NCLEX RN Practice Questions Quizlet

1. In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?

Correct Answer: C: Moist, productive cough

Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.

2. The home health nurse visits a male client to provide wound care and finds the client lethargic and confused. His wife states he fell down the stairs two (2) hours ago. The nurse should

Correct Answer: Send him to the emergency room for evaluation

Rationale: In this scenario, the client is presenting with concerning symptoms of lethargy and confusion after a fall. These symptoms could indicate a serious underlying issue, such as a head injury or internal bleeding. The nurse's priority is to ensure the client receives immediate evaluation and treatment to prevent any further harm. Option B is the correct choice as it emphasizes the urgency of the situation. Choices A, C, and D are incorrect because they do not address the critical nature of the client's condition. Contacting the healthcare provider, reassuring the wife, or waiting for symptoms to worsen could delay necessary medical intervention.

3. What preparation should be made for a client undergoing a KUB (Kidney, Ureter, Bladder) radiography test?

Correct Answer: No special orders are necessary for this examination

Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.

4. The nurse is preparing to administer an enteral feeding to a client via a nasogastric feeding tube. The most important action of the nurse is:

Correct Answer: Verify correct placement of the tube

Rationale: The most crucial action for the nurse when preparing to administer enteral feeding via a nasogastric tube is to verify the correct placement of the tube. Proper placement of the tube is vital to prevent complications such as aspiration into the lungs. The definitive methods to confirm the position of the nasogastric tube include visualization through an x-ray or aspirating stomach contents and checking their pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm placement in the stomach. Choice B, checking that the feeding solution matches the dietary order, is important for ensuring the correct nutrition is provided but is not as critical as verifying tube placement to prevent potential harm. Choice C, aspirating gastric contents to determine the amount of the last feeding remaining in the stomach, is a common nursing practice but is not the most crucial action when compared to ensuring correct tube placement. Choice D, ensuring that the feeding solution is at room temperature, is relevant for patient comfort and preventing thermal injury but is not as essential as confirming correct tube placement to prevent serious complications.

5. 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?

Correct Answer: Tall peaked “T” waves

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.
