The client's last menstrual period (LMP) was December 17th, 2016 According to Nägele's Rule her expected cate of delivery (EDD) is:

A. Sausage-shaped mass in the upper midabdomen: A sausage-shaped mass is more characteristic of intussusception rather than hypertrophic pyloric stenosis. Intussusception typically presents with intermittent abdominal pain, currant jelly stools, and a palpable tubular mass. Projectile vomiting without bile is not the classic presentation for this finding.

B. Hard, moveable, olive-shaped mass in the right upper quadrant: Hypertrophic pyloric stenosis classically presents with a firm, olive-shaped mass in the right upper quadrant or epigastric area. This mass represents the hypertrophied pyloric muscle and is most often palpated during feeding. Progressive, forceful projectile vomiting is a hallmark feature supporting this finding.

C. Tenderness over the McBurney point in the right lower quadrant: McBurney point tenderness is associated with acute appendicitis, which is rare in infants this young. Appendicitis presents with localized right lower quadrant pain, fever, and guarding rather than projectile vomiting.

D. Abdominal pain in the epigastric or umbilical region: Diffuse or localized abdominal pain is more typical of conditions such as gastroenteritis or early appendicitis. Infants with pyloric stenosis usually appear hungry after vomiting and do not typically demonstrate abdominal pain. The key finding is a palpable mass rather than pain.

A. Heart: Heart assessment, including auscultation of rate and rhythm, can be performed while the newborn is calm or sleeping. It does not typically disturb the infant and provides important baseline cardiovascular data early in the examination.

B. Abdomen: Abdominal inspection and palpation can be performed while the newborn is lying quietly. Gentle handling usually does not awaken the infant, and assessing for organ size, tenderness, or masses is best done before more invasive or stimulating procedures.

C. Lungs: Lung auscultation can be done with minimal disturbance to the sleeping newborn, allowing assessment of respiratory rate, breath sounds, and effort without causing agitation. This is often performed after heart and abdominal assessments.

D. Throat: Examination of the throat is invasive and often triggers gagging or crying. Performing it last minimizes disruption to the newborn, ensuring that earlier assessments can be completed while the infant remains calm and asleep.
