Nursing Elites

1. A patient is admitted for hypovolemia associated with multiple draining wounds. Which assessment would be the most accurate way for the nurse to evaluate fluid balance?

• A. Skin turgor
• B. Daily weight
• C. Presence of edema
• D. Hourly urine output

Correct answer: B

Rationale: Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age and can be affected by various factors other than fluid balance. Presence of edema indicates excess fluid has moved into the interstitial space, which may not always be directly correlated with overall fluid balance. Hourly urine outputs, though important, do not provide a comprehensive picture of fluid balance as they do not consider fluid intake, insensible losses, or other sources of fluid loss.

2. A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?

• A. blood transfusion
• B. chemotherapy
• C. bone marrow transplantation
• D. immunosuppressive therapy

Correct answer: C

Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.

3. A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is most appropriate?

• A. There is a decreased risk for infection when 25% dextrose is infused through a central line.
• B. The prescribed infusion can be given much more rapidly when the patient has a central line.
• C. The 25% dextrose is hypertonic and will be more rapidly diluted when given through a central line.
• D. The required blood glucose monitoring is more accurate when samples are obtained from a central line.

Correct answer: C

Rationale: The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.

4. A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?

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

Correct answer: A

Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.

5. Following a thyroidectomy, a patient complains of “a tingling feeling around my mouth.” Which assessment should the nurse complete immediately?

• A. Presence of the Chvostek’s sign
• B. Abnormal serum potassium level
• C. Decreased thyroid hormone level
• D. Bleeding on the patient’s dressing

Correct answer: A

Rationale: The correct assessment the nurse should complete immediately is checking for the presence of the Chvostek’s sign. The patient's complaint of tingling around the mouth is indicative of hypocalcemia, which can result from parathyroid injury/removal during thyroidectomy. The Chvostek’s sign is a clinical indication of hypocalcemia, where facial muscle twitching occurs when the facial nerve is tapped. Assessing serum potassium levels (choice B) is not the priority in this situation. While thyroid hormone levels (choice C) play a role in overall health, they do not directly relate to the patient’s current symptoms. Checking for bleeding on the dressing (choice D) is important but not the immediate priority when addressing potential hypocalcemia.
