Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. The nurse is caring for a patient who is receiving isotonic intravenous (IV) fluids at an infusion rate of 125 mL/hour. The nurse performs an assessment and notes a heart rate of 102 beats per minute, a blood pressure of 160/85 mm Hg, and crackles auscultated in both lungs. Which action will the nurse take?

• A. Decrease the IV fluid rate and notify the provider.
• B. Increase the IV fluid rate and notify the provider.
• C. Request an order for a colloidal IV solution.
• D. Request an order for a hypertonic IV solution.

Correct answer: A

Rationale: The patient is showing signs of fluid volume excess, indicated by crackles in both lungs, increased heart rate, and elevated blood pressure. To address this, the nurse should decrease the IV fluid rate and notify the provider. Increasing the IV fluid rate would worsen fluid overload. Requesting colloidal or hypertonic IV solutions would exacerbate the issue by pulling more fluids into the intravascular space, leading to further volume overload.

3. A nurse teaches a client who is recovering from a nephrectomy secondary to kidney trauma. Which statement should the nurse include in this client’s teaching?

• A. Since you only have one kidney, a salt and fluid restriction is required.
• B. Your therapy will include hemodialysis while you recover.
• C. Medication will be prescribed to control your high blood pressure.
• D. You need to avoid participating in contact sports like football.

Correct answer: D

Rationale: Clients with one kidney need to avoid contact sports because the kidneys are easily injured. The client will not be required to restrict salt and fluids, end up on dialysis, or have new hypertension because of the nephrectomy.

4. A client was admitted for a myocardial infarction and cardiogenic shock 2 days ago. Which laboratory test result should a nurse expect to find?

• A. Blood urea nitrogen (BUN) of 52 mg/dL
• B. Creatinine of 2.3 mg/dL
• C. BUN of 10 mg/dL
• D. BUN/creatinine ratio of 8:1

Correct answer: A

Rationale: In cardiogenic shock, decreased renal perfusion leads to an elevated BUN. Choice A is correct. Creatinine remains normal in cardiogenic shock as it signifies kidney damage, which has not occurred in this case. A low BUN indicates overhydration, malnutrition, or liver damage, which are not typically seen in cardiogenic shock. A low BUN/creatinine ratio is associated with fluid volume excess or acute renal tubular acidosis, not specifically indicative of cardiogenic shock.

5. The nurse is caring for a client who is receiving an IV infusion of normal saline and notices that the infusion is not flowing. The insertion site is not inflamed or swollen. What should the nurse do first?

• A. Check the tubing for kinks or obstructions.
• B. Increase the flow rate to improve the infusion.
• C. Reinsert the IV catheter in another vein.
• D. Call the physician for further instructions.

Correct answer: A

Rationale: The correct first action for the nurse to take when an IV infusion is not flowing despite a normal insertion site is to check the tubing for kinks or obstructions. This step is crucial to ensure that there are no preventable issues impeding the flow of the IV solution. Increasing the flow rate without addressing potential obstructions could lead to complications such as infiltration. Reinserting the IV catheter in another vein should only be considered after ruling out tubing issues. Calling the physician for further instructions is not necessary at this stage as troubleshooting the tubing should be the initial intervention.
