Correct Answer: B

Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.

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: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.

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: A

Rationale: Assigning an admission with atrial fibrillation and heart failure to a PN is not appropriate. This complex case requires more advanced skills and should not be managed by a PN without adequate support. The PN may not have the necessary training or expertise to handle such a critical situation effectively. Choice B is a suitable assignment for a PN nursing student as they can handle a client who had a major stroke 6 days ago. Choice C is also appropriate as a child with burns receiving packed cells and albumin IV running can be managed by the charge nurse. Choice D is within the scope of practice for a UAP since an elderly client post-myocardial infarction a week ago may require basic care and assistance.
