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 patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?
- A. Ask the patient to lie down to complete a full physical assessment.
- B. Briefly ask specific questions about this episode of respiratory distress.
- C. Complete the admission database to check for allergies before treatment.
- D. Delay the physical assessment to first complete pulmonary function tests.
Correct answer: B
Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.
3. The parents of a child with a hernia are instructed by the nurse on measures to reduce the hernia. Which statement indicates the parents understand the care for their child?
- A. We will encourage our child to cough every few hours on a daily basis.
- B. We will make sure that our child participates in physical activity every day.
- C. We will provide comfort measures to reduce any crying periods by our child.
- D. We will be sure to give our child a Fleet enema every day to prevent constipation.
Correct answer: C
Rationale: The correct answer is providing comfort measures to reduce any crying periods by the child. This can include offering a warm bath, avoiding upright positioning, and using other comfort measures to reduce crying, which can help reduce a hernia. Encouraging coughing or physical activity can increase strain on the hernia. Giving a Fleet enema daily for constipation is not recommended as it can also increase strain on the hernia.
4. 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.
5. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:
- A. It results when oxygen demand is greater than oxygen supply.
- B. It is characterized by pain that often occurs during rest.
- C. It is a result of tissue hypoxia.
- D. It is characterized by cramping and weakness.
Correct answer: D
Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.
