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
This is because the first priority for assessing an elderly client who has become confused since admission is to rule out hypoxia, which can cause or worsen delirium. Hypoxia can result from various conditions, such as pneumonia, pulmonary embolism, or heart failure.
Oxygen saturation measurement is a quick and non-invasive way to assess the oxygen level in the blood and identify hypoxia.
Choice B. Review of current medications is wrong because although medications can cause or contribute to confusion and delirium in older adults, they are not the most urgent assessment to perform.
Medications should be reviewed after ensuring adequate oxygenation and addressing other possible causes of confusion.
Choice C. Intake and output last 24 hours is wrong because although dehydration and electrolyte imbalance can cause or worsen confusion and delirium in older adults, they are not the most urgent assessment to perform.
Intake and output should be monitored after ensuring adequate oxygenation and addressing other possible causes of confusion.
Choice D. Use of hearing aids or glasses is wrong because although sensory impairment can cause or worsen confusion and delirium in older adults, it is not the most urgent assessment to perform.
The use of hearing aids or glasses should be ensured after ensuring adequate oxygenation and addressing other possible causes of confusion.
Normal ranges for oxygen saturation are 95% to 100% for healthy adults. Lower levels may indicate hypoxia or other respiratory or cardiac problems.
Correct Answer is B
Explanation
The nurse should hold and notify the prescriber because hydrochlorothiazide is a diuretic that can lower the serum potassium level. The client already has a high serum potassium level of 5.2 mmol/L, which is above the normal range of 3.5 to 5.0 mmol/L.
Giving hydrochlorothiazide could worsen the client’s condition and cause hypokalemia.
Choice A is wrong because metoprolol is a beta-blocker that can lower the blood pressure and heart rate.
The client’s blood pressure and heart rate are not given, so there is no reason to hold metoprolol based on the information provided.
Choice C is wrong because enoxaparin is an anticoagulant that can prevent blood clots. The client has a low platelet count of 98,000/mm, which is below the normal range of 150,000 to 450,000/mm.
However, this does not contraindicate the use of enoxaparin, unless the client has signs of bleeding or bruising.
Choice D is wrong because atorvastatin is a statin that can lower the serum cholesterol
level. The client has a high serum cholesterol level of 250 mg/dL, which is above the desirable level of less than 200 mg/dL.
Giving atorvastatin could help reduce the client’s risk of cardiovascular complications.
