Correct Answer: C

Rationale: The correct answer is C: Gram negative infection. In sepsis, especially with a Gram negative infection, organ donation may pose a risk of transmitting the infection to the recipient. This can be life-threatening for the organ recipient. Renal failure (choice A), traumatic brain injury (choice B), and breast cancer (choice D) are not direct contraindications to organ donation. Renal failure may limit the suitability of certain organs, but it does not automatically disqualify a patient from donating other organs. Traumatic brain injury may impact brain donation but does not rule out other organ donation. Breast cancer may affect eligibility for certain organs but does not universally disqualify a patient from organ donation.

Correct Answer: A

Rationale: The correct answer is A: Inspiration. Laryngeal stridor is caused by narrowed or obstructed airway, resulting in noisy breathing. During inspiration, the air is drawn through the narrowed larynx, causing the stridor sound. During expiration, the air is leaving the body, so the noise may not be as prominent. Choices C and D, feeding and play, are unrelated to the respiratory process and do not affect the presence of laryngeal stridor.

Correct Answer: B

Rationale: In uterine inversion, the fundus is the last part to be replaced due to its position being the deepest inside the vagina. The fundus is the upper portion of the uterus and is the last part to invert back into its normal position. The cervix, isthmus, and body are parts of the uterus that are more easily replaced during the process of uterine inversion. The fundus being the final part to be replaced ensures the uterus is fully restored to its correct orientation.

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: Protein intake of 50 g daily. In hepatic encephalopathy, reducing protein intake helps decrease ammonia production. Excessive ammonia leads to neurological symptoms. Lactulose (choice A) is correct for hepatic encephalopathy as it helps eliminate ammonia through the gut. Spironolactone (choice B) is a diuretic and not indicated for hepatic encephalopathy. Zolpidem (choice D) is a sleep aid and not relevant to managing ammonia accumulation. In summary, choice C is correct because it directly targets the underlying issue of ammonia accumulation in hepatic encephalopathy, while the other choices do not address this specific concern.
