A client calls the clinic and tells the nurse that he was bitten by a tick and is afraid he has Lyme disease. How long does the nurse understand that the tick must be attached to Lyme disease?
36 to 48 hours.
24 to 36 hours.
12 to 24 hours.
1 to 2 hours.
The Correct Answer is A
36 to 48 hours. Lyme disease is caused by the bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected black-legged ticks. The tick must be attached to the skin for at least 36 to 48 hours for the bacterium to be transmitted. The nurse should advise the client to seek medical attention promptly.
Choice B is incorrect because the tick must be attached for a longer duration of time for the bacterium to be transmitted.
Choice C is incorrect because the tick must be attached for a longer duration of time for the bacterium to be transmitted.
Choice D is incorrect because the tick must be attached for a longer duration of time for the bacterium to be transmitted.

Correct Answer is D
Explanation
Radiographic confirmation. Radiographic confirmation is the most reliable method to verify the placement of nasogastric tubes, and it is considered the gold standard. The nurse should use it to confirm placement initially and periodically to ensure that the tube is in the stomach and not in the lungs or esophagus.
Option A, placing the end of the tube in water and observing for bubbling, is incorrect because it is not a reliable method, and it can cause aspiration or infection.
Option B, using the auscultation technique, is incorrect because it can lead to misinterpretation of bowel sounds, and it is not reliable.
Option C, measuring pH of aspirates, is incorrect because it is not a reliable method, and it can be affected by several factors, including medications, stress, and nutritional status.
Correct Answer is D
Explanation
Radical excision. Treatment of melanoma includes surgical excision of the tumor with a margin of normal tissue to decrease the risk of recurrence. Radical excision involves the removal of the tumor, adjacent tissue, and possibly lymph nodes.
Option A, radiation therapy, may be used as an adjunct therapy, but it is not the primary treatment.
Option B, laser surgery, may be used to remove superficial lesions, but not for melanoma.
Option C, cryosurgery, is used to remove benign lesions or precancerous cells, but not for melanoma.
