1. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?
- A. Decreased calcium
- B. Elevated potassium
- C. Increased sodium
- D. Low hemoglobin
Correct answer: A
Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
2. A nurse organizes a community action group to help resolve health problems in a low-income neighborhood with a large population of recent immigrants from Africa. What problem should the nurse address first?
- A. High rate of unemployment.
- B. Low immunization rate of children.
- C. Provision of substandard health care.
- D. Access to bilingual care providers.
Correct answer: B
Rationale: The correct answer is B: Low immunization rate of children. Addressing low immunization rates is crucial as it directly impacts the health of children and the community by preventing the spread of infectious diseases. Option A, high rate of unemployment, though important for overall well-being, is not the most immediate health concern. Option C, provision of substandard health care, is a significant issue but may not be as urgent as ensuring children are immunized. Option D, access to bilingual care providers, is important for effective communication but is not as critical as addressing low immunization rates in this scenario.
3. Which assessment finding would most likely indicate a complication of enteral tube feeding?
- A. Abdominal distension
- B. Weight gain
- C. Decreased bowel sounds
- D. Diarrhea
Correct answer: A
Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.
4. An occupational health nurse is caring for an employee who was exposed to an unknown dry chemical, resulting in a chemical burn. Which of the following interventions should the nurse include in the plan of care?
- A. Irrigate the affected area with running water.
- B. Wash the affected area with antibacterial soap.
- C. Brush the chemical off the skin and clothing.
- D. Leave the clothing in place until emergency personnel arrive.
Correct answer: C
Rationale: The correct intervention for an employee exposed to an unknown dry chemical is to brush off the chemical from the skin and clothing. This helps prevent further skin contact before irrigation can be done. Irrigating the affected area with running water is crucial after brushing off the chemical to minimize the exposure. Washing the affected area with antibacterial soap is not appropriate for chemical burns, as soap can react with certain chemicals and worsen the situation. Leaving the clothing in place until emergency personnel arrive may allow the chemical to continue to harm the skin and should be avoided.
5. A client with chronic obstructive pulmonary disease (COPD) is using a metered-dose inhaler (MDI). What technique should the nurse emphasize?
- A. The importance of using a spacer
- B. How to synchronize breaths with inhaler activation
- C. Regular cleaning of the inhaler
- D. All of the above
Correct answer: D
Rationale: In managing COPD with a metered-dose inhaler (MDI), the nurse should emphasize all of the techniques mentioned. Using a spacer can help improve drug delivery and reduce the risk of oral thrush. Synchronizing breaths with inhaler activation ensures proper medication delivery to the lungs. Regular cleaning of the inhaler prevents blockages and ensures optimal functioning. Therefore, all these techniques are important for effective COPD management, making 'All of the above' the correct answer. Choices A, B, and C are all crucial components of proper MDI technique in COPD, so they are not individually sufficient without the others.
