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

Choice A reason: While heart rate is important, it is not the most immediate concern when a client shows signs of cyanosis.

Choice B reason: Blood pressure is a critical vital sign but does not directly address the issue of oxygenation, which is suggested by cyanosis.

Choice C reason: Temperature is less relevant to the immediate assessment of cyanosis, which is often related to oxygenation issues.

Choice D reason: Respiratory rate should be assessed first as cyanosis is a sign of potential hypoxia, and the respiratory rate can provide immediate information about the client's breathing and oxygenation status.

A. Orient the client to their surroundings. B. Close the client's room door. C. Escort the client back to the room. D. Raise the four side rails on the bed. E. Secure a bed alarm on the mattress.

Correct Answer is ["A","C","E"]

Explanation

Choice A reason: Orienting the client to their surroundings is essential for a confused patient. It can help reduce anxiety and prevent further confusion. It is a non-invasive, immediate intervention that can provide comfort and safety to the patient.

Choice B reason: Closing the client's room door is not recommended as it may increase the patient's feeling of isolation and can be a safety issue if the patient needs immediate assistance.

Choice C reason: Escorting the client back to the room is a correct action. It ensures the safety of the client by preventing falls or wandering, which could lead to harm.

Choice D reason: Raising all four side rails on the bed can be considered a form of restraint and is not recommended. It can increase the risk of injury if the client attempts to climb over the rails and can contribute to feelings of confusion and agitation.

Choice E reason: Securing a bed alarm on the mattress is a correct action. It alerts the staff if the client attempts to leave the bed, allowing for quick intervention to ensure the client's safety.
