Nursing Elites

1. The patient is receiving sulfadiazine. The healthcare provider knows that this patient’s daily fluid intake should be at least which amount?

• A. 1000 mL/day
• B. 1200 mL/day
• C. 2000 mL/day
• D. 2400 mL/day

Correct answer: C

Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.

2. The patient has a heart rate of 98 beats per minute and a blood pressure of 82/58 mm Hg, is lethargic, complaining of muscle weakness, and has had gastroenteritis for several days. Based on these findings, which sodium value would the nurse expect?

• A. 126 mEq/L
• B. 140 mEq/L
• C. 145 mEq/L
• D. 158 mEq/L

Correct answer: A

Rationale: The patient's presentation of tachycardia, hypotension, lethargy, muscle weakness, and gastroenteritis suggests hyponatremia. Hyponatremia is characterized by a serum sodium level below the normal range of 135-145 mEq/L. A serum sodium level of 126 mEq/L falls significantly below this range, indicating hyponatremia. Choice B (140 mEq/L) and Choice C (145 mEq/L) are within the normal range for serum sodium levels and would not explain the patient's symptoms. Choice D (158 mEq/L) is above the normal range and would indicate hypernatremia, which is not consistent with the patient's presentation.

3. 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.

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. A client is recovering after a nephrostomy tube was placed 6 hours ago. The nurse notes drainage in the tube has decreased from 40 mL/hr to 12 mL over the last hour. Which action should the nurse take?

• A. Document the finding in the client’s record.
• B. Evaluate the tube as working in the hand-off report.
• C. Clamp the tube in preparation for removing it.
• D. Assess the client’s abdomen and vital signs.

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to assess the client’s abdomen and vital signs. The nephrostomy tube should have a consistent amount of drainage, and a decrease may indicate obstruction. Before notifying the provider, the nurse must assess the client for pain, distention, and changes in vital signs. This assessment is crucial to gather essential information to report accurately. Documenting the finding without further assessment may delay necessary intervention. Evaluating the tube as working in the hand-off report or clamping the tube prematurely are not appropriate actions and could lead to complications if there is an obstruction.
