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.)

Answer and Explanation

The Correct Answer is ["7.5"]

To calculate the amount of potassium chloride elixir needed per dose, we can use the following formula:

Amount per dose (mL) = (Desired dose in mEq / Concentration in mEq/mL) * Volume in mL

Given:

Desired dose = 20 mEq/day divided equally every 12 hr = 10 mEq/dose

Concentration = 6.7 mEq/5 mL

Plugging in the values:

Amount per dose (mL) = (10 mEq / 6.7 mEq/5 mL) * 5 mL

Calculating:

Amount per dose (mL) ≈ 7.46 mL

Rounded to the nearest tenth, the nurse should administer approximately 7.5 mL of the potassium chloride elixir per dose.

Correct Answer is A

Explanation

A. Estrogen-progestin combination:
Correct Answer: This medication interacts with carbamazepine.
Explanation: Carbamazepine is known to induce certain liver enzymes, including cytochrome P450 enzymes. These enzymes play a role in the metabolism of various medications, including estrogen-containing oral contraceptives (estrogen-progestin combinations). Carbamazepine can increase the metabolism of estrogen-progestin combinations, potentially reducing their effectiveness and increasing the risk of contraceptive failure. Therefore, this interaction can lead to decreased contraceptive efficacy and the potential for unintended pregnancy.
B. Nicotine transdermal system:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Nicotine replacement therapies, such as nicotine transdermal systems, are not known to have significant interactions with carbamazepine. These therapies are primarily used to aid in smoking cessation and do not share metabolic pathways with carbamazepine.
C. Diphenhydramine:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Diphenhydramine is an antihistamine used for allergies and as a sleep aid. It does not have a well-established interaction with carbamazepine. However, it's important to note that carbamazepine can have central nervous system (CNS) effects, so caution should be exercised when combining it with other medications that also have CNS effects.
D. Beclomethasone:
Incorrect Explanation: This medication does not interact with carbamazepine.
Explanation: Beclomethasone is a corticosteroid used to manage inflammation associated with conditions like asthma and allergic rhinitis. It is not known to interact with carbamazepine. These two medications have different mechanisms of action and do not share significant metabolic pathways.

A. Morphine 6 mg IV push every 3 hr PRN acute pain B. Morphine 6.0 mg IV push every 3 hr PRN acute pain C. MS 6 mg IV push every 3 hr PRN acute pain D. MSO4 6 mg IV push every 3 hr PRN acute pain

Correct Answer is A

Explanation

A. Morphine 6 mg IV push every 3 hr PRN acute pain:
This choice is correct. It accurately transcribes the medication name (morphine), the dosage (6 mg), the route (IV push), the frequency (every 3 hours), and the indication (PRN for acute pain).
B. Morphine 6.0 mg IV push every 3 hr PRN acute pain:
This choice is not incorrect, but it is unnecessary to include the trailing zero in the dosage (6.0 mg). Both "6" and "6.0" indicate the same value, and omitting the decimal point is common practice in medication dosages.
C. MS 6 mg IV push every 3 hr PRN acute pain:
This choice is incorrect. "MS" is an abbreviation for "morphine sulfate," but it's not widely used in modern healthcare settings. Using the full name "morphine" is clearer and less prone to confusion.
D. MSO4 6 mg IV push every 3 hr PRN acute pain:
This choice is incorrect. "MSO4" is the chemical symbol for morphine sulfate. While it's a valid abbreviation, it's not as commonly used as the full name "morphine." Using the full name of the medication is clearer and more familiar to healthcare professionals.
