Week 5 check your understanding
A patient, who is 8 months pregnant, has developed eclampsia and is receiving intravenous magnesium sulfate to prevent seizures. To determine if her infusion rate is too high, you should regularly
Check the patellar reflex; if it becomes weak or absent, her infusion rate probably is too high and she is at risk for respiratory depression or cardiac arrest
COPD leads to a barrel chest, because it causes
air trapping
Viral pneumonia is characterized by
A dry cough
Early manifestations of a developing metabolic acidosis include
A headache
Signs and symptoms of extracellular fluid volume excess include
Bounding pulse
How do clinical conditions that increase vascular permeability cause edema
By allowing protein plans proteins to leak into interstitial fluid, which draws excess fluid by increasing the interstitial fluid osmotic pressure
Clinical manifestations of severe symptomatic hypophosphatemia are cause by
Deficiency atp
Hyperaldosteronism causes
Excuse excess and hypokalemia
Which disorder is caused by inhalation or organic substances
Hypersensitivity pneumonitis
A patient diagnosed with chronic compensated heart failure reports that, "My feet swelling o way salt but I don't understand why" the nurses best response is
I'm sat holds water in your blood and makes more pressure against your blood vessels, so fluid leaks out into your tissues and makes them swell
Chronic bronchitis often leads to cor pulmonale because of
Increased pulmonary vascular resistance
Major cause of treatment failure in tuberculosis is
Noncompliance
How is a patient hospitalized with a malignant tumor that secretes parathyroid hormone- related peptide monitored for the resulting electrolyte imbalance
Serum calcium, bowel function, level of consciousness
Which change in a patient's assessment has the greatest urgency
Serum potassium concentration is increasing; has developed cardias dysrhythmias, but denied any difficult breathing
Croup is characterized by
barking cough
A person who has hyperparathyroidism is likely to develop
hypercalcemia
The increased anterior-posterior chest diameter associated with obstructive lung disease is caused by
increased residual lung volumes
The finding of ketones in the blood suggests that a person may have
metabolic acidosis
Clinical manifestations of moderate to severe hypokalemia include
muscle weakness and cardiac dysrhythmias
fully compensated respiratory acidosis is demonstrated by
pH 7.36, PaCO2 55, HCO3- 36a
