Nursing Elites

1. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. A client has a new prescription for Atenolol. Which of the following instructions should the nurse provide?

• A. Take this medication with grapefruit juice.
• B. Monitor your blood pressure and heart rate regularly.
• C. You may experience a rapid heart rate.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Monitor your blood pressure and heart rate regularly.' Atenolol is a beta-blocker used to treat hypertension and other cardiovascular conditions. Patients should monitor their blood pressure and heart rate regularly to assess the medication's effectiveness and check for adverse effects like bradycardia or hypotension. Choice A is incorrect because Atenolol should not be taken with grapefruit juice, which can interfere with its absorption. Choice C is incorrect because Atenolol typically causes a decrease in heart rate, not a rapid heart rate. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Atenolol.

3. A client is being assessed by a healthcare provider while taking Digoxin to manage heart failure. Which of the following findings is a manifestation of digoxin toxicity?

• A. Bruising
• B. Report of metallic taste
• C. Muscle pain
• D. Report of anorexia

Correct answer: D

Rationale: The correct manifestation of digoxin toxicity is anorexia, not bruising, metallic taste, or muscle pain. Other symptoms of digoxin toxicity include blurred vision, stomach pain, and diarrhea. It is crucial for healthcare providers to promptly identify these signs to prevent severe complications.

4. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?

• A. Discontinue the medication if a rash develops.
• B. Expect increased salivation during the first few weeks of therapy.
• C. Avoid driving until the client's reaction to the medication is known.
• D. Stop the medication if you experience a dry mouth.

Correct answer: C

Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so engaging in activities like driving that require alertness should be avoided until the individual understands how the medication affects them. Choices A, B, and D are incorrect because they do not address the specific side effect of drowsiness associated with clonidine that could impair driving abilities. Discontinuing the medication if a rash develops, expecting increased salivation, or stopping the medication for dry mouth are not primary concerns related to clonidine therapy for hypertension.

5. A client has a new prescription for Propranolol. Which of the following findings should the healthcare provider identify as a contraindication to this medication?

• A. Asthma
• B. Diabetes mellitus
• C. Hypertension
• D. Glaucoma

Correct answer: A

Rationale: Propranolol is a non-selective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with asthma. Asthma is a contraindication for Propranolol due to the potential of worsening bronchoconstriction and causing respiratory distress in individuals with this condition. Diabetes mellitus, hypertension, and glaucoma are not contraindications for Propranolol.
