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. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:
- A. Assist the client in using the bedside commode.
- B. Administer stool softeners daily as prescribed.
- C. Administer antidysrhythmics prn as ordered.
- D. Maintain the client on strict bed rest.
Correct answer: B
Rationale: Administering stool softeners daily is crucial to prevent straining during defecation, which can lead to the Valsalva maneuver. Straining can increase intrathoracic pressure, decrease venous return to the heart, and reduce cardiac output, potentially worsening the client's condition. If constipation occurs, the use of laxatives may be necessary to avoid straining. Administering antidysrhythmics on an as-needed basis is not indicated for preventing the Valsalva maneuver; they are used to manage dysrhythmias. Strict bed rest is not necessary and may lead to complications such as deconditioning, DVT, and respiratory issues in the absence of specific medical indications.
3. How does shock typically progress?
- A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
- B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
- C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
- D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours
Correct answer: A
Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.
4. The nurse is caring for a 27-year-old female client with a venous stasis ulcer. Which nursing intervention would be most effective in promoting healing?
- A. Apply dressing using sterile technique
- B. Improve the client's nutrition status
- C. Initiate limb compression therapy
- D. Begin proteolytic debridement
Correct answer: B
Rationale: Venous stasis occurs when venous blood collects and stagnates in the lower leg due to incompetent venous valves. This leads to inadequate oxygen and nutrient supply to the cells in the lower extremities, resulting in cell death or necrosis. Venous stasis ulcers, characterized by shallow brown wounds with irregular margins, typically develop on the lower leg or ankle. The primary goal in managing clients with venous stasis ulcers is to promote healing. Proper nutrition plays a crucial role in wound healing. Nutritional deficiencies are common causes of venous ulcers, and a diet rich in protein, iron, zinc, and vitamins C and A is recommended to enhance wound healing. Applying dressings with sterile technique, initiating limb compression therapy, and beginning proteolytic debridement are important interventions in wound care but may not directly address the underlying issue of poor nutrition that is essential for healing venous stasis ulcers.
5. After hydrostatic reduction for intussusception, what client response should the nurse expect to observe?
- A. Abdominal distension
- B. Currant jelly-like stools
- C. Severe, colicky-type pain with vomiting
- D. Passage of barium or water-soluble contrast with stools
Correct answer: D
Rationale: After hydrostatic reduction for intussusception, the nurse should observe the passage of barium or water-soluble contrast with stools. This indicates a successful reduction of the telescoped bowel segment. Abdominal distension and currant jelly-like stools are clinical manifestations of intussusception, not expected outcomes following hydrostatic reduction. Severe, colicky-type pain with vomiting suggests an unresolved gastrointestinal issue, not a successful reduction of intussusception.
