Nursing Elites

1. 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.

2. A home health nurse is providing teaching to a patient who has a new diagnosis of a gastric ulcer and a new prescription for sucralfate oral suspension. What statement by the patient indicates an understanding of the teaching?

• A. I will take this medicine with meals.
• B. I will take this medicine right before bed.
• C. I will take this medicine 1 hour before meals and at bedtime.
• D. I will take this medicine only when I have symptoms.

Correct answer: C

Rationale: The correct answer is C because sucralfate should be taken on an empty stomach, 1 hour before meals, and at bedtime to coat the ulcer and protect it from stomach acid. Choice A is incorrect because taking it with meals may reduce its effectiveness. Choice B is incorrect as it should not be taken right before bed. Choice D is incorrect as sucralfate should be taken regularly as prescribed, not just when symptoms occur.

3. A nurse is planning discharge teaching for cord care for the parent of a newborn. Which instructions would you include in the teaching?

• A. Contact provider if the cord turns black
• B. Clean the base of the cord with hydrogen peroxide daily
• C. Keep the cord dry until it falls off
• D. The cord stump will fall off in ten days

Correct answer: C

Rationale: The correct instruction to include in the teaching for cord care is to keep the cord dry until it falls off naturally. This helps prevent infection, as the cord typically falls off in 10-14 days, not within five days. Instructing the parent to contact the provider if the cord turns black (Choice A) is important to monitor for signs of infection. Cleaning the base of the cord with hydrogen peroxide daily (Choice B) is not recommended as it can delay healing. Stating that the cord stump will fall off in ten days (Choice D) provides a more accurate timeframe compared to the initial estimation of five days.

4. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following findings indicates she is dehydrated?

• A. Urine specific gravity of 1.020
• B. Urine specific gravity of 1.035
• C. Decreased skin turgor
• D. Decreased heart rate

Correct answer: B

Rationale: The correct answer is B. A urine specific gravity greater than 1.030 is indicative of dehydration as it reflects concentrated urine. Choice A is incorrect as a specific gravity of 1.020 is within the normal range. Choice C, decreased skin turgor, can be a sign of dehydration but is not as specific as urine specific gravity. Choice D, decreased heart rate, is not typically a direct indicator of dehydration.

5. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.
