Nursing Elites

1. An older client is admitted with fluid volume deficit and dehydration. Which assessment finding is the best indicator of hydration status?

• A. Urine specific gravity of 1.040.
• B. Systolic blood pressure decreases by 10 points when standing.
• C. The client denies feeling thirsty.
• D. Skin turgor exhibits tenting on the forearm.

Correct answer: A

Rationale: In the context of fluid volume deficit and dehydration, urine specific gravity of 1.040 is the best indicator of hydration status. High urine specific gravity indicates concentrated urine, suggesting dehydration. Choice B, systolic blood pressure decreasing when standing, is more indicative of orthostatic hypotension rather than hydration status. Choice C, denial of thirst, is a subjective finding and may not always reflect actual hydration status. Choice D, skin turgor exhibiting tenting on the forearm, is a sign of dehydration but may not be as accurate as urine specific gravity in assessing hydration status.

2. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?

• A. Three apricots
• B. Medium banana
• C. Naval orange
• D. Baked potato

Correct answer: D

Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.

3. 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.

4. A client with adrenal crisis has a temperature of 102°F, heart rate of 138 bpm, and blood pressure of 80/60 mmHg. Which action should the nurse implement first?

• A. Obtain an analgesic prescription.
• B. Infuse intravenous fluid bolus.
• C. Administer PRN oral antipyretic.
• D. Cover the client with a cooling blanket.

Correct answer: B

Rationale: In a client with adrenal crisis presenting with a high temperature, tachycardia, and hypotension, the priority action for the nurse to implement first is to infuse an intravenous fluid bolus. This intervention aims to address the hypotension by increasing the circulating volume and improving perfusion. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering an oral antipyretic (Choice C) may help reduce the fever but does not address the primary issue of hypotension. Covering the client with a cooling blanket (Choice D) may help with temperature control but does not address the hemodynamic instability caused by the adrenal crisis.

5. A client with hyperthyroidism is admitted to the postoperative unit after a subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Blood glucose 90 mg/dL
• B. Sodium 138 mEq/L
• C. Total calcium 5.0 mg/dL
• D. Potassium 4.2 mEq/L

Correct answer: C

Rationale: A total calcium level of 5.0 mg/dL is critically low and indicates possible hypocalcemia, a common complication after thyroid surgery. This condition can lead to tetany and requires immediate intervention. Blood glucose within normal range, sodium, and potassium levels are not indicative of an immediate postoperative complication like hypocalcemia in this case.
