NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
Newborns are routinely screened for phenylketonuria. The nursery nurse ensures that this screening test is performed:
Correct Answer: B
Rationale: The infant has not ingested any protein immediately after birth, which is necessary to detect excessive serum phenylalanine. It is important that the infant take in 2-3 full days of milk or formula feedings to preclude a false-negative reading. At 2-3 days of age, inadequate milk could have been ingested owing to a delay in the initial feeding. The biochemical buildup of serum phenylalanine is detectable after 2-3 days of milk or formula ingestion.
Question 2 of 5
The nurse is assessing a client with suspected preeclampsia. Which finding is most indicative of this condition?
Correct Answer: A
Rationale: Proteinuria is a hallmark of preeclampsia, reflecting renal involvement due to endothelial damage. Hypertension (not hypotension), weight gain, and oliguria (not polyuria) are also common.
Question 3 of 5
Which diet is associated with an increased risk of colorectal cancer?
Correct Answer: C
Rationale: High-fat, refined carbohydrate diets are linked to colorectal cancer due to increased bile acid production and reduced fiber intake, which promote carcinogenesis. The other diets are less strongly associated.
Question 4 of 5
The nurse is caring for a client with a diagnosis of ectopic pregnancy. Which symptom is most likely to be present?
Correct Answer: A
Rationale: Ectopic pregnancy causes sudden abdominal pain from tubal stretching or rupture. Painless bleeding is more typical of placenta previa fetal heart tones are absent and fever is not common.
Question 5 of 5
A client with a history of a thyroidectomy is being discharged. The nurse should teach the client to:
Correct Answer: A
Rationale: Hypocalcemia post-thyroidectomy (due to parathyroid damage) causes symptoms like tingling or tetany, requiring monitoring. Iodine foods, bedtime dosing, and fluid limits are not primary concerns.
