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.
Which statement, from a participant attending the class on AIDS prevention, indicates an understanding on how to reduce transmission of HIV?
- A. Mother's who are HIV positive should still be encouraged to breastfeed their babies because beast milk is superior to cow's milk
- B. I think a needle exchange program, where clean needles are exchanged for dirty needles, should be offered in every city
- C. Females taking birth control pills are protected from getting HIV
- D. It's okay to use natural skin condoms since they offer the same protection as the latex condoms
Correct Answer: B
Rationale: The correct answer is B because implementing a needle exchange program is an effective way to reduce transmission of HIV among intravenous drug users. By providing clean needles in exchange for dirty needles, the risk of sharing contaminated needles and spreading the virus is significantly reduced. This approach also helps prevent the transmission of other bloodborne diseases, such as Hepatitis C. The other statements do not demonstrate an understanding of how to reduce HIV transmission - for example, encouraging breastfeeding for HIV-positive mothers can transmit the virus to the baby, birth control pills do not protect against HIV, and natural skin condoms do not offer the same level of protection as latex condoms.
Parents have a concern that their child is depressed. The nurse relates that which characteristic best describes children with depression?
- A. Increased range of affective response
- B. Preoccupation with need to perform well in school
- C. Change in appetite, resulting in weight loss or gain
- D. Tendency to prefer play instead of schoolwork
Correct Answer: C
Rationale: Change in appetite, resulting in weight loss or gain, is a common characteristic seen in children with depression. Some children may experience a significant decrease in appetite, leading to weight loss, while others may have an increased appetite, resulting in weight gain. This change in eating habits is often a noticeable sign that may indicate the presence of depression in children. It is important for parents and caregivers to be aware of any significant changes in a child's eating patterns and behavior, as it could be a potential indicator of underlying mental health issues such as depression.
In the newborn, intramuscular phytonadione (vitamin K) is administered into which muscle?
- A. Deltoid
- B. Dorsogluteal
- C. Vastus medialis
- D. Vastus lateralis
Correct Answer: D
Rationale: In newborns, intramuscular phytonadione (vitamin K) is typically administered into the vastus lateralis muscle. This muscle is located on the front of the thigh and is a commonly used site for IM injections in infants due to its large muscle mass, accessibility, and low risk of hitting major nerves or blood vessels. The vastus lateralis muscle is considered a safe and effective site for administering medications to newborns.
A nurse is assessing a child with an unrepaired ventricular septal defect. Which heart sound does the nurse expect to assess?
- A. Palpitations
- B. Wheeze
- C. Murmur
- D. Physiologic splitting
Correct Answer: C
Rationale: A ventricular septal defect (VSD) is a congenital heart defect characterized by a hole in the septum that separates the heart's two lower chambers (ventricles). When assessing a child with an unrepaired VSD, the nurse would expect to hear a murmur. The murmur is typically described as a harsh, holosystolic (pansystolic) murmur, best heard at the left lower sternal border. This murmur occurs due to the turbulent blood flow across the defect during systole. It is important for the nurse to recognize this characteristic murmur associated with a VSD to facilitate appropriate management and follow-up care for the child.
