Question 1 of 5
What method can be used to identify a virus?
Correct Answer: D
Rationale: Serological testing (e.g., antibody detection) identifies viruses, unlike staining or antibiotic tests suited for bacteria.
Question 2 of 5
Which of the following statements accurately describe a step for inserting an oropharyngeal airway? Select one that doesn't apply.
Correct Answer: C
Rationale: Correct steps include sizing the airway, measuring to the jaw angle, opening the mouth, and inserting with the tip up, then rotating 180° (not 360°).
Question 3 of 5
The nurse would expect to see increased ventilations if a patient exhibits
Correct Answer: B
Rationale: The correct answer is B: Decreased carbon dioxide levels. When carbon dioxide levels decrease in the body, it signals the need for increased ventilation to remove excess carbon dioxide. This is known as the respiratory drive. Increased oxygen saturation (choice A) would not directly trigger increased ventilations. Decreased pH (choice C) is a sign of acidosis and may lead to increased respiratory rate, but the primary trigger for ventilation is the carbon dioxide levels. Increased hemoglobin levels (choice D) would not directly influence the need for increased ventilations.
Question 4 of 5
The nurse is assessing a patient with a right pneumothorax. Which finding would the nurse expect?
Correct Answer: B
Rationale: The correct answer is B: Absence of breath sounds on the right side. In a right pneumothorax, air enters the pleural space, causing lung collapse and decreased breath sounds on the affected side. This is due to the lack of air movement in the affected lung area. Choices A, C, and D are incorrect because bilateral crackles and right-sided wheezes are not typically associated with pneumothorax. The trachea deviates away from the affected side in a tension pneumothorax, not necessarily in a simple pneumothorax.
Question 5 of 5
A nurse is teaching a client about the purpose of pursed-lip breathing. Which of the following explanations should the nurse provide?
Correct Answer: D
Rationale: The correct answer is D: To improve carbon dioxide elimination. Pursed-lip breathing involves exhaling through pursed lips to create back pressure, helping to keep airways open longer and improving carbon dioxide elimination. This technique reduces the work of breathing and can be beneficial for clients with chronic obstructive pulmonary disease (COPD) or other respiratory conditions. Explanation for other choices: A: To increase oxygen intake - Pursed-lip breathing primarily helps with exhaling, not increasing oxygen intake. B: To promote relaxation - While pursed-lip breathing can promote relaxation by slowing down breathing and reducing anxiety, its primary purpose is related to respiratory function. C: To strengthen respiratory muscles - Pursed-lip breathing mainly focuses on improving breathing efficiency rather than strengthening respiratory muscles.
