Correct Answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.

Correct Answer: D

Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.

Correct Answer: C

Rationale: Shortness of breath is the most concerning symptom in a client with deep vein thrombosis (DVT) because it could indicate a pulmonary embolism, a life-threatening complication where a blood clot travels to the lungs. This condition requires immediate medical attention. While pain, redness, warmth, and swelling in the affected leg are common symptoms of DVT, shortness of breath suggests a more critical situation that necessitates urgent intervention.

Correct Answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

Correct Answer: D

Rationale: The correct answer is to stand close to the cabinet when lifting it. This action keeps the object close to the nurse's center of gravity, reducing the risk of back strain. Bending at the waist (Choice A) can increase the risk of back injury as it puts strain on the lower back. Keeping feet close together (Choice B) does not provide a stable base of support for lifting a heavy object. Using back muscles for lifting (Choice C) is incorrect as it can lead to back strain and injury. Therefore, standing close to the cabinet when lifting it is the safest and most effective approach to prevent self-injury.
