Nursing Elites

1. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

2. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?

• A. Anesthesia reaction
• B. Hyperglycemia
• C. Hypoglycemia
• D. Diabetic ketoacidosis

Correct answer: C

Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.

3. The nurse is taking the health history of a patient being treated for Emphysema and Chronic Bronchitis. After being told the patient has been smoking cigarettes for 30 years, the nurse expects to note which assessment finding?

• A. Increase in Forced Vital Capacity (FVC)
• B. A widened chest cavity
• C. Clubbed fingers
• D. An increased risk of cardiac failure

Correct answer: C

Rationale: 1. Increase in Forced Vital Capacity (FVC): Forced Vital Capacity is the volume of air exhaled from full inhalation to full exhalation. A patient with COPD would have a decrease in FVC. Therefore, this choice is incorrect. 2. A widened chest cavity: A patient with COPD often presents with a 'barrel chest,' which is seen as a widened chest cavity. Hence, a narrowed chest cavity is not an expected finding. 3. Clubbed fingers - CORRECT: Clubbed fingers are a sign of a long-term, or chronic, decrease in oxygen levels, which is commonly seen in patients with chronic respiratory conditions like Emphysema and Chronic Bronchitis. 4. An increased risk of cardiac failure: Although a patient with these conditions would indeed be at an increased risk for cardiac failure, this is a potential complication and not an assessment finding, making it an incorrect choice.

4. A client is in the post-anesthesia care unit (PACU) shivering despite being covered with several layers of blankets. What is the nurse's next action?

• A. Turn the client to the prone position
• B. Assist the client in breathing deeply
• C. Administer meperidine as ordered
• D. None of the above

Correct answer: C

Rationale: In the post-anesthesia care unit, clients may experience shivering or chills due to a drop in body temperature after surgery. Meperidine (Demerol) can be prescribed to alleviate shivering in cold clients. The prone position (lying face down) and deep breathing exercises are not interventions specifically indicated for addressing shivering due to low body temperature. Therefore, administering meperidine as ordered is the most appropriate action to manage the client's shivering in this scenario.

5. The nurse is reviewing the characteristics of culture. Which statement is correct regarding the development of one's culture?

• A. Learned through language acquisition and socialization.
• B. Genetically determined on the basis of racial background.
• C. A nonspecific phenomenon and is adaptive but unnecessary.
• D. Biologically determined on the basis of physical characteristics.

Correct answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.
