Respiratory NCLEX Practice Questions
Answers and Rationale

71) B
- Before weaning a client from mechanical ventilation, it's most important to have a baseline ABG levels. During the weaning process, ABG levels will be checked to assess how the client is tolerating the procedure. Other assessment parameters are less critical. Measuring fluid volume intake and output is always important when a client is being mechanically ventilated. Prior attempts at weaning and ECG results are documented on the client's record, and the nurse can refer to them before the weaning process begins.

72) A
- A 10-mm induration strongly suggests a positive response in this tuberculosis screening test; a 15-mm induration clearly requires further evaluation. The other options aren't positive reactions to the test and require no further evaluation.

73) A
- The client's signs and symptoms suggest pulmonary embolism. therefore, maintaining respiratory function takes priority. The nurse should first initiate oxygen therapy and then notify the physician immediately. The physician will most likely prescribe an anticoagulant, such as heparin, or an antithrombolytic to dissolve the thrombus. Analgesics can be administered to decrease pain and anxiety but administering oxygen takes priority. Suctioning typically isn't necessary with pulmonary embolism.

74) B
- This response is most therapeutic because it encourages the client to express feelings and concerns. Options A and D offer false hope and reflect the nurse's empirical observations, not statistics. Option C is inappropriate because an informed person who isn't a member of the health care team should discuss (at the client's request) which level of care the client wishes to receive in case of an emergency.

75) C
- Inspiratory and expiratory stridor is a low-pitched crowing sound heard in client who have a foreign body obstructing the trachea or mainstem bronchi. Acute asthmatic attacks are characterized by wheezing. Goiter attacks and severe laryngotracheitis are associated with inspiratory  stridor only.
