1. Which of the following statements indicates more teaching is needed regarding secondary lymph organs? ________is/are a secondary lymph organ.

• A. The spleen
• B. Peyer's patches
• C. Adenoids
• D. The liver

Correct answer: D

Rationale: The correct answer is D, 'The liver.' The liver is not a secondary lymph organ. Secondary lymph organs are primarily involved in the immune response, such as the spleen, Peyer's patches, and adenoids. The spleen filters blood and is essential for immune function. Peyer's patches are located in the small intestine and help protect against pathogens. Adenoids are located in the throat and play a role in immune defense. Therefore, the liver is the incorrect choice as it is not part of the secondary lymph organ system.

2. Which of the following types of vitamin or mineral deficiency can cause megaloblastic anemia and is associated with lower extremity paresthesias?

• A. Vitamin B12
• B. Folate
• C. Iron
• D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 deficiency can lead to megaloblastic anemia, a condition characterized by the production of abnormally large and immature red blood cells. Lower extremity paresthesias, such as tingling or numbness, are common neurological symptoms associated with vitamin B12 deficiency. Folate deficiency can also cause megaloblastic anemia but is not typically linked to lower extremity paresthesias. Iron deficiency leads to microcytic anemia, not megaloblastic anemia. Vitamin K deficiency is associated with bleeding tendencies, not megaloblastic anemia or paresthesias.

3. A patient presents with a sudden onset of severe chest pain radiating to his back. His blood pressure is significantly higher in the right arm than in the left arm. Which of the following conditions is most likely?

• A. Acute myocardial infarction
• B. Pulmonary embolism
• C. Aortic dissection
• D. Pericarditis

Correct answer: C

Rationale: The correct answer is C, aortic dissection. Aortic dissection is characterized by sudden, severe chest pain that can radiate to the back. The discrepancy in blood pressure between the arms (higher in the right arm) is known as a 'pulse deficit' and is a classic finding in aortic dissection. This condition involves a tear in the inner layer of the aorta, leading to the abnormal flow of blood within the aortic wall. Acute myocardial infarction (choice A) presents with chest pain but typically does not cause discrepancies in blood pressure between arms. Pulmonary embolism (choice B) usually presents with chest pain and difficulty breathing but does not cause unequal blood pressures in the arms. Pericarditis (choice D) can cause chest pain exacerbated by breathing or lying down, but it does not typically lead to differences in blood pressure between arms.

4. What potential risk should the nurse identify as being associated with infliximab (Remicade) in the treatment of rheumatoid arthritis?

• A. Risk for infection
• B. Risk for decreased level of consciousness
• C. Risk for nephrotoxicity
• D. Risk for hepatotoxicity

Correct answer: A

Rationale: The correct answer is A: Risk for infection. Infliximab (Remicade) is a medication used to treat autoimmune conditions like rheumatoid arthritis. One of the main risks associated with infliximab is an increased susceptibility to infections due to its immunosuppressive effects. This drug works by targeting specific proteins in the body's immune system, which can weaken the body's ability to fight off infections. Choices B, C, and D are incorrect because infliximab is not typically associated with decreased level of consciousness, nephrotoxicity, or hepatotoxicity. It is important for healthcare providers to monitor patients on infliximab for signs of infection and educate them on the importance of infection prevention strategies.

5. While in an induced coma for 3 weeks, a badly burned firefighter awakens and thanks his son for singing Happy Birthday to him a week earlier. Which part of the brain is responsible for allowing him to hear and comprehend while comatose?

• A. Cerebellum
• B. Thalamus
• C. Temporal lobe
• D. Occipital lobe

Correct answer: C

Rationale: The temporal lobe is responsible for processing auditory information, allowing the patient to hear and comprehend while in a coma. The cerebellum is primarily associated with coordination and balance, not auditory processing. The thalamus serves as a relay station for sensory information but is not specifically responsible for auditory processing. The occipital lobe is mainly involved in processing visual information, not auditory functions.
