A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?
- A. Reposition the nasal cannula
- B. Lower the oxygen rate
- C. Encourage the client to cough and deep breathe
- D. Monitor the client's oxygen saturation level
Correct Answer: B
Rationale: The correct answer is B: Lower the oxygen rate. Increasing oxygen flow too quickly can lead to oxygen toxicity in COPD patients, causing symptoms like lethargy and confusion. Lowering the oxygen rate will help alleviate the symptoms and prevent further harm. Repositioning the nasal cannula (choice A) is not the priority in this situation. Encouraging coughing and deep breathing (choice C) may not address the immediate issue of oxygen toxicity. Monitoring oxygen saturation (choice D) is important but should follow lowering the oxygen rate to address the current symptoms.

The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
- A. Blood glucose of 140 mg/dL
- B. White blood cell count of 8000/mm³
- C. Serum potassium of 3.8 mEq/L
- D. Serum calcium of 7.8 mg/dL
Correct Answer: D
Rationale: The correct answer is D: Serum calcium of 7.8 mg/dL. This finding indicates hypocalcemia, which can lead to life-threatening cardiac arrhythmias. Low calcium levels can be caused by TPN administration or poor calcium absorption following bowel resection. Immediate intervention may include administering IV calcium gluconate.
A: Blood glucose of 140 mg/dL is within the normal range and not an immediate concern.
B: White blood cell count of 8000/mm³ is within the normal range and does not require immediate intervention.
C: Serum potassium of 3.8 mEq/L is within the normal range and does not pose an immediate threat.
When caring for a laboring client whose contractions are occurring every 2-3 minutes, the nurse should document that the pump is infusing how many ml/hour?
- A. 5
- B. 10
- C. 15
- D. 20
Correct Answer: A
Rationale: The correct answer is A: 5 ml/hour. To calculate the infusion rate, you need to divide the total amount infused by the total time in hours. Given contractions every 2-3 minutes, which is equivalent to 20-30 contractions per hour, the pump should infuse at 5 ml/hour to ensure proper medication delivery. Choices B, C, and D are incorrect because they do not correspond to the frequency of contractions and may lead to under or overmedication.
A 9-year-old received a short arm cast for a right radius. To relieve itching under the child's cast, which instructions should the nurse provide to the parents?
- A. Blow cool air from a hair dryer under the cast
- B. Twist the cast back and forth
- C. Shake powder into the cast
- D. Push a pencil under the cast edge
Correct Answer: A
Rationale: The correct answer is A: Blow cool air from a hair dryer under the cast. This method helps to relieve itching by providing airflow without causing damage to the cast or skin. It is safe and effective.
Choice B: Twisting the cast back and forth may cause discomfort or injury to the child's arm.
Choice C: Shaking powder into the cast can create a mess and may lead to skin irritation or infection.
Choice D: Pushing a pencil under the cast edge can cause damage to the skin or lead to complications.
The nurse is caring for a 10-year-old diagnosed with acute glomerulonephritis. Which outcome is the priority for this child?
- A. Activity tolerance as evidenced by appropriate age-level activities being performed
- B. Absence of skin breakdown as evidenced by intact skin and absence of redness
- C. Maintaining adequate nutritional status as evidenced by stable weight without gain or loss
- D. Maintaining fluid balance as evidenced by a urine output of 1 to 2 ml/kg/hr
Correct Answer: D
Rationale: The correct answer is D. In acute glomerulonephritis, the kidneys are inflamed, affecting fluid balance. Monitoring urine output of 1 to 2 ml/kg/hr is crucial to assess kidney function and prevent fluid overload or dehydration. This is the priority outcome as it directly reflects kidney function and overall fluid balance.
A: Activity tolerance is important but not the priority in acute glomerulonephritis.
B: Absence of skin breakdown is important for overall health but not directly related to the condition.
C: Nutritional status is important, but fluid balance takes precedence in managing acute glomerulonephritis.
In summary, maintaining fluid balance is crucial in managing acute glomerulonephritis as it directly reflects kidney function, while the other options are important but not the priority in this scenario.
In preparing to administer a scheduled dose of intravenous furosemide (Lasix) to a client with heart failure, the nurse notes that the client's B-Type Naturetic peptide (BNP) is elevated. What action should the nurse take?
- A. Measure the client's oxygen saturation before taking further action
- B. Administer a PRN dose of nitroglycerin (Nitrostat)
- C. Administer the dose of furosemide as scheduled
- D. Hold the dose of furosemide until contacting the healthcare provider
Correct Answer: C
Rationale: The correct action is to administer the dose of furosemide as scheduled (Choice C) because an elevated BNP level indicates increased fluid volume and pressure in the heart. Furosemide is a diuretic that helps reduce fluid overload in heart failure patients, which can alleviate symptoms and improve cardiac function. Holding the dose (Choice D) could delay necessary treatment, potentially worsening the patient's condition. Measuring oxygen saturation (Choice A) is important but not the immediate priority in this situation. Administering nitroglycerin (Choice B) is not appropriate as it is used for chest pain related to angina, not for treating elevated BNP levels in heart failure.
