Correct Answer: D

Rationale: When suctioning a tracheostomy tube, it is essential to insert the suction catheter into the trachea and apply intermittent suction with removal of the catheter. This technique helps prevent damage to the trachea and reduces discomfort for the client. Choice A is incorrect because increasing wall suction with the removal of the suction catheter can cause trauma to the tracheal mucosa. Choice B is incorrect because instilling saline into the tracheostomy tube before suctioning is not recommended as it can lead to complications. Choice C is incorrect as oropharyngeal suctioning should be done before tracheal suctioning to prevent the risk of aspiration.

Correct Answer: D

Rationale: The best schedule for administering the IV antibiotic in 4 divided doses is 0800, 1200, 1600, and 2000. This timing allows for equal spacing between doses, ensuring consistent therapeutic levels of the medication in the client's system. Choice A provides doses too close together, increasing the risk of medication errors and potential toxicity. Choice B's suggestion of giving doses during waking hours is vague and lacks specific timing, which may result in irregular dosing intervals. Choice C, administering with meals and a bedtime snack, is unrelated to the timing of the antibiotic doses and does not optimize the drug's effectiveness.

Correct Answer: B

Rationale: The most crucial finding to report to the healthcare provider in this scenario is a serum potassium level of 3.1 mEq/L. Hypokalemia can lead to serious complications, including cardiac issues. Gastric output, increased BUN, and monitoring the 24-hour intake are essential but do not pose an immediate risk as hypokalemia does in this situation.

Correct Answer: A

Rationale: When an auscultatory gap is present, comparing the palpated systolic blood pressure with the auscultated pressure is crucial. This helps to accurately measure blood pressure and detect any discrepancies caused by the gap. Assessing for lightheadedness upon standing (choice B) is unrelated to addressing an auscultatory gap. Checking the consistency between automated and manual blood pressure readings (choice C) is important for validation but not specifically for managing an auscultatory gap. Observing blood pressure changes between lying and sitting positions (choice D) is relevant for orthostatic hypotension assessment but not for dealing with an auscultatory gap.
