Nursing Elites

1. A nurse is caring for a client who is taking digoxin. Which of the following findings should the nurse identify as a sign of digoxin toxicity?

• A. Bradycardia
• B. Tachycardia
• C. Hypotension
• D. Hyperkalemia

Correct answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxicity manifesting as bradycardia due to its effect on the heart's electrical conduction system. Tachycardia (choice B) is not typically associated with digoxin toxicity. Hypotension (choice C) and hyperkalemia (choice D) are not direct signs of digoxin toxicity. Therefore, the correct answer is bradycardia.

2. A nurse is caring for a client who has a serum sodium level of 125 mEq/L. Which of the following findings should the nurse expect?

• A. Numbness of the extremities.
• B. Abdominal cramping.
• C. Bradycardia.
• D. Positive Chvostek's sign.

Correct answer: B

Rationale: Abdominal cramping is a common manifestation of hyponatremia, as the sodium imbalance affects muscle function. Numbness of the extremities (Choice A) is more commonly associated with electrolyte imbalances such as hypocalcemia. Bradycardia (Choice C) is not typically a direct manifestation of hyponatremia. Positive Chvostek's sign (Choice D) is related to hypocalcemia, not hyponatremia.

3. What are the signs and symptoms of hyperkalemia and how should it be managed?

• A. Muscle weakness and cardiac arrhythmias; administer calcium gluconate
• B. Confusion and bradycardia; administer insulin and glucose
• C. Fatigue and irregular heart rate; administer diuretics
• D. Nausea and vomiting; administer sodium bicarbonate

Correct answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

4. A charge nurse is discussing the responsibility of nurses caring for clients who have C. difficile. Which of the following information should the nurse include in the teaching?

• A. Assign the client to a room with a negative air-flow system
• B. Use alcohol-based hand sanitizer when leaving the client's room
• C. Clean contaminated surfaces in the client's room with a phenol solution
• D. Have family members wear a gown and gloves when visiting

Correct answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting clients with C. difficile is crucial to prevent the transmission of the infection. Options A, B, and C are incorrect because assigning the client to a room with a negative air-flow system, using alcohol-based hand sanitizer, and cleaning contaminated surfaces with a phenol solution are not specific measures for preventing the spread of C. difficile.

5. A nurse is caring for a client who has severe preeclampsia and is receiving magnesium sulfate intravenously. The nurse discontinues the magnesium sulfate after the client displays toxicity. Which of the following actions should the nurse take?

• A. Position the client supine.
• B. Prepare an IV bolus of dextrose 5% in water.
• C. Administer methylergonovine IM.
• D. Administer calcium gluconate IV.

Correct answer: D

Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote that should be administered promptly. Positioning the client supine (Choice A) is not the priority in this scenario. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Methylergonovine IM (Choice C) is used for postpartum hemorrhage, not for magnesium sulfate toxicity.
