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.)
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 C
Explanation
Choice A reason: Offering to contact the family's spiritual counselor can provide emotional and spiritual support, but it is not the immediate priority in a situation where the client has expressed a desire to have life support withdrawn.
Choice B reason: Discussing comfort measures is important for the client and family to understand what to expect during the withdrawal process. However, this step comes after the healthcare provider has been informed and a plan of care is being developed.
Choice C reason: Informing the healthcare provider is the priority nursing intervention. The nurse acts as an advocate for the client's wishes and ensures that the appropriate steps are taken to respect the client's autonomy and decisions regarding their care.
Choice D reason: Explaining the actions that the healthcare team will follow is an essential part of the process, but it is not the first step. The healthcare provider must first be informed so that the proper orders and arrangements can be made.

Choice C reason: Obtaining current client data is essential to compare with the expected outcomes and determine if the goals of care are being met.
