Plaintiff, a child of 10 years, was admitted to defendant hospital for the removal of tonsils and adenoids. She sustained certain injuries prior to surgery and sued defendant for damages caused by its alleged negligence. Although the cause involved four days of trial, and the jury had deliberated only less than three hours, the trial judge discharged the jury upon its failure to agree on a verdict. Motions for nonsuit and a directed verdict having been previously denied, defendant moved under section 630, Code of Civil Procedure, for judgment in its favor. The motion was granted and plaintiff has appealed from the judgment which followed.
Motions under section 630, Code of Civil Procedure, are governed by the same rules applicable to motions for nonsuit and directed verdict. Thus, they may properly be granted “when and only when, disregarding conflicting evidence, and giving to plaintiff’s evidence all the value to which it is legally entitled, indulging in every legitimate inference which may be drawn from that evidence, the result is a determination that there is no evidence of sufficient substantiality to support a verdict in favor of plaintiff”
(Carpenter
v.
Atchison T. & S. F. Ry. Co.,
Plaintiff, 10 years old, entered defendant hospital in mid-afternoon of December 26, 1955. She was assigned to the second floor and placed in a hospital bed of standard size equipped with side rails extending about 15 inches above the bed. Three nurses, all assigned to the 3 p.m.-ll p.m. shift were on duty. Of these three, Nurse Sallee was in charge and, although licensed and registered in Idaho, she had not yet *90 received her license under this state’s reciprocity law; the other two nurses on duty were registered and licensed in California.
There is no record on the temperature and pulse chart that, upon admission, plaintiff’s pulse was taken. However, later she was given a physical examination by Dr. Martin, her anesthesiologist, who prescribed the following preoperative medication : one and one-half grains of nembutal to be administered at the hour of sleep, and again at 6 a.m., three-fourths of a grain to be repeated if needed; 50 milligrams of demoral and one one-fiftieth grain of atropine at 7 a.m. At 9:15 p.m., Nurse Sallee administered the first dosage of nembutal.
At 11 o’clock, Nurse Detter came on duty. She was registered in Great Britain, but not in California and had been employed by defendant since 1951, during which time she had been regularly giving injections. At 11:10 p. m., finding plaintiff outside her room, she put her back in bed; at 11:30 p.m., after checking Dr. Martin’s preoperative orders, she gave plaintiff three-fourths of a grain of nembutal. Plaintiff’s pulse and temperature were not taken thereafter, but Nurse Detter subsequently advised her night supervisor of the additional medication administered. Between 5 :30 a.m. and 6 a.m., plaintiff was taken to the bathroom by an attendant nurse after first being clothed with a cap and gown for surgery; at that time she was sleepy and under sedation. Upon being returned to her bed, the side rails were put up. At 6 o’clock, plaintiff was awake and Nurse Detter gave her a grain and a half of nembutal. At 6:15, she was still awake and talked to the night supervisor. At 7, plaintiff appeared to be asleep again and Nurse Detter then injected intramuscularly the prescribed dosages of demoral and atropine. Plaintiff was not awakened although her muscles reacted to the stimulus. When Nurse Detter last saw plaintiff at 7 a.m., she was under the influence of hypnotics and appeared to be asleep.
At 7:15 plaintiff’s temperature was taken by a registered nurse who had just come on duty; she was then sleeping quietly, her color was good, and she was breathing normally. At approximately the same time her pulse was taken by another registered nurse who described her condition as normal for a patient under preoperative medication. Plaintiff’s pulse was noted to be 104, which, according to the nurse, was within normal range under the circumstances, and she did not report the fact to her supervisor. Both of these registered nurses *91 testified that the bed's side rails were up, as did plaintiff’s father who looked into his daughter’s room and stated that she did not appear to be restless.
At 7:23 a.m., plaintiff fell out of her bed, sustaining a lineal fracture of the jaw. When plaintiff was found on the floor the side rails of her bed were still up. She testified that when she returned from the bathroom at 6 o’clock a.m., she went back to sleep and could recall nothing, including the fall, until 8 o’clock. Dr. Martin examined plaintiff at 7:35 a.m., and stated she was then conscious, although sedated, and responded to his questions. He further testified that he did not observe any condition which indicated that plaintiff had any side effects from the medication administered, such as reaction, allergy or susceptibility. At 11:40 a.m., however, his progress report disclosing that plaintiff was then complaining of headache and seeing double “which is not incompatible with a hangover from medication, however it could be due to the fall.” The hospital records also included an entry by another doctor that immediately after the fall plaintiff complained of double vision.
