*452OPINION
JOHN G. HILL, Senior Justice(Assigned).
Rebecca Ann Shaw appeals her conviction by a jury of the offense of recklessly causing serious bodily injury to a child. The jury assessed her punishment at twenty years in the Texas Department of Criminal Justice, Institutional Division, and a fine of $10,000. She asserts in a single point that the trial court erred in refusing to submit her timely requested defense to prosecution of injury to a child, that the act or omission consisted of emergency medical care administered in good faith and with reasonable care by a person not licensed in the healing arts. We affirm.
As a general rule, an accused has the right to an instruction on any defensive issue raised by the evidence, whether such evidence is strong or weak, unimpeaehed or contradicted, and regardless of what the trial court may or may not think about the credibility of the evidence. Miller v. State, 815 S.W.2d 582, 585 (Tex.Crim.App.1991). An element of the defense is “raised” if, viewing the evidence in the light most favorable to the defendant, there is evidence that a rational juror could accept as sufficient to prove that element. See Mathews v. United States, 485 U.S. 58, 63, 108 S.Ct. 883, 887, 99 L.Ed.2d 54, 61 (1988); United States v. Maseratti, 1 F.3d 330, 336 (5th Cir.1993); Ferrel v. State, 55 S.W.3d 586, 591 (Tex.Crim.App.2001); Johnson v. State, 157 S.W.3d 48, 50 (Tex.App.-Waco 2004, no pet.); Wilson v. State, 111 S.W.2d 823, 825 (Tex.App.-Austin 1989), aff'd, 853 S.W.2d 547 (Tex.Crim.App.1993). Whether the defense is raised by the evidence is always a question of law. Id.
The dissent questions our reliance on a rational-juror test as a basis for determining whether defensive evidence is sufficient to require an instruction, arguing that the use of such a test wrongly allows the court to weigh the relative credibility of the evidence. We submit that the test assumes the credibility of the evidence supporting the defense, then determines whether it is evidence that a rational juror could accept as sufficient to prove the elements of the defense.
The dissent also suggests that a rational-juror test is in conflict with the concept that an accused has the right to an instruction on any defense issue raised by the evidence, regardless of its strength or credibility. Rather, the rational-juror test is the standard by which we determine whether that evidence has raised a defensive issue. Our opinion is not in conflict with opinions of the Texas Court of Criminal Appeals or of this court that hold that a defendant is entitled to an instruction when a defensive issue has been raised by the evidence, regardless of its strength or credibility, but do not explicitly set forth the standard by which the court determines when the defensive issue has been raised. The real alternative standard to that which we have set forth is that a defendant is entitled to an instruction on a defensive issue even if the evidence would not rationally support a finding of the elements of the defense. We respectfully decline to adopt that standard.
It is a defense to prosecution for injury to a child that the act or omission consisted of emergency medical care administered in good faith and with reasonable care by a person not licensed in the healing arts. Tex. Pen.Code Ann. § 22.04(k)(l)(B) (Vernon 2003). Shaw was convicted of recklessly causing serious bodily injury to a child by shaking the child and causing his head to strike an unknown object. We will first see if there is evidence from which a rational juror *453could conclude that Shaw’s shaking the child and causing his head to strike an unknown object consisted of emergency medical care administered in good faith and with reasonable care.
Shaw testified that on the day in question she had been caring for her grandchild in her home for almost a month. She said that she called 911 because the child was in his crib having labored breathing. She stated that when she saw the child having breathing problems, she dropped the clothing she had in her hand and ran to his crib, picked him up, and called to him, but he did not respond. She acknowledged that she had performed CPR before this occasion.
She testified that she went over and “went like this” and picked up the child “like this,” called the child’s name, and “his little head went over.” She stated that she ran through the house to get the baby’s heart monitor, while holding the baby “like this.” She indicated that rather than hooking the child up to the heart monitor, she got a wet rag and patted the child with it “like this.” In getting the rag wet, she could not get the faucet on so she switched arms “like this.”
Shaw testified that she took the child to the bedroom, placed him on the bed with the heart monitor, and grabbed the phone. She related that after trying to call her landlord, she called 911. She stated that she was instructed by the 911 dispatcher. She indicated that she was told to do rescue breathing and tip the child’s head back. She said she tipped the child’s head back and blew in his mouth.
Shaw testified that she felt that she was not getting a seal on the child’s nose with her cheek, and she could not open her mouth big enough to get around his mouth and his nose. She stated that when the paramedics were on their way and she realized the door was locked, she grabbed the child underneath “like this,” while running through the house to unlock it. According to Shaw, after unlocking the door, she returned to the phone where she started to do CPR when the paramedics told her to do it. Shaw testified that at first two police officers showed up and performed CPR. She indicated that the paramedics started working on the child after they arrived. The 911 tape reflected the panic and stress of Shaw’s voice as she responded to the crisis.
