A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Arterial blood gases (ABGs)
- D. Echocardiogram
Correct Answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of CAD and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify signs of ischemia or a heart attack. While other diagnostic tests like chest X-ray, arterial blood gases, and echocardiogram may also be necessary in the evaluation of chest pain, they do not provide the initial direct assessment of cardiac ischemia that an ECG does.

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 with a tracheostomy has thick, tenacious secretions. Which intervention should the nurse implement first?
- A. Perform deep suctioning every 2 to 4 hours.
- B. Encourage the client to drink plenty of fluids.
- C. Increase humidity in the client's room.
- D. Administer a mucolytic agent.
Correct Answer: C
Rationale: Increasing humidity in the client's room can help liquefy thick secretions and facilitate easier airway clearance in a client with a tracheostomy. This intervention should be implemented first as it is non-invasive and can often effectively address the issue of thick secretions. Performing deep suctioning (Choice A) should not be the first intervention as it is more invasive and should be done based on assessment findings. Encouraging the client to drink plenty of fluids (Choice B) is beneficial but may not provide immediate relief for thick secretions. Administering a mucolytic agent (Choice D) requires a healthcare provider's prescription and should be based on assessment data and the client's condition.
A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which assessment finding is most concerning?
- A. INR of 3.5
- B. Prothrombin time (PT) of 15 seconds
- C. Headache
- D. Blood pressure of 140/90 mmHg
Correct Answer: C
Rationale: The correct answer is C. A headache in a client with a history of atrial fibrillation receiving warfarin (Coumadin) is concerning as it may indicate bleeding, which requires immediate assessment and intervention. Headaches can be a symptom of increased intracranial pressure due to bleeding, especially in patients on anticoagulants. Options A and B are within acceptable ranges for a client on warfarin therapy, indicating that the medication is effectively managing the clotting times. Option D, a blood pressure of 140/90 mmHg, while elevated, is not directly related to the client's condition of atrial fibrillation and warfarin therapy.
The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?
- A. Serum potassium of 3.0 mEq/L
- B. Serum sodium of 135 mEq/L
- C. Serum creatinine of 1.8 mg/dL
- D. Blood glucose of 200 mg/dL
Correct Answer: A
Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.
The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which assessment finding requires immediate intervention?
- A. Use of accessory muscles
- B. Oxygen saturation of 90%
- C. Respiratory rate of 24 breaths per minute
- D. Blood pressure of 110/70 mmHg
Correct Answer: A
Rationale: The correct answer is A: Use of accessory muscles. This finding indicates increased work of breathing in a client with COPD and may signal respiratory failure, requiring immediate intervention. In COPD, the use of accessory muscles suggests that the client is in distress and struggling to breathe effectively. Oxygen saturation of 90% is within an acceptable range for a client with COPD receiving supplemental oxygen and does not require immediate intervention. A respiratory rate of 24 breaths per minute is slightly elevated but not a critical finding. A blood pressure of 110/70 mmHg is within the normal range for an adult and does not indicate a need for immediate intervention in this scenario.
