Your world has no doubt changed a great deal over the years 10 mg reglan amex, but you probably still look through many of the same old lenses discount 10 mg reglan with mastercard. As a kid, she was harshly criticized when she wasn’t perfect, so the lens helped her avoid some of that criticism. But today, as an adult, her perfectionistic life-lens causes her anxiety, stress, and even depression when she fails. Hannah completes the Then and Now Exercise in Worksheet 7-12 in order to help her under- stand how her past experiences cause her to overreact to current triggers. Worksheet 7-12 Hannah’s Then and Now Exercise Problematic Life-Lens Childhood Image(s) Current Triggers Perfectionistic: My mother would scream If I get a snag or a run in I feel like I must do at me if I got my clothes my hose, I freak.

Tragically, one beautiful fall day a highly disturbed classmate brought a gun to school and shot three students. Subsequently, Adam suffered from nightmares, experienced intrusive images of the event, and was easily startled. His vulnerable life-lens is activated by events only superficially similar to the original trauma. Adam completes the Then and Now Exercise in Worksheet 7-13 in order to help him understand how his past experiences contribute to his current responses.

The pointing at me is burned cuts me off in traffic, I feel world feels very deeply into my brain. Take some time to fill out the Then and Now Exercise (see Worksheet 7-14) for each problematic life-lens that you identified in Worksheet 7-1 earlier in this chap- ter. Whenever one of your problematic life-lenses is activated, refer back to this form in order to remind yourself that your feelings and reactions today have more to do with yesteryear than with your current reality. In the left-hand column, write down one of the problematic life-lenses that you rated as 3 or above on your Problematic Life-Lens Questionnaire (see Worksheet 7-1). Also include a brief definition of the life-lens based on your reflections from Worksheet 7-2. Reflect on your childhood and, in the middle column, record any memories or images that probably had something to do with the development of your life-lens. Be on the lookout for events that trigger your life-lens, and write those events down in the right-hand column as they occur. Because each lens often has multiple images and a variety of triggers, you should fill out a sep- arate form for each problematic life-lens. And whenever your problematic life-lens is triggered, review this Then and Now Exercise as a reminder of what your reaction is actually all about. For almost any problematic life-lens, you need to employ an array of strategies in order to feel significant benefit. Don’t expect a single exercise to “cure” you, and always consider professional help if your own efforts don’t take you far enough. After you complete the exercise, take some time to reflect on what you’ve learned about yourself and your feelings, and record your reflections in Worksheet 7-15. Worksheet 7-15 My Reflections Tallying up costs and benefits of current life-lenses The process of changing life-lenses stirs up some anxiety in most people. That’s because people believe (whether consciously or unconsciously) that life-lenses either protect or benefit them in some important ways. For example, if you have a vulnerable life-lens, you probably think that seeing the world as dangerous helps you avoid harm. Or if you possess a dependency life-lens, you likely think that it guides you to find the help from others that you truly need. Only when you fully believe that your life- lenses cause you more harm than good do you have the motivation to change them. Cameron rarely sets limits on himself or others and doesn’t think he should have to. His high intelligence and easy-going personality have enabled him to get by — until recently. Hangovers often cause him to miss classes, and his grades, pre- viously hovering just above passing, sink into the failure zone. Alarmed, his parents encourage him to see someone at the Student Mental Health Center. After discovering that Cameron looks through an under-control life-lens, his therapist suggests that he fill out a Cost/Benefit Analysis of his life-lens. Because patients often downplay the benefits of their life-lenses when they’re in therapy, his therapist suggests that he first ponder the advantages of his life-lens (see Worksheet 7-16). Chapter 7: Correcting Your Life-Lenses: A New Vision 111 Worksheet 7-16 Cameron’s Cost/Benefit Analysis (Part I) Life-Lens: Under-control. Cameron doesn’t have much trouble figuring out benefits for his problematic life-lens.

