1. 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.

2. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?

• A. CK and Troponin
• B. BUN and Creatinine
• C. Amylase and Lipase
• D. HDL and LDL Cholesterol Levels

Correct answer: C

Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.

3. A mother brings her 26-month-old to the well-child clinic. She expresses frustration and anger due to her child's constant saying 'no' and refusal to follow her directions. The nurse explains this is normal for his age, as negativism is attempting to meet which developmental need?

• A. Trust
• B. Initiative
• C. Independence
• D. Self-esteem

Correct answer: C

Rationale: In Erikson's theory of development, toddlers struggle to assert independence. They often use the word 'no' even when they mean yes. This stage is called autonomy versus shame and doubt. The child's behavior of saying 'no' and resisting directions reflects the developmental need for independence, not trust (option A), initiative (option B), or self-esteem (option D). Trust is typically associated with early infancy, initiative with preschool age, and self-esteem with later childhood and adolescence.

4. A 23-year-old woman is admitted to the infusion clinic after a Multiple Sclerosis exacerbation. The physician orders methylprednisolone infusions (Solu-Medrol). The nurse would expect which of the following outcomes after administration of this medication?

• A. A decrease in muscle spasticity and involuntary movements
• B. A slowed progression of Multiple Sclerosis-related plaques
• C. A decrease in the length of the exacerbation
• D. A stabilization of mood and sleep

Correct answer: C

Rationale: Methylprednisolone infusion is the first-line treatment during an acute exacerbation of Multiple Sclerosis. It is used to decrease the length and severity of a relapse by reducing inflammation in the central nervous system. Choice A, 'A decrease in muscle spasticity and involuntary movements,' is incorrect because methylprednisolone primarily targets inflammation and does not directly address muscle spasticity. Choice B, 'A slowed progression of Multiple Sclerosis-related plaques,' is incorrect as methylprednisolone is not used to slow the progression of the disease but rather to manage acute exacerbations. Choice D, 'A stabilization of mood and sleep,' is not an expected outcome of methylprednisolone administration for Multiple Sclerosis exacerbation as it primarily targets the inflammatory process associated with the relapse.

5. After hydrostatic reduction for intussusception, what client response should the nurse expect to observe?

• A. Abdominal distension
• B. Currant jelly-like stools
• C. Severe, colicky-type pain with vomiting
• D. Passage of barium or water-soluble contrast with stools

Correct answer: D

Rationale: After hydrostatic reduction for intussusception, the nurse should observe the passage of barium or water-soluble contrast with stools. This indicates a successful reduction of the telescoped bowel segment. Abdominal distension and currant jelly-like stools are clinical manifestations of intussusception, not expected outcomes following hydrostatic reduction. Severe, colicky-type pain with vomiting suggests an unresolved gastrointestinal issue, not a successful reduction of intussusception.
