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 C
Explanation
The popliteal artery is a major blood vessel that runs behind the knee and supplies blood to the lower leg. Sitting with knees crossed can compress this artery and reduce blood flow to the leg.
This can cause numbness, tingling, or pain in the leg. It can also increase the risk of blood clots or varicose veins.
Choice A is wrong because sitting with knees crossed does not decrease the risk of skin breakdown behind the knee. In fact, it may increase the risk by causing friction or pressure on the skin.
Choice B is wrong because sitting with knees crossed does not eliminate the pain of arthritis in the lower legs.
Arthritis is a joint inflammation that causes pain, stiffness, and swelling. Sitting with knees crossed can worsen these symptoms by putting more stress on the knee joints.
Choice D is wrong because sitting with knees crossed does not avoid irritation of the knee joints.
On the contrary, it can cause irritation by overstretching the knee ligaments and muscles
Correct Answer is B
Explanation
Select a 0.5 mL syringe, 30 gauge, 8 mm needle and inject at a 90-degree angle. This is because Humulin R is a clear and colorless solution that can be given by subcutaneous injection.
A 0.5 mL syringe can hold up to 50 units of insulin, which is enough for the prescribed dose of 7 units. A 30 gauge, 8 mm needle is suitable for thin patients with poor skin turgor. Injecting at a 90-degree angle ensures that the insulin reaches the subcutaneous tissue and not the muscle.
Choice A is wrong because a 31 gauge, 6 mm needle is too short and may not deliver the insulin into the subcutaneous tissue.
Choice C is wrong because pinching the skin is not necessary for thin patients with poor skin turgor.
Choice D is wrong because a 1.0 mL syringe is too large for the prescribed dose of 7 units and may cause dosing errors. A 28 gauge, 12.7 mm needle is too long and may inject the insulin into the muscle, which can affect its absorption and action.
