When preparing to administer a medication through a nasogastric (NG) tube, what is the first action the nurse should take?

Correct Answer: A

Rationale: The correct first action when preparing to administer a medication through a nasogastric (NG) tube is to check the placement of the NG tube. This step is essential to ensure that the tube is correctly positioned in the stomach and not in the lungs, preventing potential complications. Flushing the tube with saline may be required, but it should follow the verification of tube placement. Positioning the client in a semi-Fowler's position is necessary for comfort during the procedure but is not the initial step. Administering the medication can only be done safely after confirming the correct placement of the NG tube.

Correct Answer: C

Rationale: When caring for a patient with a newly inserted tracheostomy, the priority is to monitor for signs of infection and ensure a patent airway. This is crucial to prevent complications such as airway obstruction or infection. While keeping the tracheostomy tube clean and dry is important for overall care, it is not the highest priority when compared to ensuring a patent airway. Providing regular oral hygiene is essential for the patient's comfort but takes a secondary role to maintaining airway patency. Encouraging the patient to cough and deep breathe may be beneficial but is not as critical as monitoring for infection and keeping the airway clear.

Correct Answer: C

Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.

Correct Answer: A

Rationale: The correct answer is A: To prevent deep vein thrombosis (DVT). Sequential compression devices (SCDs) are used postoperatively to prevent DVT by promoting blood circulation in the legs. This helps reduce the risk of blood clots forming in the deep veins of the legs. Choice B, to promote wound healing, is incorrect as SCDs are primarily used for circulatory purposes rather than wound healing. Choice C, to reduce postoperative pain, is incorrect as the primary purpose of SCDs is not pain management but rather prevention of DVT. Choice D, to maintain body temperature, is incorrect as SCDs are not designed for regulating body temperature but for preventing circulatory issues.

Correct Answer: B

Rationale: Administering a beta-blocker intravenously is the correct intervention for a patient experiencing a hypertensive crisis. Beta-blockers help quickly reduce blood pressure and prevent complications such as stroke or heart attack. Placing the patient in a supine position can worsen the condition by reducing venous return and increasing the workload of the heart. Encouraging the patient to drink fluids is not recommended as it can exacerbate hypertension by increasing fluid volume. Applying a cold compress to the forehead does not address the underlying cause of the hypertensive crisis and is unlikely to provide significant benefit.
