Nursing Elites

1. When administering a shot of Vitamin K to a 30-day-old infant, which of the following target areas is the most appropriate?

• A. Gluteus maximus
• B. Gluteus minimus
• C. Vastus lateralis
• D. Vastus medialis

Correct answer: C

Rationale: When administering medications to infants, it is common to use the vastus lateralis muscle in the thigh for injections. The preferred site is the junction of the upper and middle thirds of the vastus lateralis muscle. This area provides a good muscle mass for the injection and minimizes the risk of hitting nerves or blood vessels. The gluteus maximus and gluteus minimus are not typically used for infant injections due to the risk of injury to the sciatic nerve. The vastus medialis is not as commonly used as the vastus lateralis for infant injections.

2. The patient is being taught about pulmonary function testing (PFT). Which statement made by the patient indicates effective teaching?

• A. I will use my inhaler right before the test.
• B. I won't eat or drink anything 8 hours before the test.
• C. I should inhale deeply and blow out as hard as I can during the test.
• D. My blood pressure and pulse will be checked every 15 minutes after the test.

Correct answer: C

Rationale: The correct answer is 'I should inhale deeply and blow out as hard as I can during the test.' This statement indicates effective teaching because for PFT, the patient needs to inhale deeply and exhale forcefully. This maneuver helps in assessing lung function accurately. Choices A, B, and D are incorrect. Using an inhaler right before the test may alter the test results, which is not recommended. Fasting for 8 hours is not necessary for a PFT, and checking blood pressure and pulse every 15 minutes after the test is not part of the PFT procedure.

3. 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.

4. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

5. The nurse is caring for a patient who has recently had a successful catheter ablation. Which assessment finding demonstrates a successful outcome of this procedure?

• A. The patient is free of electrolyte imbalances
• B. The patient's WBC count is within normal limits
• C. The patient's EKG reading is regular
• D. The patient's urine output is 45 mL/hour

Correct answer: C

Rationale: A successful outcome of a catheter ablation procedure for arrhythmias, particularly SVT, is indicated by a regular EKG reading. Catheter ablation involves the use of radiofrequency energy to destroy the conduction fiber in the heart responsible for the arrhythmia. This destruction helps in preventing further episodes of arrhythmia. While choices A, B, and D are important assessments in patient care, they are not specific indicators of the success of a catheter ablation procedure. Electrolyte imbalances, WBC count, and urine output can be affected by various factors and are not directly related to the effectiveness of a catheter ablation in treating arrhythmias.
