The nurse is teaching a female client about ways to prevent a migraine. Which of the following information should the nurse include in the teaching?.

A. Magnesium hydroxide can interfere with the absorption of levothyroxine (Synthroid) and reduce its effectiveness. The nurse should notify the healthcare provider if the client is taking magnesium hydroxide or any other antacid that contains magnesium, calcium, or aluminum because these can decrease the absorption of levothyroxine.
B. While amitriptyline (an antidepressant) may interact with other medications, it does not typically interfere with levothyroxine. However, the nurse should always be cautious about potential interactions, especially with medications that affect the central nervous system.
C. Acetaminophen (Tylenol) does not typically interact with levothyroxine. It is safe to take acetaminophen while on levothyroxine.
D. Gabapentin (Neurontin) does not generally interfere with levothyroxine absorption or action. However, as with any medication, the nurse should be aware of other potential interactions based on the client’s overall health.

A. It is generally recommended to discard the first drop of blood when testing with a glucometer because it may be diluted with tissue fluid, leading to inaccurate results. The second drop should be used for the sample.
B. The center of the fingertip should be avoided for testing because it contains more nerve endings and can be more painful. It is better to poke the sides of the fingertip for a less painful experience.
C. A cold compress may cause blood vessels to constrict, making it even harder to obtain a blood sample. Gentle massaging of the finger or warming the hands may help with blood flow.
D. It is important to wash hands before testing to ensure that the blood sample is not contaminated with food residues, dirt, or other substances that could affect the accuracy of the glucose reading.
