1. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?
- A. Peripheral artery disease
- B. Raynaud's disease
- C. Varicose veins
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
2. The nurse identifies a need for additional teaching when the patient who is self-monitoring blood glucose
- A. washes the puncture site using warm water and soap
- B. chooses a puncture site in the center of the finger pad
- C. hangs the arm down for a minute before puncturing the site
- D. says the result of 120 mg indicates good blood sugar control
Correct answer: B
Rationale: The correct answer is B because choosing a puncture site in the center of the finger pad is not recommended for blood glucose monitoring. The recommended sites are the sides of the fingertips. Option A is correct as washing the puncture site using warm water and soap is a good practice. Option C is also correct as hanging the arm down for a minute can help increase blood flow. Option D is incorrect as a blood sugar level of 120 mg/dL may not necessarily indicate good blood sugar control and needs further interpretation.
3. A nurse enters a client's room and finds her on the floor. The client's roommate reports that the client was trying to get out of bed and fell over the bedrail onto the floor. Which of the following statements should the nurse document about this incident?
- A. Found on floor
- B. Client slipped while getting out of bed
- C. Patient fell while attempting to get out of bed
- D. Roommate reported fall
Correct answer: A
Rationale: The correct answer is 'A: Found on floor.' This choice provides a clear and objective account of the situation without adding interpretation or assumptions. It is crucial to document only the facts observed directly. Choices B and C introduce speculation by suggesting how the incident happened, which the nurse did not witness. Choice D is not directly related to the nurse’s observation and should not be documented as the primary incident.
4. Which of the following eye disorders manifests with red eye, pain, and visual acuity changes?
- A. Bacterial conjunctivitis
- B. Acute closed-angle glaucoma
- C. Chronic open-angle glaucoma
- D. Blepharitis
Correct answer: Acute closed-angle glaucoma
Rationale: Acute closed-angle glaucoma presents with symptoms such as a red eye, severe pain, and rapid visual acuity changes due to increased intraocular pressure. This condition is considered an ophthalmologic emergency. Bacterial conjunctivitis typically presents with redness, discharge, and irritation but is not associated with severe pain or visual changes. Chronic open-angle glaucoma is usually asymptomatic until advanced stages and does not typically present with acute pain. Blepharitis involves inflammation of the eyelid margins and is characterized by redness and irritation, but it does not cause severe pain or acute visual changes.
5. A client with a pleural effusion is being assessed by a nurse. Which clinical manifestation does the nurse expect to find?
- A. Decreased breath sounds on the affected side
- B. Hyperresonance on percussion of the affected side
- C. Increased tactile fremitus on the affected side
- D. Tracheal deviation toward the affected side
Correct answer: A
Rationale: In a client with pleural effusion, decreased breath sounds on the affected side are common due to the presence of fluid in the pleural space. Hyperresonance is not expected; dullness on percussion is more likely. Tactile fremitus is typically decreased, not increased, in pleural effusion cases. Tracheal deviation away from the affected side, not toward it, can be seen with large effusions.
