Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has Cushing's disease. The nurse should expect an increase in which of the following laboratory values?

• A. Serum glucose level
• B. Serum potassium level
• C. Serum calcium level
• D. Serum sodium level

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is increased cortisol production, leading to elevated blood glucose levels. This occurs due to the role of cortisol in promoting gluconeogenesis and insulin resistance. Choices B, C, and D are incorrect because Cushing's disease is not typically associated with alterations in serum potassium, calcium, or sodium levels.

2. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

3. A nurse is providing discharge teaching to a client who has a new prescription for nitroglycerin sublingual tablets. Which of the following statements should the nurse include?

• A. Take the medication with food to reduce stomach upset.
• B. Store the medication in a cool, dry place.
• C. Take one tablet every 5 minutes until the pain is relieved, up to three doses.
• D. This medication may cause drowsiness.

Correct answer: C

Rationale: The correct answer is to instruct the client to take one nitroglycerin sublingual tablet every 5 minutes until the pain is relieved, up to three doses. This dosing regimen is essential for managing angina attacks effectively. Choice A is incorrect because nitroglycerin sublingual tablets should be placed under the tongue for rapid absorption, not taken with food. Choice B is incorrect because nitroglycerin tablets should be stored in their original container at room temperature, away from moisture and heat. Choice D is incorrect because nitroglycerin typically does not cause drowsiness as a side effect.

4. A healthcare provider is preparing to administer an intramuscular injection to a client. Which of the following sites should the healthcare provider select?

• A. Deltoid
• B. Vastus lateralis
• C. Rectus femoris
• D. Dorsogluteal

Correct answer: B

Rationale: The vastus lateralis is the preferred site for intramuscular injections in adults due to its large muscle mass and low risk of complications. The deltoid, although a common site for vaccines, has a smaller muscle mass and may not be suitable for all types of medications. The rectus femoris is a muscle in the thigh that is more commonly used for intramuscular injections in infants. The dorsogluteal site is no longer recommended due to its proximity to major nerves and blood vessels.

5. How should fluid balance be assessed in a patient with heart failure?

• A. Monitor daily weight
• B. Monitor input and output
• C. Check for edema
• D. Monitor blood pressure

Correct answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.
