1. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Arterial blood gases (ABGs)
- D. Echocardiogram
Correct answer: A
Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.
2. Which nursing intervention is most important when caring for a client with myasthenia gravis?
- A. Encourage the client to rest frequently.
- B. Administer medication 30 minutes before meals.
- C. Maintain a patent airway.
- D. Monitor for signs of respiratory infection.
Correct answer: C
Rationale: Maintaining a patent airway is crucial for clients with myasthenia gravis because muscle weakness can affect the muscles responsible for breathing, potentially leading to respiratory compromise. Encouraging rest, administering medication, and monitoring for respiratory infections are important aspects of care but do not take precedence over ensuring a patent airway for adequate oxygenation.
3. A 46-year-old male client who had a myocardial infarction 24 hours ago comes to the nurse's station fully dressed and wanting to go home. He tells the nurse that he is feeling much better at this time. Based on this behavior, which nursing problem should the nurse formulate?
- A. Ineffective coping related to denial.
- B. Risk for impaired cardiac function.
- C. Noncompliance related to lack of knowledge.
- D. Anxiety related to hospitalization.
Correct answer: A
Rationale: The correct answer is A: Ineffective coping related to denial. The client's desire to leave the hospital shortly after a myocardial infarction despite the severity of the condition indicates denial and ineffective coping. This behavior could lead to complications as the client may not adequately address his health needs. Choice B, Risk for impaired cardiac function, is not the most appropriate nursing problem in this scenario as the client's behavior is more indicative of psychological coping issues rather than a direct physiological risk at this moment. Choice C, Noncompliance related to lack of knowledge, does not align with the client's behavior of wanting to leave the hospital. Choice D, Anxiety related to hospitalization, may not be the best option as the client's behavior is more suggestive of denial rather than anxiety about being hospitalized.
4. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which intervention should the nurse implement first?
- A. Obtain a blood glucose level.
- B. Administer an anticoagulant as prescribed.
- C. Perform a neurological assessment.
- D. Administer aspirin as prescribed.
Correct answer: C
Rationale: Performing a neurological assessment is the priority in this situation as it helps in evaluating the cause of the new onset of confusion in a client with atrial fibrillation. This assessment will provide crucial information about the client's neurological status, which can guide further interventions. Obtaining a blood glucose level (Choice A) is important but should not be the first step when dealing with a new onset of confusion. Administering an anticoagulant (Choice B) or aspirin (Choice D) may be necessary depending on the underlying cause, but assessing the neurological status comes first to determine the appropriate course of action.
5. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?
- A. Serum sodium of 135 mEq/L
- B. Serum potassium of 4.0 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum glucose of 300 mg/dL
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.
