NCLEX RN Prioritization Questions

1. A patient is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?

A. Chest x-ray shows no upper lobe infiltrates.
B. TB medications have been taken for 6 months.
C. Mantoux testing shows an induration of 10 mm.
D. Three sputum smears for acid-fast bacilli are negative.

Correct answer: D

Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.

2. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?

A. IgA
B. IgD
C. IgE
D. IgG

Correct answer: D

Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.

3. When admitting a 64-year-old patient with acute pancreatitis, the healthcare provider should specifically inquire about a history of

A. diabetes mellitus.
B. high-protein diet.
C. cigarette smoking.
D. alcohol consumption.

Correct answer: D

Rationale: In patients with acute pancreatitis, alcohol consumption is a significant risk factor and one of the most common causes in the United States. It is crucial to assess alcohol intake as it plays a key role in the development of pancreatitis. While cigarette smoking, diabetes mellitus, and high-protein diets can contribute to various health issues, they are not directly associated with the development of acute pancreatitis.

4. Which of the following clients is most appropriate for receiving telemetry?

A. A client with syncope potentially related to cardiac dysrhythmia
B. A client with unstable angina
C. A client with sinus rhythm and PVCs
D. A client who had a myocardial infarction 6 hours ago

Correct answer: A

Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.

5. 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.
