenology will help me to encourage and empower individual to take control over their health and wellness. Phenomenology will assist me to actively listen to individuals, create a therapeutic relationship and respect them. Phenomenological...

...JOHANA WOULMS 1. Explain what endometriosis is, how it develops, and what specific drugs are used to treat it. What is endometriosis? Often painful disorder in which tissue that normally lines the inside of your uterus, the endometrium grows outside your uterus (endometrial implant). Endometriosis most commonly involves your ovaries, bowel or the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond your pelvic region. How does endometriosis develop? In endometriosis, displaced endometrial tissue continues to act as it normally would — it thickens, breaks down and bleeds with each menstrual cycle. Because this displaced tissue has no way to exit your body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form. Surrounding tissue can become irritated, eventually developing scar tissue and adhesions — abnormal tissue that binds organs together. What specific drugs are used to treat endometriosis?. Dnazol, gosereli (Zoladex), leuprolide (Lupron Depot), nafarelin (Synarel), norethindrone (Aygestin) are hormone drugs used to suppress the menstrual cycle for several months, during which the endometrial implants shrink and fade 2.
