Question 1 of 5
A nurse is directed to administer a hypotonic intravenous solution. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:
Correct Answer: C
Rationale: Hypotonic solutions have lower osmolarity compared to the intracellular fluid, causing water to move into the cells by osmosis. This can lead to further swelling of the cells in the body. In the case of hypovolemia, the body is already experiencing a deficit of fluid and electrolytes, so administering a hypotonic solution like 0.90% sodium chloride would further exacerbate cellular swelling and potentially lead to cellular damage. Therefore, using 0.90% sodium chloride as a compensatory mechanism for hypovolemia would not be appropriate.
Question 2 of 5
What size of suction catheter would Wilma use for James, who is 6 feet 5 inches in height and weighing approximately 145 lbs?
Correct Answer: C
Rationale: The correct size of a suction catheter is usually determined by the patient's weight, rather than height. For James, who weighs approximately 145 lbs, a Fr. 10 suction catheter would be suitable. Suction catheter sizes typically range from Fr. 5 (smaller) to Fr. 18 (larger), with Fr. 10 being a common size for an adult patient of James' weight. Using a catheter that is too small may not effectively clear secretions, while one that is too big may cause discomfort or damage to the airways.
Question 3 of 5
Which patient should be monitored most closely for dehydration?
Correct Answer: A
Rationale: A patient with an ileostomy has an increased risk of dehydration because the ileostomy bypasses a significant portion of the small intestine where most of the water absorption occurs. As a result, the patient is more likely to experience fluid and electrolyte imbalances, leading to dehydration. It is important to monitor this patient closely for signs and symptoms of dehydration, such as decreased urine output, dry mouth, dark-colored urine, weakness, dizziness, and confusion, and take appropriate measures to ensure adequate hydration.
Question 4 of 5
A patient has orders to receive 1 L (1000 mL) of 5% dextrose and lactated Ringer's solution to be infused over 8 hours. How many millilitres will be infused per hour?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A 72-year-old chemist has left lower lobe pneumonia. His nurse checks his oxygen saturation and the result is 86%. Which of the ff. actions by the nurse is best?
Correct Answer: A
Rationale: An oxygen saturation (SaO2) level of 86% is significantly below the normal range of 95-100%. This indicates hypoxemia, which means the body is not getting enough oxygen. In a patient with pneumonia, low oxygen saturation can lead to further respiratory compromise and potential organ damage. Therefore, it is essential for the nurse to notify the physician promptly to obtain an order for supplemental oxygen to correct the hypoxemia and improve the patient's oxygen saturation levels. Delay in addressing low oxygen levels can have serious consequences for the patient's health and recovery.
