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. A client with an NG tube is experiencing nausea and a decrease in gastric secretions. What should the nurse do first?

A. Position the client on their left side
B. Irrigate the NG tube with sterile water
C. Replace the NG tube with a new one
D. Increase the suction setting to relieve the blockage

Correct answer: B

Rationale: The correct first action for a client with an NG tube experiencing nausea and decreased gastric secretions is to irrigate the NG tube with sterile water. This can help clear any blockages in the tube, which may be causing the symptoms. Positioning the client on their left side may be helpful for enteral feedings but is not the priority in this situation. Replacing the NG tube should not be the initial step unless irrigation fails to resolve the issue. Increasing the suction setting without attempting to clear the blockage can be harmful to the client.

3. A client is undergoing radiation therapy. Which of the following actions should the nurse take to prevent skin irritation?

A. Apply heat packs to the area
B. Use perfumed soap to cleanse the area
C. Keep the area moist with lotion
D. Avoid sun exposure to the treated area

Correct answer: D

Rationale: Avoiding sun exposure is crucial to prevent skin irritation and burns in clients undergoing radiation therapy. Radiation therapy makes the skin more sensitive to sunlight, increasing the risk of skin damage. Applying heat packs (choice A) can exacerbate skin irritation as heat can further irritate the skin that is already sensitive due to radiation. Using perfumed soap (choice B) can further irritate the skin due to its harsh chemicals, potentially worsening skin reactions. While keeping the area moist with lotion (choice C) may seem beneficial, some lotions contain ingredients that can worsen skin reactions during radiation therapy. Therefore, avoiding sun exposure to the treated area (choice D) is the most appropriate action to prevent skin irritation and damage during radiation therapy.

4. When should a healthcare provider suction a client's tracheostomy?

A. When the client is hypotensive
B. When the client is irritable
C. When the client is flushed
D. When the client is bradycardic

Correct answer: B

Rationale: Irritability is an early sign that suctioning is required to clear secretions in a client with a tracheostomy. Hypotension, flushing, and bradycardia are not direct indicators for suctioning a tracheostomy. Hypotension may indicate a need for fluid resuscitation or other interventions, flushing could be due to various reasons like fever, and bradycardia may require evaluation for cardiac causes.

5. A nurse is caring for a client who is in Buck's traction. Which of the following actions should the nurse take?

A. Remove the weights
B. Ensure the weights hang freely
C. Increase the traction force
D. Loosen the ropes

Correct answer: B

Rationale: The correct action the nurse should take when caring for a client in Buck's traction is to ensure the weights hang freely. This is essential to maintain proper alignment and ensure the effectiveness of Buck's traction. Removing the weights (Choice A) would be incorrect and could compromise the treatment. Increasing the traction force (Choice C) can lead to excessive pressure and potential harm to the client. Loosening the ropes (Choice D) would also be inappropriate as it can disrupt the traction's effectiveness and alignment.
