Correct Answer: B

Rationale: The correct answer is B: His procedure has put him at significant risk for B12 absorption problems. Rationale: 1. Jejunum is primarily responsible for nutrient absorption, including B12. 2. Resection of a large portion of the jejunum can lead to malabsorption of B12. 3. B12 is essential for neurological function and red blood cell production. 4. Patients with significant jejunum resection are at high risk for B12 deficiency. 5. Monitoring B12 levels and potentially requiring supplementation is crucial for patients like Jake. Summary of other choices: A: Incorrect. Lifetime issues with diarrhea are not necessarily expected following jejunum resection. C: Incorrect. The ileum may assume some functions of the jejunum but cannot fully compensate. D: Incorrect. Enteral nutrition should not be delayed for months as it is essential for Jake's recovery and nutritional needs.

Correct Answer: C

Rationale: The correct answer is C: Secondary postpartum haemorrhage. This term refers to excessive bleeding from the genital tract after the first 24 hours but within the puerperium period (6 weeks postpartum). A: Primary postpartum haemorrhage occurs within the first 24 hours after delivery. B: Tertiary postpartum haemorrhage occurs more than 6 weeks postpartum. D: Incidental postpartum haemorrhage is not a recognized medical term for postpartum bleeding.

Correct Answer: A

Rationale: The correct answer is A: TRUE. Uterine atony is the most common cause of immediate postpartum hemorrhage due to inadequate uterine contraction to control bleeding. This is supported by research and clinical evidence. Trauma to the genital tract is a less common cause and usually leads to delayed hemorrhage. Choice B is incorrect as uterine atony is a well-documented primary cause. Choice C is incorrect as uterine atony is consistently the leading cause. Choice D is incorrect as the cause of immediate postpartum hemorrhage is clear, with uterine atony being the most common culprit.

Correct Answer: D

Rationale: The correct answer is D: Compound presentation. This term refers to the situation where there is more than one part of the fetus on the pelvic brim at the onset of labor. This can include a hand or arm alongside the head or another body part. The other choices are incorrect because: A: Unstable lie refers to the fetus being in a transverse position. B: Fetal malpresentation indicates an abnormal presentation of the fetus, such as breech or transverse. C: Fetal malposition refers to the fetus being in a suboptimal position, like occiput posterior. Thus, the best choice is D as it specifically describes the scenario of multiple fetal parts on the pelvic brim.

Correct Answer: B

Rationale: The correct answer is B: Facilitation of weight gain. A thermal controlled environment for a low birth weight baby helps in maintaining the baby's body temperature, reducing energy expenditure, and promoting weight gain. This is crucial for the baby's growth and development. Incorrect choices: A: Prevention of infection - While a thermal controlled environment can indirectly help prevent infections by maintaining the baby's health, it is not the primary aim. C: Provision of quality care - Quality care involves multiple aspects beyond just thermal control, so this is not the primary aim. D: Provision of nutrition - Nutrition is important for weight gain, but the thermal controlled environment specifically focuses on regulating the baby's body temperature to support weight gain.
