A client with a history of urinary tract infections (UTIs) is being cared for by a nurse. Which of the following instructions should the nurse provide to prevent future infections?

Correct Answer: B

Rationale: The correct answer is to advise the client to drink 2-3 liters of water per day. Adequate hydration helps flush bacteria from the urinary tract, reducing the risk of UTIs. Choice A is incorrect because wiping from front to back is the appropriate technique to prevent the spread of bacteria from the rectal area to the urethra. Choice C is incorrect as holding urine for long periods can contribute to UTIs by allowing bacteria to grow in the bladder. Choice D is incorrect as wearing loose-fitting underwear is recommended to allow air circulation and prevent moisture buildup, reducing the risk of UTIs.

Correct Answer: B

Rationale: The correct answer is to take the medication with a full glass of water. Alendronate should be taken with a full glass of water to prevent esophageal irritation. Additionally, the client should remain upright for 30 minutes after taking it to prevent potential adverse effects. Choice A is incorrect because alendronate should not be taken at bedtime, but rather in the morning on an empty stomach. Choice C is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because the client should remain upright, not lie down, for 30 minutes after taking the medication.

Correct Answer: B

Rationale: The correct recommendation to reduce the risk of coronary artery disease is to exercise for at least 150 minutes per week. Regular exercise is crucial in maintaining cardiovascular health and reducing the chances of developing heart disease. Increasing intake of saturated fats (Choice A) is counterproductive as it can raise cholesterol levels and contribute to arterial plaque formation. Taking iron supplements daily (Choice C) is not directly related to reducing the risk of coronary artery disease. Limiting fruits and vegetables in the diet (Choice D) is also not advisable, as they are essential components of a heart-healthy diet due to their high fiber and nutrient content.

Correct Answer: C

Rationale: Elevating the affected leg is a crucial intervention in the care of a client with deep vein thrombosis (DVT). This position helps reduce swelling and promotes venous return, which can alleviate symptoms associated with DVT. Applying ice packs (Choice A) may worsen the condition by causing vasoconstriction. Encouraging ambulation (Choice B) can dislodge the clot and lead to fatal complications. Massaging the affected area (Choice D) can also dislodge the clot and is contraindicated in DVT.

Correct Answer: C

Rationale: The correct instruction is to take levothyroxine on an empty stomach. This is necessary for proper absorption and effectiveness of the medication. Taking it with food can interfere with absorption. Timing is also crucial; it is usually recommended to take levothyroxine in the morning to prevent potential interactions with food and other medications throughout the day. Taking the medication in the evening may lead to sleep disturbances. Lastly, waiting to take the medication only when symptoms occur is not appropriate as levothyroxine is typically taken regularly to maintain thyroid hormone levels within the body.
