What is the test for a prison officer to be found guilty of violating the Eighth Amendment by failing to provide adequate care and facilities for a prisoner in solitary confinement?

Gamble, 429 U.S. 97, 102 (1976). Conditions of confinement may, however, be harsh and restrictive. See Rhodes v. Chapman, 452 U.S. 337, 347 (1981). Nonetheless, prison officials must provide prisoners with "food, clothing, shelter, sanitation, medical care, and personal safety." Toussaint v. McCarthy, 801 F.2d 1080, 1107 (9th Cir. 1986). A prison official violates the Eighth Amendment only when two requirements are met: (1) objectively, the official's act or omission must be so serious such that it results in the denial of the minimal civilized measure of life's necessities; and (2) subjectively, the prison official must have acted unnecessarily and wantonly for the purpose of inflicting harm. See Farmer, 511 U.S. at 834. Thus, to violate the Eighth Amendment, a prison official must have a "sufficiently culpable mind." See id.
