Ms. Jackson has been suffering from persistent vomiting for two days. She appears to be lethargic and weak and has myalgia. She is noted to have dry mucous membranes and her capillary refill time takes more than 4 seconds. She is diagnosed with gastroenteritis and dehydration. Measurement of arterial blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34 mmol/L. What acid base disorder is shown?
Metabolic Alkalosis, Partially Compensated
Respiratory Acidosis, Partially Compensated
Respiratory Alkalosis, Uncompensated
Metabolic Alkalosis, Uncompensated
The Correct Answer is D
Choice A reason: This choice is incorrect. Partial compensation would typically involve a change in PaCO2 to counterbalance the elevated bicarbonate, which is not observed here.
Choice B reason: This choice is incorrect. Respiratory acidosis is characterized by a low pH and an elevated PaCO2, which is not consistent with the given values.
Choice C reason: This choice is incorrect. Respiratory alkalosis would present with a low PaCO2 due to hyperventilation, which is not the case here.
Choice D reason: This is the correct choice. The elevated pH and HCO3 with a normal PaCO2 indicate metabolic alkalosis without respiratory compensation. Persistent vomiting can lead to loss of stomach acid, which causes metabolic alkalosis.

Correct Answer is D
Explanation
Choice A reason: This choice is incorrect. A stroke involving the right cerebral hemisphere typically affects the left side of the body and can cause problems with spatial and perceptual abilities, not necessarily with language or discrimination of words and letters, which are more commonly associated with left hemisphere strokes⁸.
Choice B reason: Motor retardation is not specific to right hemisphere strokes. While right hemisphere strokes can cause weakness on the left side of the body, the term 'motor retardation' is not commonly used to describe this symptom⁸.
Choice C reason: This choice is incorrect because deficits in the right visual field would suggest a problem with the left cerebral hemisphere, not the right. A right hemisphere stroke typically causes problems with the left visual field⁸.
Choice D reason: This is the correct choice. Individuals with right hemisphere strokes may exhibit poor impulse control, as the right hemisphere is involved in judgment and behavior regulation⁸.
Correct Answer is C
Explanation
Choice A reason: This choice is incorrect as painless, raised purple nodules on the hard palate are not typically indicative of squamous cell carcinoma.
Choice B reason: This choice is incorrect because a small macule with a yellow-brown scale does not describe squamous cell carcinoma, which often presents as a firm nodule with a scaly crust.
Choice C reason: This choice is correct. Squamous cell carcinoma can present as a firm nodule with a hard, scaly crust on the skin.
Choice D reason: Yellow white patches of growth on the tongue are more indicative of conditions such as oral leukoplakia, not squamous cell carcinoma.
