The nurse is reviewing the medication list with a client with hypothyroidism who is prescribed levothyroxine (Synthroid). The nurse should notify the health care provider if the client reported taking which of the following medications?
magnesium hydroxide (Milk of Magnesia)
amitriptyline (Elavil)
acetaminophen (Tylenol)
gabapentin (Neurontin)
The Correct Answer is A
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.

Correct Answer is ["0.5"]
Explanation
First, determine how many milligrams are in 1 mL. We can do this by dividing the total milligrams by the total milliliters: 24 mg ÷ 2 mL = 12 mg/mL
Now we know that each milliliter of the solution contains 12 mg of sumatriptan.
To find the volume needed for a 6 mg dose, we need to figure out how many times 12 mg goes into 6 mg: 6 mg ÷ 12 mg/mL = 0.5 mL
Correct Answer is B
Explanation
A. Typically, in hyperglycemia (high blood sugar), sodium may be retained, not decreased, due to the osmotic effect of glucose. Increased urine output can lead to some sodium loss, but it is not the primary concern here.
B. When blood glucose levels exceed the renal threshold (around 180 mg/dL), the kidneys cannot reabsorb all the glucose, and it spills over into the urine. This leads to glucosuria (glucose in urine), which is common in uncontrolled diabetes.
C. Hyperglycemia can initially cause increased potassium levels in the blood due to shifts between intracellular and extracellular compartments. However, increased urination (polyuria) can eventually lead to potassium loss, not decreased potassium in urine.
D. Ketones in the urine (ketonuria) are more commonly seen in type 1 diabetes or in cases of diabetic ketoacidosis (DKA), which is often associated with severe insulin deficiency and fat breakdown. While it's possible to see ketones in type 2 diabetes, this is not typically the first finding with a blood sugar level of 289 mg/dL.
