When a patient makes eight errors within 1.5 minutes while performing serial 7s, the nurse concludes that the patient has which of the following?
a. normal calculation ability c. dyscalculia
b. confabulation d. constructional apraxia
C
A patient should be able to calculate the correct numbers upon subtraction or addition within educational abilities and with fewer than four errors in less than 1 1/2 minutes. Because the patient makes eight errors in 1.5 minutes while performing serial 7s, the nurse would conclude that the patient has dyscalculia, the inability to perform calculations. Dyscalculia can be caused by depression or anxiety, dementia, or mental retardation. The most common cause of dyscalculia is focal lesions in the dominant parietal lobe; however, calculation deficits have also been ascribed to focal lesions in the frontal, temporal, and occipital lobes. Confabulation involves making up answers unrelated to facts, and is also abnormal. Constructional apraxia is the inability to reproduce drawn figures on paper.