The chief contentions urged by appellant concern the sufficiency of the evidence, aided by the doctrine of res ipsa loquitur, to support a judgment in her favor; and error by the trial court in refusing proffered instructions on the care required of respondent hospital and the application thereto of res ipsa loquitur. Supportive of her claims that the evidence was sufficient to sustain a verdict against respondent, appellant argues that the hospital was guilty of negligence as a matter of law in violating certain statutes governing the nursing profession and the administration of narcotic and hypnotic drugs; and that jury questions were raised by evidence establishing, or tending to establish, that respondent and its employees failed to furnish the care and facilities commensurate to her needs.
We first consider whether the law prohibits the furnishing of drugs by nurses in the category of Nurses Sallee and Detter. Section 2725, Business and Professions Code, defines the practice of nursing as “the performing of professional services requiring technical skills and specific knowledge . . . acquired in an accredited school . . . and practiced in conjunction with curative and preventive medicine as prescribed by a licensed physician and the application of such nursing procedures as involve understanding cause and effect in order to safeguard life and health of a patient and *92 others.” It is therein further declared that “ (A professional nurse ... is a person who has met all the legal requirements for licensing as a registered nurse in the State ...” Section 2732 of the same code provides that no person shall practice nursing as defined by section 2725 without a license. Next, and with reference to the control of hypnotic drugs (nembutal being in that category) by a hospital not employing a pharmacist, section 4225, Business and Professions Code, specifies that “ (t)he supply is to be made available to a registered nurse, for administration, on the order or direction of a physician to patients registered in the hospital, or to emergency cases under treatment in the hospital.” Appellant contends that by virtue of the foregoing statutes only a California registered nurse could administer the drugs prescribed for her, and neither Nurse Sallee nor Nurse Better having been licensed in this state, both were guilty of negligence per se.
Without going further into the matter of whether both nurses technically may have violated one or more statutes by the administration of the drugs prescribed, it does not follow that if such violation be deemed to exist, it must be considered as negligence
per se.
While it is elementary that an act in violation of a statute is negligence as a matter of law, it is also established that unusual conditions may be shown to excuse or justify the violation. “Each violation must be considered in connection with the surrounding circumstances”
(Curtis
v.
Q. R. S. Neon Corp. Ltd.,
Nurse Sallee, who administered the first dosage of nembutal, was registered in Idaho; Nurse Better, who furnished the remainder of the preoperative medication, had been registered in Great Britain since 1931 and had given many injections of the type in question. Dr. Martin, without specifying that his statement was limited to California registered
*93
nurses, testified that it was standard practice in the community for nurses to give medication pursuant to doctors’ orders. However, the doctrine of customary usage does not apply to the question of legal duty under the law of negligence (Ro
binet
v.
Hawks,
It is well established that before the violation of a statute creates any liability, it must be the proximate cause of the injury complained of
(Hickenbottom
v.
Jeppesen,
Appellant has presented nothing to distinguish her case from the rules and reasoning found in the foregoing decisions except the reassertion that it was for the jury to decide whether the administration of the prescribed drugs by an unlicensed California registered nurse proximately contributed to her injuries. Whether such causation exists is a question of fact except when reasonable men can draw but one inference from the facts
(Figlia
v.
Wisner,
Related to the matters just discussed and determined is appellant’s additional claim that respondent was negligent in its selection of unlicensed nurses to administer dangerous drugs and that it negligently supervised these employees whose alleged inaction in the presence of danger signals proximately caused the injuries sustained. There is authority generally for the first of the foregoing contentions; thus, liability may attach to a hospital if it negligently employs an incapable nurse through whose carelessness or lack of ability in the course of her duties the patient is injured
(England
v.
