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
