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. The unit clerk reports to the charge nurse that a healthcare provider has written several prescriptions that are illegible and it appears the healthcare provider used several unapproved abbreviations in the prescriptions. What actions should the charge nurse take?
- A. Call the healthcare provider who wrote the prescription
- B. Attempt to clarify the prescriptions with the pharmacist
- C. Administer the medications as prescribed
- D. Ask another healthcare provider for clarification
Correct answer: A
Rationale: The correct action for the charge nurse to take is to call the healthcare provider who wrote the illegible prescriptions. It is crucial to clarify illegible prescriptions directly with the provider to ensure patient safety and prevent medication errors. Option B, attempting to clarify with the pharmacist, may lead to misinterpretation and is not the recommended first step. Administering the medications as prescribed without clarity can jeopardize patient safety, making option C incorrect. Asking another healthcare provider for clarification (option D) may not be effective as the responsibility lies with the provider who wrote the prescription.
3. 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.
4. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
5. Following discharge teaching, a male client with a duodenal ulcer tells the nurse he will drink plenty of dairy products to help coat and protect his ulcer. What is the best follow-up action by the nurse?
- A. Remind the client that it is also important to switch to decaffeinated coffee and tea.
- B. Suggest that the client also plans to eat frequent small meals to reduce discomfort.
- C. Review with the client the need to avoid foods that are rich in milk and cream.
- D. Reinforce this teaching by asking the client to list a dairy food that he might select.
Correct answer: C
Rationale: The correct answer is C because diets rich in milk and cream stimulate gastric acid secretion, which can exacerbate a duodenal ulcer. Therefore, it is essential to avoid foods that are rich in milk and cream. Choice A is incorrect because switching to decaffeinated coffee and tea does not address the issue of avoiding milk and cream products. Choice B is incorrect because while eating frequent small meals can help with discomfort, it does not address the specific issue of avoiding milk and cream. Choice D is incorrect as it does not address the need to avoid milk and cream products.
