Nursing Elites

1. A client with myasthenia gravis is receiving pyridostigmine (Mestinon). The nurse should monitor the client for which of the following side effects?

• A. Constipation
• B. Hypertension
• C. Muscle weakness
• D. Bradycardia

Correct answer: D

Rationale: The correct answer is D: Bradycardia. Pyridostigmine, a cholinesterase inhibitor used in myasthenia gravis, can lead to bradycardia as a side effect. Choice A, constipation, is not a common side effect of pyridostigmine. Choice B, hypertension, is unlikely as pyridostigmine is more likely to cause hypotension. Choice C, muscle weakness, is actually a symptom of myasthenia gravis itself and not a side effect of pyridostigmine.

2. After accepting the position of school nurse in a public elementary school, what strategy is best for the nurse to use to obtain an overview understanding of the student body?

• A. Review all health records of the students currently enrolled in classes.
• B. Talk with the current members of the parent-teacher association.
• C. Send a survey form to parents of third-grade students.
• D. Conduct a windshield survey of the geographic areas served by the school.

Correct answer: D

Rationale: Conducting a windshield survey is the best strategy for the nurse to obtain an overview understanding of the student body. This method allows the nurse to observe the community, its resources, potential health hazards, and demographic information. Reviewing health records (Choice A) would provide detailed health information but not an overview of the student body. Talking with the parent-teacher association (Choice B) may offer insights but not a comprehensive overview. Sending a survey form to parents (Choice C) may provide specific information but may not capture a broad understanding of the student body.

3. A 4-month-old child taking digoxin (Lanoxin) has a blood pressure of 92/78; resting pulse of 78; respirations 28, and a potassium level of 4.8 mEq/L. The client is irritable and has vomited twice since the morning dose of digoxin. Which finding is most indicative of digoxin toxicity?

• A. Bradycardia
• B. Lethargy
• C. Irritability
• D. Vomiting

Correct answer: A

Rationale: Bradycardia (abnormally slow heart rate) is a key sign of digoxin toxicity. In this scenario, the child's symptoms of irritability, vomiting, along with the resting pulse of 78 despite being on digoxin, suggest an impending bradycardia due to digoxin toxicity. Lethargy can also be a sign, but in this case, the child is irritable rather than lethargic. Vomiting, though a symptom, is not as specific to digoxin toxicity as bradycardia. Irritability, while present, is not the most indicative finding of digoxin toxicity compared to bradycardia.

4. The nurse is caring for a client on mechanical ventilation. When performing endotracheal suctioning, the nurse will avoid hypoxia by

• A. Inserting a fenestrated catheter with a whistle tip without suction
• B. Completing the suction pass in 30 seconds with a pressure of 150 mm Hg
• C. Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass
• D. Minimizing the suction pass to 60 seconds while slowly rotating the lubricated catheter

Correct answer: C

Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.

5. When a nurse from the surgical department is reassigned to the pediatric unit, the charge nurse should recognize that the child at highest risk for cardiac arrest and is the least likely to be assigned to this nurse is which child?

• A. Congenital cardiac defects
• B. An acute febrile illness
• C. Prolonged hypoxemia
• D. Severe multiple trauma

Correct answer: C

Rationale: The correct answer is C, 'Prolonged hypoxemia.' Prolonged hypoxemia is a critical condition that requires specialized pediatric care due to the high risk of cardiac arrest. The other choices, such as congenital cardiac defects, acute febrile illness, and severe multiple trauma, may also require attention, but prolonged hypoxemia poses the highest risk for cardiac arrest and demands specialized expertise in managing pediatric patients with this condition.
