1. What are the key signs of hyperkalemia and how should it be treated?

A. Elevated potassium levels, muscle weakness; administer calcium gluconate
B. Decreased potassium levels, confusion; administer potassium chloride
C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
D. Low sodium levels, muscle cramps; administer sodium chloride

Correct answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

2. How should a healthcare professional manage a patient with suspected infection?

A. Monitor vital signs and administer antibiotics
B. Check for fever and monitor white blood cell count
C. Assess for pain and check for localized swelling
D. Monitor for chills and administer fluids

Correct answer: A

Rationale: Correct answer: When managing a patient with suspected infection, it is crucial to monitor vital signs like temperature, heart rate, blood pressure, and respiratory rate to assess the severity of the infection. Administering antibiotics is also essential to treat the infection. Choice B is incorrect because while checking for fever and monitoring white blood cell count are important, they alone are not sufficient to manage the patient. Choice C focuses on assessing pain and localized swelling, which are important but not primary in managing suspected infection. Choice D mentions monitoring for chills and administering fluids, which are not the primary interventions for managing a suspected infection.

3. A nurse is teaching a client who has multiple sclerosis (MS) about strategies to reduce fatigue. Which of the following instructions should the nurse include?

A. Exercise to the point of exhaustion
B. Rest as needed throughout the day
C. Avoid physical activity
D. Exercise only once per week

Correct answer: B

Rationale: The correct instruction the nurse should include is to 'Rest as needed throughout the day.' Fatigue is a common symptom of multiple sclerosis (MS), and adequate rest is essential to manage it effectively. Resting as needed helps conserve energy and prevent fatigue from worsening. Choices A, C, and D are incorrect. 'Exercise to the point of exhaustion' is not recommended as it can lead to increased fatigue. 'Avoiding physical activity' entirely is not advisable as appropriate exercise can help maintain strength and energy levels. 'Exercising only once per week' may not be sufficient to combat fatigue and maintain overall well-being in clients with MS.

4. A nurse is reinforcing teaching about using a cane with a client who has left-leg weakness. What instruction should the nurse give?

A. Use the cane on the weaker side
B. Advance the cane and the strong leg together
C. Maintain two points of support on the floor at all times
D. Advance the cane 30 to 45 cm with each step

Correct answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

5. What are the early signs of hypoglycemia in a diabetic patient?

A. Sweating and trembling
B. Confusion and irritability
C. Dizziness and increased heart rate
D. Nausea and vomiting

Correct answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.
