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 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.
Correct Answer is A
Explanation
A client who grimaces during a dressing change is showing a nonverbal sign of pain. Grimacing is an expression of facial muscles that indicates discomfort or distress.
The nurse should record this as a symptom of pain and ask the client to rate the pain using a numeric or visual scale.
Choice B is wrong because an elevated heart rate while exercising is not necessarily a symptom of pain. It could be a normal response to increased physical activity or a sign of other conditions such as anxiety, dehydration, or fever.
Choice C is wrong because crying during a procedure is not a reliable indicator of pain. Crying is an emotional response that can be influenced by many factors such as fear, stress, or sadness.
The nurse should not assume that the client is in pain based on crying alone and should ask the client about the reason for crying and the level of pain.
Choice D is wrong because saying “I feel achy all over” is not a specific description of pain.
Aching is a vague term that can refer to different sensations such as soreness, stiffness, or cramping.
The nurse should ask the client to clarify what kind of pain they are feeling, where it is located, how severe it is, and what makes it better or worse.
