Nursing Elites

1. A healthcare provider is assessing a client who has severe dehydration. Which finding indicates effective treatment?

• A. Sunken anterior fontanel
• B. Tenting skin turgor
• C. Flat anterior fontanel
• D. Hyperpnea

Correct answer: C

Rationale: A flat anterior fontanel indicates effective treatment for dehydration in infants. Dehydration often causes sunken fontanels, so when the anterior fontanel becomes flat, it suggests that rehydration has occurred. Sunken anterior fontanel (Choice A) is a sign of dehydration, not effective treatment. Tenting skin turgor (Choice B) is also a sign of dehydration, indicating poor skin turgor. Hyperpnea (Choice D) is increased depth and rate of breathing and is not directly related to the hydration status of the client.

2. A healthcare provider is reviewing the laboratory data of a client with diabetes mellitus. Which of the following laboratory tests is an indicator of long-term disease management?

• A. Postprandial blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Glucose tolerance test
• D. Fasting blood glucose

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). The glycosylated hemoglobin test measures average blood glucose levels over the past 2-3 months, providing an indication of long-term glycemic control in clients with diabetes. Choice A, postprandial blood glucose, reflects blood sugar levels after a meal and does not provide a long-term view. Choice C, glucose tolerance test, evaluates the body's ability to process sugar but does not offer a continuous assessment like the HbA1c test. Choice D, fasting blood glucose, measures blood sugar levels after a period of fasting, which is more indicative of immediate glycemic status rather than long-term management.

3. A nurse is reviewing laboratory results for a client who has chronic kidney disease. Which of the following findings should the nurse expect?

• A. Hypernatremia
• B. Hypocalcemia
• C. Low potassium
• D. Low magnesium

Correct answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

4. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

5. A nurse is developing a plan of care for a newborn who has hyperbilirubinemia and a prescription for phototherapy. Which of the following interventions should the nurse include?

• A. Check the newborn's temperature every 4 hours
• B. Apply moisturizing lotion to the newborn's skin every 4 hours
• C. Give the newborn 1 oz of glucose water every 4 hours
• D. Reposition the newborn every 2 to 3 hours

Correct answer: D

Rationale: Repositioning the newborn every 2 to 3 hours during phototherapy is important to expose all areas of the skin to light and facilitate the breakdown of bilirubin. Checking the newborn's temperature is important, but it should be done more frequently, such as every 4 hours, to monitor for any signs of overheating or hypothermia. Applying moisturizing lotion is not indicated during phototherapy as it may interfere with the treatment. Giving glucose water is not necessary for the management of hyperbilirubinemia.
