Nursing Elites

1. For which patient diagnosis would a prescription for nifedipine be least appropriate?

• A. Angina Pectoris
• B. Essential HTN
• C. Atrial Fibrillation
• D. Vasospastic Angina

Correct answer: C

Rationale: Nifedipine primarily acts as a calcium channel blocker, exerting its effects on vascular smooth muscle. It is not effective for treating dysrhythmias like Atrial Fibrillation, which involve abnormalities in the heart's electrical system. Nifedipine is commonly prescribed for conditions such as angina pectoris, essential hypertension, and vasospastic angina due to its vasodilatory and anti-anginal properties. Choices A, B, and D are more appropriate as nifedipine can help in managing angina pectoris, hypertension, and vasospastic angina by reducing myocardial oxygen demand and dilating coronary arteries.

2. A healthcare provider is preparing to administer ibuprofen 5 mg per kg every 6 hours PRN for temperatures above 38.0 degrees Celsius or 100.5 degrees Fahrenheit to an infant who weighs 17.6 lb. The infant has a temperature of 38.4 degrees Celsius or 101.2 degrees Fahrenheit. Available is ibuprofen liquid 100 mg/5 ml. How many milliliters should the healthcare provider administer to the infant?

• A. 12 ml
• B. 6 ml
• C. 2 ml
• D. 1 ml

Correct answer: C

Rationale: To calculate the correct dosage, first convert the infant's weight to kilograms: 17.6 lb = 8 kg. The prescribed dose is 5 mg/kg, so for an 8 kg infant, the total dose required is 40 mg. Since the available ibuprofen liquid is 100 mg/5 ml, to find out how many milliliters to administer, divide the total dose (40 mg) by the concentration of the liquid (100 mg/5 ml), which equals 2 ml. Therefore, the healthcare provider should administer 2 ml of ibuprofen to the infant.

3. The patient taking warfarin for prevention of deep vein thrombosis has an INR of 1.2. Which action by the nurse is most appropriate?

• A. Administer IV push protamine sulfate
• B. Continue with the current prescription.
• C. Prepare to administer Vitamin K
• D. Call healthcare provider to increase the dose

Correct answer: D

Rationale: An INR level of 1.2 is below the therapeutic range (2-3) for warfarin therapy. Therefore, the nurse should contact the healthcare provider to discuss the need for an increased dose to achieve the desired therapeutic range and prevent deep vein thrombosis effectively. Administering IV push protamine sulfate is used to reverse the effects of heparin, not warfarin. Continuing with the current prescription without addressing the subtherapeutic INR level may not effectively prevent deep vein thrombosis. Administering Vitamin K is indicated for warfarin overdose leading to excessive anticoagulation, not for a subtherapeutic INR level that is below the target range.

4. A parent of an infant with gastroesophageal reflux is being taught by a nurse. Which of the following instructions should the nurse include in the teaching?

• A. Offer the infant feedings every 2 hours.
• B. Position the infant upright after feedings.
• C. Feed the infant thickened formula.
• D. Place the infant in a prone position after feedings.

Correct answer: B

Rationale: Correct posture after feedings is crucial for an infant with gastroesophageal reflux to reduce the risk of regurgitation. Placing the infant upright helps prevent the backflow of stomach contents into the esophagus, minimizing symptoms of reflux.

5. What is the most appropriate nursing consideration for a patient who is prescribed verapamil and digoxin?

• A. Restrict intake of oral fluids and high-fiber foods
• B. Take an apical pulse for 30 seconds before administration
• C. Notify the healthcare provider of nausea, vomiting, and visual changes
• D. Hold the medications if the heart rate is greater than 110 bpm

Correct answer: C

Rationale: When a patient is prescribed verapamil and digoxin, it is crucial to monitor for signs of digoxin toxicity due to the potential interaction between these medications. Verapamil can elevate digoxin blood serum levels, increasing the risk of toxicity. Symptoms of digoxin toxicity include nausea, vomiting, and visual changes. Therefore, the most appropriate nursing consideration is to notify the healthcare provider of these symptoms. Restricting intake of oral fluids and high-fiber foods is not a specific consideration related to this medication combination. Before administering digoxin, it is essential to take an apical pulse for a full minute, not just 30 seconds, to ensure accuracy. Additionally, holding the medications if the heart rate exceeds 110 bpm is not a typical response to the combination of verapamil and digoxin, which can cause bradycardia rather than tachycardia.
