The provision of medical care to prisoners in a county jail is a nondelegable duty such that an independent contractor hired to perform that duty is an agent of the Sheriff for purposes of N.C. Gen. Stat. § 14-27.7(a).
From May of 2003 through January of 2004, David Edward Wilson (“defendant”) was employed by Prison Health Services as a mental health clinician. His duties required him to work with inmates in the Mecklenburg County Jail. Nina Greene was an inmate at the jail during that time awaiting trial on drug charges. She sought mental health treatment for sleeping disorders which arose after she learned of health issues involving her mother and brother-in-law. On or about 30 December 2003, defendant met with Greene in the jail’s “sick call room.” This room was small with no windows, had only two chairs, and a sink. After talking with defendant, Greene felt uncomfortable during a period of silence in the conversation. She stood up to leave, and extended her hand to defendant. Defendant replied that a handshake was too formal, and Greene gave defendant a hug. During the hug, defendant brushed one of Greene’s breasts. The next day, Greene met with defendant again, and he brought her some material on grieving. He asked Greene if she had any money in her commissary account. Greene responded that she did not need anything. Defendant gave Greene his number and told her to call him when she was released. She said that she did not “do anything without getting paid for it.”
The next meeting between Greene and defendant was during the first week of January 2004. During that visit, Greene raised her shirt *102and allowed defendant to fondle her breasts in exchange for defendant placing money in her commissary account. On 6 January 2004, defendant again met Greene in the sick call room and presented her with a blank money order in the amount of $50.00. Greene told defendant that she could not have sexual intercourse with him because she was having her period. Greene performed an act of fellatio on defendant in exchange for the money order. Before departing the sick call room, defendant and Greene agreed to meet on 9 January 2004, in order to engage in sexual intercourse. Upon returning to her cell, Greene’s cell mate noticed Greene was acting differently and asked what was wrong. Greene confided to her cell mate what had occurred with defendant. The cell mate then told the captain at the jail what had occurred between Greene and defendant. The captain spoke with Greene and she told her what had occurred and what was planned for 9 January 2004. Greene attempted to advise defendant through a note that the captain was going to place a video camera in the sick call room on 9 January 2004, but the note was intercepted by the jail staff and never reached defendant. On 9 January 2004, defendant and Greene met in the sick call room. Defendant dropped his pants and began to put a condom on his penis. The captain then entered the room and interrupted the encounter between defendant and Greene.
Defendant was charged with sexual activity by a custodian, attempted sexual activity by a custodian, and crime against nature. He was tried during the 31 October 2005, Criminal Session of Superior Court of Mecklenburg County. On 1 November 2005, the jury returned verdicts of guilty on all counts. The trial court consolidated the convictions for sentencing and imposed a sentence of 25 to 39 months imprisonment. This sentence was suspended and defendant was placed on supervised probation. Defendant appeals.
We note initially that the issues raised in defendant’s appeal only pertain to the convictions for sexual activity by a custodian and attempted sexual activity by a custodian, and do not pertain to the conviction for crime against nature.
[1] In his first argument, defendant contends that the trial court erroneously granted the State’s motion in limine, barring the introduction of a contract between Prison Health Services and the Mecklenburg County Sheriff. Defendant argues that the contract would have provided evidence that he was an independent contractor; not an agent or employee of the Mecklenburg County Sheriff. We disagree.
*103When reviewing a trial court’s ruling on a motion in limine, this Court’s standard of review is abuse of discretion. State v. Ruof, 296 N.C. 623, 628, 252 S.E.2d 720, 724 (1979). We note that defendant requested voir dires and made proffers of the evidence he sought to have admitted into evidence. This was sufficient to preserve the trial court’s ruling on the motion in limine for appellate review. See State v. Tutt, 171 N.C. App. 518, 520, 615 S.E.2d 688, 690 (2005).
The statute under which defendant was convicted provides that:
[I]f a person . . . who is an agent or employee of any person, or institution, whether such institution is private, charitable, or governmental, having custody of a victim of any age engages in vaginal intercourse or a sexual act with such victim, the defendant is guilty of a Class E felony. Consent is not a defense to a charge under this section.
N.C. Gen. Stat. § 14-27.7(a) (2005). The contract the trial court barred as evidence included a provision stating that Prison Health Services was an independent contractor. Defendant sought to introduce the contract because as an employee of Prison Health Services, he contends that he was an independent contractor and not an agent or employee of the Mecklenburg County Sheriff, and thus cannot be charged or convicted under N.C. Gen. Stat. § 14-27.7(a). Defendant’s argument is misplaced.
