The charge nurse observes that a client with a nasogastric tube on low intermittent suction is drinking a glass of water immediately after the unlicensed assistive personnel (UAP) left the room. What action should the nurse take?

Correct Answer: A

Rationale: The correct answer is A: Remove the glass of water and speak to the UAP. The rationale is as follows: 1) Drinking water with low intermittent suction can cause complications. 2) Immediate action is necessary to prevent harm. 3) Speaking to the UAP clarifies the situation and provides education. 4) Removing the glass of water ensures the client's safety. Incorrect choices: B: Discussing at the end of the day delays action and puts the client at risk. C: Writing an incident report is important, but immediate intervention is needed first. D: Reminding the client of electrolyte imbalance does not address the current issue of drinking water with a nasogastric tube.

Correct Answer: C

Rationale: The correct answer is C: Take the medication with a full glass of water. Alendronate should be taken with a full glass of water on an empty stomach in the morning to enhance absorption. Option A is incorrect because taking alendronate with milk decreases its absorption. Option B is incorrect as lying down after taking alendronate can lead to esophageal irritation. Option D is incorrect because taking the medication before bedtime can cause esophageal irritation as well due to the risk of reflux when lying down.

Correct Answer: A

Rationale: The correct answer is A: Reduce intraocular pressure. Timolol is a beta-blocker that works by decreasing the production of aqueous humor in the eye, thereby reducing intraocular pressure. This action helps to prevent damage to the optic nerve in patients with glaucoma. Choices B and C are incorrect because timolol does not affect pupil size. Choice D is incorrect because timolol does not enhance tear production; in fact, it may have a drying effect on the eyes.

Correct Answer: B

Rationale: The correct answer is B: Relieve bronchospasm. Tiotropium is an anticholinergic medication that acts by relaxing the muscles around the airways, thereby helping to relieve bronchospasm in patients with COPD. This results in improved airflow and reduced shortness of breath. A: Reduce mucus production - This is incorrect as tiotropium does not directly affect mucus production but rather focuses on bronchospasm relief. C: Suppress cough - Tiotropium may help with cough associated with COPD by improving airflow, but its primary purpose is not to suppress cough. D: Thin respiratory secretions - Tiotropium does not have a direct effect on thinning respiratory secretions; its main action is bronchodilation to relieve bronchospasm in COPD.

Correct Answer: C

Rationale: Rationale: 1. Enoxaparin is a low molecular weight heparin that primarily affects the intrinsic pathway of coagulation. 2. INR is used to monitor the effectiveness of anticoagulants affecting the intrinsic pathway. 3. Monitoring INR helps ensure the patient is within the therapeutic range to prevent clotting without excessive bleeding. 4. PT and PTT primarily evaluate the extrinsic and intrinsic pathways, respectively, not specific to enoxaparin. 5. Platelet count is not directly related to monitoring the effectiveness of enoxaparin in treating DVT.
