23. A nurse is preparing to administer potassium chloride 30 mEq PO daily. The amount available is potassium chloride 20 mEq/15mL. How many mL 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 ["22.5"]

To administer the correct dose of potassium chloride, which is 30 mEq, when the available solution is 20 mEq in 15 mL, the nurse needs to calculate the volume of the solution to provide the required mEq. The calculation is as follows: (30 mEq / 20 mEq) x 15 mL = 22.5 mL.

Correct Answer is B

Explanation

A. Atropine is not used as an antidote for warfarin overdose. It is primarily used to treat bradycardia and certain types of heart block.
B. Vitamin K is the antidote for warfarin overdose. Warfarin inhibits vitamin K-dependent clotting factors, and vitamin K helps reverse its effects by promoting clotting factor synthesis in the liver.
C. Protamine is used as an antidote for heparin, not warfarin. It binds to heparin to neutralize its anticoagulant effects.
D. Epinephrine is not used as an antidote for warfarin overdose. It is primarily used in emergencies such as severe allergic reactions (anaphylaxis) or cardiac arrest.

A. To ensure that that fluid and electrolyte balance is maintained B. To give the patient some much needed fluid intake C. To prevent interaction of medication with each other D. None of the above

Correct Answer is C

Explanation

Answer: C
A. Ensuring fluid and electrolyte balance is maintained is an important aspect of patient care but is not the primary reason for flushing the feeding tube between medications.
B. While giving the patient fluid intake is beneficial, the primary purpose of flushing the tube between medications is to prevent interactions between different medications.
C. Flushing the feeding tube with water between medication administrations helps prevent interactions between medications that may be incompatible, ensuring each medication is delivered effectively and safely.
D. This option is incorrect because flushing the tube between medications serves a specific purpose related to medication administration and safety.
