18. A nurse is preparing to administer levothyroxine 100 mcg PO to a client who has hypothyroidism. Available is levothyroxine 50 mcg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To administer the correct dose of levothyroxine, which is 100 mcg, the nurse would need to give two tablets of the 50 mcg levothyroxine. This is because two tablets of 50 mcg each will sum up to the total prescribed dose of 100 mcg.

Correct Answer is A

Explanation

A. Guaifenesin works as an expectorant by stimulating and thinning respiratory tract secretions, making it easier for the client to cough up and clear mucus from the airways.
B. Suppressing the urge to cough is the action of antitussive medications, not expectorants like guaifenesin.
C. Guaifenesin does not have significant anti-inflammatory properties; its primary action is on mucus clearance.
D. Drying mucous membranes is not the mechanism of action for guaifenesin; it focuses on facilitating mucus removal.

A. Administer the crushed medication through the NG tube. B. Administer the medication under the client's tongue. C. Request a prescription for an oral formulation of the medication. D. Dissolve the medication in water and give it through the NG tube.

Correct Answer is B

Explanation

A. Sublingual medications are meant to be absorbed under the tongue and should not be administered through an NG tube, which bypasses this route of absorption.
B. Administering the medication under the tongue is the correct route for sublingual administration. It ensures that the medication is allowed to dissolve completely and is not swallowed immediately. This allows for the intended rapid absorption through the sublingual route.
C. If a client has an NG tube and needs a medication that is typically given sublingually, the nurse should administer the medication under the tongue.
D. Dissolving sublingual medication in water for NG tube administration is not appropriate as it alters the intended route of absorption.
