Question 1 of 9
The thymus gland role with the immune system is which of the following?
Correct Answer: D
Rationale: The thymus gland plays a crucial role in the immune system as it is primarily responsible for the maturation and differentiation of T lymphocytes (T cells). T cells are essential for cell-mediated immunity and play a key role in recognizing and attacking pathogens such as bacteria, viruses, and cancer cells. The thymus is where immature T cells mature and undergo education to ensure they can distinguish between self and non-self antigens effectively. This process is crucial for the proper functioning of the immune system to protect the body from infections and diseases.
Question 2 of 9
In teaching a female client who is HIV positive about pregnancy, the nurse would know more teaching is necessary when the client says:
Correct Answer: A
Rationale: Option A indicates a misunderstanding about HIV transmission during pregnancy. In reality, with proper medical care and management during pregnancy and delivery, the risk of transmitting HIV from mother to baby can be significantly reduced but not completely eliminated. The virus can be passed from mother to baby during pregnancy, childbirth, or breastfeeding, but it is not directly from the placenta. This misconception highlights the need for further education and clarification on the modes of HIV transmission from mother to child during pregnancy and delivery. Options B, C, and D all demonstrate understanding and appropriate planning related to HIV and pregnancy.
Question 3 of 9
What is an early clinical manifestation of bilirubin encephalopathy in the newborn?
Correct Answer: C
Rationale: An early clinical manifestation of bilirubin encephalopathy in a newborn is lethargy or irritability. Bilirubin encephalopathy, also known as kernicterus, is a serious condition that occurs when high levels of unconjugated bilirubin build up in the brain tissues. Initially, the baby may become lethargic or irritable due to the toxic effects of bilirubin on the central nervous system. As the condition progresses, symptoms may include poor feeding, high-pitched crying, muscle tone abnormalities, and eventually may lead to more severe consequences such as seizures and irreversible neurological damage. Prompt recognition and treatment of bilirubin encephalopathy are crucial to prevent long-term complications.

Question 5 of 9
A nurse is conducting discharge teaching for parents of a newborn. The nurse instructs the parents on which method of care for the umbilical cord? (Select all that apply.)
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 6 of 9
The nurse is talking to a parent of an infant with heart failure about feeding the infant. Which statement about feeding the child is correct?
Correct Answer: A
Rationale: In infants with heart failure, they may have increased metabolic demands due to their condition. Thus, it may be necessary to increase the caloric density of the infant's formula to ensure adequate nutrition and energy intake. This can help support the infant's growth and provide the necessary energy for their increased metabolic needs. Increasing the amount of formula or feeding too frequently (every 2 hours) may not be necessary and could lead to other issues like overfeeding. Placing a nasal oxygen cannula on the infant during and after each feeding (Option D) is not typically related to feeding practices for an infant with heart failure.
Question 7 of 9
The nurse is evaluating a female child with acute post streptococcal glomerulonephritis for signs of improvement. Which finding typically is the earliest sign of improvement?
Correct Answer: A
Rationale: In a child with acute post streptococcal glomerulonephritis, the earliest sign of improvement typically seen is an increased urine output. This is because one of the hallmark features of glomerulonephritis is decreased urine output (oliguria) or even anuria. As the condition improves, the kidneys start functioning better, leading to increased urine output. Monitoring urine output is crucial in assessing the renal function and overall improvement in patients with glomerulonephritis. While increased appetite, energy level, and decreased diarrhea are important indicators of a child's overall health status, they are not specific signs of improvement in the context of acute post streptococcal glomerulonephritis.
Question 8 of 9
Nearly all cervical carcinomas contain human papillomavirus (HPV). Which of the following types is never associated with such malignancy?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 9 of 9
A brain abscess is a collection of pus within the substance of the brain and is caused by:
Correct Answer: D
Rationale: A brain abscess can be caused by direct invasion of the brain by microorganisms, spread of infection by other organs (such as the heart or lungs), or spread of infection from nearby sites (such as sinuses or the middle ear). In some cases, multiple mechanisms can contribute to the development of a brain abscess. Therefore, the correct answer is that a brain abscess can be caused by all of the above mechanisms.
