1. Pain in the lower extremities due to peripheral artery disease usually worsens:

• A. with rest because blood flow increases.
• B. with elevation of the extremity because blood is diverted away.
• C. when the leg is in a dependent position because blood pools.
• D. when the leg is touched or massaged because cytokines are released.

Correct answer: B

Rationale: In peripheral artery disease, pain in the lower extremities worsens with the elevation of the extremity because it diverts blood flow away from the affected area, exacerbating the pain. Choices A, C, and D are incorrect. Resting doesn't increase blood flow, a dependent position doesn't lead to blood pooling in this context, and pain worsening due to touch or massage is not a typical feature of peripheral artery disease.

2. Which information would indicate more teaching is needed regarding hypersensitivity reactions? Type _______ hypersensitivity reactions involve an antibody response.

• A. I
• B. II
• C. III
• D. IV

Correct answer: D

Rationale: The correct answer is D: Type IV hypersensitivity reactions involve cell-mediated immunity, not an antibody response. This question tests knowledge of hypersensitivity reactions and their classification. Type I hypersensitivity reactions involve IgE antibodies, Type II involves IgG or IgM antibodies, and Type III involves immune complex deposition. Type IV hypersensitivity reactions are delayed and involve T cells, not antibodies. Therefore, if a person believes that Type IV hypersensitivity reactions involve an antibody response, more teaching is required.

3. A client with heart failure is experiencing pulmonary edema. Which intervention should be prioritized?

• A. Administer diuretics to reduce fluid overload.
• B. Position the client in high-Fowler's position.
• C. Administer oxygen therapy to improve oxygenation.
• D. Restrict fluid intake to prevent further fluid overload.

Correct answer: C

Rationale: In a client experiencing pulmonary edema due to heart failure, the priority intervention is to administer oxygen therapy to improve oxygenation. This helps in increasing the oxygen levels in the blood, thereby improving tissue perfusion and reducing the workload on the heart. Positioning the client in high-Fowler's position can also aid in improving oxygenation, but administering oxygen therapy directly addresses the immediate need for increased oxygen levels. Administering diuretics to reduce fluid overload and restricting fluid intake are important interventions in heart failure management, but in the acute situation of pulmonary edema, oxygen therapy takes precedence to ensure adequate oxygen supply to vital organs.

4. When a Tae Kwon Do (TKD) master applies downward pressure just above the elbow joint on an attacker who immediately collapses to the ground, which reflex is applicable to this example?

• A. Golgi tendon reflex
• B. Myotatic reflex
• C. Withdrawal reflex
• D. Crossed-extensor reflex

Correct answer: A

Rationale: The Golgi tendon reflex is the correct answer. This reflex protects the muscle and tendons from excessive force by causing the muscle to relax. In this scenario, the downward pressure applied just above the elbow joint triggers the Golgi tendon reflex, resulting in the attacker's collapse. The other options are incorrect: - The myotatic reflex (also known as the stretch reflex) is responsible for contracting a muscle in response to its stretch, not relaxing it. - The withdrawal reflex is a spinal reflex that moves a body part away from a painful stimulus, not directly related to the scenario described. - The crossed-extensor reflex is a reflex that occurs on the opposite side of the body in response to a withdrawal reflex, which is not the case in this situation.

5. In gout, a man has developed large, hard nodules around his toes and elbows. The phase of gout he is in is:

• A. asymptomatic.
• B. acute flare.
• C. the intercritical period.
• D. chronic gout.

Correct answer: D

Rationale: The man's presentation of large, hard nodules around his toes and elbows is indicative of tophi formation, which is characteristic of chronic gout. Tophi are deposits of uric acid crystals that can develop over time in untreated or poorly managed gout. During the chronic phase of gout, tophi can form in joints, soft tissues, and organs. Asymptomatic refers to a phase where there are no symptoms present. Acute flare is characterized by sudden and severe joint pain and inflammation. The intercritical period is the time between gout attacks when the patient is symptom-free.