Hospital of Good Samaritan,
There can hardly be any doubt that appellant possessed some special susceptibility either to the drugs administered or to the dosage prescribed. The claim is advanced that there was evidence forewarning respondent’s employees which would have moved a reasonably intelligent attendant to take necessary precautions to prevent what thereafter occurred. Dr. Martin, who was not named as a defendant, *96 testified that he examined appellant before the preoperative medication was prescribed, checked her history, looked at her throat, listened to her heart and lungs, and took her blood pressure and pulse. He found that she was apprehensive and jittery, but otherwise perfectly normal. Edna Toutz, a California registered nurse, stated that it is not ordinary and customary practice in hospitals to take a child’s pulse on admission because the variation is so great that it would not be significant in the case of a tonsillectomy. She further testified that she took appellant’s pulse at 7:15 a. m., and did not report the fact it was 104 because a child’s pulse varies more than an adult’s, and appellant’s pulse was within normal range in view of the anesthetic state in which she had been placed. Norma Ford, also a California registered nurse, stated that the preoperative medication was the standard, normal preoperative medication for a patient of appellant’s age and size. This view was concurred in by Dr. Martin, who also gave the following testimony: that his medication orders had been carried out; that a pulse of 104 for a child of appellant’s age and weight and with preoperative medication is not unusual and within normal limits and that the medication given was standard for a person in appellant’s age and weight category; that the side rails on appellant’s bed were standard size and that it was customary practice to place a child of appellant’s age in a regular bed, rather than in a crib or small bed; that the side rails should be kept up—(there is no claim that such precaution was not taken)—and if the patient shows any tendency to become disturbed, she should be watched but not restrained (to physically restrain a person would make him wilder), that he relied on the nurses to adhere to such practices and that he would not have administered an additional dosage of nembutal if appellant had exhibited any excitement or manifested an allergic reaction thereto. No expert testimony was introduced to negative the foregoing.
Based on the above facts, and other evidence either already narrated or of a cumulative character not necessary here to summarize, appellant argues that despite “all the classic signs of a drug reaction” respondent’s employees administered an excessive dosage of drugs, sufficient to “trigger” a latent susceptibility thereto; if not, they had notice or knowledge of facts reasonably indicating that she would be likely to harm herself unless preclusive measures were taken. Neither contention, in our opinion, has merit. A private
*97
hospital is not an insurer of a patient’s safety
(Gray
v.
Carter,
Likewise without merit is the contention that liability
*98
arose by virtue of respondent’s failure to beep proper hospital records; specifically, its omission to take and record appellant’s pulse and temperature upon her admission. We are asked in that respect to take judicial notice of Hospital Licensing Regulation Number 280, which assertedly governs. Again, however, any alleged violation of such a regulation becomes immaterial unless appellant can show that the same was a proximate cause of her injuries. In
Costa
v.
Regents of University of California,
Appellant’s next contention that she established a prima facie case by evidence which was sufficient to invoke in her favor the doctrine of res ipsa loquitur is a decisive one. The elements essential to the application of res ipsa loquitur, well settled by the decisions, are summarized in
Snyder
v.
Hollingbery,
In this case, conditions (b) and (c),
supra,
were obviously present and respondent does not appear to contend otherwise. The question is: Was (a) also present? “As a general rule, res ipsa loquitur is applicable where it appears
*99
that the accident is of such a nature that it can be said, in the light of past experience, that it
probably
was the result of negligence by someone and that the defendant is
probably
the one who is responsible.”
(Stanford
v.
Richmond Chase Co.,
Still our courts were reluctant to apply the doctrine of res ipsa loquitur under conditions in which medical testimony was given, the inference based on common knowledge being at the root of the res ipsa loquitur doctrine.
(Moore
v.
Belt,
Thereafter in
Bauer
v.
Otis,
Now it is well established that “ (I)n determining whether an accident was of such a nature that it probably was the result of negligence by someone, the courts have relied upon both (a) common knowledge and (b) the testimony of expert witnesses, as well as the circumstances relating to the accident in each particular case.
(Zentz
v.
Coca Cola Bottling Co.,
*102
We reiterate that Dr. Martin was not named a defendant, and appellant does not claim that he was acting as respondent’s agent. Under the theory of “collective control” however, as well as the doctor’s statement that he “relied” on them to maintain proper surveillance over his anesthetized patient, the duty devolved on respondent’s nurses to adhere to the standard of care required; but the rules of the Dierman ease are applicable to them only. After a careful examination of the record, we do not believe that respondent has shown that its care of appellant was “satisfactory in the sense that it covers all causes which due care on the part of defendant might have prevented.”
(Dierman
v.
Providence Hospital, supra,
Although wisely stated in
Salgo
v.
Leland Stanford etc. Board of Trustees,
It appears to us that the jury should have been permitted to decide whether proper preclusive measures were taken in the light of the circumstances at bar. Citing
Seneris
v.
Haas,
Appellant’s final contention relates to the trial court’s refusal to give a proffered instruction based on the doctrine of res ipsa loquitur. Since we have determined that the doctrine is here applicable, it was error for the court so to do.
For the foregoing reasons, the judgment is reversed.
White, P. J., concurred.
Fourt, J., dissented.
Respondent’s petition for a hearing by the Supreme Court was denied June 24, 1959.
