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 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.
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.
A male client with cancer who has lost 10 pounds during the last months tells the nurse that beef, chicken, and eggs, which used to be his favorite foods, now taste 'bitter'. He complains that he simply has no appetite. What action should the nurse implement?
- A. Suggest the use of alternative sources of protein such as dairy products and nuts.
- B. Encourage the client to eat smaller, more frequent meals.
- C. Offer nutritional supplements between meals.
- D. Discuss the possibility of appetite stimulants with the healthcare provider.
Correct Answer: A
Rationale: Offering alternative protein sources like dairy products and nuts can help maintain nutrition when the client finds certain foods unpalatable, as in this case where beef, chicken, and eggs taste 'bitter'. Encouraging smaller, more frequent meals may not address the issue of unpalatable foods. Offering nutritional supplements between meals may not specifically address the problem of protein intake. Discussing appetite stimulants should be considered after exploring less invasive options first.
An adult male who lives alone is brought to the Emergency Department by his daughter. He is unresponsive, with minimal respiratory effort, and his pupils are fixed and dilated. At the daughter's request, the client is intubated and mechanically ventilated. Which nursing intervention has the highest priority?
- A. Offer to notify the client's minister of his condition.
- B. Determine if the client has an executed living will.
- C. Provide the family with information about palliative care.
- D. Explore the possibility of organ donation with the family.
Correct Answer: B
Rationale: The highest priority nursing intervention in this scenario is to determine if the client has an executed living will. A living will provides guidance on the client's preferences for medical care in situations where they cannot communicate. This information is crucial in guiding the care team on how to proceed with treatment. Options A, C, and D, though important in certain circumstances, are not the highest priority in this situation where immediate decisions regarding the client's care need to be made.
A client with a history of myocardial infarction 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 myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.
