A patient calls the clinic office saying that the cholestyramine (Questran) powder he started yesterday clumps and sticks to the glass when he tries to mix it. The nurse will suggest what method for mixing this medication for administration?

Correct Answer: C

Rationale: The nurse should suggest the patient mix the cholestyramine powder with food or fruit, or at least 4 to 6 ounces of fluid. Cholestyramine is a medication that works by binding with bile acids in the intestine, which requires mixing the powder with a sufficient amount of fluid to ensure proper administration. Mixing the powder with 4 to 6 ounces of fluid or food will help prevent clumping and ensure optimal effectiveness of the medication. Mixing it with a carbonated soda drink (option A) may not be ideal as the effervescence could affect the medication's stability. Adding the powder to any liquid and stirring vigorously (option B) may not effectively dissolve the powder. Taking the powder dry followed by a glass of water (option E) may also not be as effective in ensuring proper administration as when mixed with food or fluid.

Correct Answer: B

Rationale: The antidote for Heparin, which is an anticoagulant medication, is protamine sulfate. Heparin works by inhibiting the body's ability to form blood clots, and an overdose of Heparin can lead to excessive bleeding. Protamine sulfate works by neutralizing the anticoagulant effects of Heparin. This antidote is particularly useful in cases of overdose or when immediate reversal of Heparin's effects is needed, such as during surgery or in emergency situations. Other options listed, such as Warfarin, Insulin, and Naloxone, are not the appropriate antidotes for Heparin toxicity.

Correct Answer: A

Rationale: Regular insulin is the only type of insulin that can be given intravenously (IV) due to its short onset of action. When administered IV, regular insulin can act quickly to control blood sugar levels in emergency situations such as diabetic ketoacidosis (DKA) or hyperglycemic crises. Other types of insulin, such as NPH, long-acting, or rapid-acting insulins, are not suitable for IV administration as they have different pharmacokinetic properties and are designed for subcutaneous use.

Correct Answer: A

Rationale: The therapeutic use of Digoxin is primarily to increase cardiac output and slow down the heart rate. Digoxin is a cardiac glycoside that works by increasing the force of the heart's contractions, thereby improving cardiac output in conditions such as heart failure. Additionally, it also helps to slow down the heart rate by affecting the electrical conduction system of the heart. This combination of effects makes Digoxin valuable in treating conditions like heart failure, atrial fibrillation, and atrial flutter.
