The client inquires what the positive result from the potassium hydroxide (KOH) test indicates. Which of the following is an accurate response by the nurse?
You have a virus.
You have a fungal infection.
You have a bacterial infection.
You have cancer.
The Correct Answer is B
Choice A Reason: A virus is not detected by the KOH test, which is used to diagnose fungal infections of the skin, hair, or nails. A virus can be detected by other tests, such as polymerase chain reaction (PCR) or viral culture.
Choice B Reason: A fungal infection is detected by the KOH test, which dissolves the skin cells and leaves behind the fungal elements that can be seen under a microscope. A fungal infection can cause symptoms such as itching, scaling, redness, or blisters.
Choice C Reason: A bacterial infection is not detected by the KOH test, which is specific for fungi. A bacterial infection can be detected by other tests, such as gram stain or culture.
Choice D Reason: Cancer is not detected by the KOH test, which is not a screening tool for malignancy. Cancer can be detected by other tests, such as biopsy or imaging.

Correct Answer is B
Explanation
Choice A Reason: This is correct because eating frequent small meals can help the client with IBS to avoid overloading the digestive system and triggering diarrhea. The nurse should advise the client to eat slowly and chew well, and avoid foods that are spicy, fatty, or gas-producing.
Choice B Reason: This is incorrect because increasing the intake of leafy greens and other sources of dietary fiber can worsen diarrhea by increasing stool bulk and motility. The nurse should advise the client to limit or avoid high-fiber foods, such as whole grains, fruits, vegetables, nuts, and seeds, during acute flare-ups of IBS. The client can gradually reintroduce fiber when the symptoms subside.
Choice C Reason: This is correct because increasing fluids can help the client with IBS to prevent dehydration and electrolyte imbalance caused by diarrhea. The nurse should advise the client to drink at least 8 glasses of water per day and avoid caffeinated, alcoholic, or carbonated beverages that can irritate the bowel or cause gas.
Choice D Reason: This is correct because taking prescribed medications on schedule can help the client with IBS to regulate bowel patterns and reduce diarrhea. The nurse should instruct the client on how to use medications, such as antidiarrheals, antispasmodics, or probiotics, as ordered by the provider. The nurse should also monitor the client for any adverse effects or interactions of the medications.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because earphones are not used in the Rinne test. The Rinne test compares air conduction and bone conduction of sound using a tuning fork.
Choice B Reason: This is incorrect because electrodes are not used in the Rinne test. Electrodes are used in electroencephalography (EEG), which measures brain activity.
Choice C Reason: This is incorrect because a probe is not used in the Rinne test. A probe is used in tympanometry, which measures the pressure and mobility of the eardrum.
Choice D Reason: This is correct because a tuning fork is used in the Rinne test. The tuning fork is placed on the mastoid process behind the ear and then moved near the ear canal to compare the sound perception.
