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 B

Explanation

Choice A reason: While unpleasant odor can indicate poor oral hygiene or other health issues, it is not as urgent as some other findings.

Choice B reason: White patches on the mucosa can indicate an infection such as oral thrush, which requires medical treatment, making it the most important finding to act upon.

Choice C reason: A receding gumline is a concern for dental health but does not typically require immediate action.

Choice D reason: Discoloration of teeth can indicate various issues, including dietary habits or decay, but is not as immediately concerning as white patches on the mucosa. Bolded text indicates the correct answers and important information.

A. Provide at least 20 minutes of back massage and gentle efleurage. B. Instruct the client to use guided imagery and slow rhythmic breathing. C. Place a hot water circulation device, such as an aquathermia pad, on the operative site. D. Tune to a television show or easy listening music to provide distraction.

Correct Answer is A

Explanation

Choice A reason: Providing a back massage and gentle efleurage can help alleviate pain through relaxation
techniques and is a non-pharmacological method to manage pain.

Choice B reason: Guided imagery and slow rhythmic breathing are helpful relaxation techniques, but they may not be as immediately effective for incisional pain as direct physical interventions.

Choice C reason: The use of a hot water circulation device should be done with caution postoperatively, as it may not be appropriate depending on the surgical site and the client's condition.

Choice D reason: Distraction techniques like watching television or listening to music can be helpful, but they may not address the physical component of the client's incisional pain.
