Nursing Elites

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 nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?

• A. Slow pulse rate
• B. Weight gain
• C. Decreased systolic pressure
• D. Irregular WBC lab values

Correct answer: B

Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.

3. A victim of domestic violence states, 'If I were better, I would not have been beaten.' Which feeling best describes what the victim may be experiencing?

• A. Fear
• B. Helplessness
• C. Self-blame
• D. Rejection

Correct answer: C

Rationale: The correct answer is self-blame. In this scenario, the victim is attributing the abuse to their own inadequacies or faults, thinking that if they were different, the abuse would not occur. This is a common response seen in victims of domestic violence, where they wrongly internalize the blame for the abuser's actions. Fear (Choice A) is a valid emotion, but in this case, the victim is not expressing fear but rather self-blame. Helplessness (Choice B) is also a common feeling in victims of domestic violence, but in this specific statement, the victim is demonstrating self-blame. Rejection (Choice D) does not accurately reflect the victim's statement and emotional response in the given scenario.

4. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?

• A. Increasing heart rate above normal for the patient's age.
• B. Absent peripheral pulses
• C. Decreasing level of consciousness
• D. Increasing blood pressure

Correct answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.

5. Following surgery to correct cryptorchidism, what is the priority action that the nurse should include in the plan of care?

• A. Prevent tension on the suture.
• B. Monitor urine for glucose and acetone.
• C. Encourage oral fluids, and monitor intake and output.
• D. Encourage coughing and deep breathing every hour.

Correct answer: A

Rationale: The correct answer is to prevent tension on the suture. After surgery for cryptorchidism, the testicle is held in position by an internal suture that should not be dislodged. Immobilization of the area for a week is crucial to prevent complications like bleeding and infection. Monitoring urine for glucose and acetone is unrelated to this surgery. While maintaining hydration is important, forcing fluids is not necessary. Encouraging coughing and deep breathing every hour may be a postoperative consideration, but it is not the priority for this specific surgery.
