Question 2 of 5

A neonate, who was delivered by Cesarean section for a breech presentation, is being examined in the neonatal nursery. For which of the following complications should the nurse carefully assess the baby?

Correct Answer: A

Rationale: A neonate delivered by Cesarean section for a breech presentation is at higher risk for developmental dysplasia of the hips (DDH). Breech presentation, especially frank breech, increases the chance of hip instability and DDH due to the positioning of the legs in utero. DDH is a condition where the ball and socket joint of the hip does not properly form, leading to potential dislocation of the hip joint. It is important for the nurse to carefully assess the neonate for signs of hip dysplasia, such as limited hip abduction or asymmetry in the thigh folds, to facilitate early detection and intervention for optimal outcomes. Legg-Calve-Perthes (LCP), Duchenne muscular dystrophy (DMD), and slipped capital femoral epiphysis (SCFE) are not specifically related to breech delivery, and therefore, are less likely to be

Question 4 of 5

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

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.

Question 5 of 5

Mr. Chua has developed liver cirrhosis. Nurse Bea expects alteration in which laboratory values?

Correct Answer: B

Rationale: Liver cirrhosis affects the liver's ability to produce proteins that are important for blood clotting, including prothrombin. Therefore, in a patient with liver cirrhosis, Nurse Bea would expect an alteration in the prothrombin time, which measures the time it takes for the blood to clot. A prolonged prothrombin time indicates impaired blood clotting function, which is commonly seen in patients with liver disease such as cirrhosis. It is an important laboratory value to monitor in patients with liver cirrhosis to assess their risk of bleeding complications.
