Nursing Elites

1. 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.

2. 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.

3. A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:

• A. Should be taken in the morning
• B. May increase the client's energy level
• C. Does not need to be stored in a dark container
• D. May increase the client's heart rate

Correct answer: A

Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.

4. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?

• A. CK and Troponin
• B. BUN and Creatinine
• C. Amylase and Lipase
• D. HDL and LDL Cholesterol Levels

Correct answer: C

Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.

5. When auscultating the patient's lungs during a shift assessment on a patient admitted in the early phase of heart failure, which finding would the nurse most likely hear?

• A. Continuous rumbling, snoring, or rattling sounds mainly on expiration
• B. Continuous high-pitched musical sounds on inspiration and expiration
• C. Discontinuous, high-pitched sounds of short duration heard on inspiration
• D. A series of long-duration, discontinuous, low-pitched sounds during inspiration

Correct answer: C

Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.
