Nursing Elites

1. At what age does a 9-year-old child typically lose which of the following teeth?

• A. Central incisor
• B. Second molar
• C. Lateral incisor
• D. Cuspid

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

2. Which electrolyte imbalance is most likely to cause cardiac arrhythmias?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.

3. A client with peripheral neuropathy due to cirrhosis is at risk for injury. What should the nurse do?

• A. Protect the client's feet from injury
• B. Apply a heating pad to the affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct answer: A

Rationale: Protecting the client's feet from injury is critical as peripheral neuropathy can lead to decreased sensation and increased risk of trauma. This measure helps prevent wounds, ulcers, and other complications. Applying a heating pad (Choice B) can worsen symptoms and cause burns due to decreased sensation. Keeping the client's feet elevated (Choice C) may help reduce swelling but does not directly address the risk of injury. Assessing for jaundice (Choice D) is important in cirrhosis but is not directly related to the client's risk of injury due to peripheral neuropathy.

4. A client who is at full-term gestation is in active labor and complains of a cramp in her leg. Which intervention should the PN implement?

• A. Massage the calf and foot
• B. Elevate the leg above the heart
• C. Check the pedal pulse in the affected leg
• D. Extend the leg and flex the foot

Correct answer: D

Rationale: During labor, muscle cramps are common due to prolonged muscle tension. The correct intervention to alleviate a cramp in the leg is to extend the leg and flex the foot. This action helps relieve the muscle spasm by stretching and contracting the muscles. Massaging the calf and foot (Choice A) may not be as effective in relieving the cramp as extending and flexing the leg. Elevating the leg above the heart (Choice B) is not necessary and may not directly address the cramp. Checking the pedal pulse (Choice C) is important for assessing circulation, but it does not directly address the muscle cramp.

5. A male client who has been diagnosed with schizophrenia is withdrawn, isolates himself in the day room, and answers questions with one or two-word responses. This morning, the practical nurse observes that he is diaphoretic and is pacing in the hall. Which intervention is most important for the PN to implement?

• A. Persuade the client to lie down
• B. Provide a drink high in electrolytes
• C. Observe the client during the shift
• D. Measure appropriate vital signs

Correct answer: D

Rationale: Measuring vital signs is crucial in this situation as it helps to determine if the client is experiencing a physical health issue or if the symptoms are related to a mental health crisis, such as anxiety or agitation. The presence of diaphoresis and pacing may indicate physiological changes requiring immediate attention. Providing a drink high in electrolytes or persuading the client to lie down may not address the underlying cause of the symptoms. Simply observing the client during the shift without taking necessary actions to assess his physiological status may delay appropriate intervention.
