1. A client with a completed ischemic stroke has a blood pressure of 180/90 mm Hg. Which action should the nurse implement?
- A. Position the head of the bed (HOB) flat.
- B. Withhold intravenous fluids.
- C. Administer a bolus of IV fluids.
- D. Give an antihypertensive medication.
Correct answer: D
Rationale: In a client with a completed ischemic stroke, an elevated blood pressure like 180/90 mm Hg requires immediate intervention to prevent further damage. Giving an antihypertensive medication is essential to reduce the risk of recurrent stroke or complications related to hypertension. Positioning the head of the bed flat, withholding IV fluids, or administering a bolus of IV fluids are not appropriate actions for managing elevated blood pressure in this scenario and may not address the underlying cause of the hypertension or prevent potential complications.
2. A nurse is preparing for intershift report when a nurse’s aide pulls an emergency call light in a client’s room. Upon answering the light, the nurse finds a client who returned from surgery earlier in the day experiencing tachycardia and tachypnea. The client’s blood pressure is 88/60 mm Hg. Which action should the nurse take first?
- A. Calling the physician
- B. Checking the hourly urine output
- C. Checking the IV site for infiltration
- D. Placing the client in a modified Trendelenburg position
Correct answer: D
Rationale: The client is exhibiting signs of shock, indicated by tachycardia, tachypnea, and hypotension. Placing the client in a modified Trendelenburg position is the initial action to improve venous return, cardiac output, and subsequently increase blood pressure. This position helps redistribute blood flow to vital organs. Calling the physician should follow once immediate intervention has been initiated. Checking the hourly urine output and IV site are important assessments but are secondary to addressing the client's hemodynamic instability and potential for shock.
3. A client who underwent surgery and experienced significant blood loss is being cared for by a nurse. Which findings by the nurse should prompt immediate action to prevent acute kidney injury? (Select all that apply.)
- A. Urine output of 100 mL in 4 hours
- B. Large amount of sediment in the urine
- C. A & B
- D. Amber, odorless urine
Correct answer: C
Rationale: The nurse must monitor for signs of acute kidney injury in a postoperative client who had major blood loss. Low urine output, presence of sediment in the urine, and low blood pressure should raise concerns and be reported to the healthcare provider promptly. Postoperatively, assessing urine characteristics is crucial. Sediment, hematuria, and urine output less than 0.5 mL/kg/hour for 3 to 4 hours should be reported. While a urine output of 100 mL in 4 hours is low, it should be compared to the recommended 0.5 mL/kg/hour over a longer period. Perfusion to the kidneys is a priority, hence the importance of addressing low blood pressure. Amber, odorless urine is considered normal and does not indicate an immediate concern for acute kidney injury, unlike low urine output and presence of sediment.
4. After checking the urinary drainage system for kinks in the tubing, the nurse determines that a client who has returned from the post-anesthesia care has a dark, concentrated urinary output of 54 ml for the last 2 hours. What priority nursing action should be implemented?
- A. Report the findings to the surgeon.
- B. Irrigate the indwelling urinary catheter.
- C. Apply manual pressure to the bladder.
- D. Increase the IV flow rate for 15 minutes.
Correct answer: A
Rationale: In this situation, the nurse's priority action should be to report the findings to the surgeon. An adult should typically produce about 60 ml of urine per hour, so a dark, concentrated, and low urine output of 54 ml over 2 hours raises concerns. This change in urine output may indicate issues such as dehydration, renal problems, or inadequate fluid intake. Reporting this finding to the surgeon is crucial to ensure appropriate evaluation and intervention. Irrigating the catheter, applying manual pressure to the bladder, or increasing the IV flow rate are not appropriate actions based on the information provided and could potentially worsen the situation.
5. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 62, PaCO2 59, and HCO3. Which statement describes the most likely cause of the simultaneous increase in both the PaO2 and the PaCO2?
- A. The hypercapnia resulted from the rapid respirations.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client had a pneumothorax which restricted ventilation.
- D. The client had a pulmonary embolism that reduced perfusion.
Correct answer: B
Rationale: In patients with COPD, oxygen therapy can reduce the hypoxic drive, which is the primary stimulus for breathing in these individuals. By providing supplemental oxygen, the hypoxic drive is diminished, resulting in decreased respiratory effort. As a consequence, the PaO2 may increase due to the supplemental oxygen, but this can lead to a decrease in the respiratory drive and subsequent retention of carbon dioxide, causing an increase in PaCO2 levels. Option A is incorrect because rapid respirations would typically lower PaCO2 levels. Option C is incorrect as a pneumothorax would lead to impaired gas exchange and decreased PaO2 levels without necessarily affecting PaCO2 levels. Option D is incorrect as a pulmonary embolism would typically result in ventilation-perfusion mismatch and decreased PaO2 levels without directly impacting PaCO2 levels.
