The screening test for PKU is most reliable if the blood sample is:
- A. from cord blood.
- B. taken 14 days after birth.
- C. taken before oral feedings are initiated.
- D. fresh blood from the heel.
Correct Answer: D
Rationale: The screening test for PKU (Phenylketonuria) is most reliable when the blood sample is fresh and taken from the heel. This is because the test requires a small amount of blood, and obtaining a fresh sample from the heel minimizes the risk of contamination and ensures accurate results. Additionally, collecting the blood sample from the heel is less invasive for the newborn and is a common practice for newborn screening tests. Blood samples taken from cord blood, 14 days after birth, or before oral feedings are initiated may not provide accurate results for the PKU screening test.

The parent of a 2-week-old infant, exclusively breastfed, asks the nurse if fluoride supplements are needed. What is the nurse's best response?
- A. "She needs to begin taking them now."
- B. "They are not needed if you drink fluoridated water."
- C. "She may need to begin taking them at age 4 months."
- D. "She can have infant cereal mixed with fluoridated water instead of supplements."
Correct Answer: B
Rationale: The nurse's best response to the parent of a 2-week-old infant, exclusively breastfed, regarding the need for fluoride supplements is that they are not needed if the infant is already drinking fluoridated water. Fluoride supplements are typically recommended for infants who are not receiving enough fluoride through their water source. Breast milk itself does not contain a significant amount of fluoride, but if the family's water supply is fluoridated, the infant will likely receive an adequate amount of fluoride without the need for supplements. It is important for the parent to verify the fluoride content of their water supply with their local water utility to ensure the infant is receiving the appropriate amount of fluoride for dental health.
minutes after birth the normal heart rate of the infant may range between:
- A. 100 and 180
- B. 130 and 170
- C. 120 and 160
- D. 100 and 130
Correct Answer: C
Rationale: The normal heart rate of a newborn infant is typically between 120 and 160 beats per minute within the first minutes after birth. This range is considered normal for a healthy newborn and reflects the development of the infant's cardiovascular system. It is important to monitor the newborn's heart rate closely in the immediate post-birth period to ensure that it remains within this normal range. Any deviations from this range may indicate a need for further evaluation and intervention.
Almost all of the diseases detected in neonatal screening programs have a very low prevalence; the strategy is to use the initial screening test to separate a highly suspect group from normal and then follow this suspect group aggressively. Of the following, the disease that has low prevalence rendering it not useful for neonatal screening testing is
- A. phenylketonuria
- B. hypothyroidism
- C. cystic fibrosis
- D. neuroblastoma
Correct Answer: D
Rationale: Neuroblastoma has a very low prevalence and is not typically screened for in neonatal programs due to its rarity and the inefficiency of mass screening for such a condition.
Which of the ff symptoms is observed in the client with Right Sided Heart Failure?
- A. Dependent pitting edema
- B. Orthopnea
- C. Exertional dyspnea
- D. Hemoptysis CARING FOR CLIENTS UNDERGOING CARDIOVASCULAR SURGERY
Correct Answer: A
Rationale: Right-sided heart failure is characterized by the inability of the right side of the heart to pump blood effectively, leading to fluid accumulation in the systemic venous system. This fluid overload typically manifests as signs of congestion in the peripheral tissues. Dependent pitting edema is a classic symptom of right-sided heart failure, where swelling is noted in the lower extremities and sacral area, worsening later in the day due to the effects of gravity. Orthopnea (B) and exertional dyspnea (C) are more indicative of left-sided heart failure, where congestion occurs in the pulmonary system. Hemoptysis (D) refers to coughing up blood and is not a classic symptom of heart failure but may be seen in conditions such as pulmonary embolism or infection.
Pick one:
- A. Diabetes mellitus is three times more common in Hispanics than in Blacks or Whites.
- B. Type 2 diabetes mellitus is less common than type 1 diabetes mellitus.
- C. Approximately one-half of the clients diagnosed with type 2 are obese.
Correct Answer: A
Rationale: The statement "Diabetes mellitus is three times more common in Hispanics than in Blacks or Whites" is accurate and supported by data. Studies have shown that diabetes mellitus, particularly type 2 diabetes, is more prevalent among Hispanic populations compared to Black or White populations. Factors such as genetic predisposition, lifestyle choices, and socioeconomic status can contribute to this disparity. It is important for healthcare providers to be aware of these trends to provide appropriate and culturally sensitive care to individuals at higher risk for diabetes.