The State based its motion in limine before the trial court on the Supreme Court case of Medley v. N.C. Dep’t of Correction, 330 N.C. 837, 412 S.E.2d 654 (1992). In Medley, the Supreme Court held that providing medical care to those incarcerated in the State Department of Correction was a nondelegable duty of the State, and thus any independent contractor hired to perform that duty was an agent of the State as a matter of law. Id. 330 N.C. at 841, 412 S.E.2d at 657. The facts in Medley are not identical to those in the instant case. The statute which was the basis of the Supreme Court’s holding in Medley, N.C. Gen. Stat. § 148-19, specifically applied to the State Department of Correction. However, we are persuaded that the rationale of Medley is equally applicable to county jails and the facts of the instant case.
A nondelegable duty may arise from circumstances recognized at common law and statute, and in “situations wherein the Law views a person’s duty as so important and so peremptory that it will be treated as nondelegable. Defendants who are under such *104a duty ‘. .. cannot, by employing a contractor, get rid of their own duty to other people, whatever the duty may be.’ ” 5 Fowler V. Harper et.al., The Law of Torts § 26.11, at 83 (2d ed. 1986) (quoting Hardaker v. Idle Dist. Council, 1 Q.B. 335, 340 (C.A.) (1896)).
The State of North Carolina has long recognized the duty of providing medical care to prisoners. See, e.g., Medley, 330 N.C. at 842, 412 S.E.2d at 657; State v. Sparks, 297 N.C. 314, 321, 255 S.E.2d 373, 378 (1979) (stating that the State has a duty to provide medical care to prisoners); Spicer v. Williamson, 191 N.C. 487, 490, 132 S.E. 291, 293 (1926) (holding that the public is required to care for a prisoner when his liberty has been deprived). This duty has been codified in our General Statutes. See N.C. Gen. Stat. §§ 148-19 (2005). In Medley, the Supreme Court held that:
the duty to provide adequate medical care to inmates, imposed by the state and federal Constitutions, and recognized in state statute and case law, is such a fundamental and paramount obligation of the state that the state cannot absolve itself of responsibility by delegating it to another.
Medley, 330 N.C. at 844, 412 S.E.2d at 659.
N.C. Gen. Stat. § 153A-221(a) requires that the Secretary of Health and Human Services “develop and publish minimum standards for the operation of local confinement facilities,” including standards for “[m]edical care for prisoners, including mental health, mental retardation, and substance abuse services.” This statute creates an affirmative duty on Sheriffs operating county jails to provide medical and mental health services to jail inmates. We hold that under the rationale of Medley, this duty is nondelegable. “Where a principal has a nondelegable duty, one with whom the principal contracts to perform that' duty is as a matter of law an agent for purposes of applying the doctrine of respondeat superior.” Medley, 330 N.C. at 845, 412 S.E.2d at 659. We further hold that the definition of “agent” for purposes of the crime of sexual activity by a custodian under N.C. Gen. Stat. § 14-27.7 is identical to that as set forth in Medley.
As a matter of law, defendant was acting as an agent of the Mecklenburg County Sheriff at the time the crimes of sexual activity by a custodian and attempted sexual activity by a custodian were committed. Thus, the trial court did not abuse its discretion in refusing to admit the contract into evidence.
*105 [2] In his second argument, defendant contends that the trial court erred in prohibiting the cross-examination of the Mecklenburg County Sheriff and the health care services administrator of Prison Health Services regarding the contract between Prison Health Services and the Mecklenburg County Sheriff. We disagree.
We note that defendant contends in this assignment of error that the denial of his right to cross-examine the two witnesses at trial violated his constitutional right to confrontation. We have reviewed the portions of the transcript brought to our attention as being relevant to this assignment of error. Defendant raised no constitutional argument before the trial court. Constitutional errors not “raised and passed upon” at trial will not be considered for the first time on appeal. State v. Garcia, 358 N.C. 382, 410, 597 S.E.2d 724, 745 (2004) (citing State v. Watts, 357 N.C. 366, 372, 584 S.E.2d 740, 745 (2003); N.C. R. App. P. 10(b)(1) (2006)). We therefore decline to address defendant’s constitutional argument.
Defendant also contends in this assignment of error that the trial court’s prohibition of the cross-examination of. the two witnesses violated Rule 611 of the North Carolina Rules of Evidence, and we review this assignment for prejudicial error. N.C. Gen. Stat. § 15A-1443 (a) (2005).
“A trial judge’s rulings with respect to the scope of cross-examination will not be disturbed unless the defendant can show that the verdict was improperly influenced thereby. This rule is consistent with the requirement of G.S. 15A-1443(a) that a defendant has the burden of showing prejudice.” State v. Teeter, 85 N.C. App. 624, 636, 355 S.E.2d 804, 811 (1987) (internal citation omitted).
Defendant desired to cross-examine the two witnesses regarding the contract between Prison Health Services and the Mecklenburg County Sheriff. We have previously determined that the trial court properly excluded evidence of the contract at trial. Therefore, defendant cannot show any prejudice resulting from the trial court’s ruling. Defendant’s assignment of error is without merit.
NO ERROR.
