Nokea
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.

After a bronchoscopy, what is the most appropriate intervention for a patient with a chronic cough?
- A. Elevate the head of the bed to 80 to 90 degrees.
- B. Keep the patient NPO until the gag reflex returns.
- C. Place the patient on bed rest for at least 4 hours after bronchoscopy.
- D. Notify the health care provider about blood-tinged mucus.
Correct Answer: B
Rationale: The correct intervention is to keep the patient NPO until the gag reflex returns after a bronchoscopy. This is important because a local anesthetic is used during the procedure to suppress the gag and cough reflexes. Monitoring the return of these reflexes helps prevent the risk of aspiration and ensures the patient can safely resume oral intake. While blood-tinged mucus can occur after bronchoscopy, it is a common occurrence and not a cause for immediate concern. Placing the patient on bed rest for an extended period is unnecessary, and elevating the head of the bed to a high-Fowler's position is not specifically required post-bronchoscopy.
A patient experiences a chest wall contusion as a result of being struck in the chest with a baseball bat. The emergency department nurse would be most concerned if which finding is observed during the initial assessment?
- A. Paradoxic chest movement
- B. Complaint of chest wall pain
- C. Heart rate of 110 beats/minute
- D. Large bruised area on the chest
Correct Answer: A
Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.
A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?
- A. Administer 2 ventilations
- B. Perform a head-tilt, chin lift to open the airway
- C. Begin chest compressions
- D. Perform a jaw thrust to open the airway
Correct Answer: C
Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.
When obtaining a health history and physical assessment for a 36-year-old female patient with possible multiple sclerosis (MS), the nurse should
- A. assess for the presence of chest pain.
- B. inquire about urinary tract problems.
- C. inspect the skin for rashes or discoloration.
- D. ask the patient about any increase in libido.
Correct Answer: B
Rationale: When assessing a patient for possible multiple sclerosis (MS), it is important to inquire about urinary tract problems as they are common symptoms of the condition, such as incontinence or retention. Chest pain is not typically associated with MS, so assessing for its presence is not a priority. Inspecting the skin for rashes or discoloration is not a typical manifestation of MS. Additionally, a decrease in libido, rather than an increase, is more commonly seen in patients with MS. Therefore, the most appropriate action for the nurse in this scenario is to inquire about urinary tract problems.
A nurse is caring for a patient with peripheral vascular disease (PVD). The patient complains of burning and tingling of the hands and feet and cannot tolerate touch of any kind. Which of the following is the most likely explanation for these symptoms?
- A. Inadequate tissue perfusion leading to nerve damage.
- B. Fluid overload leading to compression of nerve tissue.
- C. Sensation distortion due to psychiatric disturbance.
- D. Inflammation of the skin on the hands and feet.
Correct Answer: A
Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest pain often is exacerbated by poor cardiac output. The condition is often partially or fully relieved by placing the extremity in a dependent position, so that perfusion is enhanced by the effects of gravity.
