A 65-year-old male client with a history of smoking and high cholesterol is admitted with shortness of breath and 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. Pulmonary function tests (PFTs)

Correct Answer: A
Rationale: The correct answer is an Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia, especially given the client's symptoms and history. Chest X-ray (Choice B) may be ordered to evaluate the lungs but would not be the initial test for this client presenting with chest pain and shortness of breath. Arterial blood gases (ABGs) (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for a client with suspected cardiac issues. Pulmonary function tests (PFTs) (Choice D) are used to assess lung function and would not be the first test indicated in this scenario.

During a home visit, the nurse observed an elderly client with diabetes slip and fall. What action should the nurse take first?

• A. Give the client 4 ounces of orange juice
• B. Call 911 to summon emergency assistance
• C. Check the client for lacerations or fractures
• D. Assess client's blood sugar level

Correct Answer: C
Rationale: The correct first action for the nurse to take after an elderly client with diabetes slips and falls is to check the client for lacerations or fractures. This is crucial to assess for any immediate physical injuries that may need immediate attention. Giving orange juice or assessing the blood sugar level may be important later but checking for injuries takes precedence to ensure the client's safety and well-being. Calling 911 should be considered if there are severe injuries or if the client is in distress, but checking for lacerations or fractures is the priority at the moment.

The nurse is assessing a primigravida at 39-weeks gestation during a weekly prenatal visit. Which finding is most important for the nurse to report to the healthcare provider?

• A. Fetal heart rate of 200 beats/minute.
• B. Mild ankle edema.
• C. Complaints of back pain.
• D. Decreased fetal movements.

Correct Answer: A
Rationale: A fetal heart rate of 200 beats per minute is significantly elevated and requires immediate medical attention. This finding could indicate fetal distress, tachycardia, or other serious issues that need prompt evaluation. Mild ankle edema, complaints of back pain, and decreased fetal movements are common in pregnancy but are not as urgent or concerning as a high fetal heart rate.

The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?

• A. Serum potassium
• B. Hemoglobin
• C. Serum sodium
• D. White blood cell count

Correct Answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.

A client with chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?

• 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. The use of accessory muscles indicates increased work of breathing and can signal respiratory failure in a client with COPD. This finding requires immediate intervention to prevent further respiratory compromise. Oxygen saturation of 90% indicates some oxygenation impairment but may not necessitate immediate intervention. A respiratory rate of 24 breaths per minute is slightly elevated but does not indicate immediate respiratory distress. Inspiratory crackles may be present in pneumonia but do not require immediate intervention compared to the increased work of breathing indicated by the use of accessory muscles.
