How can a healthcare provider support a woman with hyperemesis gravidarum?

Correct Answer: A

Rationale: The correct answer is A: Prescribe anti-nausea medication. This is the most appropriate choice to manage hyperemesis gravidarum, a severe form of morning sickness. Anti-nausea medication can help alleviate symptoms and prevent dehydration. Choice B (Recommend bed rest) may not directly address the nausea and vomiting associated with hyperemesis gravidarum. Choice C (Suggest a high-protein diet) and D (Advise on exercise) may not be effective in managing the condition or providing immediate relief from symptoms. Anti-nausea medication is the most evidence-based approach to support a woman with hyperemesis gravidarum.

Correct Answer: C

Rationale: The correct answer is C: A long history of alcohol use. In this case, the patient T. S. is brain dead following a catastrophic accident. Although she had an organ donor notation, her long history of alcohol use precludes her from serving as a liver donor. Chronic alcohol use can lead to liver damage and compromise the quality of the liver for transplantation. Encephalopathy (choice A) is a potential complication of liver disease, but it does not preclude her from being a liver donor. Hepatitis C infection (choice B) and biliary cirrhosis (choice D) may affect the liver, but they do not automatically disqualify her as a donor.

Correct Answer: D

Rationale: The correct answer is D because placenta praevia can lead to severe bleeding during childbirth, posing high risks to both the mother and the baby. This condition occurs when the placenta partially or completely covers the cervix, leading to bleeding as the cervix dilates during labor. Choice A is incorrect because bleeding in placenta praevia is not related to the segment preparing for labor. Choice B is incorrect as bleeding is primarily due to the abnormal placement of the placenta, not from pathological processes. Choice C is incorrect as bleeding can occur before 37 weeks in cases of placenta praevia.

Correct Answer: C

Rationale: The correct answer is C: Magnesium sulphate. It is the drug of choice in managing eclampsia due to its ability to prevent and control seizures. Magnesium sulfate is a central nervous system depressant that reduces neuronal excitability and neuromuscular transmission, thus preventing seizures. It also helps in lowering blood pressure and preventing complications. Phenobarbitone (A) is not the first-line treatment for eclampsia. Calcium gluconate (B) is used for calcium deficiency, not eclampsia. Sodium bicarbonate (D) is used to correct acidosis, not for managing eclampsia.

Correct Answer: C

Rationale: The correct answer is C because radiation and substances of abuse are known teratogenic causes of congenital abnormalities. Radiation exposure can lead to genetic mutations and developmental issues in the fetus. Substances of abuse like alcohol, tobacco, and illicit drugs can also negatively impact fetal development. A: Medical conditions and pesticides may have negative effects on pregnancy outcomes, but they are not typically classified as teratogenic causes of congenital abnormalities. B: Prescription drugs can be teratogenic in some cases, but not all prescription drugs have harmful effects on fetal development. Chromosomes are not typically considered teratogenic causes. D: Disordered genes can lead to congenital abnormalities, but they are not classified as teratogenic causes. Medical conditions are not universally teratogenic.
