Question 1 of 5
The nurse teaches a patient about using a dry powder inhaler. Which statement indicates effective learning?
Correct Answer: B
Rationale: The correct answer is B because inhaling quickly and deeply ensures effective delivery of the medication to the lungs. This allows for optimal absorption and therapeutic effect. Shaking the inhaler (Choice A) is unnecessary and may cause the medication to clump. Attaching a spacer (Choice C) is typically not required for dry powder inhalers. Exhaling forcefully (Choice D) may reduce the amount of medication reaching the lungs.
Question 2 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 3 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 4 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.
Question 5 of 5
A nurse is caring for a postoperative patient who is having difficulty breathing. Which is the priority nursing intervention?
Correct Answer: B
Rationale: The correct answer is B: Administer oxygen. This is the priority intervention because the patient is having difficulty breathing, indicating possible respiratory distress. Administering oxygen will help improve oxygenation and support the patient's respiratory function. Checking vital signs is important but addressing the breathing difficulty takes precedence. Administering pain medication or a sedative is not appropriate without addressing the underlying cause of respiratory distress. Oxygen therapy should be initiated promptly to ensure the patient's safety and well-being.
