1. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which intervention is most important?
- A. Administer insulin as prescribed.
- B. Monitor the client's urine output.
- C. Assess the client's level of consciousness.
- D. Obtain an arterial blood gas (ABG) sample.
Correct answer: A
Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.
2. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products. His current blood pressure is 78/52 mm Hg, and he is being mechanically ventilated. His oxygen saturation is 87%. Laboratory values indicate hemoglobin of 7 g/dL, platelets of 20,000/mm³, and white blood cells of 2,000/mm³. Which intervention should the nurse implement first?
- A. Transfuse packed red blood cells.
- B. Obtain blood and sputum cultures.
- C. Infuse 1000 ml of normal saline.
- D. Titrate oxygen to keep O2 saturation above 90%.
Correct answer: A
Rationale: The correct answer is to transfuse packed red blood cells first. The client's low hemoglobin level of 7 g/dL indicates severe anemia, which requires immediate transfusion to increase oxygen-carrying capacity. While obtaining blood and sputum cultures (Choice B) is important to identify potential infections, addressing the critical issue of anemia takes precedence. Infusing normal saline (Choice C) may help with volume status but does not address the primary concern of low hemoglobin. Titration of oxygen (Choice D) is crucial, but transfusion to improve oxygen-carrying capacity should be the priority in this scenario.
3. The nurse is assessing the thorax and lungs of a client who is experiencing respiratory difficulty. Which finding is most indicative of respiratory distress?
- A. Contractions of the sternocleidomastoid muscle.
- B. Respiratory rate of 20 breaths/min
- C. Downward movement of diaphragm with inspiration
- D. A pulse oximetry reading of SpO2 95%
Correct answer: A
Rationale: The correct answer is A: Contractions of the sternocleidomastoid muscle. Contractions of the sternocleidomastoid muscle suggest that the client is using accessory muscles to breathe, which is a clear sign of respiratory distress. This finding indicates that the client is working harder to breathe, typically seen in conditions like asthma, COPD, or respiratory failure. Choices B, C, and D are not the most indicative of respiratory distress. A respiratory rate of 20 breaths/min falls within the normal range. Downward movement of the diaphragm with inspiration is a normal finding indicating effective diaphragmatic breathing. A pulse oximetry reading of SpO2 95% is within the normal range and does not necessarily indicate respiratory distress.
4. A client with liver cirrhosis and ascites is admitted with jaundice. Which laboratory value is most concerning to the nurse?
- A. Serum albumin of 3.0 g/dl
- B. Bilirubin of 3.0 mg/dl
- C. Ammonia level of 80 mcg/dl
- D. Prothrombin time of 18 seconds
Correct answer: C
Rationale: An ammonia level of 80 mcg/dl is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to neurological symptoms such as confusion, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are important in liver cirrhosis but are not the most concerning for acute neurological deterioration associated with hepatic encephalopathy.
5. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?
- A. White blood cell count
- B. Liver function tests
- C. Kidney function tests
- D. Complete blood count
Correct answer: B
Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.
