Receiver imbalance

Although truckers pay road and fuel taxes, it pays only a small fraction of the cost of safety inspections and road damage from trucking. The taxes paid/benefits received imbalance has only grown through the years. 

As part of the preadministration assessment for a patient receiving a drug for nausea and vomiting, the nurse documents the number of times the patient has vomited and the approximate amount of fluid lost. Before starting therapy, the nurse takes vital signs and assesses for signs of fluid and electrolyte imbalances (see Chap. 58). 

MANAGING FLUID VOLUM E DEFICIT. The patient receiving a diuretic is observed for dehydration and electrolyte imbalances. A fluid volume deficit is most likely to occur if the patient fails to drink a sufficient amount of fluid. This is especially true in the elderly or confused patient. To prevent a fluid volume deficit, the nurse encourages patients to drink adequate oral fluids (up to 3000 mL/d, unless contraindicated). 

The most common imbalances are a loss of potassium and water. Other electrolytes, namely magnesium, sodium, and chlorides, are also lost. When too much potassium is lost, hypokalemia (low blood potassium) occurs (see Home Care Checklist Preventing Potassium Imbalances). In certain patients, such as those also receiving a digitalis glycoside or those who currently have a cardiac arrhythmia, hypokalemia has the potential to create a mo re serious arrhythmia Hypokalemia is... 

Whether a fluid or electrolyte imbalance occurs depends on the amount of fluid and electrolytes lost and the ability of the individual to replace them. For example, if a patient receiving a diuretic eats poorly and does not drink extra fluids, an electrolyte and water imbalance is likely to occur, especially during initial therapy with the drug. However, even when a patient drinks adequate amounts of fluid and eats a balanced diet, an electrolyte imbalance may still occur and require electrolyte replacement (see Chapter 58 and Display 58-2 for additional discussion of fluid and electrolyte imbalances). 

The nurse must closely observe patients receiving a potassium-sparing diuretic for signs of hyperkalemia (see Display 46-1), a serious and potentially fatal electrolyte imbalance The patient is closely monitored for hypokalemia during loop or thiazide diuretic therapy. A supplemental potassium supplement may be prescribed to prevent hypokalemia. The primary health care provider may also encourage the patient to include...

Severe disease is defined as the presence of complications of colitis, such as sepsis, volume depletion, electrolyte imbalance, hypotension, paralytic ileus, and toxic megacolon. Patients with signs of severe disease should receive oral vancomycin as initial therapy. Surgical intervention may be indicated and lifesaving, particularly in cases complicated by toxic megacolon or colonic perforation. 

After neurotransmitter molecules have influenced the firing of a receiving neuron (more technically called a postsynaptic neuron), some of them are destroyed by enzymes in the synaptic cleft (the synapse), some are reabsorbed by the sending presynaptic neuron in a process that is called reuptake , and the rest remain in the space between the two neurons. The chemical-imbalance hypothesis is that there is not enough serotonin, norepinephrine and/or dopamine in the synapses of the brain. This is more specifically termed the monoamine theory of depression, because both serotonin and norepinephrine belong to the class of neurotransmitters called monoamines. 

In the 12-month safety study (N = 805, 2 1 (alvimopan placebo) randomization) 3 at 0.5 mg twice daily was well tolerated and showed evidence of sustained efficacy when taken continuously for 12 months by patients with nonmalignant pain requiring sustained treatment with opioids. However, unexpectedly, there were more reports of myocardial infarctions in patients treated with 3 at 0.5 mg twice daily compared with placebo-treated patients. The majority of myocardial infarctions occurred between 1 and 4 months after initiation of treatment. This imbalance has not been observed in other studies of 3, including studies in patients undergoing bowel resection surgery who received 3 at 12 mg twice daily for up to 7 days. A causal relationship with 3 has not been established [29]. 

Clinicians should consider the precipitating cause of the cardiac arrest, such as MI, electrolyte imbalance, or primary arrhythmia. Prearrest status should be carefully reviewed, particularly if the patient was receiving drug therapy. 

Electrolyte imbalance Electrolyte imbalance may occur, especially in patients receiving high doses with restricted salt intake. Perform periodic determinations of serum electrolytes. 

Hospitalized treatment is usually 5 to 14 days. The first aim of inpatient treatment for a bulimic patient should be to stop the bingeing and purging behavior. This not only helps to correct electrolyte imbalances and dehydration but is also the first step for reestablishing normal eating behavior. The bulimic patient should receive sufficient calories to maintain weight within a normal range. Access to bathrooms should be restricted and supervised to prevent surreptitious vomiting.
