NCLEX RN Practice Questions Exam Cram
1. The nurse is caring for a newborn with a suspected diagnosis of imperforate anus. The nurse monitors the infant, knowing that which is a clinical manifestation associated with this disorder?
- A. Bile-stained fecal emesis
- B. The passage of currant jelly-like stools
- C. Failure to pass meconium stool in the first 24 hours after birth
- D. Sausage-shaped mass palpated in the upper right abdominal quadrant
Correct answer: C
Rationale: Imperforate anus is the incomplete development or absence of the anus in its normal position in the perineum. Failure to pass meconium stool within the first 24 hours after birth is a key clinical manifestation associated with this disorder. This finding should prompt further assessment to confirm the suspected diagnosis. Other assessment findings in imperforate anus may include absence or stenosis of the anal rectal canal, presence of an anal membrane, and an external fistula to the perineum. Options A, B, and D describe findings typically noted in intussusception, a different condition characterized by bowel obstruction and telescoping of the intestines that can present with bile-stained fecal emesis, the passage of currant jelly-like stools, and a sausage-shaped mass palpated in the upper right abdominal quadrant.
2. A child has just been diagnosed with juvenile idiopathic arthritis. Which of the following statements about the disease is most accurate?
- A. The child has a poor chance of recovery without joint deformity.
- B. Most children progress to adult rheumatoid arthritis.
- C. Nonsteroidal anti-inflammatory drugs are the first choice in treatment.
- D. Physical activity should be minimized.
Correct answer: C
Rationale: The correct answer is that nonsteroidal anti-inflammatory drugs are the first choice in treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs are important as a first-line treatment and typically require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Choice A is incorrect as early treatment can improve outcomes and prevent joint deformities. Choice B is incorrect as juvenile idiopathic arthritis does not necessarily progress to adult rheumatoid arthritis. Choice D is incorrect as physical activity should be encouraged in children with arthritis to maintain joint mobility and overall health.
3. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
4. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
5. Which of the following can cause coup-contrecoup injuries?
- A. Rotational forces
- B. Deformation forces
- C. Deceleration forces
- D. Acceleration forces
Correct answer: C
Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
