Question 1 of 5
A nurse is caring for a client with a diagnosis of tuberculosis (TB). What is the most important precaution for the nurse to take?
Correct Answer: C
Rationale: The correct answer is C: Using an N95 respirator while providing care. This is because TB is an airborne disease that can spread through respiratory droplets. The N95 respirator provides the highest level of protection against inhaling these droplets. A: Wearing a surgical mask is not sufficient to protect against TB transmission as it does not filter out small infectious particles. B: Hand hygiene is important for infection control but does not specifically address airborne transmission of TB. D: Gowning and gloving may be necessary for contact precautions but do not provide adequate protection against airborne transmission of TB.
Question 2 of 5
The nurse is caring for a client with cystic fibrosis. What intervention is most effective in improving airway clearance?
Correct Answer: B
Rationale: The correct answer is B: Performing chest physiotherapy regularly. Chest physiotherapy helps mobilize and clear mucus from the airways in cystic fibrosis patients, improving airway clearance. This intervention is essential in preventing respiratory complications. Administering bronchodilators before meals (A) may help with bronchodilation but does not directly address airway clearance. Providing a high-calorie, high-protein diet (C) is important for nutrition but does not specifically target airway clearance. Encouraging the use of a spacer with inhalers (D) may help with medication delivery but does not directly improve airway clearance like chest physiotherapy.
Question 3 of 5
The nurse is teaching a client with asthma about identifying triggers. Which trigger is most commonly associated with asthma attacks?
Correct Answer: A
Rationale: The correct answer is A: Cold air. Cold air is a common trigger for asthma attacks as it can cause airways to constrict and become inflamed, leading to difficulty breathing. Cold air can also worsen existing asthma symptoms. Loud noises (B), lack of sleep (C), and physical inactivity (D) are not typically associated with triggering asthma attacks. Loud noises may exacerbate stress but do not directly trigger asthma. Lack of sleep and physical inactivity can impact overall health but are not primary triggers for asthma attacks.
Question 4 of 5
A client with tuberculosis (TB) is prescribed rifampin. Which side effect should the nurse include in client education?
Correct Answer: A
Rationale: The correct answer is A: Orange discoloration of urine and tears. Rifampin is known to cause harmless orange discoloration of bodily fluids, including urine and tears. This is important for the client to be aware of to prevent unnecessary concern. B: Increased risk of photosensitivity is not a common side effect of rifampin. C: Frequent urination is not a typical side effect of rifampin. D: Sudden weight gain is not a known side effect of rifampin. In conclusion, the correct answer is A because it aligns with a known side effect of rifampin, while the other options are not associated with this medication.
Question 5 of 5
The nurse completes a shift assessment on a patient admitted in the early phase of heart failure. When auscultating the patient's lungs, which finding would the nurse most likely hear?
Correct Answer: C
Rationale: The correct answer is C: Discontinuous, high-pitched sounds of short duration during inspiration. In heart failure, the patient may develop pulmonary edema leading to crackles or fine rales on auscultation, which are best heard during inspiration due to the opening of collapsed alveoli. This is characterized by short-duration, high-pitched sounds. Option A is more indicative of rhonchi, commonly heard in conditions like bronchitis. Option B describes wheezes typically found in asthma or COPD. Option D describes coarse crackles, which are heard in conditions like pneumonia. Therefore, the most likely finding in a patient with early heart failure would be discontinuous, high-pitched sounds during inspiration.
