Question 1 of 5
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?
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.
Question 2 of 5
Which laboratory test result should the nurse monitor to evaluate the effects of therapy for a 62-year-old female patient with acute pancreatitis?
Correct Answer: C
Rationale: The correct answer is C: Amylase. In acute pancreatitis, amylase levels are typically elevated. Monitoring amylase levels helps assess the effectiveness of therapy in managing the condition. Elevated amylase is a key indicator of pancreatic inflammation. Calcium (
Choice
A) levels may be affected in pancreatitis, but they are not the primary indicator for evaluating therapy effectiveness. Bilirubin (
Choice
B) and Potassium (
Choice
D) levels may also be altered in pancreatitis, but they are not specific markers for monitoring therapy response in acute pancreatitis.
Question 3 of 5
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?
Correct Answer: C
Rationale: Necrotizing enterocolitis (NE
C) 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.
Question 4 of 5
Why is it important to genotype HCV before initiating drug therapy?
Correct Answer: B
Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration.
Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
Question 5 of 5
A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:
Correct Answer: B
Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively.
Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions.
Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case.
Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.
