1. What is the likely cause of pericarditis in a young patient?

• A. Heart failure
• B. Acute MI
• C. Hypertension
• D. Infectious processes

Correct answer: D

Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.

2. 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.

3. Which laboratory test result should the nurse monitor to evaluate the effects of therapy for a 62-year-old female patient with acute pancreatitis?

• A. Calcium
• B. Bilirubin
• C. Amylase
• D. Potassium

Correct answer: C

Rationale: The correct answer is C: Amylase. In acute pancreatitis, amylase levels are typically elevated. Monitoring amylase levels helps assess the effectiveness of therapy in managing the condition. Elevated amylase is a key indicator of pancreatic inflammation. Calcium (Choice A) levels may be affected in pancreatitis, but they are not the primary indicator for evaluating therapy effectiveness. Bilirubin (Choice B) and Potassium (Choice D) levels may also be altered in pancreatitis, but they are not specific markers for monitoring therapy response in acute pancreatitis.

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. A 7-year-old child is seen in a clinic, and the pediatrician documents a diagnosis of nighttime (nocturnal) enuresis. What information should the nurse provide to the parents?

• A. Nighttime (nocturnal) enuresis does not respond to treatment.
• B. Nighttime (nocturnal) enuresis is caused by a psychiatric problem.
• C. Nighttime (nocturnal) enuresis requires surgical intervention to improve the problem.
• D. Nighttime (nocturnal) enuresis is usually outgrown without therapeutic intervention.

Correct answer: D

Rationale: Nighttime (nocturnal) enuresis is common in children and is characterized by a child who has never been dry at night for extended periods. Most children eventually outgrow bedwetting without therapeutic intervention. This condition is due to the child being unable to sense a full bladder and not awakening to void, often related to delayed maturation of the central nervous system. It is important for parents to understand that nighttime (nocturnal) enuresis is not caused by a psychiatric problem, does not typically require surgical intervention, and usually resolves on its own over time.
