Gаrland Moore complains of injuries he alleged were caused by a nurse negligently injecting him with medicine intravenously instead of intramuscularly in the prescribed manner. After Moore rested his case, the district court entered judgment upon motions for dirеcted verdicts in favor of Dr. William Guthrie, Moore’s attending physician, and Guthrie Hospital, where Moore was a patient. We hold that the evidence conclusively shows the doctor was free of fault and affirm the district court’s judgment in favor of him. Moorе’s case against the hospital stands upon a different footing. The Seventh Amendment requires that this claim must be submitted to the jury, for the evidence against the hospital — viewed in the light most favorable to Moore — affords a rational choice for competing inferences. Atlantic Coast Line R. R. v. Truett,
I.
In considering the case against Dr. Guthrie, we start with the proposition: “A
prima facie
case of medical
*368
malpractice must normally consist of evidence which establishes the applicable standard of care, demonstrates that this standard has been violated, and develops a causal relationship between the violation and the harm complained of.” Kosberg v. Washington Hospital Center, Inc.,
II.
Under West Virginia law a private hospital may be held liable for injury to a patient resulting from the negligence of nurses employed by it. Duling v. Bluefield Sanitarium, Inc.,
Without contradiction, expert witnesses testified that an injection of chymar into the bloodstream is improper. On the record before us, proof of an intravenous injection would establish negligence, especially in the light of Dr. Guthrie’s specific instructions for intramuscular injеction. There is no dispute that the nurse employed by the hospital gave the injection. The principal issues, therefore, are simple questions of fact: did an injection introduce the medicine *369 in the bloodstream, and did this cause the plaintiff’s injuries?
In support of its motion for a directed verdict, the hospital urges that evidence disclosed that Moore’s injuries could have resulted either from an intravenous injection or from other causes over which the nurse had no control. It relies uрon the rule that where the plaintiff's evidence gives equal support to each of two inconsistent inferences for one of which the defendant is not responsible, judgment must be entered for the defendant. See Pennsylvania R.R. v. Chamberlain,
Moore was admitted to the hospital on November 29, 1962 for a hernia correction, which was satisfactorily performed on November 30. The hospital records show that he was given penicillin on November 30 through December 4, and chymar was prescribed on December 3 and December 4. Both drugs were to be administered intramuscularly. The records also show that penicillin and chymar were injected at 9 A.M., December 4, and that at 9 A.M. Moore had a grand mal seizure.
Moore introduсed evidence that an intravenous injection of chymar could bring on an immediate reaction or seizure but that an intramuscular injection would not cause a reaction for five or ten minutes. Another of his expert witnesses testified the reaction from an intramuscular injection would take from one to three hours.
A doctor called by Moore testified that the instantaneous reaction reported by the hospital indicated that the injection was given improperly and that the only cause of Moore’s injury was injection of the medicine into the bloodstream. This opinion is evidence to support the allegations that the medicine was negligently injected and that this negligence was the proximate cause of Moorе’s injury. The opinion was not conclusively discredited because the doctor in answering a question from the court conceded there would be no connection between Moore’s injuries and an intramuscular injection. 4 Although the doctor accepted the court’s assumption of an intramuscular injection for the pur *370 pose of answering the question, he was unwavering in his belief that an intramuscular injection could not have produced the instantaneous result reported in the hospital records.
The hospital also urges that Moore’s grand mal seizure could have been caused by other conditions. It points to cross-examination of one of Moore’s experts:
“Q. [W]ill you just look at the jury when you give an answer, what are the — some of the precipitating causes of a grand malseizure ?
“A. Of course, the most common thing is epilepsy, which is by far the commonest thing of grand mal-seizures. Probably the next most common thing is brain tumor, and probably the next is stroke. And then we come down the line to things such as anoxia, instant reaction, low blood sugar will do it. Those are the most common things.”
It is apparent that this testimony is insufficient to defeat Moore's claim. The doctor was not asked whether Moore’s grand mal seizure was caused by the mаladies that he mentioned. He was replying to a general question in a general way without specifically referring to Moore.
The defendants also urge that Moore’s seizure could have resulted from anaphylatic reaction to pеnicillin injected intramuscularly. There are two reasons why this theory should not foreclose the jury from consideration of Moore's case. First, Moore’s doctor testified that an anaphylatic reaction could not result from one injection of penicillin. It could result from a second injection, but in his opinion an interval of about ten days between the first injection and a following injection was required to allow the production of antibodies leading to a reaction. He added thаt a reaction had been reported after an interval of five or six days. Moore’s seizure occurred only four days after his initial injection. Secondly, the anaphylatic reaction from successive intramuscular injections would not be instantaneous. If the penicillin were given intramuscularly, at least five or ten minutes, and possibly as long as one to three hours, would be required for absorption and reaction. On the basis of this testimony, a reasonable inference can be drawn that Moore’s seizure was not caused by successive intramuscular injections of penicillin.
The hospital’s reliance on Swanson v. Wiesenfeld,
Finally, the hospital urges that Moore’s expert witness shоuld not have been allowed to express an opinion that an intravenous injection caused Moore’s injury, because the opinion in part was based upon medical reports concerning Moore which were not in evidence. It is not clear from the record, however, just what information the doctor obtained from the fugitive medical reports. The district judge took the hospital’s objection under advisement and made no rul *371 ing upon it. The absence of the medical reports from the record prevents us from determining whether the facts they disclosed were introduced into evidence by some other means. In any event, the question is not likely to arise at retrial. The medical reports may be made a part of the record if they are admissible, or the authors may be deposed, or the information contained in these reports may also be found in other reports and testimony.
The judgment in favor of Dr. William Guthrie is affirmed. The judgment in favor of Guthrie Hospital, Inc., is vacated, and this action is remanded for retrial.

“Tlie Witness: If it were established that it was nothing but intramuscularly then the whole sequence of events would have to be coincidents which werе followed with the neurological findings, but the information that I have from my record and on which I make my opinion was that at 9:00 o’clock he was given this injection and at 9:00 o’clock, or as close to it as possible, he had the reaction that has bеen described.
“The Court: I know, but you’re assuming that the injection was intravenously.
“The Witness: It got into the bloodstream, yes, sir.
“The Court: Now, assuming that it was not intravenously but it was given intramuscularly like the doctor ordered, then what would you have to say as to whether or not there is any causal connection between the giving of the injection and Mr. Moore's present condition?
“The Witness: Then I would say there was no connection.”
