Nursing Elites

1. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?

• A. Phenytoin level
• B. Sodium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

2. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

3. A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?

• A. Administer insulin as prescribed
• B. Provide a carbohydrate-controlled snack
• C. Encourage physical activity
• D. Recheck the blood sugar

Correct answer: A

Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.

4. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?

• A. Neurological integrity
• B. Renal functioning
• C. Thermoregulation
• D. Respiratory adequacy

Correct answer: A

Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.

5. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

• A. It helps reduce the production of intestinal gases.
• B. It ensures clearer imaging by emptying the stomach.
• C. It prevents the risk of aspiration during the procedure.
• D. It is a standard procedure for all surgical interventions.

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.
