A characteristic of monozygotic twins is that
- A. They are always of the same sex
- B. They share a similar fingerprint pattern
- C. They have different blood groups
- D. Superfetation is a common finding
Correct Answer: A
Rationale: The correct answer is A because monozygotic twins, also known as identical twins, develop from a single fertilized egg and share the same genetic material. This results in them always being of the same sex. Choice B is incorrect because fingerprint patterns are not solely determined by genetics. Choice C is incorrect because monozygotic twins will have the same blood group since they share the same DNA. Choice D is incorrect because superfetation, the fertilization of multiple eggs at different times during the same pregnancy, is not common in monozygotic twins.

Janet is a 54-year-old female who is in the ICU following hepatic resection due to metastatic disease. She is expected to move to a general medical floor today. Morning labs are as follows serum bilirubin approximately 2 gdL, albumin 3.1 gdL, and prothrombin time 20 seconds. AST and ALT are 85 and 99 respectively. The appropriate response would be to
- A. Cancel the transfer and keep her in the ICU
- B. Infuse albumin and fresh frozen plasma
- C. Repeat the labs the next day
- D. Prepare for reoperation
Correct Answer: B
Rationale: The correct answer is B: Infuse albumin and fresh frozen plasma. Given Janet's post-hepatic resection status and abnormal lab values indicating liver dysfunction (elevated bilirubin, low albumin, prolonged prothrombin time, elevated AST and ALT), she is at risk for coagulopathy and hypoalbuminemia. Infusing albumin can help improve her oncotic pressure and fluid balance, while fresh frozen plasma can replenish clotting factors to address the prolonged prothrombin time. This intervention aims to stabilize her condition before transferring to the general medical floor.
Canceling the transfer (Choice A) is not necessary if appropriate interventions can be taken. Repeating labs the next day (Choice C) delays potentially needed treatments. Preparing for reoperation (Choice D) is not indicated based on the information provided.
Causes of Down syndrome are
- A. Trisomy, deletion and non-disjunction
- B. Mosaicism, duplication and translocation
- C. Translocation, mosaicism and deletion
- D. Mosaicism, trisomy and translocation
Correct Answer: D
Rationale: The correct answer is D because Down syndrome is primarily caused by trisomy of chromosome 21. This means there is an extra copy of chromosome 21, leading to the characteristic features of the syndrome. Mosaicism and translocation of chromosome 21 can also result in Down syndrome, albeit less frequently. Option A includes deletion, which is not a common cause of Down syndrome. Option B lists duplication, which is not a typical mechanism for Down syndrome. Option C includes deletion and mosaicism, but trisomy is the main cause of Down syndrome, making option D the most accurate choice.
Pubiotomy is
- A. Access to the lower uterine segment by dissection of tissues around the peritoneum
- B. A surgical procedure in which the cartilage of the pubic symphysis is divided
- C. Ligating of the pubic bones in case they are invaded by cancerous cells
- D. Dissection of the perineal tissues to hasten the perineal phase of labor
Correct Answer: B
Rationale: The correct answer is B: A surgical procedure in which the cartilage of the pubic symphysis is divided. Pubiotomy involves cutting the pubic symphysis cartilage to widen the pelvic outlet during difficult childbirth. This procedure helps facilitate labor by increasing the pelvic diameter. Choices A, C, and D are incorrect because they do not accurately describe pubiotomy. Choice A refers to accessing the lower uterine segment, choice C involves ligating pubic bones for cancer, and choice D pertains to perineal tissue dissection during labor, which are unrelated to pubiotomy.
Fetal indications for cesarean section include
- A. Impacted face presentation, shoulder presentation, locked twins.
- B. Impacted face presentation, severe pre-eclampsia, locked twins.
- C. Cephalo-pelvic disproportion, shoulder presentation, locked twins.
- D. Cephalo-pelvic disproportion, impacted face presentation, locked twins.
Correct Answer: D
Rationale: The correct answer is D because fetal indications for cesarean section typically involve situations where the baby cannot safely be delivered vaginally. Cephalo-pelvic disproportion means the baby's head is too large to pass through the mother's pelvis, necessitating a C-section. Impacted face presentation can result in difficulty during delivery, also requiring a C-section. Locked twins refer to a situation where the babies are unable to move past each other during delivery, further indicating the need for a C-section. Choices A, B, and C include some relevant indications for a C-section, but they do not encompass the full range of fetal indications like choice D does.
The MAIN aim of encouraging plenty of fluids to a postnatal client with urinary tract trauma is to
- A. Control growth of organisms
- B. Keep client well hydrated
- C. Maintain proper fluid balance
- D. Facilitate proper healing
Correct Answer: B
Rationale: Step 1: Postnatal clients with urinary tract trauma are at risk of dehydration due to increased fluid loss.
Step 2: Encouraging plenty of fluids helps maintain hydration levels.
Step 3: Proper hydration supports kidney function and aids in flushing out bacteria, reducing infection risk.
Step 4: Adequate hydration also promotes tissue healing and prevents complications.
Step 5: Therefore, the main aim of encouraging plenty of fluids is to keep the client well hydrated.
