Individuals with bulimia are usually within normal weight range lanoxin 0.25 mg on line, some a few pounds underweight effective lanoxin 0.25 mg, some a few pounds overweight. Obsession with body image and appearance is a predominant feature of this disorder. Individuals with bulimia display undue concern with sexual attractiveness and how they will appear to others. Excessive vomiting may lead to problems with dehydration and electrolyte imbalance. Genetics: A hereditary predisposition to eating disorders has been hypothesized on the basis of family histories and an apparent association with other disorders for which the likelihood of genetic inﬂuences exist. Neuroendocrine Abnormalities: Some speculation has occurred regarding a primary hypothalamic dysfunction in anorexia nervosa. Studies consistent with this theory have revealed elevated cerebrospinal ﬂuid cortisol levels and a possible impairment of dopaminergic regulation in individuals with anorexia (Halmi, 2008). Neurochemical Inﬂuences: Neurochemical inﬂuences in bulimia may be associated with the neurotransmitters serotonin and norepinephrine. Some studies have found high levels of endogenous opioids in the spinal ﬂuid of cli- ents with anorexia, promoting the speculation that these chemicals may contribute to denial of hunger (Sadock & Sadock, 2007). Some of these individuals have been shown to gain weight when given naloxone, an opioid antagonist. Psychodynamic Theory: The psychodynamic theory sug- gests that behaviors associated with eating disorders reﬂect a developmental arrest in the very early years of childhood caused by disturbances in mother-infant interactions. The tasks of trust, autonomy, and separation-individuation go unfulﬁlled, and the individual remains in the depen- dent position. The problem is compounded when the mother responds to the child’s physical and emotional needs with food. Manifestations include a disturbance in body identity and a distortion in body image. When events occur that threaten the vulner- able ego, feelings emerge of lack of control over one’s body (self). Behaviors associated with food and eating provide feelings of control over one’s life. Family Dynamics: This theory proposes that the issue of control becomes the overriding factor in the family of the individual with an eating disorder. These families often consist of a passive father, a domineering mother, and an overly dependent child. A high value is placed on perfec- tionism in this family, and the child feels he or she must satisfy these standards. Parental criticism promotes an increase in obsessive and perfectionistic behavior on the Eating Disorders ● 221 part of the child, who continues to seek love, approval, and recognition. In adolescence, these distorted eating patterns may represent a rebellion against the parents, viewed by the child as a means of gaining and remaining in control. The symptoms are often triggered by a stressor that the adolescent perceives as a loss of con- trol in some aspect of his or her life. These guidelines, which were released by the National Heart, Lung, and Blood Institute in July 1998, markedly increased the number of Americans considered to be overweight. Obesity is known to contribute to a number of health prob- lems, including hyperlipidemia, diabetes mellitus, osteoarthritis, and increased workload on the heart and lungs. Genetics: Genetics have been implicated in the develop- ment of obesity in that 80% of offspring of two obese parents are obese (Halmi, 2008). This hypothesis has also been supported by studies of twins reared by normal and overweight parents. Physical Factors: Overeating and/or obesity has also been associated with lesions in the appetite and satiety centers of the hypothalamus, hypothyroidism, decreased insulin production in diabetes mellitus, and increased cortisone production in Cushing’s disease. Lifestyle Factors: On a more basic level, obesity can be viewed as the ingestion of a greater number of calories than are expended. Weight gain occurs when caloric in- take exceeds caloric output in terms of basal metabolism and physical activity. Psychoanalytical Theory: This theory suggests that obe- sity is the result of unresolved dependency needs, with the individual being ﬁxed in the oral stage of psychosex- ual development. The symptoms of obesity are viewed as depressive equivalents, attempts to regain “lost” or frus- trated nurturance and care. Common Nursing Diagnoses and Interventions for Anorexia and Bulimia (Interventions are applicable to various health-care settings, such as inpatient and partial hospitalization, community outpatient clinic, home health, and private practice. Possible Etiologies (“related to”) [Refusal to eat] [Ingestion of large amounts of food, followed by self-induced vomiting] [Abuse of laxatives, diuretics, and/or diet pills] [Physical exertion in excess of energy produced through caloric intake] Deﬁning Characteristics (“evidenced by”) [Loss of 15% of expected body weight (anorexia nervosa)] Pale mucous membranes Poor muscle tone Excessive loss of hair [or increased growth of hair on body (lanugo)] [Amenorrhea] [Poor skin turgor] [Electrolyte imbalances] [Hypothermia] [Bradycardia] [Hypotension] [Cardiac irregularities] [Edema] Eating Disorders ● 223 Goals/Objectives Short-term Goal Client will gain lbs per week (amount to be established by client, nurse, and dietitian). Long-term Goal By discharge from treatment, client will exhibit no signs or symptoms of malnutrition. If client is unable or unwilling to maintain adequate oral in- take, physician may order a liquid diet to be administered via nasogastric tube.
