The nurse discovers that an older client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

Genetically inherited disorders of family members.

Frequency of laxative use for chronic constipation.

Length and frequency of the client's tobacco use.

Ingestion of shellfish or fish oil capsules daily.

Answer and Explanation

The Correct Answer is B

A) Incorrect- Genetically inherited disorders of family members: While a family history of certain disorders might provide some insight, it is not typically the primary cause of elevated serum magnesium levels in an older adult.
B) Correct- Elevated serum magnesium levels are commonly associated with chronic laxative use, especially those containing magnesium-based compounds. Laxatives can lead to excessive magnesium intake, causing hypermagnesemia.
C. Incorrect- Smoking is not a common cause of elevated serum magnesium levels.

D. Incorrect- While dietary sources can contribute to magnesium intake, chronic laxative use is a more likely cause in this context.

Correct Answer is ["1.3"]

Explanation

1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg

= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.

2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL
