Classify the following arterial blood gas: pH = 7.52, PaCO2 = 30 mm Hg, HCO3- = 24 mEq/L.
Administration of sodium bicarbonate to an individual with acidosis will
increase formation of carbon dioxide in the blood.
Renal artery stenosis, hypertension, and nephrosclerosis may all contribute to renal failure by causing
A person who experiences a panic attack and develops hyperventilation symptoms may experience.
numbness and tingling in extremities.
A patient's serum level upon admission was 148 mEq/L, her heart rate was 110 lying supine, and her blood pressure was 88/60. What is the most appropriate fluid therapy
Give IV normal saline (0.9%).
The most helpful laboratory value in monitoring the progression of renal failure is
The finding of ketones in the urine suggests that a patient may have which of the following acid-base disorders
Abnormalities in intracellular regulation of enzyme activity and cellular production of ATP are associated with
A total of 70% to 80% of the water and electrolytes filtered by the kidney are reabsorbed by the
Vomiting of stomach contents or continuous nasogastric suctioning may predispose to development of
metabolic acid deficit.
Which of the following hormones is associated with an increase in hypotonic fluid reabsorption from the tubular fluid
A high urine sodium and a fractional sodium excretion greater than 1 is associated with:
acute tubular necrosis.
Decreased neuromuscular excitability can be seen in which two electrolyte disorders
Hypercalcemia and hypermagnesemia
Because of continuing decreased urine output, the function of a patient's kidneys is evaluated with urine electrolytes. The urine Na+ is found to be quite low. This is most likely due to
aldosterone effect on kidney tubules.
C.G. is a 42-year-old with type 1 diabetes that is normally well controlled with insulin. Three days ago she developed a viral infection with high fever and has not been checking her blood glucose regularly. She is now in the emergency department complaining of abdominal pain and flu symptoms. C.G.'s urine is positive for glucose and ketones, and serum glucose and blood gases are obtained. What fluid balance problem is C.G. at risk for secondary to glycosuria?
A patient with gouty arthritis develops renal calculi. The composition of these calculi is most likely to be
uric acid crystals.
Osmoreceptors located in the hypothalamus control the release of
vasopressin (antidiuretic hormone, ADH).
A 14-month-old girl is brought to urgent care by her parents for persistent fever, vomiting, and diarrhea. Upon questioning, the parents report that the child has had only one to two wet diapers per day for the last 2 days. The child's weight is noted to be 2 pounds less than her normal weight. This is equivalent to approximately how much fluid loss?