Nurses encounter household measurements when providing home healthcare services and when determining a patient’s fluid intake and output in the hospital setting purchase lanoxin 0.25mg mastercard. Nurses also use pounds when calculating a dose that is based on a patient’s weight 0.25 mg lanoxin visa. Patients should use measuring spoons for medication administration at home and avoid using tableware. Patients are usually more comfortable self-administering medication if the dose is in household measurements. Therefore, a nurse must be able to convert household measure- ments to metric measurements. The nurse must convert that to milliliters (mL) or cubic centimeters (cc) in order to record the intake volume in the patient’s fluid input and output chart. Commonly used conversion factors for household measurement and metric measurement. For example, if the dose is in milligrams and the prescriber’s medication order specifies grams, you’ll need to convert grams to milligrams before calculating the dose. Converting from one metric unit to another metric unit isn’t difficult if you remember these three rules. Determine if the desired measurement is larger or smaller than the given measurement. Remember that gram, liter, and meter are larger units and milligram, milliliter, and millimeter are smaller units. If you are converting from a smaller unit to a larger unit, then you multi- ply by moving the decimal three places to the left. If you are converting from a larger unit to a smaller unit, then you divide by moving the decimal three places to the right. Therefore, you divide by moving the decimal three places to the left, as shown here. Therefore, you multiply by moving the decimal three places to the right, as shown here. This is also the easiest conversion because one milliliter (mL) is equal to 1 cubic centimeter (cc). Always place a zero to the left of the decimal when the quantity is not a whole number. There, you’ll use a teaspoon, tablespoon, or cups mea- sured in ounces to administer medication. When converting from milliliters or cubic centimeters to ounces, divide by 30, as shown here: [Remember 30 cc (30 mL) = 1 oz. For example, the medication prescription is for a 15-mg tablet of Inderal and the hospital has on hand a 15-mg tablet of Inderal. In the real world, the dose specified in the medical prescription may not be available. The hospital might have 10-mg tablets of Inderal and not the 15-mg tablets prescribed. Instead of asking the prescriber to change the medication order, the nurse calculates the proper medication to give the patient based on the medication order and the dose that is on hand. When applying either method, make sure that all the terms are in the same units before calculating the desired dose. For example, the medication order might be in grams and the dose on hand might be in milligrams. The nurse will need to convert the grams to milligrams before calculating the desired dose to give. D × V = A Quantity (Desired dose divided by dose you have H multiplied by vehicle of drug you have equals the amount calculated to be given to the patient) D = desired dose H = dose you have V = vehicle you have (tablets or liquids) A = amount calculated to be given to the patient Ratio and proportion method H V :: D x Means Extremes H is the drug on hand (available) V is the vehicle or drug form (tablet, capsule, liquid) D is the desired dose (as prescribed) x is the unknown amount to give, and :: stands for “as” or “equal to. Example: Give 500 mg of ampicillin sodium by mouth when the dose on hand is in capsules containing 250 mg. For example, use mg following a value in the formula if the value is in milligrams. Parenteral Medications Parenteral medication is a medication that is administered to a patient by an injection or by an intravenous flow. The dose for an injection is calculated using the formula method or the ratio-proportion method that is described previously in this chapter. The nurse must calculate the number of milliliters that should be administered to the patient. The intravenous order directs the nurse to administer a specific vol- ume of fluid to the patient over a specific time period. In order the calculate the drip rate you need to know: • The volume of fluid that is to be infused. This is found in the medication order in milliliters (mL) or cubic centimeters (cc). It is important to remember that although we use milliliters in the following examples, you can substitute cubic centi- meters (cc) for milliliters (mL) if cc is specified in the order.
