Nursing Elites

1. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

2. A client with Cushing's syndrome presents with excessive bruising and elevated blood glucose. What action should the nurse take first?

• A. Check the client's blood glucose level.
• B. Administer insulin per sliding scale protocol.
• C. Administer intravenous fluids.
• D. Check the client's skin for signs of bruising.

Correct answer: A

Rationale: Excessive bruising and elevated blood glucose are common symptoms of Cushing's syndrome. The nurse should first check the client's blood glucose level to assess and address the hyperglycemia promptly. Administering insulin or IV fluids would be premature without knowing the current blood glucose level. Checking the skin for bruising, although important for overall assessment, does not address the immediate concern of elevated blood glucose.

3. The nurse is assessing a client 2 hours postoperatively following an appendectomy. The nurse should intervene for which abnormal finding?

• A. Heart rate of 88 beats per minute
• B. Blood pressure of 100/60
• C. Oxygen saturation of 94%
• D. Respiratory rate of 16

Correct answer: C

Rationale: The correct answer is C. Oxygen saturation levels below 95% indicate hypoxia and require immediate intervention. A heart rate of 88 beats per minute, a blood pressure of 100/60, and a respiratory rate of 16 are within normal ranges and do not require immediate intervention. Oxygen saturation is a critical parameter reflecting the client's oxygenation status.

4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

5. A client with hypothyroidism is prescribed levothyroxine. What should the nurse include in the teaching plan about this medication?

• A. Take the medication with a full meal
• B. Take the medication on an empty stomach
• C. Take the medication at bedtime
• D. Take the medication as needed for symptoms

Correct answer: B

Rationale: The correct answer is B: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to enhance absorption and effectiveness. The medication is typically taken in the morning before breakfast. Choice A is incorrect because taking levothyroxine with a full meal can decrease its absorption. Choice C is incorrect because bedtime dosing may lead to insomnia. Choice D is incorrect because levothyroxine is a daily medication for hypothyroidism, not to be taken as needed for symptoms.
