A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.4"]

To answer this question, we need to use the formula for calculating the dosage of medication:

Dose ordered / Dose on hand = Amount to administer

The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.

Correct Answer is B

Explanation

Choice A rationale:

Lithium carbonate should be taken with meals to minimize gastrointestinal upset.

Choice B rationale:

Lithium levels can be affected by sodium intake, so decreasing sodium intake can help prevent lithium toxicity.

Choice C rationale:

Tyramine is not typically restricted in clients taking lithium.

Choice D rationale:

Swelling of the feet is not a common adverse effect of lithium carbonate.

A. BUN 16 mg/dL B. Potassium 5.3 mEq/L C. Sodium 142 mEq/L D. Albumin 4 g/Dl

Correct Answer is B

Explanation

Choice A rationale:

BUN (blood urea nitrogen) measures kidney function and hydration status but is not a specific indicator for withholding triamterene.

Choice B rationale:

Triamterene is a potassium-sparing diuretic. With a potassium level of 5.3 mEq/L, which is elevated, the nurse should withhold the medication to prevent further potassium retention.

Choice C rationale:

Sodium level of 142 mEq/L is within the normal range and does not indicate a need to withhold triamterene.

Choice D rationale:

Albumin level of 4 g/dL is within the normal range and does not directly impact the decision to withhold triamterene.
