What action should the nurse take to prevent the development of deep vein thrombosis (DVT) in a client who is postoperative day 2 following hip replacement surgery?

Correct Answer: B

Rationale: The correct action to prevent DVT in a postoperative client is to apply sequential compression devices (SCDs) to promote venous return. This helps prevent stasis of blood in the lower extremities, reducing the risk of clot formation. Encouraging bed rest (Choice A) may lead to decreased mobility and increase the risk of DVT. Massaging the client's legs (Choice C) is contraindicated in the presence of DVT as it can dislodge a clot. Encouraging ankle and foot exercises (Choice D) may be beneficial for circulation, but SCDs are more effective at preventing DVT in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Weighing daily and reporting significant weight loss is crucial when taking furosemide to monitor for potential fluid and electrolyte imbalances. Choice A is incorrect because furosemide is typically taken on an empty stomach for optimal absorption. Choice C is incorrect as furosemide can lead to potassium loss, so potassium-rich foods should be consumed. Choice D is incorrect because furosemide is usually taken earlier in the day to prevent nocturia, not at bedtime.

Correct Answer: C

Rationale: The correct answer is to use sterile technique when changing the dressing. This practice is essential for preventing infections that can compromise the patency of the PICC line. While flushing the catheter with heparin solution helps prevent clot formation, it does not directly maintain patency. Changing the dressing daily is important for hygiene but does not have a direct impact on catheter patency. Keeping the insertion site dry is crucial to prevent infections but does not specifically address patency maintenance.

Correct Answer: B

Rationale: Increased urine output is the correct assessment finding that indicates the client is responding to treatment for dehydration. When a client is dehydrated, their urine output tends to decrease as the body tries to conserve fluids. Therefore, an increase in urine output suggests that the client's hydration status is improving. Dry mucous membranes (Choice A) are a sign of dehydration and would not indicate a positive response to treatment. Decreased heart rate (Choice C) and elevated blood pressure (Choice D) are not specific indicators of hydration status in a client with dehydration.

Correct Answer: B

Rationale: The ventrogluteal site is the most appropriate and safest site for administering an intramuscular injection to an adult client. It is preferred due to its thick muscle mass and fewer major blood vessels and nerves in the area, reducing the risk of injury or complications. The deltoid muscle is commonly used for vaccines and small-volume injections but may not be suitable for larger volumes. The dorsogluteal site has fallen out of favor due to the risk of injury to the sciatic nerve and other underlying structures. The rectus femoris site is not typically used for intramuscular injections in adults.
