1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

2. The nurse provides home care instructions to the parents of a child with celiac disease. The nurse should teach the parents to include which food item in the child's diet?

Correct answer: A

Rationale: In celiac disease, individuals are intolerant to gluten found in wheat, barley, rye, and oats. Therefore, it is crucial to eliminate these grains from the diet. Rice, corn, or millet are safe alternatives for individuals with celiac disease. Oatmeal is generally avoided unless specifically labeled as gluten-free due to possible cross-contamination. Rye toast and white bread contain gluten and should be avoided in celiac disease. Vitamin supplements may also be necessary to address deficiencies caused by dietary restrictions.

3. A healthcare provider calls a physician with the concern that a patient has developed a pulmonary embolism. Which of the following symptoms has the healthcare provider most likely observed?

Correct answer: B

Rationale: The correct answer is 'The patient suddenly complains of chest pain and shortness of breath.' Typical symptoms of pulmonary embolism include chest pain, shortness of breath, and severe anxiety. The physician should be notified immediately. Clinical signs and symptoms for pulmonary embolism are nonspecific; therefore, patients suspected of having pulmonary embolism"?because of unexplained dyspnea, tachypnea, or chest pain or the presence of risk factors for pulmonary embolism"?must undergo diagnostic tests until the diagnosis is ascertained or eliminated or an alternative diagnosis is confirmed. Choices A, C, and D describe symptoms that are not typically associated with a pulmonary embolism, making them incorrect.

4. One hour after a thoracotomy, a patient complains of incisional pain at a level 7 (based on a 0 to 10 scale) and has decreased left-sided breath sounds. The pleural drainage system has 100 mL of bloody drainage and a large air leak. Which action is best for the nurse to take next?

Correct answer: S

Rationale: In this scenario, the best action is to set up the patient-controlled analgesia (PCA) and administer the loading dose of morphine. The patient's pain level is high, which can hinder deep breathing and coughing. Addressing pain control is a priority to facilitate optimal respiratory function. Milking the chest tube to remove clots is unnecessary as the drainage amount is not alarming in the early postoperative period. Clamping the chest tube to locate the air leak is not recommended as it can lead to tension pneumothorax. Assisting the patient to deep breathe, cough, and use the incentive spirometer is important but should follow adequate pain management to ensure the patient can effectively participate in these activities.

5. Which of the following techniques can help to prevent skin irritation or breakdown around a tracheostomy site?

Correct answer: A

Rationale: Excess secretions from the tracheostomy tube can collect near the stomal opening and cause skin breakdown. Management of secretions through regular suctioning will keep the area clean and dry, minimizing skin irritation. Choice B, cleansing the site daily with povidone-iodine and water, is incorrect as it may lead to skin irritation due to the harshness of povidone-iodine. Choice C, avoiding tube ties to secure the tube, is also incorrect as securing the tube is essential for stability. Choice D, 'None of the above,' is incorrect as managing secretions through suctioning is crucial in preventing skin irritation.
