The nurse is drawing blood from the diabetic patient for a glycosylated hemoglobin test. She explains to the woman that the test is used to determine:

  • A. the highest glucose level in the past week.
  • B. her insulin level.
  • C. glucose levels over the past several months.
  • D. her usual fasting glucose level.
Correct Answer: C

Rationale: The correct answer is C. The glycosylated hemoglobin (HbA1c) test is used to determine the average glucose levels over the past several months (approximately 2-3 months). This test measures the amount of glucose that has been bound to hemoglobin in red blood cells, providing an indication of the patient's overall blood sugar control. This is particularly important for diabetic patients, as it helps healthcare providers assess the effectiveness of the management plan and make necessary adjustments to prevent complications associated with high blood sugar levels over time. The other options provided do not accurately describe what the glycosylated hemoglobin test measures.

Which is the most critical physiologic change required of the newborn?

  • A. Closure of fetal shunts in the heart
  • B. Stabilization of fluid and electrolytes
  • C. Body-temperature maintenance
  • D. Onset of breathing
Correct Answer: D

Rationale: The most critical physiologic change required of the newborn is the onset of breathing. Prior to birth, the fetus receives oxygen from the mother's blood through the placenta. However, once the newborn is delivered, it needs to begin breathing on its own to support oxygen exchange and remove carbon dioxide from the body. The respiratory system must transition from a fluid-filled state in the womb to an air-filled state outside the womb. The onset of breathing is essential for the newborn's survival and initiates the process of oxygenation of tissues and removal of carbon dioxide, which are vital for metabolism and overall physiological functioning. While closure of fetal shunts, stabilization of fluid and electrolytes, and body-temperature maintenance are also important changes that occur in the newborn, the onset of breathing is the most critical to ensure proper oxygenation of the body's tissues.

Persons with up to 70% prevalence of peculiar facial anatomy are considered risk factors for obstructive sleep apnea EXCEPT

  • A. hypotonia
  • B. developmental delay
  • C. central adiposity
  • D. hypothyroidism
Correct Answer: D

Rationale: Hypothyroidism is not a typical risk factor for obstructive sleep apnea.

Recent studies indicate that a deficiency of which vitamin correlates with increased morbidity and mortality in children with measles?

  • A. A
  • B. C
  • C. Niacin
  • D. Folic acid
Correct Answer: A

Rationale: Recent studies have shown that a deficiency of vitamin A correlates with increased morbidity and mortality in children with measles. Vitamin A plays a crucial role in supporting the immune system and helps protect against severe complications of measles, such as pneumonia and vision problems. Children with measles are at higher risk of vitamin A deficiency due to factors such as decreased intake and increased utilization of vitamin A during infection. Providing vitamin A supplementation to children with measles has been shown to reduce the severity of the disease and improve outcomes. Therefore, ensuring adequate vitamin A levels is essential in the management of children with measles to reduce morbidity and mortality.

Several types of seizures can occur in the newborn. Which is characteristic of clonic seizures?

  • A. Apnea
  • B. Tremors
  • C. Rhythmic jerking movements
  • D. Extensions of all four limbs
Correct Answer: C

Rationale: Clonic seizures are characterized by rhythmic jerking movements, which can be brief and repetitive. These movements are typically observed in the arms and legs. During clonic seizures, the baby may display a pattern of contractions and relaxation of muscle groups, resulting in the jerking motion. This distinguishes clonic seizures from other types of seizures, making it the characteristic feature associated with this particular seizure type in newborns.

Nearly all cervical carcinomas contain human papillomavirus (HPV). Which of the following types is never associated with such malignancy?

  • A. type6
  • B. type 16
  • C. type 18
  • D. type 31
Correct Answer: A

Rationale: HPV type 6 is typically associated with low-grade lesions and genital warts, not cervical carcinoma.
