Double the dose if a dose is missed.

Reduce caffeine and acidic intake.

Avoid taking on an empty stomach.

Consume 2. liters of water daily.

Answer and Explanation

The Correct Answer is A

A. Double the dose if a dose is missed:
This instruction is incorrect. Clients should not double their dose of allopurinol if they miss a dose. Instead, they should take the missed dose as soon as they remember, unless it is almost time for the next dose. Doubling the dose can lead to overdose and potential side effects.

B. Reduce caffeine and acidic intake:
Reducing caffeine and acidic foods can help manage gout and lower uric acid levels, making this advice appropriate.

C. Avoid taking on an empty stomach:
While allopurinol can be taken with or without food, some clients might find it less irritating if taken with food. This guidance is intended to reduce gastrointestinal discomfort.

D. Consume 2 liters of water daily:
Drinking adequate fluids helps prevent kidney stones and promotes overall kidney health, which is especially important when taking allopurinol. This advice supports effective medication use and overall health.

Correct Answer is B

Explanation

A. Monitor the client's serum electrolytes:
Amlodipine, a calcium channel blocker, primarily affects blood pressure and not directly electrolyte levels. Monitoring electrolytes is more relevant for medications that affect electrolyte balance, such as diuretics or certain antihypertensives.

B. Measure the client's blood pressure:
Amlodipine is used to treat hypertension and angina by relaxing blood vessels. The primary measure of its effectiveness is the reduction in blood pressure. Therefore, measuring the client’s blood pressure is crucial to assess whether the medication is effectively managing hypertension.

C. Review the client's intake and output:
While monitoring intake and output is important for assessing fluid balance and kidney function, it is not the primary method for evaluating the effectiveness of amlodipine in controlling blood pressure.

D. Note the client's serum calcium levels:
Amlodipine affects calcium channels but does not directly influence serum calcium levels significantly. Serum calcium levels are not used to assess the effectiveness of amlodipine in treating hypertension or angina.

Correct Answer is ["37.5"]

Explanation

Convert grams to milligrams: 4 grams = 4000 mg

Determine the concentration of magnesium sulfate in the solution: 4000 mg / 500 mL = 8 mg/mL

Calculate the volume needed to deliver 300 mg/hour:

300 mg/hour ÷ 8 mg/mL = 37.5 mL/hour

Therefore, the nurse should set the infusion pump to deliver 37.5 mL/hour.
