Correct Answer: C

Rationale: The correct answer is C (900 mL) because the weight of 900 g corresponds to a blood loss of the same amount in milliliters. Blood density is close to that of water, so 1 g ? 1 mL. Therefore, a blood-soaked peripad weighing 900 g indicates a blood loss of 900 mL. Choice A (1800 mL) is incorrect as it doubles the weight instead of converting it to milliliters. Choice B (450 mL) is incorrect as it halves the weight. Choice D (90 mL) is incorrect as it divides the weight by 10, which is too small for the blood loss indicated.

Correct Answer: C

Rationale: Rationale for Correct Answer (C - Taper infusion gradually): 1. Tapering the infusion gradually allows for a smooth transition off PN without causing metabolic disturbances. 2. Abruptly stopping PN can lead to hypoglycemia and electrolyte imbalances. 3. Increasing the rate may cause fluid overload or hyperglycemia. 4. Hanging 5% dextrose alone does not provide adequate nutrition and may not meet the patient's needs.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests (LFTs). Yellow skin can indicate jaundice, a sign of liver dysfunction, often seen in patients with liver issues or chemotherapy-related liver toxicity. LFTs including bilirubin, ALT, AST, and ALP can help assess liver function. B: Complete blood count (CBC) and C: Platelet count are not directly related to yellow skin and would not provide information on liver function. D: Blood urea nitrogen and creatinine are tests for kidney function, not liver function. While kidney dysfunction can sometimes cause yellow skin, LFTs are more specific for assessing liver function in this context.

Correct Answer: A

Rationale: The correct answer is A because administering a lethal dose of medication to a patient whose death is imminent directly causes the patient's death, constituting assisted suicide. This action is intentional and aims to end the patient's life. In contrast, choices B, C, and D do not involve intentionally causing the patient's death. Choice B involves a medication error but not with the intent to end the patient's life. Choice C respects the patient's autonomy in refusing treatment. Choice D honors the patient's wishes for end-of-life care. Thus, only choice A aligns with the definition of assisted suicide.

Correct Answer: D

Rationale: The correct answer is D: Bacteria. In a patient with a urinary tract infection (UTI), bacteria are typically present in the urine due to the infection of the urinary system. Bacteria may be detected through urine culture or microscopic examination. A: Casts are not typically associated with UTIs but can indicate kidney disease. B: Protein in the urine can indicate kidney damage or other issues, not specific to UTIs. C: Crystals in the urine can be normal or indicate specific conditions, but they are not specific to UTIs. In summary, the presence of bacteria in the urine is a key indicator of a UTI, while the other choices are more indicative of different conditions or factors.
