1. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

2. Which of the following diseases or disorders is acute?

• A. Pneumonia
• B. Paralysis
• C. Alzheimer's disease
• D. Diabetes

Correct answer: A

Rationale: The correct answer is Pneumonia. Pneumonia is an acute illness characterized by inflammation of the air sacs in the lungs. It comes on suddenly and typically lasts for a short duration. Treatment can help cure pneumonia. Paralysis, Alzheimer's disease, and Diabetes are chronic conditions. Paralysis is the loss of muscle function in part of the body, usually permanent. Alzheimer's disease is a progressive brain disorder leading to memory loss and cognitive decline, and it is incurable. Diabetes is a chronic condition that affects how your body turns food into energy, and it requires lifelong management. Therefore, Pneumonia is the only acute condition among the options provided.

3. Which of the following medications taken by the patient is least likely to cause urine discoloration?

• A. Sulfasalazine
• B. Levodopa
• C. Phenolphthalein
• D. Aspirin

Correct answer: D

Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.

4. Which of the following statements best describes postural drainage as part of chest physiotherapy?

• A. Tapping on the chest wall to loosen secretions
• B. Squeezing the abdomen to increase expansion of the upper chest
• C. Using gravity to move secretions in the lung tissue
• D. Dilating the trachea to facilitate better release of secretions

Correct answer: C

Rationale: Postural drainage is a technique used in chest physiotherapy for clients with accumulated lung secretions. It involves positioning the client to utilize gravity in moving secretions from the lungs. Choice A, tapping on the chest wall, describes percussion, not postural drainage. Choice B, squeezing the abdomen, is not a correct description of postural drainage. Choice D, dilating the trachea, is not related to postural drainage but may be associated with airway clearance techniques.

5. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.
