metoprolol (Lopressor, Toprol XL)
Class: Beta1-selective adrenergic blocking agents Use: hypertension, angina, and some cardiac arrhythmias Notes on Action: have an advantage over the nonselective beta-blockers in some cases. Because they do not usually block beta2-receptor sites, they do not block the sympathetic bronchodilation that is so important for patients with lung diseases or allergic rhinitis. Consequently, these drugs are preferred for patients who smoke or who have asthma, any other obstructive pulmonary disease, or seasonal or allergic rhinitis.

[2] It acts by inhibiting the enzyme thyroid peroxidase, which usually functions to convert iodide to iodine molecule and incorporate the iodine molecule into amino acid tyrosine.
naloxone (Evzio)
Class: narcotic antagonists The narcotic antagonists block opioid receptors and reverse the effects of opioids, including respiratory depression, sedation, psychotomimetic effects, and hypotension
dopamine (generic)
Class: naturally occurring catecholamine Uses: treatment for shock Action: It stimulates the heart and blood pressure but also causes a renal and splanchnic arteriole dilation that increases blood flow to the kidneys, preventing the diminished renal blood supply and possible renal shutdown that can occur with epinephrine or norepinephrine, which are also naturally occurring catecholamines that interact with both alpha- and beta-adrenergic receptors and are used for the treatment of shock and to stimulate the body after cardiac arrest and for immediate relief of anaphylaxis
sodium iodide (generic radioactive iodine)
Class: norganic compounds known as alkali metal iodides Use: use in performance of the radioactive iodide (RAI) uptake test to evaluate thyroid function. Action:taken by mouth, readily absorbed into the body and is trapped within the thyroid gland. The trappedsodium iodideI 131 irradiates the thyroid gland thereby damaging it. As a result, the activity of the thyroid gland (that is, the production and release of thyroid hormone) is reduced

Uses and benefits of low molecular weight heparin
It inhibits thrombus and clot formation by blocking factors Xa and IIa. Because of the size and nature of the molecules, these drugs do not greatly affect thrombin, clotting, or the PT; therefore, they cause fewer systemic adverse effects. They also have been found to block angiogenesis, the process that allows cancer cells to develop new blood vessels. These drugs are indicated for specific uses in the prevention of clots and emboli formation after certain surgeries or prolonged bed rest. Caution must be used to avoid combining these drugs with standard heparin therapy; serious bleeding episodes and deaths have been reported when this combination was used.
The black box warning associated with warfarin concerns its risk of causing what condition?
Major or fatal bleeding
Administration and client teaching for methylphenidate hydrochloride (Ritalin)
Methylphenidate hydrochloride otherwise known as Ritalin is a central nervous stimulant used to treat attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is best to take this medication in the morning, to prevent sleep difficulties. Some common side effects of Ritalin are skin rashes, nausea, insomnia, headache and blurred vision. This medication can be associated with sudden cardiac death, so it will be important to do heart tests to determine what the normal function of your heart is like to have something to compare it to just in case something was to go wrong. Notify your doctor if you are experiencing any heart issues such as chest pain or irregular heartbeat. Physical and psychological dependence can occur when taking this drug. It is important to notify your doctor of any alcohol or drug problems you have had previously. It is also important to notify your doctor if you are taking MAOIs. Ritalin and MAOIs together are an undesired combination with potentially serious side effects and should be avoided.

Long Acting Insulin Onset and Peak Times:
Onset 2 hours
Transition from IV coagulation therapy to oral route
Oral anticoagulant Warfarin is prescribed, the patient is still receiving IV heparin. This is done to allow the time for blood levels of warfarin to rise so when the heparin is discontinued the therapeutic anticoagulation levels of warfarin will be achieved. This is done for 5 days until the INR is above 2. The dose of the oral drug is the initial dose amount and then the prescriber uses the PT/INR levels to figure out which is the next dosage for warfarin.

Stage 2 of Anesthesia
The excitement stage, is a period of excitement and often combative behavior with many signs of sympathetic stimulation (e.g., tachycardia, increased respirations, blood pressure changes).
Adverse effects of statins:
The most common adverse effects associated with these drugs reflect their effects on the GI system: flatulence, abdominal pain, cramps, nausea, vomiting, and constipation. CNS effects can include headache, dizziness, blurred vision, insomnia, fatigue, and cataract development and may reflect changes in the cell membrane and synthesis of cholesterol. Increased concentrations of liver enzymes commonly occur, and acute liver failure has been reported with the use of atorvastatin and Fluvastatin. Rosuvastatin is associated with increased occurrence of rhabdomyolysis in Asian American patients

The most frequently seen adverse effects associated with these drugs relate to the associated CNS depression: drowsiness, fatigue, weakness, confusion, headache, and insomnia. Gastrointestinal (GI) disturbances, which may be linked to CNS depression of the parasympathetic reflexes, include nausea, dry mouth, anorexia, and constipation. In addition, hypotension and arrhythmias may occur, again as a result of depression of normal reflex arcs. Urinary frequency, enuresis, and feelings of urinary urgency reportedly may occur. Chlorzoxazone may discolor the urine, becoming orange to purplish-red when metabolized and excreted. Patients should be warned about this effect to prevent any fears of blood in the urine. Tizanidine has been associated with liver toxicity and hypotension in some patients.

