A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?

Correct Answer: B

Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.

Correct Answer: C

Rationale: In the scenario described, the client has a living will that declines resuscitation. Therefore, if the client arrives at the emergency department with difficulty breathing, healthcare providers would consult the living will to understand the client's wishes. Providing comfort care, which may include oxygen therapy to alleviate symptoms, aligns with the client's preferences. Option A incorrectly suggests an intervention that goes against the client's wishes. Option B is incorrect because full resuscitation efforts are not in line with the client's choice to decline resuscitation. Option D is also incorrect as it does not consider the client's living will and the need to provide care according to the documented preferences of the client.

Correct Answer: A

Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.

Correct Answer: A

Rationale: When a debilitated patient resists oral hygiene, the nurse should prioritize safety. Inserting an oral airway helps keep the mouth open, ensuring adequate access for oral care procedures while preventing any accidental biting or closure of the airway. Placing the patient in a flat, supine position may not address the resistance issue and can lead to aspiration risk. Using undiluted hydrogen peroxide is not recommended due to its potential harmful effects on oral tissues. Proceeding quickly without communication can escalate the situation and compromise patient-centered care.

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates an understanding that soap and water should be used when hands are visibly dirty or when dealing with specific pathogens. Choice A is incorrect because it suggests the use of soap and water over alcohol-based hand rub without specifying the circumstances. Choice B is incorrect as it implies that using alcohol-based hand rub after using the restroom is always suitable. Choice D is incorrect because it states that hand rub is always enough, which is not true when hands are visibly soiled or when specific pathogens are present.

Correct Answer: B

Rationale: Donating autologous blood before surgery is an appropriate suggestion by the nurse. This process involves the patient donating their own blood before the surgery, which reduces the risk of infection from transfusions as the patient is receiving their own blood. Choice A is incorrect as avoiding the blood transfusion may not be feasible or safe in the context of expected blood loss during surgery. Choice C is not a common practice and may carry its own risks. Choice D is not directly related to reducing the risk of infection from a blood transfusion.

Correct Answer: C

Rationale: Shortness of breath in a client with a history of hypertension is a critical assessment finding as it may indicate heart failure, pulmonary edema, or other severe complications. The development of shortness of breath suggests that the client's condition may be rapidly deteriorating and requires immediate medical attention. Elevated blood pressure (150/90 mmHg) is concerning but not as acute as the potential complications associated with shortness of breath. An irregular heart rate and headache can also be symptoms of hypertension, but in this scenario, shortness of breath poses a higher risk of severe cardiovascular or respiratory issues.

Correct Answer: B

Rationale: The correct instruction to include in the teaching plan for a client who had a hemiarthroplasty of the left hip is to 'Place a pillow between your knees while lying in bed to prevent hip dislocation.' This technique helps maintain proper hip alignment and prevents dislocation during the postoperative recovery period. Choice A is incorrect because bending at the waist to reach items on the floor can strain the hip joint and is not recommended following hip surgery. Choice C is incorrect because using a walker alone without assistance can increase the risk of falls and injury, especially in the immediate postoperative period. Choice D is incorrect because pain medication should be taken as prescribed by the healthcare provider, not specifically timed after physical therapy sessions.

Correct Answer: B

Rationale: Cleaning the perineal area with antiseptic solution daily is essential to prevent infection when caring for a client with an indwelling urinary catheter. This practice helps reduce the risk of introducing pathogens into the urinary tract. Ensuring the catheter tubing is free of kinks (Choice A) is important for maintaining proper urine flow but is not directly related to preventing infection. Irrigating the catheter with normal saline every shift (Choice C) is not a routine practice and can increase the risk of introducing pathogens. Securing the catheter to the client's leg (Choice D) is important for stability but does not directly prevent infection.
