Question 1 of 9

What increases after an embolus has become trapped in the pulmonary microvasculature?

Correct Answer: C

Rationale: After an embolus becomes trapped in the pulmonary microvasculature, dead space increases. Dead space refers to the portion of the lung that is ventilated but not perfused, resulting in reduced gas exchange. When a pulmonary embolus blocks blood flow within a pulmonary vessel, it leads to a mismatch between ventilation and perfusion in the affected lung region. This mismatch results in increased dead space, as ventilation continues in areas that are not effectively perfused. As dead space increases, the overall efficiency of gas exchange in the lung is impaired, potentially leading to hypoxemia.

Question 2 of 9

A client diagnosed with cardiomyopathy reports having to rest between activities during the day. The client asks the nurse why this is occurring. Which reason should the nurse include in the response to the client?

Correct Answer: B

Rationale: The client with cardiomyopathy may experience decreased cardiac output, which is a common manifestation of this condition. Cardiomyopathy is a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body. Reduced cardiac output means that less blood is being pumped out by the heart with each beat, leading to symptoms such as fatigue, weakness, and the need to rest between activities. This is why the client is experiencing the need to rest between activities during the day.

Question 3 of 9

The nurse is evaluating teaching provided to a client with peripheral vascular disease (PVD). Which client observation indicates teaching has been effective?

Correct Answer: B

Rationale: Option B, washing the lower extremities with mild soap, drying the legs, and applying a light moisturizer, indicates effective teaching for a client with peripheral vascular disease (PVD). Proper hygiene, including gentle washing with mild soap, thorough drying to prevent moisture-related skin breakdown, and moisturizing to prevent dry skin and promote circulation, are key components of self-care for individuals with PVD. Option A is incorrect because sitting with a pillow behind the knees does not specifically address PVD self-care. Option C is incorrect because crossing the left leg over the right while sitting does not relate to appropriate PVD management. Option D is incorrect because smoking in any form is detrimental to vascular health and should be discouraged in PVD management.

Question 4 of 9

An older adult client receiving medication for hypertension had a recent fall at home. Which intervention should the nurse include in this client's plan of care?

Correct Answer: B

Rationale: Assessing postural blood pressures is important in determining if the client may be experiencing orthostatic hypotension, which could have contributed to the fall. Orthostatic hypotension is a sudden drop in blood pressure that can occur when a person stands up from a sitting or lying position. Older adults on antihypertensive medications are at increased risk for orthostatic hypotension. By monitoring postural blood pressures, the nurse can identify fluctuations in blood pressure that may put the client at risk for falls and implement appropriate interventions to prevent future falls. Monitoring serum sodium levels and creatinine levels are important for detecting electrolyte imbalances or kidney dysfunction but do not directly address the issue of orthostatic hypotension related to falls. Monitoring blood pressure every 2 hours may not provide valuable information on postural blood pressure changes that are associated with orthostatic hypotension.

Question 5 of 9

The nurse is caring for a child who has just been diagnosed with an atrial septal defect (ASD). Which manifestations would the nurse expect upon assessment? Select all that apply.

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Question 6 of 9

During an assessment, the nurse asks the patient to move an extremity away from the body midline. What movement is the nurse assessing?

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.

Question 7 of 9

A client diagnosed with a stroke is going to receive treatment with fibrinolytic therapy using the recombinant tissue plasminogen activator alteplase (rt-PA). Which information should the nurse include when performing medication teaching for the client's family?

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.

Question 8 of 9

A perimenopausal patient is experiencing frequency, urgency, nocturia, dysuria, and cloudy, rust- colored urine for the third time in the past 2 years. What should the nurse include when teaching this patient? Select all that apply.

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
