Nursing Elites

1. 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.

2. A client is seen for testing to rule out Rocky Mountain Spotted Fever. Which of the following signs or symptoms is associated with this condition?

• A. Fever and rash
• B. Circumoral cyanosis
• C. Elevated glucose levels
• D. All of the above

Correct answer: A

Rationale: The correct answer is 'Fever and rash.' Rocky Mountain Spotted Fever (RMSP) is caused by the R. rickettsii pathogen, which damages blood vessels. Patients with RMSP typically present with fever, edema, and a rash that initially appears on the hands and feet before spreading across the body. The disease manifests following a tick bite. Choice A is correct as fever and rash are key indicators of RMSP. Circumoral cyanosis (choice B) is not typically associated with RMSP; it refers to a bluish discoloration around the mouth and is more indicative of oxygen deprivation. Elevated glucose levels (choice C) are not specific signs of RMSP. Therefore, choice D, 'All of the above,' is incorrect since only choice A, 'Fever and rash,' is associated with Rocky Mountain Spotted Fever.

3. How does shock typically progress?

• A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
• B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
• C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
• D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

4. 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.

5. Signs and symptoms of stroke may include all of the following EXCEPT:

• A. Sudden weakness or numbness of the face, arm, or leg.
• B. Sudden confusion.
• C. Sudden headache with no known cause.
• D. Hypotension.

Correct answer: D

Rationale: Hypotension is not a typical sign or symptom of an acute stroke. The correct signs and symptoms of a stroke include sudden weakness or numbness of the face, arm, or leg, sudden confusion, and a sudden headache with no known cause. Hypotension, which refers to low blood pressure, is not a common indicator of a stroke. It is important to differentiate between hypotension and hypertension in the context of stroke symptoms, as hypertension (high blood pressure) is actually a risk factor for strokes. Sudden weakness, numbness, confusion, and headache are signs associated with a stroke due to a disruption in blood flow to the brain. Hypotension, on the other hand, primarily indicates low blood pressure and is not directly linked to the typical presentation of a stroke.
