Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?

• A. Restrict fluids as prescribed.
• B. Care for the arteriovenous fistula.
• C. Encourage foods high in potassium.
• D. Administer analgesics as prescribed.

Correct answer: A

Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.

3. A patient has been taking mood stabilizing medication but is afraid of needles. They ask the nurse what medication would NOT require regular lab testing. What is the nurse's best response?

• A. Valproic Acid (Depakote)
• B. Clozapine (Clozaril)
• C. Lithium
• D. Risperidone (Risperdal)

Correct answer: D

Rationale: The correct answer is Risperidone (Risperdal) because it is the only medication among the options that does not require regular lab testing. Risperidone is not associated with the need for routine blood draws to monitor medication levels or potential side effects. Choices A, B, and C (Valproic Acid, Clozapine, Lithium) are all known to require frequent lab monitoring due to various reasons such as potential toxicity, therapeutic drug levels, or adverse effects on certain organ functions. Therefore, considering the patient's fear of needles and the desire to avoid frequent blood tests, Risperidone would be the most suitable option.

4. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?

• A. Slow pulse rate
• B. Weight gain
• C. Decreased systolic pressure
• D. Irregular WBC lab values

Correct answer: B

Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.

5. You have accompanied the physician into the family waiting room to tell a young husband that his wife has not survived the car accident she was in. The husband is crying and distraught. What is the most appropriate approach to supporting this family member?

• A. Ask if he would like to donate his wife's organs
• B. Sit quietly with him
• C. Ask about funeral arrangements
• D. Consult social services

Correct answer: B

Rationale: The most caring and supportive approach in a time of extreme distress is usually to sit quietly with the distressed individual until they have had the opportunity to absorb the news and gather themselves. Providing a supportive presence is often the most valuable tool a caregiver can use when circumstances bring overwhelming emotional pain to those they are caring for. Asking about organ donation at this moment may come off as insensitive and should not be a priority. Inquiring about funeral arrangements and consulting social services can be addressed later, once the husband has had time to process the initial shock and emotions.
