1. A client is diagnosed with an acute myocardial infarction and is receiving tissue plasminogen activator, alteplase (Activase, tPA). Which action is a priority nursing intervention?
- A. Monitor for renal failure.
- B. Monitor psychosocial status.
- C. Monitor for signs of bleeding.
- D. Have heparin sodium available.
Correct answer: C
Rationale: The priority nursing intervention for a client receiving tissue plasminogen activator (alteplase) for an acute myocardial infarction is to monitor for signs of bleeding. Alteplase is a thrombolytic medication that can lead to hemorrhage as a complication. Therefore, closely monitoring the client for any signs of bleeding is essential to promptly address and manage this potential adverse effect.
2. Which of the following do prokaryotic cells lack?
- A. A cell membrane
- B. Genetic material
- C. Cytoplasm
- D. Membrane-bound organelles
Correct answer: D
Rationale: The correct answer is D: Prokaryotic cells lack membrane-bound organelles, such as mitochondria or a nucleus, distinguishing them from eukaryotic cells. Prokaryotic cells do have genetic material, a cell membrane, and cytoplasm. Choice A is incorrect because prokaryotic cells do have a cell membrane, which is essential for maintaining cell structure and regulating what enters and exits the cell. Choice B is incorrect because prokaryotic cells contain genetic material, typically in the form of a single circular chromosome. Choice C is incorrect because prokaryotic cells have cytoplasm, where various cellular activities take place.
3. A client is receiving external beam radiation to the mediastinum for treatment of bronchial cancer. Which of the following should take priority in planning care?
- A. Esophagitis
- B. Leukopenia
- C. Fatigue
- D. Skin irritation
Correct answer: B
Rationale: The correct answer is B: Leukopenia. Leukopenia, or a low white blood cell count, is a critical concern in clients undergoing radiation therapy due to the increased risk of infection. While esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, leukopenia poses a higher risk as it compromises the body's ability to fight infections effectively.
4. The nurse obtains a pulse rate of 89 beats/min for an infant before administering digoxin (Lanoxin). What action should the nurse take?
- A. Administer the medication.
- B. Hold the medication and contact the healthcare provider.
- C. Double the dose.
- D. Increase fluid intake.
Correct answer: B
Rationale: The correct answer is to hold the medication and contact the healthcare provider. Bradycardia (pulse rate less than 100 beats/minute) is an early sign of digoxin toxicity. It is essential to withhold digoxin and notify the healthcare provider to prevent potential adverse effects. Administering the medication (Choice A) could exacerbate the toxicity. Doubling the dose (Choice C) is inappropriate and dangerous. Increasing fluid intake (Choice D) is not indicated in this situation and does not address the issue of digoxin toxicity.
5. What is the priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula?
- A. Body temperature.
- B. Level of pain.
- C. Time of first void.
- D. Number of vessels in the cord.
Correct answer: D
Rationale: The priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula is to check the number of vessels in the cord. This assessment is crucial to identify any potential anomalies related to the TE fistula, as abnormalities in the cord vessels may indicate associated congenital anomalies that need immediate attention.
