1. What is the antidote for Warfarin?

• A. Naloxone
• B. Vitamin K
• C. Glucagon
• D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

2. A healthcare provider is assessing a client who is taking levothyroxine. The healthcare provider should recognize that which of the following findings is a manifestation of levothyroxine overdose?

• A. Insomnia
• B. Constipation
• C. Drowsiness
• D. Hypoactive deep-tendon reflexes

Correct answer: A

Rationale: Insomnia is a common symptom of levothyroxine overdose due to excessive stimulation of the central nervous system. Levothyroxine is a thyroid hormone replacement medication, and an overdose can lead to hyperthyroidism symptoms, including insomnia. Constipation and drowsiness are not typically associated with levothyroxine overdose. Hypoactive deep-tendon reflexes are more indicative of hypothyroidism rather than an overdose of levothyroxine.

3. A healthcare professional reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the professional take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication, and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments. Choice B is incorrect because waiting 24 hours after taking the medication would not provide an accurate trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect because obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level, as it is the lowest concentration before the next dose.

4. When teaching a client how to use nitroglycerin transdermal ointment for angina, which instruction should the nurse include?

• A. Remove the prior dose before applying a new dose.
• B. Rub the ointment directly into your skin until it is no longer visible.
• C. Cover the applied ointment with a clean gauze pad.
• D. Apply the ointment to the same skin area each time.

Correct answer: A

Rationale: The correct instruction is to remove the prior dose before applying a new dose. This helps prevent toxicity by ensuring the client does not inadvertently apply an excessive amount of nitroglycerin.

5. A client asks the nurse to explain the difference between stable and unstable angina. What is the best response by the nurse?

• A. "Stable angina is predictable in its frequency, intensity, and duration. Unstable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• B. "Unstable angina is caused by spasms of the coronary arteries. Stable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• C. "Unstable angina is predictable in its frequency, intensity, and duration. Stable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• D. "Stable angina is caused by spasms of the coronary arteries. Unstable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?

Correct answer: A

Rationale: Stable angina is typically triggered by physical exertion or emotional stress and is predictable in its frequency, intensity, and duration. In contrast, unstable angina is characterized by angina episodes that are unexpected, more severe, prolonged, and can occur at rest. Understanding these differences can help healthcare providers assess and manage angina episodes effectively, ensuring appropriate interventions are implemented promptly based on the type of angina present.