Fat-soluble vitamins Fat-soluble vitamins are absorbed by the intestinal tract following the same metabolism as used with fat. Any condition that interferes with the absorption of fats will also interfere with the absorption of fat-soluble vitamins. Fat-soluble vitamins are stored in the liver, fatty tissues and muscle and remain in the body longer than water-soluble vitamins. Vitamin A Vitamin A (Acon, Aquasol) helps to maintain epithelial tissue, eyes, hair and bone growth. It is important to keep in mind that Vitamin A is stored in the liver for up to two years, which can result in inadvertent toxicity if the patient is administered large doses of Vitamin A. Vitamin D Vitamin D, absorbed in the small intestine with the assistance of bile salts, is necessary for the intestines to absorb calcium. Contraindications Mineral oil, cholestyramine, alcohol, and antilipemic drugs decrease the absorption of vitamin A. Contraindications Hypercalcemia, hypervitaminosis D, or renal osteodys- trophy with hyperphosphatemia. Use with caution in patients with arteriosclerosis, hyperphosphatemia, hypersensitivity to vitamin D, and renal or cardiac impairment. There are two forms of Vitamin D: D2, called ergocalciferol; and D3, called cholecalciferol. D3 is the natural form of Vitamin D that is produced in the skin by ultraviolet sunlight. Once absorbed, Vitamin D is converted into calcifediol in the liver and then converted to an activated form of calcifediol in the kidneys. When serum levels of calcium are low, more Vitamin D is used to create the active form of calcifediol. Low serum levels of calcium cause a decrease in the creation of the active form of calcifediol. Excess Vitamin D is then excreted in bile and a small amount is excreted in urine. Vitamin E Vitamin E protects the heart and arteries and cellular components from being oxidized and prevents red blood cells from hemolysis (rupture). Seventy-five percent of excess Vitamin E is excreted in the bile and the remainder is excreted in urine. Iron and vitamin E should not be taken together because iron can interfere with the body’s absorption and use of vitamin E. There are four forms of Vitamin K: K1 (phytonadione), which is the active form; K2 (menaquinone), which is synthesized by intestinal flora, but not commercially available; K3 (mena- dione) and K4 (menadiol), both of which are produced synthetically. Vitamin K is absorbed in the intestines and is stored in the liver and in other tissues. Water-soluble vitamins Water-soluble vitamins are also known as the B Complex because it was origi- nally considered as one vitamin. Unlike fat-soluble vitamins, vitamin C is not stored in the body and is excreted in urine. However, high serum levels of vitamin C can result from excessive doses and be excreted without any change. Maintenance 45–60 mg/d Pregnancy category C Deficiency conditions Prevents and treats C deficiency (scurvy); increases wound healing; for burns; sickle cell crisis; deep vein thrombosis; Megavitamin therapy (massive doses) of vitamins are not recommended as it can cause toxicity. Side effects Headaches, fatigue, drowsiness, nausea, heartburn, vomiting, diarrhea. Vitamin C with aspirin or sulfonamides may cause crystal formation in the urine (crystalluria); it can also cause a false-negative occult (blood) stool result and false-positive sugar result in the urine when tested by the Clinitest method. B2 is used to manage dermatologic prob- lems, such as scaly dermatitis, cracked corners of the mouth, inflammation of the skin and tongue. Vitamin B Complex Dose for treatment Thiamine: 30–60 mg/d of deficiency Riboflavin: 5–25 mg/d Prophylactic: 3 mg/d Nicotinic acid or niacin: Prevention: 5–20 mg/d Deficit: 50–100 mg/d Pellagra: 300–500 mg in 3 divided doses Hyperlipidemia: 1–2 g/d in 3 divided doses Pyridoxine: 25–100 mg/d Isoniazid therapy prophylaxis: 20–25 mg/d Peripheral neuritis: 50–200 mg/d Maintenance Thiamine: Male 1. Folic acid is found in leafy green vegetables, yellow fruits and vegetables, yeast, and meat and is absorbed in the small intestine. The active form of folic acid—called folate—circulates to all tissues in the body. A third of folate is stored in the liver and the remainder is stored in other tissues. Patients taking phenytoin (Dilantin) for seizures should be cautious about taking folic acid because it can increase the risk of seizures. Chronic alcoholism, poor nutrition, pregnancy, and diseases that disrupts absorption by the small intestine can lead to an inadequate amount of folic acid.
