Question 1 of 5
A nurse is teaching a patient with asthma about using a peak flow meter. Which statement requires correction?
Correct Answer: C
Rationale: The correct answer is C because using the peak flow meter during an asthma attack is incorrect. Peak flow measurements should be taken when the patient is stable and not experiencing an asthma exacerbation. This is because peak flow readings during an attack may not accurately reflect the patient's baseline lung function. Choices A, B, and D are correct because exhaling forcefully, recording the highest of three readings, and measuring peak flow at the same time daily are all appropriate techniques for using a peak flow meter to monitor asthma control.
Question 2 of 5
Which patient is at highest risk for developing a pulmonary embolism (PE)?
Correct Answer: B
Rationale: The correct answer is B. Patients on bed rest after hip surgery are at the highest risk for developing a pulmonary embolism (PE) due to immobilization and venous stasis, which can lead to blood clots forming in the legs that can travel to the lungs. Choice A is less likely as antibiotics can help treat pneumonia and reduce the risk of PE. Choice C is less likely as asthma and allergies do not directly increase the risk of PE. Choice D is less likely as COPD patients using supplemental oxygen are typically monitored closely and managed to reduce the risk of PE.
Question 3 of 5
The nurse reviews arterial blood gas (ABG) results for a patient with respiratory distress: pH 7.28, PaCO2 55 mm Hg, HCO3- 24 mEq/L. How should the results be interpreted?
Correct Answer: B
Rationale: The correct answer is B: Uncompensated respiratory acidosis. The low pH (acidosis) along with high PaCO2 (respiratory component) indicates primary respiratory acidosis. The HCO3- level is within normal range, ruling out metabolic compensation. There is no evidence of alkalosis. Therefore, the ABG results suggest uncompensated respiratory acidosis. Choices A, C, and D are incorrect as they do not align with the presented ABG values and interpretation.
Question 4 of 5
A nurse assesses a patient with newly diagnosed lung cancer. The patient expresses fear about the future. What is the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D because it shows empathy and encourages the patient to express their feelings. By asking the patient to elaborate on their emotions, the nurse can better understand their concerns and provide appropriate support. Choice A is too direct and may not be well-received by the patient. Choice B dismisses the patient's emotional needs. Choice C may provide false reassurance and overlook the patient's current emotional state.
Question 5 of 5
The nurse is listening to the client's breath sounds and hears a creaking, grating sound on inspiration and expiration over the posterior right lower lobe. How would the nurse correctly document this on the client's record?
Correct Answer: D
Rationale: The correct answer is D: Pleural friction rub. This sound is caused by inflamed pleural surfaces rubbing together during inspiration and expiration. The creaking, grating quality is characteristic of a pleural friction rub. Wheezes (A) are high-pitched musical sounds, crackles (B) are fine, crackling sounds, and rhonchi (C) are low-pitched, snoring sounds. These do not match the description given in the question.
