A nurse is caring for a client who has an extracellular fluid volume deficit. Which of the following findings should the nurse expect?
Dependent edema
Distended neck veins
Postural hypotension
Bradycardia
The Correct Answer is C
Choice A reason:
Dependent edema is not typically associated with extracellular fluid volume deficit. Edema usually occurs due to fluid overload or conditions that cause fluid retention, such as heart failure or kidney disease. In the case of extracellular fluid volume deficit, the body is losing more fluid than it is taking in, which would not result in edema. Instead, symptoms like dry skin, dry mucous membranes, and decreased skin turgor are more common.
Choice B reason:
Distended neck veins are also not a common finding in extracellular fluid volume deficit. Distended neck veins are usually seen in conditions where there is fluid overload or increased pressure in the venous system, such as heart failure or superior vena cava syndrome. In extracellular fluid volume deficit, the body is experiencing a reduction in fluid volume, which would not cause distended neck veins.
Choice C reason:
Postural hypotension, also known as orthostatic hypotension, is a common finding in extracellular fluid volume deficit. This condition occurs when there is a significant drop in blood pressure upon standing, leading to dizziness or lightheadedness. It is caused by the reduced blood volume, which decreases the amount of blood returning to the heart and subsequently lowers blood pressure.
Choice D reason:
Bradycardia, or a slow heart rate, is not typically associated with extracellular fluid volume deficit. In fact, the opposite is more likely to occur. Tachycardia, or a fast heart rate, is a common compensatory mechanism in response to fluid volume deficit as the body attempts to maintain adequate blood flow and pressure. Therefore, bradycardia would not be an expected finding in this scenario.

Correct Answer is C
Explanation
Choice A Reason:
Rotating the swab over necrotic tissue is not recommended because necrotic tissue does not provide an accurate representation of the microorganisms present in the wound. Necrotic tissue is dead tissue, and culturing it can lead to misleading results, as it may not reflect the current state of infection or the microorganisms causing the infection.
Choice B Reason:
Obtaining the sample from the outer edge of the wound is also not ideal. The outer edge of the wound may be contaminated with skin flora or other external contaminants, which can lead to inaccurate culture results. The sample should be taken from clean, viable tissue within the wound bed to ensure accurate identification of the microorganisms present.
Choice C Reason:
Applying sterile gloves to remove the outer dressing is the correct action. This step is crucial to maintain aseptic technique and prevent contamination of the wound and the specimen. Sterile gloves help ensure that the nurse does not introduce any external microorganisms into the wound while handling the dressing.
Choice D Reason:
Crushing the transport medium after obtaining the specimen is a necessary step to activate the medium and preserve the specimen during transport to the laboratory. However, this step comes after the specimen has been collected and does not directly relate to the technique of obtaining the specimen.
Correct Answer is A
Explanation
Choice A Reason
Waiting 5 minutes between the administration of each medication is the most appropriate action. This allows each medication to be absorbed properly without being washed away by the subsequent drops. Adequate absorption ensures that each medication can exert its therapeutic effect effectively.
Choice B Reason
Asking the client to close their eyes tightly after instilling each medication is not recommended. This action can force the medication out of the eye, reducing its effectiveness. Instead, clients should be advised to close their eyes gently to allow the medication to spread evenly across the eye surface.
Choice C Reason
Holding the dropper 3 cm (1.2 in) away from the client’s eye is too far. The recommended distance is about 1 to 2 cm (0.4 to 0.8 in) to ensure that the drops are accurately placed in the conjunctival sac without touching the eye or eyelashes, which could cause contamination.
Choice D Reason
Massaging the client’s eyelids for 20 seconds after instillation is not a standard practice for administering ophthalmic drops. This action could potentially irritate the eye or cause discomfort. Instead, gentle pressure can be applied to the inner corner of the eye (nasolacrimal duct) for a few seconds to prevent the medication from draining into the tear duct.
