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 []

Explanation

Choice A reason:

There is no mention of an open wound that requires cleansing and dressing, so this action is not applicable based on the provided patient data.

Choice B reason:

The patient has blanchable redness on both heels and the coccyx, which are signs of pressure injury risk. Ofloading these areas is essential to prevent the development of pressure ulcers.

Choice C reason:

There is no indication of elder abuse in the provided scenario, so contacting adult protective services would not be appropriate.

Choice D reason:

Given the patient's difficulty with mobility and the reported occasional accidents, a bowel training program could help manage his bowel incontinence and improve his quality of life.

Choice E reason:

An enema is not indicated as there is no evidence of constipation or bowel obstruction in the patient's history or nurse's notes.

Condition F reason:

The patient is most likely experiencing pressure injuries, as indicated by the redness on his heels and coccyx, which are common sites for pressure ulcers due to immobility.

Condition G reason:

There is no evidence of elder abuse in the patient's history or nurse's notes. Condition H reason:

Altered nutrition may be a concern due to the patient's reported difficulty eating full meals and less than optimal intake, but it is not the primary condition indicated by the nurse's assessment.

Condition I reason:

There is no evidence of bowel obstruction; the patient's main issue seems to be related to pressure injury and incontinence.

Parameter J reason:

Monitoring wound status is crucial for managing and tracking the healing process of any existing or potential pressure injuries.

Parameter K reason:

While documentation of skin prevention measures is important, it is not as immediate as monitoring wound status and incontinence episodes.

Parameter L reason:

Monitoring incontinence episodes will help evaluate the effectiveness of the bowel training program and any other interventions put in place to manage the patient's incontinence.

Parameter M reason:

Vital signs should always be monitored, but they are not specific to assessing the progress of pressure injury management or bowel training program effectiveness.

Parameter N reason:

Family dynamics are not relevant in this case as the patient lives alone and there is no indication of family involvement in his care.

A. Serum potassium: 3.5 mEq/L (3.5 mmol/L), serum sodium: 142 mEq/L (142 mmol/L) B. Serum potassium: 4.5 mEq/L (4.5 mmol/L), serum sodium: 140 mEq/L (140 mmol/L) C. Serum potassium: 5.0 mEq/L (5.0 mmol/L), serum sodium: 138 mEq/L (138 mmol/L) D. Serum potassium: 3.0 mEq/L (3.0 mmol/L), serum sodium: 149 mEq/L (149 mmol/L)

Correct Answer is A

Explanation

Choice A reason: The results are within the normal reference range for both potassium and sodium, which is expected unless the client's condition has led to significant electrolyte imbalances.

Choice B reason: A serum potassium level of 4.5 mEq/L is at the higher end of the normal range, which might not be expected in a client with vomiting and diarrhea, conditions that often lead to lower potassium levels.

Choice C reason: A serum potassium level of 5.0 mEq/L is at the upper limit of the normal range and could indicate hyperkalemia, especially in the context of severe dehydration.

Choice D reason: A serum sodium level of 149 mEq/L is slightly above the normal range and could indicate hypernatremia, which may occur in dehydration but would require further assessment and intervention.
