Correct Answer: B

Rationale: The correct answer is B: Toast with jelly. Tetracycline can cause gastrointestinal upset when taken with dairy products. Yogurt with fruit (Choice A) contains dairy, which can worsen the gastrointestinal upset. Crackers with peanut butter (Choice C) and oatmeal with raisins (Choice D) are also not the best choices as they may not be gentle enough on the stomach. Toast with jelly is a simple snack that does not contain dairy and is less likely to exacerbate the gastrointestinal upset.

Correct Answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

Correct Answer: C

Rationale: When a client on heparin reports tarry stools, it can be indicative of gastrointestinal bleeding. The correct action for the nurse is to monitor the stools for blood and review the Partial Thromboplastin Time (PTT) results. This is essential to detect any potential bleeding complications associated with heparin therapy. Option A is incorrect because warfarin is not the immediate intervention for tarry stools in a client on heparin. Option B is irrelevant to the situation described. Option D is incorrect as Vitamin K is the antidote for warfarin, not heparin.

Correct Answer: D

Rationale: Controlling blood pressure is critical in managing peripheral vascular disease, as elevated pressure can exacerbate vascular damage and complications. While foot care, shoe fit, and exercise are important, lowering blood pressure is a primary goal. Proper blood pressure management helps in preventing further damage to the blood vessels and reduces the risk of complications associated with peripheral vascular disease, making it the most crucial outcome to include in the plan of care for this client.

Correct Answer: A

Rationale: The correct answer is to administer a nebulizer treatment of albuterol. In acute bronchospasm, the priority intervention is to deliver a bronchodilator like albuterol to open the airways and improve breathing. Starting an IV infusion of normal saline (Choice B) may be necessary but not the priority in this situation. Administering oxygen at 4L/min via nasal cannula (Choice C) is important but not the first intervention for bronchospasm. Positioning the client in a high Fowler's position (Choice D) can help with breathing but is not the priority over administering a bronchodilator.