Dr. Angel Hernandez, a pediatric neurologist, testified that on the evening the child was brought to the hospital, he was called in to help evaluate the child. After conducting several tests, Dr. Hernandez concluded that bleeding in the child’s brain was caused by shaking the baby or by hitting it with something in the head. He insisted that such an injury could have occurred within minutes or no more than four to six hours previously. In a consultation report dated the day of the child’s being taken to the hospital, Dr. Hernandez concluded that certain bleeding in the brain was probably the result of aggressive, cardio-pulmonary resuscitation, but that he could not rule out the possibility of non-accidental trauma.
In summary, Shaw testified how she ran through the house with the baby and how she performed CPR on the baby, while one of the attending physicians, at least initially, thought that the injury was the result of aggressive cardio-pulmonary resuscitation. That same physician testified that in his opinion shaking the baby or hitting it in the head caused the injury. The emergency medical care for the baby was CPR. There was no testimony regarding how either the responding police officers or the responding paramedics conducted CPR. There is no evidence that shaking a baby or causing its head to hit an object, even including a bed, is reasonable in conduct*454ing CPR on an infant. Therefore, assuming there is evidence that Shaw shook the baby and hit its head against an object, which might include the bed, there is no evidence from which a rational juror could conclude that such action was a reasonable way to conduct infant CPR. Inasmuch as the average jury would be unfamiliar with the appropriate conduct of infant CPR, it would not be in a position to judge whether Shaw’s actions were reasonable under the circumstances. If one were to suggest that the jury could make such a determination through common knowledge, common knowledge would be that shaking a baby and hitting its head against an object, even a bed, would not be a reasonable way to conduct CPR. We hold that a rational juror could not conclude from this evidence that shaking the baby or causing its head to hit an unknown object consisted of emergency medical care administered in good faith and with reasonable care.
We next consider whether there is evidence from which a reasonable juror might conclude that Shaw was a person not licensed in the healing arts. “Healing arts” is not defined in section 22.04 of the Texas Penal Code. See Tex. Pen.Code ANN. § 22.04 (Vernon 2003). We must therefore construe the meaning of the term as it is contained in section 22.04(k)(l)(B) of the Code. The provisions of the Penal Code are to be construed according to the fair import of their terms, to promote justice and effect the objectives of the code. Tex. Pen.Code ÁNN. § 1.05(a) (Vernon 2003). Unless a different construction is required by the context, sections 311.011, 311.012, 311.014, 311.015 and 311.021 through 311.032 of the Government Code (Code Construction Act), apply to the construction of the Penal Code. Tex. Pen.Code Ann. § 1.05(b) (Vernon 2003). We are to read words and phrases in context and construe them according to the rules of grammar and common usage. Tex. Gov’t Code Ann. § 311.011(a) (Vernon 2005). We are to construe words and phrases that have acquired a technical or particular meaning, whether by legislative definition or otherwise, according to that meaning. Tex. GoV t Code Ann. § 311.011(b) (Vernon 2005).
Whether or not this statute is considered ambiguous on its face, we may consider, among other matters, the: (1) object sought to be attained; (2) circumstances under which the statute was enacted; (3) legislative history; (4) common law or former statutory provisions, including laws on the same or similar subjects; (5) consequences of a particular construction; (6) administrative construction of the statute; and (7) title (caption), preamble, and emergency provision. Tex. Gov5 t Code Ann. § 311.023 (Vernon 2005).
Shaw testified that at the time she became totally responsible for the care of the child, she was working as .a pediatrician’s medical assistant, taking care of all the pediatric care. She outlined her duties and responsibilities under that pediatrician, as “everything required to take care of all the children in her office, immunizations, checking them in, weighing them.” When asked what the licensing was for becoming a medical assistant to a pediatrician, she said that one has to go through school and become licensed. She indicated that she went through the school and graduated.
A person may not practice as a physician assistant unless the person is licensed. Tex. Occ.Code Ann. § 204.151 (Vernon 2004). We are not aware of any medical assistants, other than physician assistants and nurses, who are required to be licensed. Since Shaw does not appear to be a nurse, the only reasonable conclusion that may be drawn from her testimony is that she is licensed as a physician assistant. The question we must determine is *455whether a physician assistant is a person licensed in the healing arts within the meaning of section 22.04 of the Texas Penal Code.
“Healing” has been defined as “tending to heal or cure.” Webster’s Third New International Dictionary of the English Language Unabridged 1043 (Merriam-Webster, Inc.1993). “Art” has been defined as “the power of performing certain actions esp. as acquired by experience, study, or observation.” Id. at 22. Internet research through the Google search engine reveals that the term “healing arts” in common usage includes a broad range from physicians to massage therapists and crystal healers. The legislature, in the Healing Art Identification Act, broadly defined the “healing art” as “any system, treatment, operation, diagnosis, prescription, or practice to ascertain, cure, relieve, adjust, or correct a human disease, injury, or unhealthy or abnormal physical or mental condition.” Tex. OCC.Code Ann. § 104.002 (Vernon 2004).
