A client arrives to the emergency department complaining of acute onset of nausea with projectile vomiting. The nurse's assessment findings include high-pitched sounds in the left upper quadrant. Which gastrointestinal disorder is consistent with these findings?

Choice A reason: This is incorrect because using sign language when communicating with the client is not an appropriate action for the nurse to take. Sign language is a form of communication that uses hand gestures, facial expressions, and body movements. It is not a universal language and requires training and practice. The nurse should not assume that the client knows or prefers sign language unless they have indicated so.

Choice B reason: This is incorrect because speaking loudly and into the client's good ear is not an appropriate action for the nurse to take. Speaking loudly can distort the sound quality and cause discomfort or irritation to the client. Speaking into the client's good ear can also create a sense of imbalance and isolation. The nurse should speak at a normal volume and tone, and face the client directly.

Choice C reason: This is the correct answer because speaking directly to the client in a normal, clear voice is an appropriate action for the nurse to take. Speaking directly to the client can help them see the nurse's mouth movements and facial expressions, which can enhance understanding and communication. Speaking in a normal, clear voice can help convey the message clearly and respectfully.

Choice D reason: This is incorrect because sitting by the client's side and speaking very slowly is not an appropriate action for the nurse to take. Sitting by the client's side can make it difficult for them to see the nurse's face and hear their voice. Speaking very slowly can also make the message unclear and patronizing. The nurse should sit in front of the client and speak at a normal pace.

Choice A reason: This is incorrect because education about mastoidectomy is not relevant for a client with an upper respiratory infection. Mastoidectomy is a surgical procedure that removes part or all of the mastoid bone behind the ear, which can become infected or inflamed due to chronic or recurrent middle ear infections. The nurse should assess the client's ear for signs of mastoiditis, such as swelling, tenderness, or redness behind the ear, but mastoidectomy is not a common or first-line treatment for upper respiratory infection.
Choice B reason: This is incorrect because a referral for a hearing test is not necessary for a client with an upper respiratory infection. Hearing test is a diagnostic tool that measures how well a person can hear different sounds at different frequencies and intensities. The nurse should ask the client about any changes in hearing or tinnitus, which are possible complications of upper respiratory infection, but a hearing test is not a routine or urgent intervention for this condition.
Choice C reason: This is correct because education on the administration of oral antibiotics can help treat an upper respiratory infection. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Upper respiratory infections can be caused by various pathogens, such as viruses, bacteria, or fungi, but bacterial infections are more likely to cause fever, otalgia, or purulent nasal drainage. The nurse should instruct the client on how to take antibiotics as prescribed, such as dosage, frequency, duration, side effects, and interactions.
Choice D reason: This is incorrect because a prescription for an antifungal cream is not appropriate for a client
