Morphine is given in acute pulmonary edema to redistribute the pulmonary circulation to the periphery by decreasing:

Correct Answer: B

Rationale: Morphine is given in acute pulmonary edema to decrease pulmonary capillary pressure. By reducing pulmonary capillary pressure, morphine helps to redistribute the pulmonary circulation to the periphery, leading to improved oxygenation and decreased symptoms of pulmonary edema. Morphine works to vasodilate the blood vessels, which ultimately helps decrease the pressure in the pulmonary capillaries, allowing for improved blood flow to the periphery of the lungs. This redistribution of pulmonary circulation helps to alleviate the congestion and fluid buildup in the lungs that occurs in acute pulmonary edema.

Correct Answer: D

Rationale: Kasabach-Merritt syndrome is not typically associated with hemangiomas.

Correct Answer: D

Rationale: When ARF deteriorates and electrolyte imbalances worsen, peritoneal dialysis (via a Tenckhoff catheter) is indicated.

Correct Answer: A

Rationale: Older age is generally considered a poor prognostic factor, but not necessarily worse than other listed options.

Correct Answer: A

Rationale: The statement "Diabetes mellitus is three times more common in Hispanics than in Blacks or Whites" is accurate and supported by data. Studies have shown that diabetes mellitus, particularly type 2 diabetes, is more prevalent among Hispanic populations compared to Black or White populations. Factors such as genetic predisposition, lifestyle choices, and socioeconomic status can contribute to this disparity. It is important for healthcare providers to be aware of these trends to provide appropriate and culturally sensitive care to individuals at higher risk for diabetes.
