Question 1 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 2 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 3 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.
Question 4 of 5
A nurse is caring for a patient with severe burns. What is the priority intervention?
Correct Answer: C
Rationale: The correct answer is C: Provide sedation. This is the priority intervention for a patient with severe burns to manage pain and anxiety, prevent shock, and facilitate wound care. Sedation helps to reduce the patient's distress and allows for better assessment and treatment. Administering IV fluids (B) is important but not the top priority. Providing pain relief (A) is crucial, but sedation may be more effective for severe burns. Administering an antiemetic (D) is not the priority unless the patient is actively vomiting.
Question 5 of 5
A nurse is caring for a patient who is receiving mechanical ventilation. The patient is showing signs of respiratory distress. What is the priority intervention?
Correct Answer: B
Rationale: The priority intervention in this scenario is to administer a nebulized bronchodilator (Choice B). This is because the patient is showing signs of respiratory distress, indicating a need for immediate bronchodilation to improve airway patency and ventilation. Checking the ventilator settings (Choice A) is important but not the priority when the patient is in distress. Administering bronchodilator therapy (Choice C) is similar to Choice B but is less specific and may not be as immediate. Administering insulin (Choice D) is not relevant in this situation since the patient's respiratory distress is the primary concern.
