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

The correct answer is choiced. Proceed with teaching the client how to walk with the crutches.

Choice A rationale:

Confer with the physical therapist for correct crutch size. This is unnecessary because the crutches are already correctly fitted.A space of three finger widths between the top of the crutch and the client’s axilla is appropriate to prevent pressure on the axilla and potential nerve damage.

Choice B rationale:

Ask the client to sit down while the crutch length is adjusted. This action is not needed since the crutches are already properly adjusted.Adjusting the crutch length further could lead to improper fitting, which might cause discomfort or injury.

Choice C rationale:

Assess the client for signs of diminished circulation in the hands. While assessing circulation is important, it is not directly related to the fitting of the crutches.Proper crutch fitting focuses on ensuring there is no pressure on the axilla and that the client can use the crutches comfortably.

Choice D rationale:

Proceed with teaching the client how to walk with the crutches. This is the correct action because the crutches are already properly fitted.The nurse should now focus on educating the client on the correct use of the crutches to ensure safe and effective mobility.

A. Complete an admission assessment. B. Access a central venous line. C. Reinforce discharge teaching. D. Initiate blood product infusions.

Correct Answer is C

Explanation

Choice A reason: Completing an admission assessment is typically the responsibility of a registered nurse (RN) due to the comprehensive nature of the assessment.

Choice B reason: Accessing a central venous line is usually within the scope of practice of an RN, not a PN, due to the complexity and potential complications associated with central lines.

Choice C reason: Reinforcing discharge teaching is an appropriate task for a PN, as it involves reviewing and ensuring the client understands the instructions already provided by the RN or healthcare provider.

Choice D reason: Initiating blood product infusions is generally the responsibility of an RN because of the critical nature of the task and the potential for adverse reactions.
