The healthcare provider prescribes magnesium hydroxide 4,800 mg PO at bedtime for a patient with constipation. The bottle is labeled, "Magnesium Hydroxide Saline Laxative, USP 400 mg per 5 mL". How many ounces should the nurse instruct the patient to take with each dose? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["2"]

The healthcare provider has prescribed 4,800 mg of magnesium hydroxide. The bottle indicates that each 5 mL contains 400 mg of magnesium hydroxide. We also know that 1 ounce (oz) is equivalent to 30 mL.

Step 1: The amount of magnesium hydroxide the patient needs is 4,800 mg.

Step 2: The concentration of the magnesium hydroxide solution is 400 mg per 5 mL. Step 3: Substitute the values into the formula: 4,800 mg ÷ (400 mg/5 mL).

Step 4: Calculate the volume in mL: 4,800 ÷ (400/5) = 60 mL.

Now, we need to convert this volume from mL to ounces.

Step 5: We know that 1 oz = 30 mL.

Step 6: Substitute the values into the formula: 60 mL ÷ 30 mL/oz.

Step 7: Calculate the volume in oz: 60 ÷ 30 = 2 oz.

Correct Answer is D

Explanation

Choice A reason: Dizziness is not typically associated with perineal care and is not relevant to the instructions.

Choice B reason: Advising to keep the pubic area shaved is not a standard part of perineal care instructions and is a personal choice.

Choice C reason: The statement about not retracting the foreskin is incorrect; the foreskin should be retracted gently for cleaning and then returned to its normal position to prevent infection.

Choice D reason: It is important to inform the caregiver that an erection may occur as a natural reflex during perineal care, and it does not indicate any sexual intent. This helps prepare the caregiver to handle the situation professionally.

A. Review the client's medical history and admission assessment. B. Compare the client's current vital signs to the admission baseline. C. Note how frequently doses of analgesics have been administered. D. Ask the client to describe the intensity of the pain being experienced.

Correct Answer is D

Explanation

Choice A reason: While the client's medical history and admission assessment provide valuable information, they do not directly measure the current pain experience.

Choice B reason: Vital signs can indicate pain but are not a definitive measure of pain severity as they can be influenced by other factors.

Choice C reason: The frequency of analgesic administration may suggest the level of pain control but does not measure the current pain intensity experienced by the client.

Choice D reason: Asking the client to describe the intensity of the pain is the most direct and effective way to assess pain severity. Pain is subjective, and the client's self-report is considered the gold standard for pain assessment.
