Correct Answer: A

Rationale: Using a designated stethoscope is the correct action when caring for a toddler diagnosed with RSV. This measure helps prevent the spread of infection to other clients by reducing the risk of contamination. Wearing an N95 respirator mask is not necessary for routine care of a toddler with RSV unless performing aerosol-generating procedures. Removing the disposable gown after leaving the toddler's room is important for infection control but not specific to RSV care. Placing the toddler in a room with negative air pressure is not a standard practice for managing RSV in toddlers.

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: D

Rationale: The correct answer is D: Drink hot water with lemon juice each morning. Drinking hot water with lemon juice can help stimulate bowel movements, making it a natural and safe recommendation for pregnant clients experiencing constipation. Choice A is incorrect because reducing vitamin and supplement intake may not directly address constipation. Choice B, eating 15 g of fiber per day, could be helpful but may not be as effective as the correct answer for immediate relief. Choice C, consuming 48 ounces of water daily, is essential for overall health but may not be as directly effective as the correct answer in alleviating constipation.

Correct Answer: C

Rationale: Instructing a patient about incentive spirometry falls under the implementation phase of the nursing process. During this phase, nursing interventions are put into action. Assessment (choice A) involves collecting data about the patient's condition, planning (choice B) involves setting goals and creating a care plan, and evaluation (choice D) involves assessing the outcomes of nursing interventions. Therefore, the correct answer is C, as it reflects the active teaching and intervention part of the process.

Correct Answer: D

Rationale: The correct answer is to elevate the affected leg while in bed. Elevating the leg helps reduce swelling and promotes venous return, aiding in the management of DVT. Positioning the affected leg below the heart can worsen the condition by increasing the risk of clot dislodgment. Massaging the affected extremity can also dislodge the clot and should be avoided. Cold compresses are not recommended as they can cause vasoconstriction, potentially worsening the condition.
