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. Confirm that bowel sounds are present. B. Measure the client's total body weight. C. Evaluate the client's ability to swallow. D. Observe for signs of fluid volume deficit.

Correct Answer is A

Explanation

Choice A reason: Before initiating tube feeding, it is crucial to ensure that the gastrointestinal system is functioning. The presence of bowel sounds indicates peristalsis, which is necessary for the digestion and absorption of the feeding.

Choice B reason: While measuring the client's total body weight is important for overall assessment and monitoring of nutritional status, it is not the most critical assessment before starting tube feeding.

Choice C reason: Evaluating the client's ability to swallow is not relevant in this scenario since the client will be receiving nutrition through a feeding tube due to malnutrition and dehydration.

Choice D reason: Observing for signs of fluid volume deficit is important, but the immediate concern before starting tube feeding is to confirm gastrointestinal activity through the presence of bowel sounds.
