Exam Cram NCLEX RN Practice Questions

1. The nurse is caring for a newborn infant after surgical intervention for imperforate anus. The nurse should place the infant in which position in the postoperative period?

A. Supine with no head elevation
B. Side-lying with the legs flexed
C. Side-lying with the legs extended
D. Supine with the head elevated 30 degrees

Correct answer: B

Rationale: After surgical intervention for imperforate anus, the infant should be placed in a side-lying position with the legs flexed. This position helps reduce edema and pressure on the surgical site, preventing strain and promoting comfort. Placing the infant supine with no head elevation (Choice A) doesn't offer adequate support and may increase pressure on the area. Side-lying with the legs extended (Choice C) doesn't help reduce edema and pressure effectively. Placing the infant supine with the head elevated 30 degrees (Choice D) isn't recommended as it may not provide adequate support and comfort needed for recovery.

2. Why are subdural hemorrhages more common in the elderly?

A. Increased anticoagulant use
B. Increased risk of falls
C. Brain atrophy
D. Inconsistent care giving

Correct answer: C

Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.

3. What is the likely cause of pericarditis in a young patient?

A. Heart failure
B. Acute MI
C. Hypertension
D. Infectious processes

Correct answer: D

Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.

4. The nurse assesses a patient suspected of having meningitis. Which of the following is a common clinical manifestation of this condition?

A. A high WBC count and decreased level of consciousness
B. A high WBC count and manic activity
C. A low WBC count and manic activity
D. A low WBC count and decreased level of consciousness

Correct answer: A

Rationale: The correct answer is 'A high WBC count and decreased level of consciousness.' Meningitis is often caused by an infectious organism, leading to an increase in Intracranial Pressure (ICP), which can result in decreased level of consciousness. While meningitis can trigger an inflammatory response, it typically presents with an elevated white blood cell (WBC) count rather than a low WBC count. Manic activity is not a common clinical manifestation of meningitis; instead, patients may exhibit altered mental status, confusion, or lethargy.

5. A patient is admitted to the same-day surgery unit for a liver biopsy. Which of the following laboratory tests assesses coagulation? Select one that doesn't apply.

A. Partial thromboplastin time
B. Prothrombin time
C. Platelet count
D. Hemoglobin

Correct answer: D

Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.
