Her 20-year-old son has asthma and she has tried his salbutamol inhaler on two or three occasions but found it to be of no real benefit buy 80 mg micardis mastercard. She has tested herself on her son’s peak flow meter at home and she has obtained values of about 100 L/min 40 mg micardis visa. On direct question- ing she says that the shortness of breath tends to be worse on lying down but there are no other particular precipitating factors or variations through the day. There is a generalized wheeze heard all over the chest but no other abnormalities. It is similar in both inspiration and expiration as shown in the flow volume loop (Fig. The spirometry trace of volume against time in such cases shows a straight line of the same reduced flow right up to the vital capacity. On examination, this airway narrowing is likely to produce a single monophonic wheeze which may be heard over a wide area of the chest. Differential diagnosis of rigid large-airway obstruction The situation may easily be confused with asthma if the peak flow and the wheezing are accepted uncritically. The wheezing in asthma comes from many narrowed airways of different calibre and mass, and the wheezes are often described as polyphonic. The fixed flow in inspiration and expiration in this case suggest a rigid large-airway nar- rowing.

The kidneys regulate the sodium balance by retaining urine when the sodium concentration is low and excreting urine when the sodium concentration is high buy 20 mg micardis free shipping. Most excess sodium is excreted in urine although sodium also leaves the patient as perspira- tion and in feces discount micardis 80mg visa. The serum sodium level, which is the ratio of sodium to water, is the indicator of the sodium level in a patient’s body. A patient’s serum sodium level moves out of the normal range when the patient is retaining too much or too little water, has a high or low concentrations of sodium, or a combination of both. A patient is hypernatremic when there is a high concen- tration of sodium and hyponatremic when there is a low concentration of sodium. Hypernatremia Hypernatremia occurs when the patient’s serum sodium is greater than 145 mEq/L. This happens for one of two reasons: The patient’s sodium concentration has increased while the volume of water remains unchanged or the patient’s water volume has decreased while the sodium concentration remains unchanged. Regardless of what happened, the patient experiences hyperosmolality, which is a higher-than-normal concentration of sodium. This causes water to shift out of cells and into extracellular space resulting in cellular dehydration. However, a patient whose consciousness is impaired or who cannot swallow, such as a frail elderly patient, is at risk for hypernatremia. These are: • Agitation • Restlessness • Weakness • Seizures • Twitching • Coma • Intense thirst • Dry swollen tongue • Edematous (swollen) extremities The nurse should educate the patient to: • Avoid foods rich in sodium such as canned foods, lunch meats, ham, pork, pickles, potato chips, and pretzels. Hyponatremia Hyponatremia occurs when the patient’s serum sodium is less than 135 mEq/L.
