While visiting with a resident

Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct: 1. Checking the resident's mouth helps to identify if the bleeding is originating from the nose or throat. 2. It is important to determine the source of bleeding to provide appropriate care. 3. If the bleeding is from the nose, elevating the head of the bed can help reduce blood flow to the head. 4. Counting respirations is not necessary for addressing a nosebleed. Summary: A: Not the best initial action as it does not help identify the source of bleeding. C: Can be done after identifying the source of bleeding but not the initial step. D: Not relevant to addressing a nosebleed.

Correct Answer: B

Rationale: The correct answer is B: Apnea. "Apnea" means the temporary absence of breathing. "Dyspnea" (A) refers to difficult or labored breathing, "Eupnea" (C) means normal breathing, and "Orthopnea" (D) is difficulty breathing when lying down. Apnea specifically indicates the complete cessation of breathing, making it the correct term for the absence of breathing.

Correct Answer: A

Rationale: The correct answer is A because a diuretic works by increasing urine formation in the kidneys, leading to increased excretion of water and electrolytes. This helps reduce fluid volume in the body by promoting the removal of excess fluids. Choice B is incorrect because diuretics actually increase urine output, not decrease it. Choice C is incorrect because some diuretics may lead to potassium loss rather than increase potassium levels. Choice D is incorrect because diuretics work by reducing fluid volume through increased urine formation, not by directly reducing fluid volume.

Correct Answer: D

Rationale: The correct answer is D because creating a sign to hang near the bed to alert all staff is essential to ensure proper handling and collection of the 24-hour urine specimen. This step helps prevent any errors or miscommunication among staff members regarding the urine collection process. Explanation: A: Using a specimen kit is important but not the most crucial task when collecting a 24-hour urine specimen. B: Cleaning the perineal area is not directly related to the collection of a 24-hour urine specimen. C: Using strainers to filter all urine is not necessary for a 24-hour urine collection and may not be practical in this context. In summary, option D is the correct choice as it directly addresses the need for clear communication and coordination among staff members during the urine collection process.

Correct Answer: C

Rationale: The correct answer is C: A draining wound. Sterile dressings are necessary for draining wounds to prevent infection and promote proper healing. Draining wounds have an increased risk of contamination, making the use of sterile dressings essential. Choice A, a paper cut, typically does not require a sterile dressing as it is a minor wound. Choice B, an intact wound, does not require a sterile dressing unless there is a risk of infection. Choice D, a clean dry wound, also does not require a sterile dressing as long as it remains clean and dry. In summary, choice C is correct because draining wounds require sterile dressings to prevent infection, while the other choices do not necessarily require sterile dressings unless there are specific risk factors present.
