Choose the correct answer I put my answers in CAPS:

1) Neither his physician nor the floor nurses HAVE been in to see him yet this morning.
2) On sponge and instrument count, it was noted that one of the sponges WAS missing.
3 The costs of his research WERE paid by the hospital.
4) Dr. Jack, with the assistance of Dr. Jill and Dr. Pail, IS performing the surgery.
5) Past medical history shws the patient's mother currently HAD breast cancer.
Thanks!

Everything looks good except #3, it is supposed to be Was.

Liz is wrong.

The subject, "costs," is plural so the plural verb, "were" is correct.

Lori -- number 5 is incorrect.

1) The correct answer is "have been" since we are referring to multiple people (the physician and the floor nurses).

To determine the correct answer, we need to identify the subject and the corresponding verb. In this sentence, the subject is "neither his physician nor the floor nurses." Since the subject is plural, the verb should also be plural. Therefore, the correct verb form is "have been."

2) The correct answer is "was" since we are referring to one missing sponge.

To determine the correct answer, we need to identify the subject and the corresponding verb. In this sentence, the subject is "one of the sponges." Since the subject is singular, the verb should also be singular. Therefore, the correct verb form is "was."

3) The correct answer is "were" since we are referring to multiple costs.

To determine the correct answer, we need to identify the subject and the corresponding verb. In this sentence, the subject is "the costs of his research." Since the subject is plural, the verb should also be plural. Therefore, the correct verb form is "were."

4) The correct answer is "is" since we are referring to Dr. Jack.

To determine the correct answer, we need to identify the subject and the corresponding verb. In this sentence, the subject is "Dr. Jack." Since the subject is singular, the verb should also be singular. Therefore, the correct verb form is "is."

5) The correct answer is "has" since the patient's mother currently has breast cancer.

To determine the correct answer, we need to identify the subject and the corresponding verb. In this sentence, the subject is "the patient's mother." Since the subject is singular, the verb should also be singular. Therefore, the correct verb form is "has."
