Correct Answer: C

Rationale: Evaluating client abilities to perform skills with return demonstrations is a good way for a nurse to prepare the environment for teaching. By observing the clients' abilities to perform the necessary skills, the nurse can tailor the teaching to meet the specific needs of each individual. Return demonstrations allow for immediate feedback and correction if needed, ensuring that the clients understand and can perform the skills accurately. This interactive approach to teaching promotes active learning and enhances retention of information.

Correct Answer: C

Rationale: When the nurse asks the patient to move an extremity away from the body midline, they are assessing the movement of abduction. Abduction refers to the movement of a body part away from the midline of the body. In this case, moving the extremity away from the body midline represents abduction, as the limb is being moved outward or away from the center of the body. Flexion and extension involve bending and straightening movements, respectively, along a joint axis, while adduction involves moving a body part towards the midline of the body.

Correct Answer: C

Rationale: Disseminated intravascular coagulation (DIC) is a condition characterized by widespread activation of clotting factors throughout the body, leading to both excessive clot formation and consumption of clotting factors. As a result, one of the common features of DIC is a decreased level of fibrinogen, which is an essential protein for blood clot formation. In DIC, fibrinogen is consumed in the formation of multiple small blood clots throughout the circulation, causing a decrease in its levels. This decrease in fibrinogen can contribute to the increased risk of bleeding that is seen in DIC. Therefore, a decreased fibrinogen level is a characteristic laboratory finding in DIC.

Correct Answer: D

Rationale: When performing medication teaching for the client's family about fibrinolytic therapy with alteplase (rt-PA), the nurse should include information that this medication is administered to break up existing clots and increase cerebral blood flow. rt-PA works by converting plasminogen to plasmin, which helps dissolve clots and restore blood flow to the brain. It is used specifically for ischemic strokes, not hemorrhagic strokes, and is most effective when administered within 3 hours (up to 4.5 hours in some cases) of the stroke symptoms starting. It is associated with potential serious complications, including an increased risk of bleeding, which the nurse should also educate the family about.
