NCLEX RN Practice Questions Quizlet
1. 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.
2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?
- A. Venturi mask
- B. Partial rebreather mask
- C. Non-rebreather mask
- D. Simple face mask
Correct answer: C
Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
3. In which order should the nurse take the following actions for an older patient with new onset confusion who is normally alert and oriented?
- A. Obtain the oxygen saturation, Check the patient's pulse rate, Notify the health care provider, Document the change in status
- B. Obtain the oxygen saturation, Check the patient's pulse rate, Document the change in status, Notify the health care provider
- C. Document the change in status, Notify the health care provider, Check the patient's pulse rate, Obtain the oxygen saturation
- D. Document the change in status, Check the patient's pulse rate, Obtain the oxygen saturation, Notify the health care provider
Correct answer: B
Rationale: The correct order of actions for the nurse in this scenario is to first obtain the oxygen saturation to assess the patient's airway and oxygenation status. Next, checking the patient's pulse rate helps in evaluating circulation. Subsequently, documenting the change in the patient's status is important for maintaining an accurate record of care. Finally, notifying the health care provider is crucial to ensure timely intervention and further management. Choices A, C, and D are incorrect because assessing oxygen saturation should precede checking the pulse rate to address potential physiological causes of confusion. Additionally, documentation should follow patient assessment and notification of the healthcare provider for appropriate record-keeping and communication.
4. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?
- A. The medication will reduce the risk of aspiration.
- B. The medication will inhibit the development of gastric ulcers.
- C. The medication will prevent irritation of the enlarged veins.
- D. The medication will decrease nausea and improve appetite.
Correct answer: C
Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.
5. A 49-year-old patient with multiple sclerosis (MS) is to begin treatment with glatiramer acetate (Copaxone). Which information will the nurse include in patient teaching?
- A. Recommendation to drink at least 4 L of fluid daily
- B. Need to avoid driving or operating heavy machinery
- C. How to draw up and administer injections of the medication
- D. Use of contraceptive methods other than oral contraceptives
Correct answer: C
Rationale: When initiating treatment with glatiramer acetate (Copaxone), patient education should focus on teaching the patient how to draw up and administer injections of the medication. Copaxone is administered via self-injection, hence understanding the correct technique is crucial for successful treatment. Recommendations regarding fluid intake or the need to avoid driving heavy machinery are not directly related to glatiramer acetate therapy. Additionally, while discussing contraceptive methods may be important, the use of oral contraceptives does not specifically contraindicate the use of glatiramer acetate.
