Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A nurse is admitted to a psychiatric unit and fails to follow her medication regimen. What does this behavior indicate?

• A. Early cognitive impairment
• B. Lack of motivation
• C. Lack of health literacy
• D. Worsening health state

Correct answer: C

Rationale: The correct answer is C, 'Lack of health literacy.' The nurse's inability to follow the medication regimen suggests she may lack health literacy, meaning she may not fully understand how to manage her own health care. Choice A, 'Early cognitive impairment,' is not supported by the information provided in the question as there is no mention of cognitive decline. Choice B, 'Lack of motivation,' is less likely as the behavior is more indicative of a knowledge deficit rather than a lack of drive. Choice D, 'Worsening health state,' is also less likely as the behavior described does not directly imply a worsening health condition but rather a misunderstanding or lack of knowledge on managing health.

3. A nurse is caring for a client who has a new prescription for an antidepressant. The client reports experiencing dry mouth. Which of the following instructions should the nurse give the client?

• A. Decrease fluid intake.
• B. Chew sugarless gum.
• C. Avoid using mouthwash.
• D. Increase intake of dairy products.

Correct answer: B

Rationale: The correct answer is to instruct the client to chew sugarless gum. Chewing sugarless gum can help alleviate dry mouth by stimulating saliva production, which is a common side effect of many antidepressants. Decreasing fluid intake (choice A) is not recommended as it can worsen dry mouth. Avoiding mouthwash (choice C) is not as effective as chewing gum in stimulating saliva. Increasing intake of dairy products (choice D) is not directly related to managing dry mouth caused by antidepressants.

4. A nurse is caring for a client receiving corticosteroids. Which of the following should the nurse monitor?

• A. Blood glucose levels
• B. Blood pressure
• C. Serum potassium levels
• D. Both A and B

Correct answer: D

Rationale: When a client is receiving corticosteroids, the nurse should monitor both blood glucose levels and blood pressure. Corticosteroids can elevate blood glucose levels, leading to hyperglycemia, and may cause hypertension. Monitoring these parameters is essential to detect and address any potential adverse effects promptly. While monitoring serum potassium levels is important in some situations, it is not a primary concern when caring for a client receiving corticosteroids. Therefore, choices A and B are the most appropriate options for monitoring in this scenario, making option D the correct answer.

5. A charge nurse is discussing the use of applying ice to a client’s injured knee with a newly licensed nurse. Which of the following is a benefit of this treatment?

• A. Systemic analgesic effect
• B. Increase in metabolism
• C. Decreased capillary permeability
• D. Vasodilation

Correct answer: C

Rationale: The correct answer is C: Decreased capillary permeability. Ice application helps decrease capillary permeability, which in turn reduces swelling and inflammation at the injury site. This vasoconstriction effect helps to limit the extent of the injury. Choices A, B, and D are incorrect. Applying ice locally does not produce a systemic analgesic effect but rather a localized numbing effect. It does not increase metabolism but rather slows down metabolic processes in the affected area. Additionally, ice application causes vasoconstriction, not vasodilation.
