Nokea
The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:
- A. Urinary output of 30 ml per hour
- B. No complaints of thirst
- C. Increased hematocrit
- D. Good skin turgor around burn
Correct Answer: A
Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

Which finding is most important for the nurse to communicate to the health care provider about a patient who received a liver transplant 1 week ago?
- A. Dry palpebral and oral mucosa
- B. Crackles at bilateral lung bases
- C. Temperature 100.8?F (38.2?C)
- D. No bowel movement for 4 days
Correct Answer: C
Rationale: The correct answer is the patient's temperature of 100.8°F (38.2°C). In a patient who received a liver transplant 1 week ago, a fever is a significant finding that should be promptly communicated to the health care provider. Post-transplant patients are at high risk of infections, and fever can often be the initial indicator of an underlying infectious process. The other findings listed in choices A, B, and D are important and should be addressed, but they do not take precedence over a potential infection post-liver transplant. Dry palpebral and oral mucosa may indicate dehydration, crackles at bilateral lung bases may suggest fluid overload or infection, and no bowel movement for 4 days could indicate a bowel obstruction or ileus. However, in the context of a recent liver transplant, an elevated temperature is the most concerning and requires immediate attention to rule out infection.
When taking the blood pressure (BP) on the right arm of a patient with severe acute pancreatitis, the nurse notices carpal spasms of the patient's right hand. Which action should the nurse take next?
- A. Ask the patient about any arm pain.
- B. Retake the patient's blood pressure.
- C. Check the calcium level in the chart.
- D. Notify the healthcare provider immediately.
Correct Answer: C
Rationale: In this scenario, the nurse observed carpal spasms in the patient's right hand, indicating a positive Trousseau's sign, which is associated with hypocalcemia. Patients with acute pancreatitis are at risk for hypocalcemia, hence the nurse should promptly check the calcium level in the chart to assess the patient's condition. Notifying the healthcare provider comes after confirming the calcium level. There is no indication to ask about arm pain or to retake the blood pressure, as the primary concern is addressing the potential hypocalcemia.
A patient with severe Gastroesophageal Reflux Disease is receiving discharge teaching. Which of these statements by the patient indicates a need for more teaching?
- A. I'm going to limit my meals to 2-3 per day to reduce acid secretion.''
- B. I'm going to make sure to remain upright after meals and elevate my head when I sleep.''
- C. I won't be drinking tea or coffee or eating chocolate anymore.''
- D. I'm going to start trying to lose some weight.''
Correct Answer: A
Rationale: The correct answer is ''I'm going to limit my meals to 2-3 per day to reduce acid secretion.'' This statement indicates a need for more teaching because large meals increase the volume and pressure in the stomach, delaying gastric emptying, and worsening symptoms of Gastroesophageal Reflux Disease (GERD). The recommended approach is to eat smaller, more frequent meals (4-6 small meals a day) to reduce acid reflux. Choices B, C, and D demonstrate good understanding of GERD management by highlighting the importance of staying upright after meals, avoiding trigger foods like tea, coffee, and chocolate, and addressing weight management, which are all appropriate strategies to manage GERD symptoms.
A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?
- A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
- B. The ventilator coordinates delivered breaths with the client's respiratory efforts
- C. The ventilator provides a supplemental breath for every third breath of the client
- D. The ventilator provides breaths during the expiratory phase of the client's respirations
Correct Answer: B
Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor
- A. bilirubin levels.
- B. ammonia levels.
- C. potassium levels.
- D. prothrombin time.
Correct Answer: B
Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.
