Nursing Elites

1. The patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving epoprostenol (Flolan). Which assessment information requires the most immediate action by the nurse?

• A. The oxygen saturation is 94%.
• B. The blood pressure is 98/56 mm Hg.
• C. The patient's central IV line is disconnected.
• D. The international normalized ratio (INR) is prolonged.

Correct answer: C

Rationale: The most immediate action required by the nurse is to address the disconnected central IV line delivering epoprostenol (Flolan). Epoprostenol has a short half-life of 6 minutes, necessitating immediate reconnection to prevent rapid clinical deterioration. While oxygen saturation, blood pressure, and INR are important parameters requiring monitoring and intervention, the priority lies in ensuring the continuous delivery of the critical medication to stabilize the patient's condition.

2. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?

• A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
• B. "Strawberry tongue"? is a characteristic sign.
• C. Petechiae occur on the soft palate.
• D. The pharynx is red and swollen.

Correct answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

3. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

4. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.

5. A nurse caring for several patients in the cardiac unit is told that one is scheduled for implantation of an automatic internal cardioverter-defibrillator. Which of the following patients is most likely to have this procedure?

• A. A patient admitted for myocardial infarction without cardiac muscle damage.
• B. A postoperative coronary bypass patient, recovering on schedule.
• C. A patient with a history of ventricular tachycardia and syncopal episodes.
• D. A patient with a history of atrial tachycardia and fatigue.

Correct answer: C

Rationale: The correct answer is a patient with a history of ventricular tachycardia and syncopal episodes. An automatic internal cardioverter-defibrillator is used to deliver an electric shock to the heart to terminate episodes of ventricular tachycardia and ventricular fibrillation. These patients are at high risk of life-threatening arrhythmias, which may result in syncope. Patients with atrial tachycardia and fatigue (Choice D) would not typically require an implantable cardioverter-defibrillator as their primary issue is related to atrial arrhythmias. Patients who have had a myocardial infarction without cardiac muscle damage (Choice A) or postoperative coronary bypass patients recovering on schedule (Choice B) are not necessarily at high risk for ventricular arrhythmias and would not be the primary candidates for an implantable cardioverter-defibrillator.
