Exam Cram NCLEX RN Practice Questions
1. While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?
- A. 70-80 mmHg
- B. 100-120 mmHg
- C. 150-170 mmHg
- D. 200 mmHg
Correct answer: B
Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
2. What is the most common complication of chest wall injury?
- A. Hemothorax
- B. Atelectasis
- C. Pneumonia
- D. Pneumothorax
Correct answer: C
Rationale: Pneumonia is the most common complication of chest wall injury. Chest wall trauma can lead to impaired lung function, making patients more susceptible to pneumonia due to reduced ability to clear secretions and impaired breathing. While hemothorax and pneumothorax are potential complications of chest wall injury, pneumonia is more commonly encountered. Atelectasis, although a common pulmonary complication, is not typically the most common complication seen in chest wall injuries.
3. The clinic nurse is assessing jaundice in a child with hepatitis. Which anatomical area would provide the best data regarding the presence of jaundice?
- A. The nail beds.
- B. The skin in the sacral area.
- C. The skin in the abdominal area.
- D. The membranes in the ear canal.
Correct answer: A
Rationale: Jaundice, if present, can be best assessed in areas such as the sclera, nail beds, and mucous membranes due to the yellowing of these tissues. The nail beds specifically provide a good indication of jaundice. The skin in the sacral area (Option B) is not typically the best area for assessing jaundice as it is less visible and not as reliable as the nail beds. The skin in the abdominal area (Option C) may show generalized jaundice, but the nail beds are more specific for detecting early signs. Lastly, assessing the membranes in the ear canal (Option D) is not a standard method for evaluating jaundice; the sclera and nail beds are more commonly used for this purpose.
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. 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 prescribed
- D. Maintain the client on strict bed rest
Correct answer: B
Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.
