A health care provider prescribes guaifenesin with dextromethorphan 1 tablespoon every 6 hours for a client who has a nonproductive cough.
How many milliliters should a nurse administer for each dose?
10 mL.
5 mL.
15 ml.
30 ml.
The Correct Answer is D
This is because the prescribed dose is 1 tablespoon, which is equivalent to 15 ml. Therefore, to get the amount of milliliters for each dose, you need to multiply 15 ml by 2, which gives you 30 ml.
Choice A is wrong because 10 ml is less than 1 tablespoon.
Choice B is wrong because 5 ml is equal to 1 teaspoon, which is one-third of a tablespoon.
Choice C is wrong because 15 ml is equal to 1 tablespoon, which is half of the prescribed dose.

Correct Answer is A
Explanation
“Since I am taking Clozaril, I will need to have bloodwork performed weekly for six months.” This indicates that the client understands that Clozaril (clozapine) is an antipsychotic medication that can affect the immune system and cause a serious blood disorder called agranulocytosis. The client needs to have regular blood tests to monitor the white blood cell count and prevent infections.
Choice B is wrong because Clozaril can cause urinary retention, not decreased urination. The client should be advised to report any difficulty or pain when urinating.
Choice C is wrong because Clozaril is not a PRN medication. It should be taken regularly as prescribed by the doctor to maintain a therapeutic level and prevent relapse of psychotic symptoms.
Choice D is wrong because Clozaril is not available over the counter or in a generic form. It is a controlled substance that requires a special program and a certified pharmacy to dispense it.
Correct Answer is C
Explanation
This is because furosemide is a diuretic that makes you pee more and lose water and electrolytes such as potassium and sodium.
Therefore, you should avoid foods that are high in sodium or potassium, such as bananas, oranges, cranberries, and bagels with cream cheese.
You should also drink plenty of fluids to prevent dehydration.
Choice A is wrong because oatmeal with a banana, milk, and orange juice contains too much potassium, which can cause irregular heartbeat or muscle weakness when taking furosemide.
Choice B is wrong because blueberry muffins, cranberry juice, and herbal tea contain too much sodium and sugar, which can raise your blood pressure and worsen your heart failure.
Choice D is wrong because a bagel with low-fat cream cheese and decaffeinated coffee contains too much sodium and caffeine, which can cause fluid retention and increase your heart rate.
Normal ranges for potassium are 3.5 to 5.0 mmol/L and for sodium are 135 to 145 mmol/L.
You should monitor your electrolyte levels regularly when taking furosemide.
