1. An elderly client is admitted with a diagnosis of bacterial pneumonia. The nurse's assessment of the client will most likely reveal which sign/symptom?
- A. Leukocytosis and febrile.
- B. Polycythemia and crackles.
- C. Pharyngitis and sputum production.
- D. Confusion and tachycardia.
Correct answer: D
Rationale: The onset of pneumonia in the elderly may be signaled by general deterioration, confusion, increased heart rate or increased respiratory rate due to the decreased oxygen- carbon dioxide exchange at the alveoli, known as the V-Q mismatch.
2. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: B
Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.
3. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: C
Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.
4. A nurse is suctioning a client through a tracheostomy tube. During the procedure, the client begins to cough, and the nurse hears a wheeze. The nurse tries to remove the suction catheter from the client’s trachea but is unable to do so. What should the nurse do first?
- A. Call a code
- B. Contact the physician
- C. Administer a bronchodilator
- D. Disconnect the suction source from the catheter
Correct answer: D
Rationale: Inability to remove a suction catheter is a critical situation that may indicate the presence of bronchospasm and bronchoconstriction, as evidenced by the client coughing and wheezing. The immediate action for the nurse is to disconnect the suction source from the catheter, allowing the catheter to remain in the trachea. By doing so, the nurse can then connect the oxygen source to the catheter to provide essential oxygenation to the client. Contacting the physician is necessary to notify them of the situation and to obtain further orders, typically for an inhaled bronchodilator to relieve the bronchospasm. Administering a bronchodilator without physician's orders is not within the nurse's scope of practice and should not be the first action. Calling a code would be excessive at this point and should only be done if the client's condition deteriorates and immediate resuscitation is required.
5. What is the most common cause of coronary artery disease?
- A. Atherosclerosis.
- B. Hyperlipidemia.
- C. Diabetes.
- D. Smoking.
Correct answer: A
Rationale: The correct answer is Atherosclerosis. It is the primary cause of coronary artery disease, as it involves the buildup of plaque in the arteries, restricting blood flow to the heart. Hyperlipidemia (choice B) contributes to atherosclerosis by increasing cholesterol levels in the blood but is not the direct cause of coronary artery disease. Diabetes (choice C) can accelerate atherosclerosis due to high blood sugar levels, but it is not the most common cause. Smoking (choice D) is a significant risk factor for developing coronary artery disease but is not the primary cause.
