Lab 2 Study Guide - Bovine Pregnancy Diagnosis

Which of the following best describes the progression of uterine artery changes detectable via rectal palpation as gestation advances in bovine?

A veterinarian palpates a cow and detects a 9 cm amniotic vesicle and membrane slip. Based on the provided data, what is the most likely gestational age?

Differentiating between a pyometra and early pregnancy (around 30-40 days) in bovine via rectal palpation can be challenging. Which palpation finding would be MOST indicative of pregnancy rather than pyometra at this stage?

Considering the risk of embryonic loss due to rectal palpation, at what gestational age is the risk of pregnancy disruption generally considered to be MOST critical and require extreme caution?

You palpate a placentome that is approximately the size of a 'dime'. According to the table, what is the approximate gestational age?

Which of the following represents the MOST accurate gestational age range for diagnosing twin pregnancies via transrectal palpation based on the provided information?

If you identify a fetal nose to crown length of approximately 10.5 cm during rectal palpation, what fetal size description from the table corresponds to this measurement?

Considering the progression of fetal size during gestation as indicated in the table, which of the following sequences accurately reflects the increasing size?

In bovine pregnancy diagnosis, what is the PRIMARY limitation of relying solely on 'membrane slip' as a definitive sign, particularly in later gestation (beyond 90 days)?

For accurate fetal age assessment using transrectal palpation, which parameter from the table provides the MOST reliable estimation across a wider range of gestation (e.g., 60-150 days)?

A veterinary student is learning rectal palpation for pregnancy diagnosis. Based on the table, at which gestational age is it generally considered clinically relevant to be able to confidently detect a 'string' in the uterine horn?

Considering the 'Clinical experience required' feature in the table, which method of pregnancy detection likely demands the HIGHEST level of expertise for accurate interpretation and execution?

If a cow is presented for pregnancy diagnosis and upon rectal palpation, the uterine horn diameter is estimated to be 7 cm, and fremitus is just becoming palpable in the ipsilateral uterine artery, what is the MOST likely gestational age range?

Comparing transrectal palpation and ultrasound for pregnancy diagnosis, which of the following statements accurately reflects a key ADVANTAGE of ultrasound in early pregnancy detection (e.g., < 60 days)?

Which of the following is LEAST likely to be considered a 'cardinal' or definitive sign of pregnancy upon rectal palpation in bovine, especially in early to mid-gestation?

If a cow is diagnosed pregnant at 35 days via rectal palpation based on amniotic vesicle and membrane slip, and then re-palpated at 65 days, what would be the expected change in amniotic vesicle size based on the provided table?

Considering the 'Cost' feature of pregnancy diagnosis methods, which of the following represents the typical order from LEAST to MOST expensive per diagnosis in bovine practice?

A farmer reports that a cow was artificially inseminated 130 days ago. Upon rectal palpation, you detect fremitus on the side of the pregnant horn, and estimate the uterine horn diameter to be approximately 15 cm. Are these findings consistent with the reported breeding date, and why?

In the context of pregnancy diagnosis, the term 'fremitus' in the uterine artery during rectal palpation is BEST described as:

For which of the following purposes is ultrasound generally considered to offer the MOST significant ADVANTAGE over transrectal palpation in bovine pregnancy diagnosis?
