Nursing Elites

1. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.

2. A client with peripheral arterial disease (PAD) has cool and pale feet with diminished pulses. Which of the following interventions should the nurse implement?

• A. Keep the legs elevated above the level of the heart.
• B. Encourage the client to exercise daily.
• C. Apply warm compresses to the affected area.
• D. Apply ice packs to the affected area.

Correct answer: C

Rationale: In peripheral arterial disease (PAD), there is decreased blood flow to the extremities. Applying warm compresses helps dilate blood vessels, improve circulation, and relieve symptoms. Elevating the legs above the heart level may further compromise blood flow. Encouraging daily exercise is important in PAD management but may not be appropriate when the client has cool, pale feet with diminished pulses. Applying ice packs can worsen vasoconstriction and further reduce blood flow, exacerbating symptoms in PAD.

3. Which of the following indicates a potential complication of diabetes mellitus?

• A. Inflamed and painful joints.
• B. Blood pressure of 160/100 mm Hg.
• C. Stooped posture.
• D. Hemoglobin of 9 g/dL (90 g/L).

Correct answer: B

Rationale: A blood pressure of 160/100 mm Hg indicates hypertension, which is a common complication of diabetes mellitus due to atherosclerotic changes. Hypertension is a significant risk factor for cardiovascular diseases, which are prevalent in individuals with diabetes. Inflamed and painful joints (Choice A) are not directly related to diabetes complications but may be seen in conditions like arthritis. Stooped posture (Choice C) is more indicative of musculoskeletal issues like osteoporosis, not necessarily a typical complication of diabetes. Hemoglobin level of 9 g/dL (90 g/L) (Choice D) could signify anemia, which can occur in diabetes but is not a primary complication often associated with the disease.

4. When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?

• A. Aching pain in the left calf.
• B. Burning pain in the left calf.
• C. Numbness and tingling in the left leg.
• D. Coldness of the left foot and ankle.

Correct answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

5. The client is being educated by the healthcare provider about risk factors associated with atherosclerosis and methods to reduce the risk. Which of the following is a risk factor that the client cannot modify?

• A. Diabetes
• B. Age
• C. Exercise level
• D. Dietary preferences

Correct answer: B

Rationale: Age is a nonmodifiable risk factor for atherosclerosis because it is a natural part of the aging process. While lifestyle factors such as diabetes, exercise level, and dietary preferences can be modified to reduce the risk of atherosclerosis, age cannot be altered. Therefore, age is the correct answer. Diabetes, exercise level, and dietary preferences can all be improved or managed through interventions and lifestyle changes to mitigate the risk of atherosclerosis.