Having broadly defined “healing art,” the legislature in the next section of the Healing Art Identification Act includes a list of legally required identifications that must be used by certain practitioners of the healing arts. See id. § 104.003 (Vernon 2004). Those include physicians, dentists, chiropractors, optometrists, and podiatrists. There is no stated identification in this section for physician assistants. Id. All of these medical professionals are licensed; however, in another statute the legislature has subsequently provided that even certified medical workers are involved in the healing arts. See Tex. Civ. PRAC. & Rem.Code Ann. § 74.152 (Vernon 2005).
Therefore, given the broad definition of the healing arts, and its broad usage in our society; given the fact that physicians are practitioners of the healing art and physician assistants perform many of the same practices as a physician, acting under the supervision of a physician; and given that the legislature has subsequently provided that even certified medical workers are involved in the healing arts, we hold that a physician assistant is, for the purpose of the defense to this prosecution, a person licensed in the healing arts. Consequently, Shaw, who is a licensed physician assistant, is licensed in the healing arts with respect to the purpose of the defense to this prosecution. We recognize the possibility that, despite her testimony, Shaw may be an unlicensed medical assistant who performs only routine tasks in the office to assist the physician. However, in view of Shaw’s testimony that she was licensed, and her broad testimony as to her duties, a rational juror would be required to resort to speculation in order to make such a determination.
With respect to this aspect of the issue, Shaw relies on the cases of Moore v. Trevino, 94 S.W.3d 723 (Tex.App.-San Antonio 2002, pet. denied), and Hernandez v. Lukefahr, 879 S.W.2d 137 (Tex.App.-Houston [14th Dist.] 1994, no writ). We find both cases to be distinguishable.
In Moore, the court held, in construing the former section 74.002 of the Good Samaritan Act,1 that emergency medical service personnel are not persons licensed in the healing arts within the meaning of that statute. Moore, 94 S.W.3d at 727. Section 74.002 provided that persons not licensed in the healing arts who in good faith administer emergency care as emergency medical service personnel were not *456liable in civil damages for an act performed in administering the care unless the act was willfully or wantonly negligent, without regard to whether the care was provided for or in expectation of remuneration.2 Civil Practice & Remedies Code, 69th Leg., R.S., ch. 959, § 1, sec. 74.002, 1985 Tex. Gen. Laws 3242, 3299 (amended 2003) (current version at Tex. Civ. Prac. & Rem.Code AnN. § 74.152).
We first note that the statute by its terms leads one to the conclusion that the legislature did not intend that emergency medical service personnel be considered as persons licensed in the healing arts. Id. The court reached its conclusion on the basis that emergency medical service personnel are not engaged in the practice of medicine and are not health care providers. See Moore, 94 S.W.3d at 727. The second reason for the court’s decision is that emergency medical personnel are not listed in the listing of healing arts in the Healing Art Identification Act and were not engaged in the practice of medicine or an equivalent practice in other statutes. Id.
In the case at bar, Shaw, as a licensed physician assistant, is engaged in the practice of medicine under the supervision of a physician and, unlike an emergency medical technician, is a healthcare provider. See Tex. Occ.Code Ann. §§ 152.003(a)(l)(J), 204.204 (Vernon 2004). Although not listed in the Healing Art Identification Act, physician assistants are daily engaged in the practice of medicine or “an equivalent practice in other statutes.” As we have previously noted, “healing arts” has been applied by the legislature to even certified medical workers who would necessarily not be among those listed in the Act. Therefore, we find that Moore is distinguishable and is not in conflict with this decision.
In Hernandez, the court held that a physician, who did not fall into one of the exceptions listed in the former section 74.001 of the Good Samaritan Act,3 was excluded from liability under that statute for emergency care that he administered unless his actions were willfully or wantonly negligent. See Hernandez, 879 S.W.2d at 140-42. Since that statute applied to any person who in good faith administered emergency care at the scene of an emergency or in a hospital and who did not fall within one of the four exceptions found in the statute, this holding is of no assistance in our determination of whether a physician assistant is licensed in the healing arts. See id. As previously noted, we find Hernandez to be distinguishable from the case at bar because it does not involve a *457determination of who is licensed in the healing arts. We do not find Hernandez to be in any way inconsistent with our opinion. Because a rational juror could not have found that Shaw’s conduct in shaking the baby and hitting its head against an object was reasonable emergency medical care or that Shaw was not licensed in the healing arts, the defense in question was not raised. Consequently, the trial court did not err in refusing to give the instruction requested by Shaw. We overrule Shaw’s sole point on appeal.
The judgment is affirmed.
