Nursing Elites

1. The nurse is caring for a patient whose serum sodium level is 140 mEq/L and serum potassium level is 5.4 mEq/L. The nurse will contact the patient’s provider to discuss an order for

• A. a low-potassium diet.
• B. intravenous sodium bicarbonate.
• C. Kayexalate and sorbitol.
• D. salt substitutes.

Correct answer: A

Rationale: In the scenario presented, the patient is experiencing mild hyperkalemia with a potassium level of 5.4 mEq/L. The appropriate intervention for mild hyperkalemia is a low-potassium diet to restrict potassium intake. This helps in managing and preventing further elevation of potassium levels. Intravenous sodium bicarbonate is not indicated as the patient's sodium level is normal at 140 mEq/L. Kayexalate, a cation-exchange resin, is typically used for severe hyperkalemia to promote potassium excretion. Salt substitutes, which often contain potassium chloride, should be avoided in patients with hyperkalemia as they can exacerbate the condition by increasing potassium levels further.

2. The healthcare provider is caring for a patient who is receiving an intravenous antibiotic. The patient has a serum drug trough of 1.5 mcg/mL. The normal trough for this drug is 1.7 mcg/mL to 2.2 mcg/mL. What will the healthcare provider expect the patient to experience?

• A. Inadequate drug effects
• B. Increased risk of superinfection
• C. Minimal adverse effects
• D. Slowed onset of action

Correct answer: A

Rationale: A serum drug trough level below the normal range (1.7 mcg/mL to 2.2 mcg/mL) indicates that the medication concentration is insufficient to provide therapeutic effects, leading to inadequate drug effects. A low trough level does not directly correlate with an increased risk of superinfection, minimal adverse effects, or a slowed onset of action, as these are more related to the drug's concentration within the therapeutic range.

3. Upon arrival of a client transferred to the surgical unit, what should the nurse plan to do first?

• A. Assess the patency of the airway
• B. Check tubes and drains for patency
• C. Check the dressing for bleeding
• D. Assess the vital signs to compare them with preoperative measurements

Correct answer: A

Rationale: The initial action for the nurse upon the arrival of a client to the surgical unit is to assess the patency of the airway. This step takes priority to ensure that the client has a clear airway for adequate breathing. Checking tubes and drains for patency, inspecting the dressing for bleeding, and assessing vital signs to compare with preoperative measurements are important subsequent steps in the assessment process. However, ensuring the airway is patent is the immediate priority to maintain the client's respiratory function and overall well-being.

4. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?

• A. Facial flushing.
• B. Fever.
• C. Pounding headache.
• D. Feelings of dizziness.

Correct answer: D

Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.

5. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?

• A. Calcium and magnesium
• B. Sodium and calcium
• C. Potassium and chloride
• D. Potassium and magnesium

Correct answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.
