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.
You are assigned to evaluate the outcome of fecal occult blood test as a screening test for patients with bowel cancer. The total number of patients who underwent the test is 2030; in those whom the disease is confirmed are 30. The results of fecal occult blood test are as follows: in 20 patients who has a confirmed bowel cancer (truly positive), and in 180 patients who don't have the disease (falsely positive); in 10 patients who truly has the disease (falsely negative), and in 1820 patients who are not affected by the disease (truly negative). All the following statements are true EXCEPT
- A. the prevalence of the disease for those population is 1.48%
- B. the sensitivity of the test is 67%
- C. the specificity of the test is 91%
- D. the positive predictive value is 20%
Correct Answer: A
Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
Extraneural metastasis from primary brain tumors is MOST commonly likely to occur in which tumor?

Place in order the expected sequence of fine motor developmental milestones for an infant beginning with the first milestone achieved and ending with the last milestone achieved. Provide answer using lowercase letters separated by commas (e.g., a, b, c, d, e).
- A. Voluntary palmar grasp
- B. Reflex palmar grasp
- C. Puts objects into a container
- D. Neat pincer grasp
Correct Answer: B
Rationale: 1. Reflex palmar grasp (B) - Infants are born with a reflex called the palmar grasp reflex, which means they automatically close their fingers around an object placed in their palm. This reflex typically disappears around 3-4 months of age.
The nurse is caring for a 3-week-old preterm newborn born at 29 weeks of gestation. While taking vital signs and changing the newborn's diaper, the nurse observes the newborn's color is pink but slightly mottled, arms and legs are limp and extended, hiccups are present, and heart rate is regular and rapid. The nurse should recognize these behaviors as manifestations of:
- A. stress.
- B. subtle seizures.
- C. preterm behavior.
- D. onset of respiratory distress.
Correct Answer: C
Rationale: The behaviors described, such as slightly mottled skin, limp and extended extremities, hiccups, and a rapid but regular heart rate, are typical of preterm newborn behavior. Preterm infants often exhibit these characteristics due to their immature neurological and physiological systems. The mottled skin may be due to the immature vascular system, while the limp and extended extremities are common in preterm newborns as they have less muscle tone compared to full-term infants. Hiccups are also common in newborns, including preterm infants, and are generally not a cause for concern. The rapid heart rate is typical in newborns, particularly in the immediate postnatal period. Therefore, in this scenario, these behaviors are most likely related to the preterm status of the newborn rather than indicating stress, seizures, or respiratory distress.
