4. Thyroid
o Diagnosis & Evaluation
Signs and symptoms of hypothyroidism?
-TSH - used primarily for screening and diagnosing hypothyroid and for monitoring replacement therapy in hypothyroid patients
-T4 - Used to monitor thyroid hormone replacement therapy and to screen for thyroid dysfunction
-T3 - Useful in the diagnosis of hyperthyroidism; can also be used to monitor hormone replacement therapy
-TSH low
-T4 normal
-T3 is high = hyperthyroidism
Recheck TSH 6-8 weeks after initiating therapy and after any dosage change;CheckTSH at least once a year after serum TSH is stabilized
Hypothyroidism: Depend on severity.
o Mild: subtle and may go unrecognized
o Moderate to severe:
-Face is pale, puffy, and expressionless.
-Skin cold and dry.
-Hair is brittle and hair loss occurs.
-Slowed Heart rate.
-Patient may complain of lethargy, fatigue, and
-Temperature is lowered & intolerant to cold.
-Thyroid Enlargement may occur if reduced levels of T3 and T4
Mentation may be impaired.
Thyroid
o Diagnosis & Evaluation
Signs and symptoms of hyperthyroidism?
o Elevated Heart rate and strong, and dysrhythmias and angina may develop
oThe CNS is stimulated, resulting is nervousness, insomnia, rapid thought flow, and rapid speech, hyperreflexia, tremors
o Skeletal muscles may weaken and atrophy
o Metabolic rate is raised, resulting in health and skin that is warm and moist
o Feeling Hot + Heat intolerance
o Appetit is increased but fails to match metabolic rate resulting in weight loss
o All of these signs are referred to as thyrotoxicosis
o Also usually present with exophthalmos - bulging of the eyes
6. Thyroid
oTreatment
Treatment of thyroid storm?
Characterized by profound hyperthermia (105 degrees F or higher), severe tachycardia, restlessness, agitation, and tremor.
Unconsciousness, coma, hypotension, and heart failure may ensure.
These symptoms are produced by excessive levels of thyroid hormone
Thyroid crisis can be life threatening and requires immediate treatment.
o High doses of potassium iodide or strong iodine solution are given to suppress thyroid hormone release.
o Methimazole is given to suppress thyroid hormone synthesis
o A beta blocker is given to reduce heart rate
o Additional measures include sedation, cooling, and giving
glucocorticoids and IVF

9. Thyroid
oTreatment
Drug/Food/Supplement interactions with levothyroxine
10. Diabetes
o How to confirm a diagnosis prior to beginning treatment
for hypothyroidism as soon as pregnancy is confirmed
Women already taking thyroid hormone replacement will need to increase dose by 50% max between weeks 4-8 of gestation and the levels will level out by week 16
Methimazole - first line drug of choice (not given to women who are pregnant or breastfeeding)
o Methimazole blocks synthesis of thyroid hormone.
1) Prevents the oxidation of iodine, therefore inhibiting incorporation of iodine into tyrosine.
2) prevents iodinated tyrosine from coupling
Propylthiouracil - preferred treatment for thyroid storm
Beta blockers - help with tachycardia experienced with hyperthyroidism
Absorption of levothyroxine is reduced by food - it should be taken on an empty stomach in the morning, at least 30-60 minutes before breakfast
Drugs that reduce absorption include: H2 receptor blockers, PPIs, Carafate, Questran, Colestid, Maalox/Mylanta, Tums, iron, Mag salts, Xenical
Drugs that accelerate levothyroxine: Phenytoin, Carbamazepine, rifampin, Sertraline, and phenobarbital
Patients taking the following drugs may need to increase their dose of levothyroxine: Warfarin and catecholamines
Levothyroxine can also increase requirements for insulin and digoxin
Fasting plasma glucose >/= 125mg/dl OR Random plasma glucose >/= 200mg/dl plus symptoms of diabetes (polyuria, polydipsia, unexplained weight loss) OR
Oral glucose tolerance test (OGTT): 2-hour plasma glucose >/= 200mg/dl OR
HgbA1C pf 6.5% or greater - (a test that provides an estimate of glycemic control over the previous 2-3 months) is now considered a standard test as well
what time interval should it
To keep A1C below 7%
o <8% is less stringent for those with hx. Of severe hypoglycemia, limited life expectancy, pr advanced microvascular or macrovascular complications
Recommended goal for A1C in the geriatric population is 7.5-8% in older patients with moderate comorbidities and life expectancy less than 10 years
o 8-8.5% for older patients with complex medical issues
Recommendation: A GLP-1 should be considered before starting insulin
Insulin is introduced in Step 3 which includes a 3-drug combination which includes insulin.
A1C of 9% of greater would start at Step 2 with dual med therapy
A1C of 10% or greater or fasting glucose of 300 or greater and is symptomatic would start on combination injectable therapy immediately (Step 4)
Should be monitored every 3 months until value drops to 7% and at least every 6 months thereafter
Metabolic actions of insulin are primarily anabolic - Insulin promotes conservation of energy and buildup of energy stores, such as glycogen and the hormone also promotes cell growth and division
Stimulates cellular transport (uptake) of glucose, amino acids, nucleotides, and potassium
Insulin promotes synthesis of complex organic molecules
In all:Under the influence of insulin - glucose is converted into glycogen, amino acids are assembled into proteins, and fatty acids are incorporated into triglycerides

