Nursing Elites

1. 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.

2. 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.

3. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?

• A. Administer 30 Units of Lantus Daily
• B. CT of the spine with contrast
• C. X-ray of the abdomen and chest
• D. Administer heparin subcutaneously 5,000 Units every 12 hours

Correct answer: B

Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.

4. The infection control nurse is assigned to a patient with osteomyelitis related to a heel ulcer. The wound is 5cm in diameter and the drainage saturates the dressing so that it must be changed every hour. What is her priority intervention?

• A. Place the patient under contact precautions
• B. Use strict aseptic technique when caring for the wound
• C. Place another dressing to reinforce the first one
• D. Elevate the patient's leg to prevent more drainage

Correct answer: A

Rationale: The priority intervention for a patient with osteomyelitis related to a heel ulcer, with a wound that saturates the dressing every hour, is to place the patient under contact precautions. Contact precautions are essential when managing infectious wounds to prevent the spread of infection to healthcare workers, other patients, and visitors. Strict aseptic technique (Choice B) should always be used with wound care but is secondary to implementing contact precautions in this scenario. Placing another dressing (Choice C) or elevating the patient's leg (Choice D) may be necessary but do not address the immediate need for infection control measures.

5. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.
