1. A client had an inferior wall myocardial infarction (MI). The nurse notes the client's cardiac rhythm as shown below. What action by the nurse is most important?
- A. Assess the client's blood pressure and level of consciousness.
- B. Call the health care provider or the Rapid Response Team.
- C. Obtain a permit for an emergency temporary pacemaker insertion.
- D. Prepare to administer antidysrhythmic medication.
Correct answer: A
Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.
2. A client tests positive for alpha1-antitrypsin (AAT) deficiency and asks the nurse, What does this mean? How should the nurse respond?
- A. Your children may be at high risk for developing chronic obstructive pulmonary disease.
- B. I will arrange for a genetic counselor to discuss your condition.
- C. Your risk for chronic obstructive pulmonary disease is higher, particularly if you smoke.
- D. This is a recessive gene that should not affect your health.
Correct answer: C
Rationale: Alpha1-antitrypsin (AAT) deficiency is associated with a higher risk of chronic obstructive pulmonary disease (COPD), especially if the individual smokes. This condition is caused by a recessive gene. Individuals with one allele typically produce enough AAT to prevent COPD unless they smoke. However, those with two alleles are at high risk for COPD even without exposure to smoke or other irritants. Being a carrier of AAT deficiency does not guarantee that one's children will develop the disease; it depends on the AAT levels of the partner. While involving a genetic counselor may be beneficial in the long run, the immediate concern of the client's question should be addressed first.
3. A client has a new diagnosis of myasthenia gravis. For which of the following manifestations should the nurse monitor?
- A. Confusion
- B. Weakness
- C. Increased intracranial pressure
- D. Increased urinary output
Correct answer: B
Rationale: In myasthenia gravis, a neuromuscular disorder characterized by muscle weakness and fatigue, weakness is a common manifestation due to the immune system attacking the communication between nerves and muscles. Monitoring for weakness is crucial to assess the disease progression and determine the effectiveness of treatment. Confusion is not a typical manifestation of myasthenia gravis. Increased intracranial pressure and increased urinary output are not directly associated with this condition.
4. A healthcare provider assesses a client with pneumonia. Which clinical manifestation should the provider expect to find?
- A. Fremitus
- B. Hyperresonance
- C. Dullness on percussion
- D. Decreased tactile fremitus
Correct answer: C
Rationale: Pneumonia often leads to the consolidation of lung tissue, resulting in dullness on percussion. This occurs due to the presence of fluid or inflammatory material in the alveoli. Fremitus and decreased tactile fremitus are more indicative of conditions like pleural effusion or pneumothorax, where there is an increase in the density of the pleural space or air in the pleural cavity. Hyperresonance, on the other hand, is typically associated with conditions causing air trapping, such as emphysema, where there is increased air in the alveoli.
5. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: C
Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.
