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 newly admitted patient is diagnosed with hyponatremia. When making room assignments, the charge nurse should take which action?

• A. Assign the patient to a room near the nurse’s station.
• B. Place the patient in a room nearest to the water fountain.
• C. Place the patient on telemetry to monitor for peaked T waves.
• D. Assign the patient to a semi-private room and place an order for a low-salt diet.

Correct answer: A

Rationale: The correct answer is A. The patient should be placed near the nurse’s station if confused to allow close monitoring by the staff. To help improve serum sodium levels, water intake is restricted, so a patient with hyponatremia should not be placed near a water fountain. Peaked T waves are a sign of hyperkalemia, not hyponatremia, so telemetry for this purpose is unnecessary. Placing a confused patient in a semi-private room could be disruptive to the other patient. Additionally, the patient needs sodium replacement, not a low-salt diet.

3. The nurse is preparing to send a client to the cardiac catheterization lab for an angioplasty. Which client report is most important for the nurse to explore further prior to the procedure?

• A. Experiences facial swelling after eating crab
• B. Reports left chest wall pain prior to the admission
• C. Verbalizes a fear of being in a confined space
• D. Drank a glass of water

Correct answer: A

Rationale: The correct answer is A. Allergy to shellfish can indicate a potential allergy to iodine, which is used in contrast dye for the procedure. This must be explored further to prevent an allergic reaction. Choice B is not directly related to the angioplasty procedure. Choice C pertains to claustrophobia, which can be addressed but is not directly related to the safety of the procedure. Choice D is a routine activity and does not pose a risk to the client during the procedure.

4. 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.

5. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?

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

Correct answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.
