Nursing Elites

1. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

2. 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.

3. The nurse is assessing a client with left-sided heart failure. Which finding requires immediate intervention?

• A. Shortness of breath
• B. Jugular venous distention
• C. Crackles in the lungs
• D. Peripheral edema

Correct answer: C

Rationale: Crackles in the lungs indicate pulmonary congestion in a client with left-sided heart failure and require immediate intervention to prevent respiratory failure. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potentially respiratory distress. Shortness of breath, jugular venous distention, and peripheral edema are common manifestations of heart failure but do not directly indicate acute respiratory compromise like crackles in the lungs do.

4. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be closely monitored before the procedure?

• A. Serum creatinine of 2.0 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum calcium of 8.0 mg/dl
• D. Hemoglobin of 12 g/dl

Correct answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.

5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which assessment finding should be reported to the healthcare provider immediately?

• A. Blood pressure of 110/70 mmHg
• B. Heart rate of 80 beats per minute
• C. Fever of 100.4°F
• D. Respiratory rate of 24 breaths per minute

Correct answer: C

Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis as it may indicate an underlying infection, which can lead to serious complications in this population. Elevated body temperature can be a sign of sepsis, which requires immediate attention to prevent further deterioration. Reporting this finding promptly allows for timely intervention. Choices A, B, and D are within normal ranges and do not pose an immediate threat to the client's well-being in the context of preparing for hemodialysis.
