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. Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?

• A. Tie the knot with a double turn or square knot
• B. Ensure that the restraints are snug against the client's wrists
• C. Ensure that the knot can be quickly released
• D. Move the ties so the restraints are secured to the side rails

Correct answer: C

Rationale: The priority is to ensure that the knot can be quickly released to allow for quick intervention if necessary. Tying the knot with a double turn or square knot (Choice A) may make it more difficult to release quickly in an emergency. Ensuring that the restraints are snug against the client's wrists (Choice B) may compromise circulation and cause discomfort. Moving the ties to secure the restraints to the side rails (Choice D) is not the appropriate action as it can limit the client's movement and access to care.

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 home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give to this patient related to fluid intake?

• A. Increase fluids if your mouth feels dry.
• B. More fluids are needed if you feel thirsty.
• C. Drink more fluids in the late evening hours.
• D. If you feel lethargic or confused, you need more to drink.

Correct answer: A

Rationale: The correct answer is A. An alert, older patient can self-assess for signs of dehydration like dry mouth. This instruction is appropriate as it encourages the patient to respond to early signs of dehydration. Choice B is incorrect because the thirst mechanism decreases with age and feeling thirsty may not accurately indicate the need for fluids. Choice C is incorrect as many older patients prefer to limit evening fluid intake to enhance sleep quality. Choice D is incorrect because an older adult who is lethargic or confused may not be able to accurately assess their need for fluids.

5. IV potassium chloride (KCl) 60 mEq is prescribed for the treatment of a patient with severe hypokalemia. Which action should the nurse take?

• A. Administer the KCl as a rapid IV bolus.
• B. Infuse the KCl at a rate of 10 mEq/hour.
• C. Only give the KCl through a central venous line.
• D. Discontinue cardiac monitoring during the infusion.

Correct answer: B

Rationale: The correct action for the nurse to take is to infuse the KCl at a rate of 10 mEq/hour. Rapid IV infusion of KCl can lead to cardiac arrest due to its potential for causing hyperkalemia. While KCl can be administered through peripheral veins, central venous lines are not necessary unless specified. It is crucial to continue cardiac monitoring during potassium infusion to promptly identify and manage any potential dysrhythmias that may occur.
