Which of the following organisms is responsible for the development of rheumatic fever?
- A. Streptococcal pneumonia
- B. Haemophilus influenza
- C. Group Aß-hemolytic streptococcus
- D. Staphylococcus aureus
Correct Answer: C
Rationale: Rheumatic fever is an inflammatory disease that can develop after an untreated or inadequately treated infection with group Aß-hemolytic streptococcus bacteria, particularly Streptococcus pyogenes. This bacteria causes strep throat, which if left untreated, can lead to complications such as rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain. It is important to promptly treat streptococcal infections with antibiotics to prevent the development of rheumatic fever.

Which would be best for the nurse to use when determining the temperature of a preterm infant under a radiant heater?
- A. Axillary sensor TestBankWorld.org
- B. Tympanic membrane sensor
- C. Rectal mercury glass thermometer
- D. Rectal electronic thermometer
Correct Answer: B
Rationale: A tympanic membrane sensor or tympanic thermometer is the best option for determining the temperature of a preterm infant under a radiant heater. Tympanic thermometers are quick and non-invasive, making them ideal for use in neonatal care. They provide accurate readings by measuring the infrared heat waves coming from the eardrum. This method is preferred over other options like axillary sensors, rectal mercury thermometers, and rectal electronic thermometers, which may not be as efficient or suitable for use with preterm infants.
Where do the lesions of atopic dermatitis (eczema) most commonly occur in the infant? (Select all that apply.)
- A. Cheeks
- B. Buttocks
- C. Extensor surfaces of arms and legs
- D. Back
Correct Answer: A
Rationale: In infants with atopic dermatitis (eczema), the lesions most commonly occur on the cheeks (option A) and the extensor surfaces of the arms and legs (option C). The cheeks are a common site of involvement due to increased exposure to irritants and saliva from drooling. The extensor surfaces of the arms and legs are also frequently affected due to scratching and rubbing against clothing. While atopic dermatitis can occur in other areas such as the buttocks, back, and trunk, the cheeks and extensor surfaces are the most common locations in infants.
At the present time, the best treatment for cancer is complete __________ before metastasis occurs:
- A. Chemotherapy
- B. Radiation
- C. Surgical removal
- D. All of the above
Correct Answer: C
Rationale: The best treatment for cancer at the present time is complete surgical removal before metastasis occurs. Surgery is often the most effective method to remove the primary tumor and eliminate cancer cells in the affected area. While chemotherapy and radiation therapy are important in treating cancer, surgical removal of the tumor provides the best chance for complete eradication of cancer cells, especially if it is done before the cancer has spread to other parts of the body.
What does the surgical closure of the ductus arteriosus do?
- A. Stop the loss of unoxygenated blood to the systemic circulation
- B. Decrease the edema in legs and feet
- C. Increase the oxygenation of blood
- D. Prevent the return of oxygenated blood to the lungs
Correct Answer: A
Rationale: The ductus arteriosus is a fetal blood vessel that allows blood to bypass the lungs while in utero. After birth, the ductus arteriosus should close to redirect blood flow through the lungs for oxygenation. Surgical closure of the ductus arteriosus is performed to prevent the shunting of unoxygenated blood from the pulmonary artery to the aorta, therefore stopping the loss of unoxygenated blood to the systemic circulation. This helps to ensure that oxygenated blood is properly circulated to the body tissues and organs.
The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby's formula faster. What should the nurse recommend?
- A. Never heat a bottle in a microwave oven.
- B. Heat only 10 ounces or more.
- C. Always leave bottle top uncovered to allow heat to escape.
- D. Shake bottle vigorously for at least 30 seconds after heating.
Correct Answer: A
Rationale: The nurse should recommend never heating a bottle in a microwave oven. Microwaves do not heat liquids evenly, and there is a risk of creating hot spots in the formula, which can burn the baby's mouth and throat. It is safer to heat the formula by placing the bottle in warm water or using a bottle warmer to ensure uniform heating throughout.
