Nursing Elites

1. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?

• A. Heparin
• B. Alprazolam
• C. Digoxin
• D. Levothyroxine

Correct answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

2. A healthcare provider is reviewing the health history of a client who has a prescription for Propranolol. Which of the following findings should the provider report?

• A. Previous history of thromboembolism
• B. Concurrent use of an antacid
• C. History of bronchial asthma
• D. Recent weight gain

Correct answer: C

Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with a history of bronchial asthma. Reporting a history of bronchial asthma to the provider is crucial as it would prompt a review of the medication prescription to avoid potential adverse effects and consider alternative treatment options.

3. A nurse is evaluating teaching for a client who has Rheumatoid Arthritis and a new prescription for Methotrexate. Which of the following statements by the client indicates understanding of the teaching?

• A. I will be sure to return to the clinic at least once a year to have my blood drawn while I'm taking methotrexate.
• B. I will take this medication on an empty stomach.
• C. I'll let the doctor know if I develop sores in my mouth while taking this medication.
• D. I should stop taking oral contraceptives while I'm taking methotrexate.

Correct answer: C

Rationale: Ulcerations in the mouth, tongue, or throat are often the first signs of methotrexate toxicity and should be reported to the provider immediately.

4. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?

• A. 4 mL
• B. 5 mL
• C. 6 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.

5. A client is starting a course of Metronidazole to treat an infection. For which of the following adverse effects should the client stop taking Metronidazole and notify the provider?

• A. Metallic taste
• B. Nausea
• C. Ataxia
• D. Dark-colored urine

Correct answer: C

Rationale: The correct answer is C, 'Ataxia.' Ataxia is a sign of central nervous system (CNS) toxicity, which can be a severe adverse effect of Metronidazole. Metallic taste and nausea are common side effects of Metronidazole but do not require stopping the medication unless they persist or worsen. Dark-colored urine is not typically associated with Metronidazole and does not indicate a severe adverse effect.
