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. A client presents with symptoms of a sore throat, swollen lymph nodes in the neck, fever, chills, and extreme fatigue. Based on these symptoms, which of the following illnesses could the nurse consider for this client?
- A. Methicillin-resistant Staphylococcus aureus (MRSA)
- B. Hepatitis B
- C. Infectious mononucleosis
- D. Norovirus infection
Correct answer: C
Rationale: Infectious mononucleosis is a viral disease caused by the Epstein-Barr virus. The symptoms of sore throat, fever, chills, swollen lymph nodes, and extreme fatigue are characteristic of infectious mononucleosis. The diagnosis is confirmed through the client's history and blood tests for the Epstein-Barr virus. Methicillin-resistant Staphylococcus aureus (MRSA) presents with localized skin infections, not the systemic symptoms described. Hepatitis B typically presents with jaundice, abdominal pain, and liver inflammation, not the symptoms described. Norovirus infection commonly causes gastrointestinal symptoms like vomiting and diarrhea, not the symptoms presented by the client.
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. Clinical manifestations of asthma include:
- A. Decreased expiratory time
- B. Increased peak expiratory flow
- C. Increased use of accessory muscles
- D. Increased oxygen saturation
Correct answer: C
Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.
5. A patient presents with vesicles covering the upper torso. Which of the following situations could cause this condition?
- A. Knife fight
- B. Auto accident
- C. Sunburn
- D. Fungal infection
Correct answer: C
Rationale: Vesicles are fluid-filled blisters. In the context of the upper torso, the presentation of vesicles suggests a second-degree sunburn. Sunburn can cause blistering, leading to the formation of vesicles. Choice A, 'Knife fight,' does not align with the presentation of vesicles on the upper torso due to trauma. Choice B, 'Auto accident,' is more likely to cause abrasions or bruises rather than vesicles. Choice D, 'Fungal infection,' typically presents with other symptoms such as redness, itching, or scaling, but not vesicles on the upper torso.
