Answer:
Explanation:
The bone is being destroyed by osteoclasts faster than it can be rebuilt by osteoblasts. A lot of factors can contribute but osteoporosis affects mostly post-menopausal women due to their hormone levels
Answer:
Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:
- Oxygenation (PaO₂): hypoxemia
- pH: acidosis
- PaCO₂: Hypercapnia
- HCO₃⁻: normal
whose interpretation is: <u>respiratory acidosis</u>.
Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.
Explanation:
Respiratory acidosis is due to a failure in the breathing process that produces <u>hypoventilation</u>, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.
- <u><em>Acidosis</em></u><em> is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in </em><em>pH</em><em> below 7.35, with no change in bicarbonate content.</em>
- <u><em>Hypoxemia</em></u><em> is the decrease of PaO₂ below 60 mmHg.</em>
- <u><em>Hypercapnia</em></u><em> is the increase of PaCO₂ in ABG above 45 mmHg.</em>
- <em>Normal </em><em>bicarbonate</em><em> </em><em>(HCO₃⁻) </em><em>values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.</em>
<u>Hypercapnia mainly affects the nervous system</u>, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.
Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
Symptoms of Creutzfeldt-Jakob disease (CJD) can resemble those of other dementia-like brain disorders, such as Alzheimer's. But Creutzfeldt-Jakob disease usually progresses much more rapidly.
