Nokea
A 55-year-old patient admitted with an abrupt onset of jaundice and nausea has abnormal liver function studies, but serologic testing is negative for viral causes of hepatitis. Which question by the nurse is most appropriate?
- A. Is there any history of IV drug use?
- B. Do you use any over-the-counter drugs?
- C. Are you taking corticosteroids for any reason?
- D. Have you recently traveled to a foreign country?
Correct Answer: B
Rationale: The most appropriate question for the nurse to ask in this scenario is whether the patient uses any over-the-counter drugs. The patient's symptoms, negative serologic testing for viral hepatitis, and sudden onset of symptoms point towards toxic hepatitis, which can be triggered by commonly used over-the-counter medications like acetaminophen (Tylenol). Asking about IV drug use is relevant for viral hepatitis, not toxic hepatitis. Inquiring about recent travel to a foreign country is more pertinent to potential exposure to infectious agents causing viral hepatitis. Corticosteroid use is not typically associated with the symptoms described in the case.

While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?
- A. Stop the saline infusion immediately
- B. Notify the physician
- C. Elevate the patient's legs
- D. Continue the infusion, as these findings are normal
Correct Answer: A
Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:
- A. Expose the cast to air and turn the child frequently.
- B. Use a heat lamp to reduce the drying time.
- C. Handle the cast with the abductor bar.
- D. Turn the child as little as possible.
Correct Answer: A
Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.
A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:
- A. Has increased airway obstruction.
- B. Has improved airway obstruction.
- C. Needs to be suctioned.
- D. Exhibits hyperventilation.
Correct Answer: B
Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.
A newborn infant in the nursery has developed vomiting, poor feeding, lethargy, and respiratory distress, and has been diagnosed with necrotizing enterocolitis. Which of the following nursing interventions is most appropriate for this infant?
- A. Feed the infant 30 cc of sterile water
- B. Position the infant on his back
- C. Administer antibiotics as ordered
- D. Allow the infant to breastfeed
Correct Answer: C
Rationale: Necrotizing enterocolitis (NEC) is a serious condition characterized by ischemic bowel, leading to gastrointestinal symptoms, lethargy, poor feeding, and respiratory distress. In the management of NEC, it is crucial to stop oral feedings, insert a nasogastric tube for decompression, and administer antibiotics as prescribed by the physician. Therefore, the most appropriate nursing intervention for an infant with NEC is to administer antibiotics as ordered.
Choice A, feeding the infant sterile water, is incorrect because oral feedings should be stopped in NEC. Choice B, positioning the infant on his back, is not directly related to the treatment of NEC. Choice D, allowing the infant to breastfeed, is contraindicated in NEC as oral feedings should be ceased to prevent further complications.
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.
