Remember to cite your references in APA format. Answer the questions in complete sentences and spell-check your assignment. Each question is worth 3 points C ASE 1 A physician asks you to call an amoxicillin prescription into the pharmacy for a patient. 1. After 5 days, the patient feels better and wants to stop the amoxicillin because it is upsetting his stomach. What is your response? You can’t just stop the antibiotic, since the infection is not completely gone, and may return. I would suggest taking food or an antacid with the medication. If they just can’t take it, another antibiotic could possibly be given. You should never stop the medication without notifying the physician and getting medical advice first. 2. Since the patient has suffered an upset stomach, he believes he is allergic to amoxicillin. Would you agree? Explain your response. I don’t agree that it is an allergy. With most medications the number one side effect can be upset stomach. I believe the patient is just suffering a side effect of the antibiotic and would suggest taking it with food. C ASE 2 A patient visits the clinic and it is determined he has a sinus infection as well as a seasonal allergies. The patient’s chart indicates an allergy to penicillin and lists current medications as acebutolol. He is given a prescription for Augmentin. 1. Explain whether Augmentin is a reasonable antibiotic choice in this patient. Augmentin is a combination product of amoxicillin and clavulanate potassium. (calvulanic acid). Amoxicillin is of the extended spectrum penicillins (Beta-Lactams) and clavulanic acid is beta lactamase inhibitor for resistant bacterias 2. The patient has been taking Sudafed and wants to know if he should continue to take it. What is your response? You can continue taking the Sudafed until symptoms improve. C ASE 3 Mr. Cox received a prescription for albuterol. 1. What is the indication for albuterol and how does it act? The irritation could be from the Albuterol in the MDI. It's being deposited on the back of his tongue. This is unavoidable but with proper technique it can be minimized. Tell him to rinse his mouth and spit it out after using the MDI. Albuterol absorbed through the buccal or gastric mucosa has more potential for Beta 1 effects than it does if absorbed through the Respiratory mucosa. Make sure he knows how to use it properly. A Holding Chamber would help. Many people have trouble coordinating the deep breath with squeezing the MDI resulting in it be deposited on the tongue. 2. He is subsequently prescribed beclamethasone. What is the reason for this and how does it act. C ASE 4 Mr. Smith has arthritis and is also experiencing muscle spasms. The physician prescribes an analgesic and a muscle relaxant. 1. What is the likely drug class prescribed for arthritis? How does it act? Mr. Smith mentions him like to have a beer or two after work to help him unwind. Why could alcohol ingestion be dangerous when a patient is taking analgesics? It can increase the chance of internal bleeding. 2. Mr. Smith mentions he took acetaminophen for the arthritis but it did not provide relief. Why is acetaminophen not very effective in treating arthritis? Acetaminophen is a pain reliever however it does not reduce selling. This causes it to not be very effective in treating the pain caused from arthritis because arthritis causes inflammation. Because these drugs have a sedative action the patient should be warned not to drive, operate machinery or perform any other task that requires wakefulness. An overdose of the drugs can put the patient to sleep and may well depress muscle function to the extent that the bladder will not contract normally and urine retention will occur. Also, some drugs will produce a change in the color of the urine. C ASE 5 Mrs. Carleton has been diagnosed with congestive heart failure. Her physician orders digoxin 0.25 mg, two tablets stat and then one tablet daily. 1. Mrs. Carleton asks why she needs to take two tablets now but will only take one daily after that. What is your response? Mrs. Carleton, we start with 2 tablets because we need to build up the medicine in your body as quickly as possible. If we don't start out with a double dose, it make take a week or longer for it to build up in your body enough to help your heart. We have found that after 1 day of the doubled dose, the amount of the medication in your body is enough to have an effect on your heart. We have to be very careful so we don't use too much of the Digoxin. .25 mg is a safe and effective dose for treating your particular problem. 2. Mrs. Carleton wants to know how digoxin will help her heart. What do you tell her? Mrs. Carlton, as you know, you have been diagnosed with congestive heart failure. That makes your heart very weak. It can't squeeze hard enough to push the blood out. You body tries to help out by making your heart beat faster. When you have a fast but weak heart beat, your heart sort of flutters- it's what we call fibrillation. Digoxin increases the strength of each contraction. It helps your heart muscle to squeeze harder to push the blood out. When your heart is able to push the blood out the body sends a message for your heart to not beat fast.
