1. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?

A. Naloxone
B. Vitamin K
C. Digibind
D. Flumazenil

Correct answer: C

Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.

2. Which of the following is commonly used to treat migraine headaches?

A. Beta-blockers
B. Cholinesterase Inhibitors
C. ACE inhibitors
D. Anti-epileptic drugs (AEDs)

Correct answer: D

Rationale: Anti-epileptic drugs (AEDs) are often used in the management of migraine headaches due to their ability to help prevent or reduce the frequency and intensity of migraines. They work by stabilizing electrical activity in the brain, which can help in controlling migraine symptoms. While beta-blockers are also sometimes used in migraine prevention, anti-epileptic drugs are more commonly associated with migraine treatment. Cholinesterase Inhibitors are not typically used for migraine headaches, as they are more commonly associated with conditions like Alzheimer's disease. ACE inhibitors are a type of medication used to treat conditions like high blood pressure and heart failure, but they are not a first-line treatment for migraines.

3. What is an expected outcome for Lithium use in patients with bipolar disorder?

A. Reduced risk of myocardial infarction
B. Reduced risk of GI ulcers
C. Decrease in respiratory distress
D. Decreased incidence of acute manic episodes

Correct answer: D

Rationale: The correct answer is D: Decreased incidence of acute manic episodes. Lithium is commonly used to treat bipolar disorder by helping to stabilize mood and reduce the intensity and frequency of manic episodes. This leads to better overall management of the disorder. Choices A, B, and C are incorrect because lithium is not known to reduce the risk of myocardial infarction, GI ulcers, or respiratory distress in patients with bipolar disorder.

4. When administering Phenytoin, what should you monitor?

A. Behavior
B. Therapeutic blood levels
C. For signs of Stevens-Johnson syndrome
D. All of the above

Correct answer: D

Rationale: When administering Phenytoin, monitoring the patient's behavior is important to assess for any changes that may indicate adverse effects. Monitoring therapeutic blood levels helps ensure the medication is within the effective range and not causing toxicity. Additionally, being vigilant for signs of Stevens-Johnson syndrome, a severe skin reaction associated with Phenytoin use, is crucial for early detection and intervention. Therefore, monitoring behavior, therapeutic blood levels, and for signs of Stevens-Johnson syndrome are all essential when administering Phenytoin.

5. A client with HIV is starting therapy with zidovudine. The nurse should monitor the client for which of the following adverse effects of this medication?

A. Fatigue
B. Blurred vision
C. Ringing in the ears
D. Constipation

Correct answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to cause bone marrow suppression, resulting in decreased production of red blood cells and subsequent fatigue.
