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. 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. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?
- A. Diarrhea
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.
4. The nurse recognizes that teaching a 44-year-old woman following a laparoscopic cholecystectomy has been effective when the patient states which of the following?
- A. I can expect yellow-green drainage from the incision for a few days.
- B. I can remove the bandages on my incisions tomorrow and take a shower.
- C. I should plan to limit my activities and not return to work for 4 to 6 weeks.
- D. I will always need to maintain a low-fat diet since I no longer have a gallbladder.
Correct answer: B
Rationale: The correct answer is, 'I can remove the bandages on my incisions tomorrow and take a shower.' After a laparoscopic cholecystectomy, patients have Band-Aids over the incisions and can typically remove the bandages the next day. Patients are usually discharged the same or next day and have minimal restrictions on their daily activities. Yellow-green drainage from the incision would be abnormal, requiring the patient to contact their healthcare provider. While a low-fat diet may be recommended initially after surgery, it is not a lifelong requirement, as the body can adjust to the absence of the gallbladder over time. Choice A is incorrect as abnormal drainage should be reported. Choice C is incorrect as most patients can resume normal activities within a few days to a week. Choice D is incorrect as maintaining a low-fat diet is not a lifelong necessity after a cholecystectomy.
5. The nurse is preparing to administer an enteral feeding to a client via a nasogastric feeding tube. The most important action of the nurse is:
- A. Verify correct placement of the tube
- B. Check that the feeding solution matches the dietary order
- C. Aspirate gastric contents to determine the amount of the last feeding remaining in the stomach
- D. Ensure that the feeding solution is at room temperature
Correct answer: A
Rationale: The most crucial action for the nurse when preparing to administer enteral feeding via a nasogastric tube is to verify the correct placement of the tube. Proper placement of the tube is vital to prevent complications such as aspiration into the lungs. The definitive methods to confirm the position of the nasogastric tube include visualization through an x-ray or aspirating stomach contents and checking their pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm placement in the stomach. Choice B, checking that the feeding solution matches the dietary order, is important for ensuring the correct nutrition is provided but is not as critical as verifying tube placement to prevent potential harm. Choice C, aspirating gastric contents to determine the amount of the last feeding remaining in the stomach, is a common nursing practice but is not the most crucial action when compared to ensuring correct tube placement. Choice D, ensuring that the feeding solution is at room temperature, is relevant for patient comfort and preventing thermal injury but is not as essential as confirming correct tube placement to prevent serious complications.
