Nursing Elites

1. In a patient with chronic kidney disease, which of the following is a common electrolyte imbalance?

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

Correct answer: A

Rationale: Hyperkalemia is a common electrolyte imbalance in chronic kidney disease. In chronic kidney disease, the kidneys' reduced function leads to the decreased excretion of potassium, resulting in elevated serum potassium levels. This can be dangerous as hyperkalemia can lead to life-threatening arrhythmias. Hypokalemia (Choice B) is less common in chronic kidney disease as the impaired kidneys tend to retain potassium. Hypernatremia (Choice C) is more commonly seen in conditions such as dehydration, not primarily in chronic kidney disease. Hyponatremia (Choice D) is also possible in chronic kidney disease but is less common compared to hyperkalemia.

2. A client is receiving a continuous infusion of normal saline at 125 ml/hour post abdominal surgery. The client is drowsy and complaining of constant abdominal pain and a headache. Urine output is 800 ml over the past 24 hours with a central venous pressure of 15 mmHg. The nurse notes respiratory crackles and bounding central pulse. Vital signs: temperature 101.2 F (38.4 C), heart rate 96 beats/minute, respiration 24 breaths/minute, and blood pressure of 160/90 mmHg. Which intervention should the nurse implement first?

• A. Calculate total intake and output for the last 24 hours.
• B. Administer a PRN dose of acetaminophen.
• C. Decrease IV fluids to a keep vein open (KVO) rate.
• D. Review the last administration of IV pain medication.

Correct answer: C

Rationale: In this scenario, the client is showing signs of fluid volume excess, such as drowsiness, abdominal pain, headache, crackles in the lungs, bounding pulse, and elevated blood pressure. Decreasing the IV fluids to a keep vein open (KVO) rate is crucial to prevent further fluid overload. This intervention helps in balancing fluid intake and output to prevent complications associated with fluid volume excess. Calculating total intake and output (Choice A) may be necessary but not the immediate priority in managing fluid overload. Administering acetaminophen (Choice B) may help with managing the fever but does not address the underlying issue of fluid overload. Reviewing the last administration of IV pain medication (Choice D) is not the priority in this situation where fluid overload is a concern.

3. A client with cholelithiasis is admitted with jaundice due to obstruction of the common bile duct. Which finding is most important for the nurse to report to the healthcare provider?

• A. Distended, hard, and rigid abdomen
• B. Clay-colored stool
• C. Radiating sharp pain in the right shoulder
• D. Bile-stained emesis

Correct answer: A

Rationale: The most important finding for the nurse to report to the healthcare provider in a client with cholelithiasis and jaundice due to common bile duct obstruction is a distended, hard, and rigid abdomen. These signs may indicate a possible surgical emergency, such as a complication like gallbladder perforation or peritonitis, which require immediate intervention. Clay-colored stool is associated with obstructive jaundice but does not indicate an acute surgical emergency. Radiating sharp pain in the right shoulder (referred pain from the diaphragm) and bile-stained emesis may also be seen in cholelithiasis but are not as urgent as a distended, hard, and rigid abdomen.

4. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?

• A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
• B. A serum drug level greater than the MEC broadens the spectrum of the drug.
• C. A serum drug level greater than the MEC helps eradicate bacterial infections.
• D. A serum drug level greater than the MEC increases the therapeutic index.

Correct answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.

5. The nurse is obtaining a health history from a new client who has a history of kidney stones. Which statement by the client indicates an increased risk for renal calculi?

• A. Eats a vegetarian diet with cheese 2 to 3 times a day
• B. Experiences additional stress since adopting a child
• C. Jogs more frequently than usual daily routine
• D. Drinks several bottles of carbonated water daily

Correct answer: D

Rationale: The correct answer is D. Drinking several bottles of carbonated water daily may contribute to renal calculi formation due to the high mineral content. Carbonated drinks can increase the risk of kidney stones due to their high levels of phosphoric acid and caffeine, which can lead to the formation of crystals in the urine. Choices A, B, and C are less likely to directly contribute to an increased risk of renal calculi compared to the excessive consumption of carbonated water.
