1. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Taking four medications decreases the risk of a severe allergic reaction.
• B. Taking four medications reduces the chance that the bacteria will become resistant.
• C. Taking four medications reduces the risk of adverse reactions.
• D. Taking four medications decreases the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: When treating tuberculosis, using a combination of multiple medications is crucial to reduce the risk of bacterial resistance. The use of four medications helps to target the bacteria from different angles, making it harder for them to develop resistance to the treatment. This approach is essential to ensure the effectiveness of the treatment regimen and to prevent the spread of drug-resistant strains of tuberculosis. Choices A, C, and D are incorrect because the primary reason for using multiple medications in tuberculosis treatment is to prevent the development of bacterial resistance, not to decrease the risk of allergic reactions, adverse reactions, or affecting the tuberculin skin test results.

2. Which of the following is the antidote for Heparin toxicity?

• A. Protamine
• B. Methylene blue
• C. N-acetylcysteine
• D. Glucagon

Correct answer: A

Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.

3. Why has an ACE inhibitor been prescribed following an MI?

• A. “This medication will lower your potassium level.”
• B. “ACE inhibitors have been found to reduce mortality following MI.”
• C. “ACE inhibitors are always prescribed with a beta blocker and calcium channel blocker following an MI.”
• D. “This medication will treat your hypotension.”

Correct answer: B

Rationale: Following a myocardial infarction (MI), ACE inhibitors are commonly prescribed due to their proven benefit in reducing mortality and improving outcomes post-MI. These medications help by decreasing the workload of the heart, preventing remodeling of the heart chambers, and improving survival rates. While ACE inhibitors may have effects on potassium levels, the primary reason for their prescription post-MI is their mortality-reducing properties.

4. When teaching a client with a new prescription for Amiodarone, which instruction should the nurse include?

• A. Take this medication with meals.
• B. Avoid drinking grapefruit juice.
• C. Take this medication at bedtime.
• D. Increase your intake of sodium-rich foods.

Correct answer: B

Rationale: The correct instruction is to avoid drinking grapefruit juice when taking Amiodarone. Grapefruit juice can inhibit the metabolism of Amiodarone, leading to increased blood levels of the drug and potentially causing adverse effects like cardiac toxicity. Choices A, C, and D are incorrect because taking Amiodarone with meals, at bedtime, or increasing sodium-rich foods intake are not relevant instructions for this medication.

5. A client has a new prescription for Clonidine to assist with maintenance of abstinence from opioids. The nurse should instruct the client to monitor for which of the following adverse effects?

• A. Diarrhea
• B. Dry mouth
• C. Insomnia
• D. Hypertension

Correct answer: B

Rationale: Dry mouth is a common adverse effect associated with clonidine use. Clonidine is known to cause xerostomia (dry mouth) due to its effect on reducing salivary flow. Monitoring for dry mouth is important as it can lead to oral health issues and discomfort for the client. Diarrhea, insomnia, and hypertension are not typically associated with clonidine use, making them less likely adverse effects to monitor for in this scenario.