Ratio of basal insulin to rapid-acting insulin in total daily dose (TDD) of insulin? 24. Know the carbohydrate-to insulin ratio when calculating basal insulin
o Simple calculation (No calculators are allowed and will not be needed) 25. Mechanism of Action
o GLP-1 (Exenatide) (AKA mimetics)
Mechanism of Action -Biguanide (Metformin)
Mechanism of Action
oTZD (Pioglitazone)
Mechanism of Action
oTotal daily insulin dose (TDD) calculation includes basal insulin replacement and bolus insulin replacement. In all: 50% is basal dose and 50% is rapid acting
Daily dose -Total weight of patient in kilograms, multiplied by 0.6.
Ex: 80kg (184) x 0.6 units = 24; this means 24 units of theTDD is the basal insulin dose (long acting) (50%) and the other 24 units of rapid acting bolus/mealtime insulin (50%).
Calculated using the 450 rule for regular insulin and the 500 rule for rapid acting insulin
Ex for rapid acting: 500 divided by 48 = 10.4 (rounded to 10).Therefore, the carb-to-insulin ratio is 1:10
o If the meal is 60 grams of carbs, 60 divided by 10 = 6 units for carb coverage
Lowers blood glucose by slowing gastric acid emptying, stimulating glucose- dependent insulin release, suppressing postprandial glucagon release, and reducing appetite
-Decreases Glucose production by the liver
Decrease insulin resistance and increase glucose uptake by muscle and adipose tissue
-and decrease glucose production by the liver
Enhance the activity of incretins (by inhibiting their breakdown of DPP-4) and thereby increase insulin release, reduce glucagon release
o DPP-4i (Alogliptin) -and decrease hepatic glucose production
29. Mechanism of Action
o Sulfonylureas -Glipizide (Glucotrol)
30. Mechanism of Action
o SGLT2i (Canagliflozin)
31. Which diabetic medication(s) come with a concern of hypoglycemia?
Promote insulin secretion by the pancreases; may also increase tissue response to insulin
-Educate on risk of Hypoglycemia side effect
Increase glucose excretion via the urine by inhibiting SGLT-2 in the kidney tubules
-decreasing glucose levels, and inducing weight loss by caloric loss through the urine
o Sulfonylureas
o Meglitinides (Glinides)
o Thiazolidinediones (Glitazones) - only in the presence of excessive insulin
o Glucagon-like Peptide-1 Receptor Agonists (GLP-1) (Incretin Mimetics)
o Amylin Mimetics
32. ADA's DMTreatment Algorithm
Step 1: At diagnosis, initiate lifestyle changes plus metformin.
Step 2: Continue step 1 & add a 2nd drug (TZD, DPP-4, SGLT-2, or GLP-1).A sulfonylurea or basal insulin should be considered if patient doesn't achieve goal with these drugs.
Step 3: 3-drug combo, including metformin.
Step 4: 3 drug therapy that includes basal insulin fails to reach goals after 3-6 months, proceed to combination injectable insulin. 33. WEEK 6
Methylxanthines
o Who is at risk for toxicity and why?
At risk:Those with liver disease, smokers, caffeine drinkers, those taking certain medications
Why:
Liver disease
- theophylline is metabolized in the liver, and this can cause decreased metabolism which increases drug levels = toxicity
Smokers
- smoking can induce theophylline metabolism which increases drug clearance. Therefore, if the patient stops smoking and does not have the dose of theophylline is not decreased, the patient is at risk for developing toxicity
Caffeine drinkers
- Caffeine can intensify the adverse effects of theophylline on the CNS and the heart. Caffeine can also complete with theophylline for drug-metabolizing enzymes causing theophylline levels to rise. Those taking theophylline should avoid caffeine products and those containing caffeine
Drugs that increase theophylline levelscimetidine and the fluoroquinolone antibiotics (ciprofloxacin).These can elevate plasma levels of theophylline by inhibiting hepatic metabolism.The dosage of theophylline should be reduced when the drug is combined with these agents

o Symptoms associated with each classification of asthma (mild-persistent, moderate-persistent, etc.).
- Nighttime wakening from ages 0-4 years old is normal and cannot be used in the data due to asthma nighttime wakening
Steps 3-5 are more aggressive as our patients get older Pg. 575 in the book for classifications of asthma severity and recommendation for initial treatment
Intermittent: symptoms 2 days a week or less
No nighttime wakening
SABA use is 2 days a week or less
Mild-persistent: symptoms more than 2 days a week but less than daily
Nighttime wakening 1-2 times a month

