NurseDive Free Nursing Practice Question
The physician suspects a client has a dermatological infection. Which of the following diagnostics will be ordered to observe color changes to the skin using an ultraviolet light source?
A. Culture
Reason: Culture is not a diagnostic test that uses an ultraviolet light source, but a laboratory test that involves growing microorganisms from a sample of body fluid or tissue. Culture can help identify the type and sensitivity of the infection-causing agent.
B. KOH
Reason: KOH is not a diagnostic test that uses an ultraviolet light source, but a chemical test that involves applying potassium hydroxide to a sample of skin, hair, or nail. KOH can help diagnose fungal infections by dissolving the keratin and revealing the fungal elements under a microscope.
C. Diascopy
Reason: Diascopy is not a diagnostic test that uses an ultraviolet light source, but a physical test that involves applying pressure to a lesion with a glass slide or lens. Diascopy can help differentiate between blanchable and non-blanchable lesions, such as erythema or petechiae.
D. Wood's
Reason: Wood's is a diagnostic test that uses an ultraviolet light source, also known as a Wood's lamp or black light. Wood's can help observe color changes to the skin that are not visible under normal light, such as fluorescence or hypopigmentation. Wood's can help diagnose conditions such as tinea capitis, vitiligo, or erythrasma.

A nurse is caring for a client who is postoperative from glaucoma surgery in the right eye. Which of the following will the nurse include in the postoperative education to the client? (Select all that apply.)
A. You will be able to drive home right after you have voided.
Choice A reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not drive home after glaucoma surgery, as they will have reduced vision and increased sensitivity to light in the operated eye. The nurse should advise the client to arrange for someone else to drive them home.
B. Lay on the right side when going to bed.
Choice B reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not lay on the right side when going to bed, as this can put pressure on the operated eye and increase the risk of bleeding or infection. The nurse should advise the client to sleep on their back or on their left side.
C. Report flashing lights.
Choice C reason: This is correct because the nurse should include this in the postoperative education to the client.

D. Nap on your left side when you get home.
Choice D reason: This is incorrect because the nurse should not include this in the postoperative education to the client.

The nurse should advise the client to elevate their head at least 30 degrees when resting.
E. Avoid housework like vacuuming.
Choice E reason: This is correct because the nurse should include this in the postoperative education to the client. The client should avoid housework like vacuuming, as this can cause bending, lifting, or straining that can increase intraocular pressure and affect wound healing.

F. Flashes of light are normal.
Choice F reason: This is correct because the nurse should include this in the postoperative education to the client. The client may see flashes of light in the operated eye, as this is a normal phenomenon caused by stimulation of the retina by gas bubbles or fluid shifts.

A nurse caring for a client with acute peritonitis reviews the physician's orders. The orders include an NPO diet, insertion of a nasogastric tube set to low intermittent suction, and IV fluids at 50 mL per hour. When asked why he will need the NG tube, what is the nurse's best reply?
A. To administer medications and electrolytes
Reason: To administer medications and electrolytes is not the best reply for why the client will need the NG tube, because this is not the primary purpose of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Medications and electrolytes can be given through the IV route.
B. To dilate the stomach as a presurgical preparation
Reason: To dilate the stomach as a presurgical preparation is not the best reply for why the client will need the NG tube, because this is not a valid indication for the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Dilation of the stomach is not a goal of presurgical preparation, but rather an adverse effect of gastric obstruction.
C. You will not be able to eat for several days
Reason: You will not be able to eat for several days is not the best reply for why the client will need the NG tube, because this is not a complete or accurate explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. The client will not be able to eat for several days because of the NPO diet, which is necessary to rest the inflamed peritoneum and reduce the risk of complications.
D. To remove secretions and decompress your stomach
Reason: To remove secretions and decompress your stomach is the best reply for why the client will need the NG tube, because this is a clear and correct explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration, which are common symptoms of acute peritonitis. By removing secretions and decompressing the stomach, the NG tube can reduce pain, inflammation, and infection in the abdominal cavity.
