Correct Answer: B

Rationale: Salmeterol is classified as a long-acting beta2-agonist, which is used to prevent asthma attacks by providing extended bronchodilation. It is not typically used for immediate relief of acute bronchospasm or for suppressing cough. Additionally, salmeterol does not have the primary purpose of thinning respiratory secretions.

Correct Answer: B

Rationale: Ipratropium is an anticholinergic bronchodilator that primarily works to relieve bronchospasm by dilating the airways and improving airflow in patients with COPD. It does not have a significant effect on reducing inflammation, suppressing cough, or thinning respiratory secretions.

Correct Answer: A

Rationale: Gabapentin is primarily prescribed to relieve neuropathic pain. It works by stabilizing electrical activity in the nerves, making it effective in managing conditions such as diabetic neuropathy, postherpetic neuralgia, and other forms of chronic pain originating from nerve damage.

Correct Answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

Correct Answer: C

Rationale: When educating a patient prescribed ceftriaxone for bacterial pneumonia, it is crucial to emphasize completing the full course of the antibiotic. Completing the full course helps ensure the infection is completely eradicated and reduces the risk of antibiotic resistance. Incomplete courses of antibiotics can lead to treatment failure and the development of resistant bacterial strains. Therefore, it is essential for patients to adhere to the prescribed treatment regimen to achieve optimal outcomes.
