1. What is the priority action when a healthcare professional misreads a glucose reading and administers excess insulin?

A. Administer IV glucose
B. Monitor for hyperglycemia
C. Monitor for hypoglycemia
D. Document the incident

Correct answer: C

Rationale: The priority action when a healthcare professional misreads a glucose reading and administers excess insulin is to monitor for hypoglycemia. Excess insulin can lead to dangerously low blood sugar levels (hypoglycemia), which can result in serious complications. Monitoring for hypoglycemia allows for timely identification and intervention to prevent harm. Administering IV glucose may be necessary if hypoglycemia occurs. Monitoring for hyperglycemia is not the priority in this situation, as excess insulin would lower blood sugar levels. Documenting the incident is important for reporting and quality improvement purposes but should not take precedence over ensuring patient safety by monitoring for hypoglycemia.

2. What ECG changes are seen in hypokalemia?

A. Flattened T waves on the ECG
B. Elevated ST segments on the ECG
C. Widened QRS complex
D. Prominent U waves on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

3. What should be taught to a patient following cataract surgery?

A. Avoid NSAIDs
B. Wear dark glasses when outdoors
C. Report green or yellow drainage immediately
D. Itching is normal unless accompanied by pain and nausea

Correct answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.

4. What are the manifestations of osteomyelitis?

A. Localized pain, swelling, erythema
B. Elevated white blood cells
C. Elevated calcium levels
D. Low potassium levels

Correct answer: A

Rationale: Osteomyelitis often manifests as localized pain, swelling, and erythema due to infection in the bone. These symptoms are characteristic of inflammation and infection in the bone tissue. Elevated white blood cells (Choice B) may be present as part of the body's immune response to the infection but are not specific manifestations of osteomyelitis. Elevated calcium levels (Choice C) and low potassium levels (Choice D) are not typically associated with osteomyelitis.

5. A patient has been diagnosed with a thrombotic stroke. What are the expected manifestations?

A. Gradual loss of function on one side of the body
B. Sudden loss of consciousness
C. Seizures and confusion
D. Loss of sensation in the affected limb

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.