These drugs are indicated as adjuncts with diet and exercise for the treatment of increased cholesterol and LDL levels that are unresponsive to dietary restrictions alone.
Client teaching r/t glyburide
They are indicated as an adjunct to diet and exercise to lower blood glucose levels in type 2 diabetes mellitus. They have the off-label use of being an adjunct to insulin and metformin to improve glucose control in type 2 diabetics. These drugs are not for use during pregnancy. The most common adverse effects related to the sulfonylureas are hypoglycemia (caused by an imbalance in levels of glucose and insulin) and GI distress Care should be taken with any drug that acidifies the urine because excretion of the sulfonylurea may be decreased. Caution should also be used with beta-blockers Caution must also be used with many herbal therapies that could alter blood glucose levels. Adverse Effects: GI discomfort, anorexia, heartburn, vomiting, nausea, hypoglycemia.

Use: narcotic agonists-antagonists stimulate certain opioid receptors but block other such receptors. These drugs, which have less abuse potential than the pure narcotic agonists, exert a similar analgesic effect as morphine. Like morphine, they may cause sedation, respiratory depression, and constipation. They have also been associated with more psychotic-like reactions, and they may even induce a withdrawal syndrome in patients who have been taking narcotics for a long period.
Ezetimibe (Zetia)
Uses: It's used to treat high blood cholesterol. Action: Ezetimibe inhibits the absorption of cholesterol from the small intestine and decreases the amount of cholesterol normally available to liver cells. This leads them to absorb more cholesterol from circulation and thus causes lowering levels of circulating cholesterol.

Client teaching r/t eye drop administration:
Wash hands thoroughly before administering; do not touch the dropper to the patient's eye or to any other surface. Have the patient tilt the head backward or lie down, and have the patient stare upward. Gently grasp the lower eyelid and pull the eyelid away from the eyeball; instill drops into the pouch formed by the eyelid. Release the lid slowly; have the patient close the eye and look downward. Apply gentle pressure to the inside corner of the eye for 3 to 5 minutes to retard drainage. Do not rub the eyes; do not rinse the eyedropper. Do not use eye drops that have changed color; if more than one type of eye drop is used, wait at least 5 minutes between administrations.

Effects of Anesthesia on Adults
· Adults require a considerable amount of teaching and support when receiving anesthetics, including what will happen, what they will feel, how it will feel when they recover, and the approximate time to recovery. · Adults should be monitored closely until fully recovered from general anesthetics and should be cautioned to prevent injury when receiving local anesthetics. It is important to remember to reassure and talk to adults who may be aware of their surroundings yet unable to speak. · Most of the general anesthetics are not recommended for use during pregnancy because of the potential risk to the fetus. Short-onset and local anesthetics are frequently used at delivery. Use of a regional or other local anesthetic is usually preferred if surgery is needed during pregnancy. During lactation, it is recommended that the mother wait 4 to 6 hours to feed the baby after the anesthetic is used
Effects of Anesthesia on Older Adults
· Older patients are more likely to experience the adverse effects associated with these drugs, including CNS, CV, and dermatological effects. Thinner skin and the possibility of decreased perfusion to the skin make them especially susceptible to skin breakdown during immobility. Because older patients often also have renal or hepatic impairment, they are also more likely to have toxic levels of the drug related to changes in metabolism and excretion. The older patient should have safety measures in effect, such as side rails, a call light, and assistance to ambulate; special efforts to provide skin care to prevent skin breakdown are especially important with older skin. The older patient may require longer monitoring and regular orienting and reassuring. After general anesthesia, it is important to promote vigorous pulmonary toilet to decrease the risk of pneumonia.
Bupivacaine (Marcaine, Sensorcaine)
· Use: Bupivacaine injection is used to numb an area of your body during or after surgery or other procedures, childbirth, or dental work. This medicine is also used to numb your shoulder after surgery for up to 72 hours. It is a local anesthetic. · On set 5-20 min · Duration: 2-7 hr · Administration routes: local, epidural, dental, caudal, subarachnoid, sympathetic, retrobulbar -Don't use Bier block, deaths have occurred
Lidocaine (Dilocaine, Lidoderm, etc.)
· Use: Lidocaine is a local anesthetic (numbing medication) that is used to numb an area of your body to help reduce pain or discomfort caused by invasive medical procedures such as surgery, needle punctures, or insertion of a catheter or breathing tube. · On set 5-15 min · Duration 30-90 min · Route: caudal, epidural, spinal, cervical, dental, skin, mucous membrane, topical patch Special consideration: short-acting, preferred for short procedures, dangerous if absorbed systemically
Pancuronium (generic)
· Use: surgical procedures, mechanical ventilation · Special consideration: vagolytic effect, associated with increased heart-rate; long term use for mechanical ventilation, monitor for prolonged adverse effects
Effects of anesthesia on Children
· greater risk for complications after anesthesia—laryngospasm, bronchospasm, aspiration, and even death. They require careful monitoring and support, and the anesthetist needs to be skilled at calculating dosage and balance during the procedure. Propofol is widely used for diagnostic tests and short procedures in children older than 3 years of age because of its rapid onset and metabolism and generally smooth recovery. Sevoflurane has a minimal impact on intracranial pressure and allows a rapid induction and recovery with minimal sympathetic reaction. It is still quite expensive, however, which may limit its use. The dosage of anesthetics may need to be higher in children, and that factor will be considered by the anesthetist. · Nursing care after general anesthesia should include support and reassurance; assessment of the child for any skin breakdown related to immobility; and safety precautions until full recovery has occurred. · Local anesthetics are used in children in much the same way that they are used in adults. · Bupivacaine and tetracaine do not have established doses for children younger than 12 years of age. Benzocaine should not be used in children younger than 1 year of age. · When topically applying a local anesthetic, it is important to remember that there is greater risk of systemic absorption and toxicity with infants. · Tight diapers can act like occlusive dressings and increase systemic absorption. Children need to be cautioned not to bite themselves when receiving dental anesthesia.
