Nursing Elites

1. A client with a history of atrial fibrillation is taking digoxin (Lanoxin). Which finding should the healthcare provider be notified of immediately?

• A. Heart rate of 52 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Blood glucose level of 180 mg/dL
• D. Potassium level of 4.0 mEq/L

Correct answer: A

Rationale: A heart rate of 52 beats per minute is a critical finding in a client taking digoxin, as it may indicate digoxin toxicity. Digoxin can cause bradycardia as a side effect, and a heart rate of 52 bpm warrants immediate attention to prevent adverse outcomes. Monitoring and reporting changes in heart rate are crucial in clients on digoxin therapy to prevent serious complications. The other vital signs and laboratory values provided are within normal ranges or not directly associated with digoxin toxicity in this scenario, making them lower priority for immediate reporting.

2. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing techniques?

• A. The nurse washes with her hands held higher than her elbows.
• B. The nurse uses a brush to scrub under her nails.
• C. The nurse washes for at least 30 seconds.
• D. The nurse uses alcohol-based hand rub only.

Correct answer: A

Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.

3. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?

• A. Muscle weakness
• B. Joint pain
• C. Vision changes
• D. Skin rash

Correct answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).

4. The nurse is caring for a client who was successfully resuscitated from a pulseless dysrhythmia. Which of the following assessments is MOST critical for the nurse to include in the plan of care?

• A. Hourly urine output
• B. White blood cell count
• C. Blood glucose every 4 hours
• D. Temperature every 2 hours

Correct answer: A

Rationale: Monitoring hourly urine output is crucial after successful resuscitation from a pulseless dysrhythmia to assess kidney function and perfusion. The kidneys are particularly vulnerable to injury following cardiac events due to decreased perfusion during the event. Evaluating urine output hourly allows for early detection of renal impairment or inadequate organ perfusion. Option B, monitoring white blood cell count, is not a priority in this situation as it does not directly relate to immediate post-resuscitation care. Option C, checking blood glucose every 4 hours, is important but not as critical as assessing kidney function and perfusion. Option D, measuring temperature every 2 hours, is relevant for monitoring signs of infection or inflammatory response but is not as crucial as assessing kidney function in this scenario.

5. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to

• A. Stabilize alveolar surface tension
• B. Maintain alveolar surface tension
• C. Promote normal pulmonary blood flow
• D. Regulate intra-cardiac pressure

Correct answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.
