NCLEX RN Exam Review Answers

1. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

A. Diarrhea and Vomiting
B. Dizziness and Drowsiness
C. Metallic taste
D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

2. Which entry in the medical record best meets the requirement for problem-oriented charting?

A. "A: Pacing and muttering to self. P: Sensory perceptual alteration, related to internal auditory stimulation. I: Given fluphenazine (Prolixin) 2.5 mg at 0900, and went to room to lie down. E: Calmer by 0930. Returned to lounge to watch TV."?
B. "S: States, 'I feel like I'm ready to blow up.' O: Pacing hall, mumbling to self. A: Auditory hallucinations. P: Offer haloperidol (Haldol) 2 mg . I: (Haldol) 2 mg at 0900. E: Returned to lounge at 0930 and quietly watched TV."?
C. "Agitated behavior. D: Patient muttering to self as though answering an unseen person. A: Given haloperidol (Haldol) 2 mg and went to room to lie down. E: Patient calmer. Returned to lounge to watch TV."?
D. "Pacing hall and muttering to self as though answering an unseen person. haloperidol (Haldol) 2 mg administered at 0900 with calming effect in 30 minutes. Stated, 'I'm no longer bothered by the voices.'"?

Correct answer: B

Rationale: Problem-oriented documentation uses the first letter of key words to organize data: S for subjective data, O for objective data, A for assessment, P for plan, I for intervention, and E for evaluation. The correct answer demonstrates problem-oriented charting by following this structure. Choice A, C, and D do not follow the problem-oriented charting format and instead offer examples of different documentation styles such as PIE charting, focus documentation, and narrative documentation, respectively. Therefore, choice B is the best example of problem-oriented charting among the options provided.

3. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

A. Surgical repair of a diseased coronary artery
B. Placement of an automatic internal cardiac defibrillator
C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

4. A 3-year-old child was brought to the pediatric clinic after the sudden onset of findings that include irritability, thick muffled voice, croaking on inspiration, being hot to the touch, sitting leaning forward, tongue protruding, drooling, and suprasternal retractions. What should the nurse do first?

A. Prepare the child for an X-ray of the upper airways
B. Examine the child's throat
C. Collect a sputum specimen
D. Notify the healthcare provider of the child's status

Correct answer: D

Rationale: The correct initial action is to notify the healthcare provider of the child's status. The presenting symptoms described, such as irritability, thick muffled voice, croaking on inspiration, being hot to the touch, sitting leaning forward, tongue protruding, drooling, and suprasternal retractions, are indicative of epiglottitis, a potentially life-threatening condition. Immediate medical attention is crucial in such cases. While preparing for an X-ray or examining the throat may be necessary, the priority is to ensure prompt evaluation and intervention by the healthcare provider. Collecting a sputum specimen is not relevant in this situation and would cause unnecessary delay. Therefore, the nurse should prioritize communication with the healthcare provider to expedite appropriate management and treatment.

5. The clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

A. Diarrhea
B. Projectile vomiting
C. Regurgitation of feedings
D. Foul-smelling, ribbon-like stools

Correct answer: D

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.
