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 patient presents with vesicles covering the upper torso. Which of the following situations could cause this condition?

• A. Knife fight
• B. Auto accident
• C. Sunburn
• D. Fungal infection

Correct answer: C

Rationale: Vesicles are fluid-filled blisters. In the context of the upper torso, the presentation of vesicles suggests a second-degree sunburn. Sunburn can cause blistering, leading to the formation of vesicles. Choice A, 'Knife fight,' does not align with the presentation of vesicles on the upper torso due to trauma. Choice B, 'Auto accident,' is more likely to cause abrasions or bruises rather than vesicles. Choice D, 'Fungal infection,' typically presents with other symptoms such as redness, itching, or scaling, but not vesicles on the upper torso.

3. A patient with a pleural effusion is scheduled for a thoracentesis. Which action should the nurse take to prepare the patient for the procedure?

• A. Start a peripheral IV line to administer any necessary sedative drugs.
• B. Position the patient sitting upright on the edge of the bed and leaning forward.
• C. Obtain a collection device to hold a reasonable amount of pleural fluid for extraction.
• D. Remove the water pitcher and remind the patient not to eat or drink anything for 6 hours.

Correct answer: B

Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.

4. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

5. Which of the following is TRUE about shock?

• A. A patient with severe shock does not always have an abnormally low blood pressure.
• B. Confusion and deteriorating mentation are indicative of hypotensive shock.
• C. Patients with compensated shock may not be able to maintain a normal blood pressure.
• D. A normal blood pressure does not imply that the patient is stable.

Correct answer: B

Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.
