NCLEX RN Exam Questions
1. While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?
- A. Stop the saline infusion immediately
- B. Notify the physician
- C. Elevate the patient's legs
- D. Continue the infusion, as these findings are normal
Correct answer: A
Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
2. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?
- A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
- B. "Strawberry tongue"? is a characteristic sign.
- C. Petechiae occur on the soft palate.
- D. The pharynx is red and swollen.
Correct answer: C
Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.
3. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?
- A. The absence of special cells in the rectum caused the disease.
- B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
- C. The disease does not occur due to increased bowel motility leading to spasm and pain.
- D. The disease is not caused by the inability to tolerate sugar found in dairy products.
Correct answer: A
Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.
4. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
- A. Hemoglobin of 11 g/dl
- B. Platelet count of 150,000
- C. INR of 2.5
- D. Potassium of 2.7 mEq/L
Correct answer: D
Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
5. A patient is found unconscious in their room with rhythmic jerking of all four extremities and heavy foaming at the mouth. The patient was on seizure precautions with bedrails up and padded. What is the priority action for the nurse to take?
- A. Administer Lorazepam (Ativan)
- B. Turn the patient to his/her side
- C. Call the physician
- D. Suction the patient
Correct answer: B
Rationale: The nurse's priority action should be to turn the patient to his/her side. This position helps maintain an open airway and prevents aspiration of secretions or vomitus. Administering Lorazepam (Ativan) without ensuring a clear airway could lead to further complications. Calling the physician is important, but immediate interventions to protect the airway take precedence. Suctioning the patient may be necessary but should not be the initial action; positioning for airway protection is the priority.
