Which is described as an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?
- A. Cyst
- B. Papule
- C. Pustule
- D. Vesicle
Correct Answer: D
Rationale: A vesicle is elevated, circumscribed, superficial, smaller than 1 cm in diameter, and filled with serous fluid. A cyst is elevated, circumscribed, palpable, encapsulated, and filled with liquid or semisolid material. A papule is elevated; palpable; firm; circumscribed; smaller than 1 cm in diameter; and brown, red, pink, tan, or bluish red. A pustule is elevated, superficial, and similar to a vesicle but filled with purulent fluid.

A mother tells the nurse that she does not want her infant immunized because of the discomfort associated with injections. What should the nurse explain?
- A. This cannot be prevented.
- B. Infants do not feel pain as adults do.
- C. This is not a good reason for refusing immunizations.
- D. A topical anesthetic can be applied before injections are given.
Correct Answer: D
Rationale: To minimize the discomfort associated with intramuscular injections, a topical anesthetic agent can be used on the injection site. These include EMLA (eutectic mixture of local anesthetic) and vapor coolant sprays. Pain associated with many procedures can be prevented or minimized by using the principles of atraumatic care. Infants have neural pathways that will indicate pain. Numerous research studies have indicated that infants perceive and react to pain in the same manner as do children and adults. The mother should be allowed to discuss her concerns and the alternatives available. This is part of the informed consent process.
The nurse should know what about Lyme disease?
- A. Very difficult to prevent
- B. Easily treated with oral antibiotics in stages 1, 2, and 3
- C. Caused by a spirochete that enters the skin through a tick bite
- D. Common in geographic areas where the soil contains the mycotic spores that cause the disease
Correct Answer: C
Rationale: Lyme disease is caused by Borrelia burgdorferi, a spirochete spread by ticks. The early characteristic rash is erythema migrans. Tick bites should be avoided by entering tick-infested areas with caution. Light-colored clothing should be worn to identify ticks easily. Long-sleeve shirts and long pants tucked into socks should be the attire. Early treatment of erythema migrans (stage 1) can prevent the development of Lyme disease. Lyme disease is caused by a spirochete, not mycotic spores.

Pertussis vaccination should begin at which age?
- A. Birth
- B. 2 months
- C. 6 months
- D. 12 months
Correct Answer: B
Rationale: The acellular pertussis vaccine is recommended by the American Academy of Pediatrics beginning at age 6 weeks. Infants are at greater risk for complications of pertussis. The vaccine is not given after age 7 years, when the risks of the vaccine become greater than those of pertussis. The first dose is usually given at the 2-month well-child visit. Infants are highly susceptible to pertussis, which can be a life-threatening illness in this age group.