44. Asthma & COPD o SABA
Why is it important to know the frequency a patient is using their SABA?
If patients are using it more frequently due to symptoms, the provider should be notified so medication changes can take place and the NP can provide adequate asthma relief
45. Asthma & COPD o LABA Examples: Salmeterol, formoterol, oldaterol
Know examples 46. Asthma & COPD o LABA
Benefits of use
Use in COPD
Benefits of use: LABAs are for patients who experience frequent attacks and dosing is done on a fixed, NOT PRN, schedule. For asthma, they must be combined with a glucocorticoid because they are not a first line therapy in asthma (FDA recommends a LABA and glucocorticoid are both contained in the same inhaler to prevent a LABA asthma-associated death - LABA monotherapy in asthma is contraindicated)
47. Asthma & COPD
o Inhaled Corticosteroid (ICS)

LABAs are preferred over SABAs for patients with stable COPD.
LABA can increase the risk for severe asthma attacks and asthma related death; however, this is not a concern for those with COPD
Examples: Budesonide, ciclesonide, beclomethasone
Benefits of use:

of asthma of COPD. Because of their 8 potential for toxicity, they are prescribed only when symptoms cannot be controlled with safer medications (inhaled glucocorticoids or inhaled B2 agonists).Treatment should also be as brief as possible because of the risk for toxicity with duration of use.
For patients with severe, chronic COPD with a primary chronic bronchitis component, the risk for exacerbations may be reduced with this drug.
58. Smoking Cessation
o Nicotine replacement
Patient education needed for various types
How it works:
NRT allows smokers to substitute a pharmaceutical source of nicotine for the nicotine in cigarettes - and then gradually withdraw the replacement nicotine. This is analogous to using methadone to wean addicts of heroin. With gum, lozenges, patches, and inhaler, blood levels of nicotine rise slowly which produce less pleasure than cigarettes but do relieve symptoms of withdrawal. Long-term quit rates are greater with NRT than with placebo (although success rates still remain low).
Patch:
Patches are applied once a day to clean, dry, nonhairy skin of the upper body or upper arm. The site should be changed daily and not reused for at least 1 week.Starting patch is determined based on the number of cigarettes smoked daily.
o Adverse effects:short lived erythema, itching, and burning can occur under the patch. Discontinue patch is there is severe erythema, itching, and edema.
Gum:
Patients should be advised to chew the gum slowly and intermittently for approximately 30 minutes. Rapid chewing can release too much nicotine at one time which
59. Smoking Cessation
results in effects similar to those of excessive smoking (nausea, throat irritation, and hiccups). Foods and beverages can reduce nicotine absorption, so patients should not eat or drink 15 minutes before chewing the gum.
Nasal spray:
The nasal spray increases blood levels of nicotine rapidly like it does with smoking. Some patients are unable to give the spray up because of the similar effects to smoking that it gives. o Adverse effects my most users include rhinitis, sneezing, coughing, watering eyes, and nasal/throat irritation which usually only last a few days. Nicotine nasal spray should be avoided by patients with sinus problems, allergies, and asthma.

63. Bupropion
Recommended
150mg PO daily for 3 days, then 150mg PO twice daily for 7-12 weeks. Treatment with Bupropion should start 1-2 weeks before smoking cessation and should decrease length of treatment use after 7-12 weeks.
Bupropion was the first non-nicotine drug approved as an aid to smoking cessation. It reduced the urge to smoke and reduces some symptoms of nicotine withdrawal (irritability and anxiety).
64. Tuberculosis (TB)
o What constitutes drug-resistantTB
65. Tuberculosis (TB)
Occurs when TB bacteria become resistant to the drugs used to treat the disease and includes multidrug-resistant (MDR TB) and extensively drug-resistant (XDR TB).
MDR TB is caused by bacteria that are resistant to both isoniazid and rifampin, two potent TB drugs
XDR TB infection is less common and is caused by resistance to isoniazid and rifampin as well as any fluoroquinolone and at least one of three second-line medications.These patients have a greatly decreased number of treatment options and a higher risk of death
