Correct Answer: B

Rationale: The correct answer is B: 'Take with a glass of orange juice.' Ferrous sulfate should be taken with orange juice (vitamin C) to enhance the absorption of iron. Taking it with milk (choice A) is not recommended as calcium can interfere with iron absorption. Taking it at bedtime (choice C) or with meals (choice D) may lead to decreased absorption due to interactions with other food or medications.

Correct Answer: B

Rationale: The correct answer is to inject enoxaparin in the lateral abdominal wall. This site is typically recommended for subcutaneous injections of this medication. Expelling air bubbles from prefilled syringes is not necessary and may result in medication loss. Massaging the injection site is contraindicated as it can cause bruising or hematoma formation. Administering NSAIDs for injection site discomfort is unnecessary and not a standard practice.

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 instruct the client to increase their intake of potassium-rich foods. Furosemide, a loop diuretic, can lead to potassium loss, which may cause hypokalemia. Increasing potassium intake can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide is usually taken in the morning to prevent sleep disturbances due to increased urination. Choice C is incorrect because a decrease in urine output could indicate a problem and should be reported immediately. Choice D is incorrect because furosemide is used to reduce swelling in the body, including the lower extremities, so expecting swelling is not appropriate.

Correct Answer: B

Rationale: The Partial Thromboplastin Time (PTT) is the correct laboratory value to monitor heparin therapy. PTT measures the time it takes for blood to clot and is specifically used to evaluate the effectiveness of anticoagulation therapy such as heparin. Monitoring the PTT helps ensure that the heparin dose is within the therapeutic range. Platelet count, Prothrombin time (PT), and Bleeding time are not specific laboratory values for monitoring the therapeutic effect of heparin therapy. Platelet count is more indicative of platelet function, PT is used to monitor warfarin therapy, and Bleeding time assesses platelet function rather than the effect of heparin therapy.
