A patient asks the nurse for information about fat-soluble vitamins. What is the nurse's best response?

Correct Answer: C

Rationale: Fat-soluble vitamins (A, D, E, K) are stored in the liver and adipose tissue and excreted slowly, making them more likely to accumulate and cause toxicity if taken in excess. They are not metabolized rapidly (A) and can be stored in the liver (B). They can be toxic (D) if consumed in large amounts.

Correct Answer: B

Rationale: Carbonic anhydrase inhibitors are a class of medications used to treat edema by decreasing the production of aqueous humor in the eye and reducing fluid in the body. One common side effect of carbonic anhydrase inhibitors is metabolic acidosis, which can lead to increased blood glucose levels in patients with diabetes. The medication may interfere with the body's ability to regulate blood glucose levels, leading to elevated blood glucose. Therefore, when monitoring a patient with diabetes who is receiving a carbonic anhydrase inhibitor, the nurse should closely monitor for signs of elevated blood glucose levels to prevent potential complications.

Correct Answer: B

Rationale: Articaine is considered the most potent ester type of local anesthetic. It is known for its high efficacy in providing profound anesthesia due to its unique chemical structure that enhances its ability to penetrate tissues effectively. Articaine also has a rapid onset of action and a relatively long duration of action compared to other ester local anesthetics. These characteristics make it a popular choice for various dental and medical procedures where deep and long-lasting anesthesia is required.

Correct Answer: B

Rationale: Before administering Digoxin, the nurse should count the apical pulse for 1 minute. Digoxin is a cardiac medication that primarily works by increasing the force of contractions of the heart muscle. It is important to assess the patient's heart rate to ensure it is within the recommended range before administering Digoxin. This is because Digoxin can cause serious complications such as heart arrhythmias if given when the heart rate is too low. Counting the apical pulse for a full minute provides a more accurate assessment of the heart rate compared to shorter durations.

Correct Answer: C

Rationale: Fat-soluble vitamins (A, D, E, K) are stored in the liver and adipose tissue and excreted slowly, making them more likely to accumulate and cause toxicity if taken in excess. They are not metabolized rapidly (A) and can be stored in the liver (B). They can be toxic (D) if consumed in large amounts.
