Nursing Elites

1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. When educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia, which instruction should the nurse include?

• A. Take this medication in the morning.
• B. Avoid drinking grapefruit juice.
• C. Increase your intake of green, leafy vegetables.
• D. Expect your stools to turn clay-colored.

Correct answer: B

Rationale: The correct instruction for the nurse to include when educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia is to avoid drinking grapefruit juice. Grapefruit juice can increase the blood levels of atorvastatin, leading to an elevated risk of serious side effects such as liver damage and muscle problems. It is essential for the client to be aware of this potential interaction and to follow the nurse's advice to avoid grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect. Taking Atorvastatin in the morning is a common recommendation but not the priority over avoiding grapefruit juice. Increasing intake of green, leafy vegetables is generally a healthy dietary choice but is not specific to the medication. Expecting stools to turn clay-colored is not a common side effect of Atorvastatin.

3. A client is taking Spironolactone. Which of the following laboratory findings should the nurse monitor and report to the provider?

• A. Sodium level of 138 mEq/L
• B. Potassium level of 5.2 mEq/L
• C. Chloride level of 100 mEq/L
• D. Calcium level of 9.5 mg/dL

Correct answer: B

Rationale: The correct answer is B: Potassium level of 5.2 mEq/L. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia (elevated potassium levels). A potassium level of 5.2 mEq/L is considered elevated and should be reported to the provider for further assessment and management to prevent potential complications. Choices A, C, and D are not directly affected by Spironolactone and do not typically require immediate reporting unless there are other underlying issues or specific instructions for those electrolytes.

4. A toddler is being admitted to the hospital after an Acetaminophen overdose. Which of the following medications should the nurse anticipate administering to this patient?

• A. Acetylcysteine
• B. Pegfilgrastim
• C. Misoprostol
• D. Naltrexone

Correct answer: A

Rationale: In cases of Acetaminophen overdose, acetylcysteine is the antidote of choice. Acetylcysteine helps prevent liver damage by replenishing depleted glutathione levels, which is essential for detoxifying acetaminophen metabolites. Pegfilgrastim is a medication used to stimulate white blood cell production, Misoprostol is a medication for preventing stomach ulcers, and Naltrexone is used for treating opioid addiction and alcoholism, but none of these are indicated for Acetaminophen overdose.

5. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.
