Nursing Elites

1. What is the primary cause of diabetic ketoacidosis (DKA)?

• A. Insulin deficiency
• B. Overhydration
• C. Excess carbohydrate intake
• D. Excess insulin

Correct answer: A

Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.

2. While caring for a client with an AV fistula in the left forearm, the nurse observed a palpable buzzing sensation over the fistula. What action should the nurse take?

• A. Loosen the dressing of the fistula
• B. Report the presence of a bounding pulse
• C. Document that the fistula is intact
• D. Apply gentle pressure over the site

Correct answer: C

Rationale: The correct answer is C: Document that the fistula is intact. The palpable buzzing sensation (known as a thrill) over the AV fistula indicates proper functioning. It is essential for the nurse to document this finding to ensure ongoing monitoring of the fistula's status. Choices A, B, and D are incorrect. Choice A is incorrect because there is no indication to loosen the dressing. Choice B is incorrect as a bounding pulse is not associated with the palpable buzzing sensation of a thrill. Choice D is incorrect as applying pressure over the site is not necessary for this situation.

3. The PN is assisting the recreational director of a long-term care facility to plan outdoor activities for wheelchair-bound older residents who are mentally alert. Which activity meets the physical and social needs of these residents?

• A. An open-air concert
• B. A tea party in the courtyard
• C. A team ring-toss competition
• D. A picnic in the park

Correct answer: B

Rationale: A tea party in the courtyard is the most suitable activity as it allows for social interaction in a comfortable and accessible environment. Wheelchair-bound residents can easily participate, fostering both physical and social engagement. An open-air concert may pose challenges regarding accessibility and comfort for wheelchair-bound individuals. A team ring-toss competition involves physical activity that may not be inclusive for all residents, especially those in wheelchairs. A picnic in the park may also present challenges related to accessibility and comfort for wheelchair-bound individuals.

4. A male client who has been diagnosed with schizophrenia is withdrawn, isolates himself in the day room, and answers questions with one or two-word responses. This morning, the practical nurse observes that he is diaphoretic and is pacing in the hall. Which intervention is most important for the PN to implement?

• A. Persuade the client to lie down
• B. Provide a drink high in electrolytes
• C. Observe the client during the shift
• D. Measure appropriate vital signs

Correct answer: D

Rationale: Measuring vital signs is crucial in this situation as it helps to determine if the client is experiencing a physical health issue or if the symptoms are related to a mental health crisis, such as anxiety or agitation. The presence of diaphoresis and pacing may indicate physiological changes requiring immediate attention. Providing a drink high in electrolytes or persuading the client to lie down may not address the underlying cause of the symptoms. Simply observing the client during the shift without taking necessary actions to assess his physiological status may delay appropriate intervention.

5. When administering an analgesic to a client with low back pain, which intervention should the practical nurse implement to promote the effectiveness of the medication?

• A. Massage the lower back and position the client in proper alignment
• B. Encourage the client to ambulate frequently and take deep breaths
• C. Assist the client in performing passive and active range of motion exercises
• D. Give medication with a full glass of water and offer high-fiber foods

Correct answer: A

Rationale: Massaging the lower back and positioning the client in proper alignment can help relieve muscle tension and enhance the effectiveness of analgesics by providing additional comfort and promoting better pain management. This intervention directly addresses the site of pain and can improve the medication's efficacy. Choices B, C, and D are incorrect because while they may have benefits in other situations, they are not directly related to promoting the effectiveness of analgesics in clients with low back pain. Encouraging ambulation and deep breathing, assisting with range of motion exercises, and offering water and high-fiber foods are important for overall patient care but are not specific to enhancing analgesic effectiveness in this context.
