Nursing Elites

1. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

2. A nurse admits a 3-week-old infant to the special care nursery with a diagnosis of bronchopulmonary dysplasia. As the nurse reviews the birth history, which data would be most consistent with this diagnosis?

• A. Gestational age assessment suggested growth retardation
• B. Meconium was cleared from the airway at delivery
• C. Phototherapy was used to treat Rh incompatibility
• D. The infant received mechanical ventilation for 2 weeks

Correct answer: D

Rationale: The correct answer is 'The infant received mechanical ventilation for 2 weeks.' Bronchopulmonary dysplasia is a condition primarily caused by therapies like positive-pressure ventilation used in the treatment of lung disease. This leads to lung damage and subsequent respiratory problems. Choices A, B, and C are not consistent with the diagnosis of bronchopulmonary dysplasia. Gestational age assessment suggesting growth retardation is more indicative of intrauterine growth restriction, clearing meconium from the airway at delivery is related to potential respiratory issues at birth, and phototherapy for Rh incompatibility is unrelated to bronchopulmonary dysplasia.

3. What should the nurse in the emergency department do first for a new patient who is vomiting blood?

• A. Insert a large-gauge IV catheter.
• B. Draw blood for coagulation studies.
• C. Check blood pressure (BP), heart rate, and respirations.
• D. Place the patient in the supine position.

Correct answer: C

Rationale: The nurse's initial action should focus on assessing the patient's hemodynamic status by checking vital signs like blood pressure, heart rate, and respirations. This assessment will help determine the patient's immediate needs and guide further interventions. Drawing blood for coagulation studies and inserting an IV catheter are important steps, but they can follow the initial assessment of vital signs. Placing the patient in the supine position can be risky without first assessing the patient's vital signs, as aspiration is a concern. Therefore, assessing vital signs is the priority to ensure appropriate and timely care for the patient.

4. Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?

• A. A client who is 9 weeks pregnant
• B. A client with a femur fracture
• C. A morbidly obese client
• D. A client with hypertension

Correct answer: C

Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended. Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns. Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure. Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.

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

• A. Manage secretions by providing suction on a regular basis
• B. Cleanse the site daily with a mixture of povidone-iodine and water
• C. Avoid using tube ties to secure the tube
• D. None of the above

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.
