Nursing Elites

1. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.

2. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

3. After a lumbar puncture, a client reports a severe headache. What is the nurse's priority intervention?

• A. Administer a dose of acetaminophen.
• B. Elevate the head of the bed.
• C. Encourage the client to rest in a dark room.
• D. Administer caffeine to relieve the headache.

Correct answer: B

Rationale: After a lumbar puncture, a severe headache is often caused by cerebrospinal fluid leakage. Elevating the head of the bed or having the client lie flat can reduce cerebrospinal fluid pressure and alleviate the headache. These positions help prevent further fluid loss and relieve discomfort. While acetaminophen or caffeine may help in relieving the headache, changing the client's position is the priority to address the underlying cause. Resting in a dark room may be beneficial for headache relief but is not the priority intervention compared to adjusting the position to manage cerebrospinal fluid pressure.

4. When teaching a group of mothers of young children about emergency care for poisoning, which of the following statements should be included?

• A. Induce vomiting immediately after the poison ingestion
• B. Call the local Poison Control Center after inducing vomiting
• C. Call the Poison Control Center prior to any interventions
• D. Take the child to the emergency department before calling the Poison Control Center

Correct answer: C

Rationale: The correct statement to include when teaching about emergency care for poisoning is to call the Poison Control Center prior to any interventions. This is important because the Poison Control Center can provide guidance on the appropriate steps to take based on the type of poisoning, the amount ingested, and the age of the child. Inducing vomiting without professional advice can sometimes do more harm than good. Choice A is incorrect because inducing vomiting immediately is not recommended without consulting with professionals. Choice B is incorrect as it suggests calling the Poison Control Center after inducing vomiting, which is not the recommended sequence. Choice D is incorrect because it is advisable to contact the Poison Control Center first before taking the child to the emergency department.

5. A client who is bedridden after a stroke is at risk for developing pressure ulcers. Which nursing intervention is most important in preventing this complication?

• A. Apply lotion to the skin every 4 hours.
• B. Reposition the client every 2 hours.
• C. Elevate the head of the bed 30 degrees.
• D. Massage the skin at least twice a day.

Correct answer: B

Rationale: Repositioning the client every 2 hours is crucial in preventing pressure ulcers in bedridden clients. This intervention helps in relieving pressure on specific areas of the body, promoting circulation, and reducing the risk of tissue damage. Applying lotion every 4 hours (Choice A) may not address the root cause of pressure ulcers. Elevating the head of the bed (Choice C) is beneficial for some conditions but not specifically targeted at preventing pressure ulcers. Massaging the skin at least twice a day (Choice D) can actually increase the risk of skin breakdown in individuals at risk for pressure ulcers by causing friction and shearing forces on the skin.
