A nurse is preparing to administer fluconazole 400 mg by intermittent IV bolus daily. Available is fluconazole 400 mg in 0.9% sodium chloride (NaCl) 200 mL to infuse over 2 hours. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 100
Rationale: Correct Answer: 100
Rationale: To calculate the IV pump rate, use the formula: (Volume to be infused in mL) / (Time in hours). In this case, 200 mL over 2 hours. 200 / 2 = 100 mL/hr.
Summary:
A. Incorrect. Not the correct calculation for the IV pump rate.
B. Incorrect. Not the correct calculation for the IV pump rate.
C. Incorrect. Not the correct calculation for the IV pump rate.
D. Incorrect. Not the correct calculation for the IV pump rate.
E. Incorrect. Not the correct calculation for the IV pump rate.
F. Incorrect. Not the correct calculation for the IV pump rate.
G. Incorrect. Not the correct calculation for the IV pump rate.

A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
- A. Hypophosphatemia
- B. Hyperkalemia
- C. Hypercalcemia
- D. Hypernatremia
Correct Answer: B
Rationale: The correct answer is B: Hyperkalemia. In prerenal AKI, decreased blood flow to the kidneys leads to reduced filtration and impaired excretion of potassium, resulting in hyperkalemia. Hypophosphatemia (A), hypercalcemia (C), and hypernatremia (D) are not typically associated with prerenal AKI. In prerenal AKI, there is usually no significant change in phosphate levels, calcium levels are typically normal or low due to volume depletion, and sodium levels may be normal or decreased due to reduced renal perfusion.
A nurse is caring for a client who has prostate cancer. The nurse should expect the provider to prescribe which of the following medications for this client?
- A. Tamoxifen
- B. Leuprolide
- C. Finasteride
- D. Cyclophosphamide
Correct Answer: B
Rationale: The correct answer is B: Leuprolide. Leuprolide is a gonadotropin-releasing hormone agonist that suppresses testosterone production, which can help slow the growth of prostate cancer. Tamoxifen (A) is used for breast cancer, Finasteride (C) is used for benign prostatic hyperplasia, and Cyclophosphamide (D) is a chemotherapy drug for various cancers. Therefore, in this case, the most appropriate medication for prostate cancer would be Leuprolide (B).
A nurse is caring for a client who suspects recent exposure to inhalation anthrax. Which of the following findings indicate possible exposure?
- A. Vesicles on the skin
- B. Respiratory failure
- C. Flu-like symptoms
- D. Coughing of blood
Correct Answer: B
Rationale: The correct answer is B: Respiratory failure. Inhalation anthrax primarily affects the respiratory system, causing symptoms such as difficulty breathing, cough, and chest discomfort. Respiratory failure can occur in severe cases. Vesicles on the skin (A) are not typically associated with inhalation anthrax. Flu-like symptoms (C) are nonspecific and can be seen with various infections. Coughing of blood (D) is not a common symptom of inhalation anthrax. Therefore, the most indicative finding of possible exposure to inhalation anthrax is respiratory failure.
A nurse is caring for a client who has acute respiratory distress syndrome (ARDS) and requires mechanical ventilation. The client receives a prescription for pancuronium. The nurse recognizes that this medication is for which of the following purposes?
- A. Induce sedation.
- B. Suppress respiratory effort.
- C. Decrease chest wall compliance.
- D. Decrease respiratory secretions.
Correct Answer: B
Rationale: The correct answer is B: Suppress respiratory effort. Pancuronium is a neuromuscular blocking agent that paralyzes skeletal muscles, including the muscles involved in breathing. In ARDS, the client may have difficulty breathing due to lung damage, so pancuronium can be used to facilitate mechanical ventilation by preventing respiratory muscle movement. This allows the ventilator to control the client's breathing without interference. The other choices are incorrect because pancuronium does not induce sedation (A), affect chest wall compliance (C), or decrease respiratory secretions (D). It solely works to suppress respiratory effort by blocking neuromuscular transmission.
A nurse is caring for a client who has hypertension and has a potassium level of 6.8 mEq/L. Which of the following actions should the nurse take?
- A. Obtain a 12-lead ECG.
- B. Suggest that the client use a salt substitute.
- C. Ask the client to add citrus juices and bananas to her diet.
- D. Obtain a blood sample for a serum sodium level.
Correct Answer: A
Rationale: The correct answer is A: Obtain a 12-lead ECG. A potassium level of 6.8 mEq/L is significantly elevated (normal range is 3.5-5.0 mEq/L) and can lead to serious cardiac complications, such as arrhythmias. Therefore, obtaining an ECG is crucial to assess the client's cardiac status. Choice B (salt substitute) is incorrect as it can further elevate potassium levels. Choice C (citrus juices and bananas) is incorrect as these are high-potassium foods that should be avoided. Choice D (serum sodium level) is irrelevant to the client's elevated potassium level.
