Midwifery Exam Questions and Answers PDF

Correct Answer: D

Rationale: Step 1: The presence of bile in vomitus suggests that the vomit originated from the small intestine or stomach, indicating an obstruction in the pyloric region. Step 2: Pyloric stenosis is a condition characterized by narrowing of the opening from the stomach to the small intestine, leading to projectile vomiting with bile. Step 3: Therefore, the presence of bile in vomitus suggests pyloric stenosis, making option D the correct answer. Summary: Option A is incorrect because vomiting preceding pain does not necessarily indicate a surgical abdomen. Option B is incorrect as the severity of symptoms is not solely based on age. Option C is incorrect as some surgical abdomens can present with vomiting as a primary symptom.

Correct Answer: A

Rationale: The correct answer is A because occipito-posterior position can lead to prolonged labor due to poor fetal positioning, causing maternal back pain. This can result in fetal distress as the baby may have difficulty descending through the birth canal. Postpartum hemorrhage, uterine rupture, fetal death (choices B and C) are not typically associated with occipito-posterior position. Therefore, choice A is the most appropriate answer.

Correct Answer: A

Rationale: The correct answer is A because an estimated fetal weight below 3500 grams indicates a lower risk of complications during childbirth. Higher fetal weight increases the likelihood of shoulder dystocia and birth injuries. Maternal body mass index, gestational age, and maternal age do not directly impact the likelihood of a favorable outcome during a trial of scar.

Correct Answer: D

Rationale: The correct answer is D: Escherichia coli. E. coli is the most common causative organism of pyelonephritis due to its prevalence in the gastrointestinal tract. It has specific virulence factors that enable it to ascend the urinary tract and cause infection. Streptococcus faecalis, Proteus vulgaris, and Staphylococcus pyogene are less commonly associated with pyelonephritis compared to E. coli.

Correct Answer: B

Rationale: The correct answer is B because the absence of any other abnormal findings suggests that Mr. Thornton is currently experiencing an anterior wall infarction. This is indicated by the localized area of myocardial necrosis due to prolonged ischemia. Option A is incorrect because ischemia would typically present with reversible changes rather than necrosis. Option C is incorrect as NSTEMI would show some abnormal findings. Option D is incorrect as STEMI would show more significant ECG changes and enzyme elevation. In summary, the absence of other abnormalities points towards an acute event like an anterior wall infarction.
