Nursing Elites

1. A patient is admitted to the emergency department with severe fatigue and confusion. Laboratory studies are done. Which laboratory value will require the most immediate action by the nurse?

• A. Arterial blood pH is 7.32.
• B. Serum calcium is 18 mg/dL.
• C. Serum potassium is 5.1 mEq/L
• D. Arterial oxygen saturation is 91%.

Correct answer: B

Rationale: The correct answer is B. A serum calcium level of 18 mg/dL is significantly elevated, posing a high risk for cardiac dysrhythmias. Immediate action is required to initiate cardiac monitoring and notify the healthcare provider. While the abnormalities in arterial blood pH, serum potassium, and arterial oxygen saturation also need attention, they are not as immediately life-threatening as the critically high serum calcium level. Therefore, addressing the serum calcium level takes precedence in this scenario.

2. 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.

3. 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.

4. The nurse observes an unlicensed assistive personnel (UAP) who is providing a total bed bath for a confused and lethargic client. The UAP is soaking the client's foot in a basin of warm water placed on the bed. What action should the nurse take?

• A. Remove the basin of water from the client's bed immediately
• B. Remind the UAP to dry between the client's toes completely
• C. Advise the UAP that this procedure is damaging to the skin
• D. Add skin cream to the basin of water while the foot is soaking

Correct answer: B

Rationale: Choice (B) is the correct action for the nurse to take in this situation. Ensuring that the UAP dries between the client's toes completely is crucial to prevent skin breakdown due to excessive moisture. While keeping the client's feet clean is important, maintaining dryness is paramount for skin integrity. Choices (A), (C), and (D) are incorrect: (A) removing the basin of water immediately may disrupt the care process without addressing the root issue, (C) advising the UAP that the procedure is damaging to the skin is not as immediate or specific to the observed problem, and (D) adding skin cream to the water may not address the need for drying the client's toes thoroughly.

5. 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.
