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 is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?

• A. Chest x-ray shows no upper lobe infiltrates.
• B. TB medications have been taken for 6 months.
• C. Mantoux testing shows an induration of 10 mm.
• D. Three sputum smears for acid-fast bacilli are negative.

Correct answer: D

Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.

3. The home health nurse visits a male client to provide wound care and finds the client lethargic and confused. His wife states he fell down the stairs two (2) hours ago. The nurse should

• A. Place a call to the client's healthcare provider for instructions
• B. Send him to the emergency room for evaluation
• C. Reassure the client's wife that the symptoms are transient
• D. Instruct the client's wife to call the doctor if his symptoms become worse

Correct answer: B

Rationale: In this scenario, the client is presenting with concerning symptoms of lethargy and confusion after a fall. These symptoms could indicate a serious underlying issue, such as a head injury or internal bleeding. The nurse's priority is to ensure the client receives immediate evaluation and treatment to prevent any further harm. Option B is the correct choice as it emphasizes the urgency of the situation. Choices A, C, and D are incorrect because they do not address the critical nature of the client's condition. Contacting the healthcare provider, reassuring the wife, or waiting for symptoms to worsen could delay necessary medical intervention.

4. The nurse is preparing to care for an infant who has esophageal atresia with tracheoesophageal fistula. Surgery is scheduled to be performed in 1 hour. Intravenous fluids have been initiated, and a nasogastric (NG) tube has been inserted by the primary healthcare provider. The nurse plans care, knowing that which intervention is of highest priority during this preoperative period?

• A. Monitor the temperature.
• B. Monitor the blood pressure.
• C. Reposition the infant frequently.
• D. Aspirate the NG tube every 5 to 10 minutes.

Correct answer: D

Rationale: Esophageal atresia with tracheoesophageal fistula is a critical neonatal surgical emergency. The highest priority intervention during the preoperative period is to aspirate the NG tube every 5 to 10 minutes to keep the proximal pouch clear of secretions and prevent aspiration. This is crucial in reducing the risk of gastric secretions entering the lungs. Repositioning the infant frequently is not as critical as ensuring the NG tube is aspirated. Monitoring the temperature and blood pressure are important nursing interventions but are not the highest priority in this situation. It is essential to prioritize airway protection and prevent aspiration in this neonate undergoing urgent surgical intervention.

5. A 15-year-old female who ingested 15 tablets of maximum strength acetaminophen 45 minutes ago is rushed to the emergency department. Which of these orders should the nurse do first?

• A. Gastric lavage
• B. Administer acetylcysteine (Mucomyst) orally
• C. Start an IV Dextrose 5% with 0.33% normal saline to keep the vein open
• D. Have the patient drink activated charcoal mixed with water

Correct answer: A

Rationale: Acetaminophen overdose is extremely toxic to the liver causing hepatotoxicity. Early symptoms of hepatic damage include nausea, vomiting, abdominal pain, and diarrhea. If not treated immediately, hepatic necrosis occurs and may lead to death. Removing as much of the drug as possible is the first step in treatment for acetaminophen overdose, this is best done through gastric lavage. Gastric lavage (irrigation) and aspiration consist of flushing the stomach with fluids and then aspirating the fluid back out. This procedure is done in life-threatening cases such as acetaminophen toxicity and only if less than one (1) hour has occurred after ingestion.
