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 a 2-year-old child after corrective surgery for Tetralogy of Fallot. The mother reports that the child has suddenly begun seizing. The nurse recognizes this problem is probably due to

• A. A cerebral vascular accident
• B. Postoperative meningitis
• C. Medication reaction
• D. Metabolic alkalosis

Correct answer: A

Rationale: The correct answer is a cerebral vascular accident. Polycythemia occurs as a physiological reaction to chronic hypoxemia, which commonly occurs in clients with Tetralogy of Fallot. Polycythemia and the resultant increased viscosity of the blood increase the risk of thromboembolic events, including cerebrovascular accidents. Signs and symptoms of a cerebral vascular accident include sudden paralysis, altered speech, extreme irritability or fatigue, and seizures. Postoperative meningitis (choice B) is less likely in this scenario as the sudden onset of seizing is more indicative of a vascular event rather than an infection. Medication reaction (choice C) is not the most probable cause given the history provided. Metabolic alkalosis (choice D) is not associated with sudden seizing in this context.

3. A man is receiving heparin subcutaneously. The patient has dementia and lives at home with a part-time caretaker. The nurse is most concerned about which side effect of heparin?

• A. Back Pain
• B. Fever and Chills
• C. Risk for Bleeding
• D. Dizziness

Correct answer: C

Rationale: The correct answer is 'Risk for Bleeding.' A patient with dementia may have impaired judgment and may be prone to falls or injuries, increasing the risk of bleeding while on heparin therapy. Monitoring for signs of bleeding is crucial in this situation. Choice A, 'Back Pain,' is not a common side effect of heparin. Choice B, 'Fever and Chills,' is not a typical side effect of heparin but may indicate other underlying conditions. Choice D, 'Dizziness,' is not a common side effect of heparin and is not the primary concern in this scenario.

4. A patient is being discharged from the med-surgical unit. The patient has a history of gastritis. The nurse questions the patient on their usual routine at home. Which of these statements would alert the nurse that additional teaching is required?

• A. I avoid NSAIDs. I only take a daily aspirin for my heart health.
• B. I always avoid eating hot and spicy foods.
• C. I will continue taking my antacids with or immediately after meals.
• D. I will only drink coffee once a week, if even that often.

Correct answer: A

Rationale: The correct answer is, 'I avoid NSAIDs. I only take a daily aspirin for my heart health.' Aspirin is classified as an NSAID and can exacerbate existing stomach problems, such as gastritis. Therefore, patients with gastritis should avoid aspirin just like any other NSAID. Choice B, 'I always avoid eating hot and spicy foods,' is a good practice for a patient with gastritis. Choice C, 'I will continue taking my antacids with or immediately after meals,' indicates understanding of the correct timing for antacid use. Choice D, 'I will only drink coffee once a week, if even that often,' shows a suitable limitation of coffee intake, which is beneficial for patients with gastritis.

5. A couple asks the nurse about risks of several birth control methods. What is the most appropriate response by the nurse?

• A. Norplant is safe and can be easily removed.
• B. Oral contraceptives should not be used by smokers.
• C. Depo-Provera is convenient with few side effects.
• D. The IUD provides protection against pregnancy and infection.

Correct answer: B

Rationale: The correct answer is that oral contraceptives should not be used by smokers. The use of oral contraceptives in a woman who smokes increases the risk of cardiovascular problems, such as thromboembolic disorders. This is due to the combined effect of smoking and hormonal contraceptives. Choices A, C, and D are incorrect because they do not address the specific risk associated with smoking and oral contraceptives. Norplant's safety and ease of removal, Depo-Provera's convenience with few side effects, and the IUD's protection against pregnancy and infection are important points but not directly related to the increased risks for smokers using oral contraceptives.
