Nursing Elites

1. The nurse notes a serum calcium level of 7.9 mg/dL for a patient who has chronic malnutrition. Which action should the nurse take next?

• A. Monitor ionized calcium level.
• B. Give oral calcium citrate tablets.
• C. Check parathyroid hormone level.
• D. Administer vitamin D supplements.

Correct answer: A

Rationale: This patient with chronic malnutrition is likely to have a low serum albumin level, which will affect the total serum calcium. A more accurate reflection of calcium balance is the ionized calcium level. Most of the calcium in the blood is bound to protein (primarily albumin). Alterations in serum albumin levels affect the interpretation of total calcium levels. Low albumin levels result in a drop in the total calcium level, although the level of ionized calcium is not affected. The nurse should monitor the ionized calcium level to get a clearer picture of the patient's calcium status. Giving oral calcium citrate tablets, checking parathyroid hormone level, or administering vitamin D supplements may be necessary based on the ionized calcium results, but they are not the immediate next step in assessment and management.

2. 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.

3. A patient who has small cell carcinoma of the lung develops syndrome of inappropriate antidiuretic hormone (SIADH). The nurse should notify the healthcare provider about which assessment finding?

• A. Reported weight gain
• B. Serum hematocrit of 42%
• C. Serum sodium level of 120 mEq/L
• D. Total urinary output of 280 mL during the past 8 hours

Correct answer: C

Rationale: The correct answer is C, a serum sodium level of 120 mEq/L. Hyponatremia is the most important finding to report in SIADH. SIADH causes water retention and a decrease in serum sodium levels. Hyponatremia can lead to confusion and other central nervous system effects and requires treatment. Adequate kidney function is indicated by a urinary output of at least 30 mL/hr. A hematocrit level of 42% is normal. Weight gain is expected due to water retention in SIADH.

4. A 54-year-old male client and his wife were informed this morning that he has terminal cancer. Which nursing intervention is likely to be most beneficial?

• A. Ask the wife how she would like to participate in the client's care
• B. Provide the wife with information about hospice
• C. Encourage the wife to visit after painful treatments are completed
• D. Refer the wife to a support group for family members of those dying of cancer

Correct answer: A

Rationale: The most beneficial nursing intervention in this situation is to ask the wife how she would like to participate in the client's care. Involving the spouse in the care of the terminally ill client can provide comfort, support, and a sense of contribution during a challenging time. Providing information about hospice (B) is important but may not be the immediate priority. Encouraging the wife to visit after treatments are completed (C) may delay her involvement in the care. Referring her to a support group (D) is a good idea but might be more suitable at a later stage.

5. 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.
