Irritation of the diaphragm by an inflamed gallbladder can cause referred pain to the right shoulder via which nerve?
Phrenic nerve
Vagus nerve
Intercostal nerve

Diaphragmatic irritation sends pain fibers via the phrenic nerve (C3–C5) to the shoulder area, explaining referred pain in diaphragmatic or subdiaphragmatic pathology. Wikipedia: Phrenic nerve
What is the first-line imaging modality for evaluating gallstones in the right upper quadrant?
CT scan
MRI
Ultrasound
Abdominal X-ray
Ultrasound is the preferred initial test for gallstones due to its high sensitivity, low cost, and lack of radiation. CT and MRI are reserved for complications or unclear cases. Wikipedia: Gallstones diagnosis

The larger right lobe receives more blood flow and is more susceptible to abscess formation from systemic infections or biliary tract disease. NCBI Bookshelf: Liver abscess
Which peritoneal fold attaches the liver to the anterior abdominal wall in the right upper quadrant?
Falciform ligament
Hepatoduodenal ligament
Hepatogastric ligament
Coronary ligament
The falciform ligament is a sickle-shaped fold of peritoneum that connects the liver to the anterior abdominal wall and diaphragm. The hepatoduodenal and hepatogastric ligaments are parts of the lesser omentum. Wikipedia: Falciform ligament

According to Couinaud’s segmentation, which liver segments constitute the right posterior section located in the right upper quadrant?
Segments VI and VII

Cheat Sheet

  1. Liver's Right Lobe -

    The RUQ contains which structure that bears most of the metabolic burden? The liver's right lobe occupies the majority of the RUQ and is responsible for detoxification, protein synthesis, and bile production (Gray's Anatomy, 42nd ed.). Remember "Real" in "Real Good Drinks Please, Kid" to recall the right lobe.

  2. Gallbladder Positioning -

    The gallbladder nests beneath the visceral surface of the right lobe of the liver, storing and concentrating bile until digestion of fats. In an RUQ anatomy quiz, pinpointing its location near the inferior liver border is crucial for understanding cholecystitis and bile flow disorders (Mayo Clinic).

  3. Duodenum and Pancreatic Head -

    The first segment of the small intestine, the duodenum, along with the head of the pancreas, also resides in the RUQ. These structures collaborate in enzymatic digestion and are tested frequently in human body structure quizzes to assess knowledge of digestive physiology (Netter's Atlas of Human Anatomy).

  4. Right Kidney and Adrenal Gland -

    The upper pole of the right kidney and its adrenal gland partially extend into the RUQ behind the peritoneum. Reviewing their retroperitoneal positioning helps when tackling body function trivia questions about filtration and hormone release.

  5. Surface Landmark Mnemonics -

    Use the vertical midclavicular line and horizontal transumbilical plane to map the four abdominal quadrant structure. A quick mnemonic: "Real Good Drinks Please, Kid" (Right liver, Gallbladder, Duodenum, Pancreatic head, Kidney) simplifies recall during an RUQ anatomy quiz.
