The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?
- A. 0.35 ml
- B. 0.40 ml
- C. 0.50 ml
- D. 0.45 ml
Correct Answer: B
Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

The nurse is assessing a client with left-sided heart failure. Which clinical finding requires immediate intervention?
- A. Jugular venous distention
- B. Shortness of breath
- C. Crackles in the lungs
- D. Peripheral edema
Correct Answer: C
Rationale: Corrected Rationale: In a client with left-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention to prevent worsening heart failure symptoms and respiratory distress. Jugular venous distention, shortness of breath, and peripheral edema are also common in heart failure but are not as critical as crackles in the lungs because they may indicate fluid overload or right-sided heart failure, which are important to address but not as urgently as managing pulmonary congestion.
The nurse is reinforcing home care instructions with a client who is being discharged following a transurethral resection of the prostate (TURP). Which intervention is most important for the nurse to include in the client's instructions?
- A. Avoid strenuous activity for 6 weeks.
- B. Report fresh blood in the urine.
- C. Take acetaminophen for fever of 101°F.
- D. Consume 6 to 8 glasses of water daily.
Correct Answer: B
Rationale: Reporting fresh blood in the urine is crucial following a TURP procedure as it may indicate a complication such as bleeding or clot formation. This symptom requires immediate attention to prevent further complications. Choices A, C, and D are important aspects of post-TURP care, but identifying and reporting fresh blood in the urine take precedence due to its association with potential serious complications.
A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct Answer: C
Rationale: The correct answer is C. Use of accessory muscles is the most concerning finding in a client with COPD experiencing an exacerbation. This indicates increased work of breathing and can be a sign of respiratory failure, requiring immediate intervention. Oxygen saturation of 90% is low but not as concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute can be within normal limits. Inspiratory crackles may be present in COPD due to airway inflammation but are not as concerning as the use of accessory muscles.
A client's subjective data includes dysuria, urgency, and urinary frequency. What action should the nurse implement next?
- A. Collect a clean-catch specimen
- B. Administer prescribed antibiotics
- C. Perform a bladder scan
- D. Increase the client's fluid intake
Correct Answer: A
Rationale: The correct action for the nurse to implement next is to collect a clean-catch specimen. This is essential to diagnose the cause of the client's symptoms accurately before initiating any treatment. Administering antibiotics (Choice B) without confirming the diagnosis through a specimen collection can be inappropriate and potentially harmful. Performing a bladder scan (Choice C) may not provide the necessary information to identify the specific cause of the symptoms. Increasing the client's fluid intake (Choice D) is a general recommendation and may not address the underlying issue causing the symptoms.
A 7-year-old boy is brought to the clinic because of facial edema. He reports that he has been voiding small amounts of dark, cloudy, tea-colored urine. The parents state that their son had a sore throat 2 weeks earlier, but it has resolved. After assessing the child's vital signs and weight, what intervention should the nurse implement next?
- A. Perform an otoscopic examination
- B. Measure the child's abdominal girth
- C. Collect a urine specimen for routine urinalysis
- D. Obtain a blood specimen for serum electrolytes
Correct Answer: C
Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.
