Nursing Elites

1. As you are walking in the park, a huge black Labrador runs up to you and places his paws on your shoulders. Immediately your heart starts racing, you feel palpitations, anxiety, and your hands become a little shaky. The nurse knows that this response is primarily caused by:

• A. cerebral cortex.
• B. somatic nervous system.
• C. limbic system.
• D. autonomic nervous system.

Correct answer: D

Rationale: The autonomic nervous system controls involuntary bodily functions like heart rate, respiration, and sweating. In the given scenario, the 'fight or flight' response is activated, leading to increased heart rate, palpitations, anxiety, and shaky hands. The cerebral cortex is involved in conscious thought processes and decision-making, not the immediate physiological response observed here. The somatic nervous system regulates voluntary movements, while the limbic system is responsible for emotions and memory, but the autonomic nervous system is primarily responsible for the physiological responses seen in this situation.

2. The college health nurse is providing health education for freshmen. Which of the following pieces of information about immunizations is applicable to individuals of this age group?

• A. The oral polio vaccine should be updated.
• B. The yearly administration of flu vaccine is recommended.
• C. The tetanus toxoid should be within 2 years.
• D. The administration of hepatitis A vaccine is mandatory.

Correct answer: B

Rationale: For freshmen in college, the yearly administration of the flu vaccine is recommended. This is important to protect against seasonal influenza outbreaks that can spread rapidly in close living quarters such as dormitories. Choice A is incorrect as oral polio vaccine is not typically given to individuals of this age group. Choice C is incorrect as tetanus toxoid boosters are usually recommended every 10 years, not within 2 years. Choice D is incorrect as the administration of the hepatitis A vaccine is not mandatory for all individuals in this age group.

3. 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.

4. When a healthcare professional notices that a patient has type O blood, they realize that anti-_____ antibodies are present in the patient's body.

• A. A only
• B. B only
• C. A and B
• D. O

Correct answer: C

Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens. Therefore, the correct answer is C. Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies. Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.

5. When educating a patient starting on oral contraceptives, what should the nurse include regarding the medication's effectiveness?

• A. Oral contraceptives are 100% effective when taken correctly.
• B. Oral contraceptives are effective immediately after starting.
• C. Oral contraceptives are less effective if taken with antibiotics.
• D. Oral contraceptives are less effective if taken with food.

Correct answer: C

Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics as they may interfere with the contraceptive's efficacy, potentially leading to decreased effectiveness. Therefore, patients should be advised to use additional contraception methods if they are also taking antibiotics. Choice A is incorrect because while oral contraceptives are highly effective, they are not 100% foolproof. Choice B is incorrect as oral contraceptives may take some time to reach their full effectiveness after starting. Choice D is incorrect since taking oral contraceptives with food does not necessarily impact their effectiveness.
