A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
The correct answer is 7.5 ML
To answer this question, we need to use the formula:
mL to administer = (mEq ordered / mEq available) x mL available Plugging in the values from the question, we get:
mL to administer = (20 mEq/day / 6.7 mEq/5 mL) x 5 mL Simplifying, we get:
mL to administer = (2.99 mL/mEq) x 5 mL Multiplying, we get:
mL to administer = 14.95 mL/day
Since the order is to divide the dose equally every 12 hours, we need to divide the total daily dose by 2:
mL to administer per dose = 14.95 mL/day / 2 Dividing, we get:
mL to administer per dose = 7.475 mL
Rounding to the nearest tenth, we get:
mL to administer per dose = 7.5 mL
Therefore, the nurse should administer 7.5 mL of potassium chloride elixir per dose.

Correct Answer is A
Explanation
Choice A rationale:
Nicotine nasal spray delivers a rapid dose of nicotine to the bloodstream, which can help reduce cravings and withdrawal symptoms. The recommended dose is 1 to 2 sprays in each nostril every hour, up to 40 sprays per day. The client should not sniff, swallow, or inhale while spraying, and should avoid contact with the eyes and skin.
Choice B rationale:
The nicotine patch should be changed every 24 hours, not every other day. The patch provides a steady dose of nicotine through the skin, which can help prevent cravings and withdrawal symptoms. The client should apply the patch to a clean, dry, and hairless area of the skin, and rotate the site of application daily.
Choice C rationale:
the nicotine gum should be chewed for about 30 minutes, not 10 minutes, before spitting it out. The gum releases nicotine into the mouth, which is then absorbed into the bloodstream through the mucous membranes. The client should chew the gum slowly until a peppery taste or tingling sensation occurs, then park it between the cheek and gum until the taste or sensation fades, then repeat the process.
Choice D rationale:
The client should avoid drinking beverages for 15 minutes before and during sucking on a nicotine lozenge, not just while sucking on it. The lozenge dissolves in the mouth and releases nicotine, which is then absorbed into the bloodstream through the mucous membranes. Drinking beverages can interfere with the absorption of nicotine and reduce the effectiveness of the lozenge.
