Michael has been diagnosed with frontal lobe abnormalities. As part of his care and evaluation, it is important to understand the specific functions that the frontal lobe is responsible for.
Which of the following functions are primarily controlled by the frontal lobe?
Decision-making, problem-solving, and planning
Vision and color recognition
Language comprehension and memory
Movement coordination and balance
The Correct Answer is A
A. Decision-making, problem-solving, and planning: The frontal lobe is primarily responsible for higher-order executive functions such as reasoning, decision-making, problem-solving, judgment, and planning. It also plays a role in personality and voluntary motor control, especially through the prefrontal cortex and motor areas.
B. Vision and color recognition: These functions are associated with the occipital lobe, which is located at the back of the brain and specializes in processing visual input, including aspects like color, shape, and motion.
C. Language comprehension and memory: Language comprehension is primarily controlled by Wernicke’s area, which is located in the temporal lobe. Memory is also associated with the temporal lobe and the limbic system structures like the hippocampus.
D. Movement coordination and balance: These are functions of the cerebellum, which regulates fine motor control, coordination, balance, and posture—not the frontal lobe.

Correct Answer is B
Explanation
A. Proteus mirabilis: While Proteus mirabilis is a recognized cause of UTIs, especially in catheterized patients or those with structural abnormalities, it is not the most common pathogen overall.
B. Escherichia coli: E. coli is by far the most common pathogen responsible for urinary tract infections, accounting for approximately 80–90% of uncomplicated UTIs due to its ability to adhere to the uroepithelium with fimbriae.
C. Staphylococcus saprophyticus: This organism is a common cause of UTIs in sexually active young women, but overall it is much less prevalent than E. coli across all age groups and sexes.
D. Klebsiella pneumoniae: Although K. pneumoniae can cause UTIs, particularly in hospitalized or immunocompromised patients, it is not as frequently encountered as E. coli in community-acquired cases.
Correct Answer is D
Explanation
A. This option incorrectly matches the terms: cholelithiasis refers to gallstones, not stones in the common bile duct; cholecystitis is inflammation of the gallbladder, not the common bile duct; choledocholithiasis refers to stones in the common bile duct, not inflammation.
B. This option reverses definitions: cholangitis is inflammation of the common bile duct, not gallstones; cholecystitis is inflammation of the gallbladder, not stones in the common bile duct; choledocholithiasis refers to stones in the common bile duct, not inflammation.
C. This option mislabels choledocholithiasis as inflammation of the common bile duct, but it actually refers to stones in the common bile duct; cholecystitis is inflammation of the gallbladder, not stones in the common bile duct; cholangitis is inflammation of the common bile duct, not the gallbladder.
D. This option correctly matches the terms: cholelithiasis means gallstones; choledocholithiasis refers to stones in the common bile duct; cholangitis is inflammation of the common bile duct; cholecystitis is inflammation of the gallbladder.
