Daily weights are being recorded for the patient with a urine output that has been less than the intravenous and oral intake. The weight yesterday was 97.5 kg. This morning it is 99 kg. The nurse understands that this corresponds to a(n)
- A. fluid retention of 1.5 liters.
- B. fluid loss of 1.5 liters.
- C. equal intake and output due to insensible losses.
- D. fluid loss of 0.5 liters.
Correct Answer: A
Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 97.5 kg to 99 kg indicates an increase in fluid retention. This difference of 1.5 kg corresponds to fluid retention of 1.5 liters, as 1 liter of water weighs approximately 1 kg. This weight gain suggests that the patient is retaining more fluid than they are excreting, leading to an increase in weight.
Incorrect choices:
B: fluid loss of 1.5 liters - This is incorrect because the weight increased, indicating fluid retention.
C: equal intake and output due to insensible losses - This is incorrect as weight increased, showing an imbalance in intake and output.
D: fluid loss of 0.5 liters - This is incorrect as the weight increased, indicating fluid retention, not loss.

When assessing an older patient admitted to the emergency department (ED) with a broken arm and facial bruises, the nurse observes several additional bruises in various stages of healing. Which statement or question by the nurse is most appropriate?
- A. Do you feel safe in your home?
- B. You should not return to your home.
- C. Would you like to see a social worker?
- D. I need to report my concerns to the police.
Correct Answer: A
Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.
The nurse obtains a heart rate of 92 and a blood pressure of 110/76 prior to administering a scheduled dose of verapamil (Calan) for a client with atrial flutter. Which action should the nurse implement?
- A. Give intravenous (IV) calcium gluconate.
- B. Withhold the drug and notify the healthcare provider.
- C. Administer the dose as prescribed.
- D. Recheck the vital signs in 30 minutes and then administer the dose.
Correct Answer: C
Rationale: The correct answer is C: Administer the dose as prescribed. Verapamil is a calcium channel blocker used to treat atrial flutter. The vital signs obtained are within normal range for this medication. A heart rate of 92 and blood pressure of 110/76 are not contraindications for administering verapamil. Option A is incorrect as calcium gluconate is not indicated in this situation. Option B is incorrect because the vital signs are stable and do not warrant withholding the medication. Option D is incorrect as there is no need to delay the administration of verapamil based on the vital signs provided.
What diagnostic procedure is required to make a definitive diagnosis of pulmonary embolism?
- A. Arterial blood gas (ABG) analysis.
- B. Chest x-ray examination.
- C. High resolution multidetector CT angiogram.
- D. Ventilation-perfusion scanning.
Correct Answer: C
Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries.
A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism.
B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism.
D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.
Which of the following situations may result in a low cardiac output and low cardiac index? (Select all that apply.)
- A. Exercise
- B. Hypovolemia
- C. Myocardial infarction
- D. Shock
Correct Answer: B
Rationale: Certainly. Hypovolemia, or low blood volume, can lead to low cardiac output and cardiac index because the heart has less blood to pump, resulting in reduced circulation. Exercise typically increases cardiac output to meet increased demand. Myocardial infarction may reduce cardiac output temporarily, but not consistently. Shock, a condition where the body's tissues do not receive enough oxygen and nutrients, can lead to low cardiac output, making it a possible cause.
Which action will the nurse need to do when preparing to assist with the insertion of a pulmonary artery catheter?
- A. Determine if the cardiac troponin level is elevated.
- B. Auscultate heart and breath sounds during insertion.
- C. Place the patient on NPO status before the procedure.
- D. Attach cardiac monitoring leads before the procedure.
Correct Answer: D
Rationale: The correct answer is D: Attach cardiac monitoring leads before the procedure. This is essential to monitor the patient's cardiac rhythm and detect any abnormalities during catheter insertion. Cardiac monitoring leads provide real-time information on the patient's heart rate and rhythm, allowing the nurse to promptly address any complications.
A: Determining if the cardiac troponin level is elevated is not directly related to assisting with pulmonary artery catheter insertion.
B: Auscultating heart and breath sounds during insertion is important but does not take precedence over attaching cardiac monitoring leads.
C: Placing the patient on NPO status before the procedure may be necessary for other procedures, but it is not specifically required for assisting with pulmonary artery catheter insertion.
