Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. Select the criteria that is accurately paired with its indication of birth weight or gestational age.

• A. Low birth weight: The neonate's weight is less than 1,500 g at the time of delivery.
• B. Appropriate for gestational age: The neonate's weight ranges from the 10th to the 90th percentile.
• C. Large for gestational age: The neonate's weight is above the 99th percentile.
• D. Small for gestational age: The neonate's weight is below the 20th percentile.

Correct answer: B

Rationale: Appropriate for gestational age (AGA) indicates a neonate's weight ranging from the 10th to the 90th percentile. This range signifies that the baby's weight is within the normal range for their gestational age. Choices A, C, and D provide inaccurate information about the criteria and do not correctly correspond to the indicated birth weight or gestational age. Low birth weight typically refers to a weight below 2,500 g, large for gestational age above the 90th percentile, and small for gestational age below the 10th percentile.

3. Which of the following is a benefit of the U.S. health-care system?

• A. With cost savings from technology, more Americans now have health-care insurance.
• B. Quality of care has improved in the United States.
• C. Care in the United States has shifted to a prevention focus rather than an illness focus.
• D. The use of technology is projected to decrease health-care costs and improve clinical outcomes.

Correct answer: D

Rationale: The correct answer is D because the use of technology and electronic health records is projected to decrease health-care costs and improve clinical outcomes, quality, and safety. Choice A is incorrect because it states that very few Americans have no health-care insurance, which is not a benefit of the U.S. health-care system. Choice B may be true, but it does not directly address a benefit of the health-care system. Choice C is not necessarily a benefit but rather a shift in focus, so it is also incorrect.

4. Select the types of pain that are accurately coupled with an example of it. Select all that are correct.

• A. Radicular pain: Pain shooting down the leg from a herniated disc
• B. Central neuropathic pain: Pain from nerve damage after a stroke
• C. Peripheral neuropathic pain: Pain from diabetic neuropathy in the feet
• D. Chronic pain: Pain lasting for more than 3-6 months

Correct answer: D

Rationale: The correct answer is D because chronic pain is characterized by lasting for a prolonged period, typically more than 3-6 months, and is not necessarily related to acute injuries like a stab wound to the chest. Choices A, B, and C are incorrect because they do not accurately match the type of pain with its corresponding example. Radicular pain is pain that radiates along the nerve path, often from a pinched nerve or herniated disc, not a broken bone. Central neuropathic pain arises from damage to the central nervous system, such as after a stroke, not a leg injury. Peripheral neuropathic pain is caused by damage to the peripheral nerves, such as in diabetic neuropathy, not a fractured leg bone.

5. Select the stage of viral hepatitis that is accurately paired with its characteristic(s).

• A. The prodromal stage: Jaundice begins
• B. The icteric stage: Flu-like symptoms occur
• C. The pre-icteric stage: Elevated urine bilirubin levels
• D. The post-icteric stage: Jaundice and dark urine occur

Correct answer: D

Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.
