Nursing Elites

1. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

2. A nurse is assessing four clients for fluid balance. Which of the following clients is exhibiting manifestations of dehydration?

• A. A client who has a urine specific gravity of 1.010.
• B. A client who has a weight gain of 2.2 kg (2 lb) in 24 hr.
• C. A client who has a hematocrit of 45%.
• D. A client who has a temperature of 39°C (102°F).

Correct answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

3. What is the name of a legal document that instructs health care providers and family members about what life-sustaining treatment an individual wants if they are unable to make decisions?

• A. Do Not Resuscitate
• B. Informed consent
• C. Living will
• D. Durable power of attorney for health care

Correct answer: C

Rationale: The correct answer is C, 'Living will.' A living will is a legal document that outlines an individual's preferences for life-sustaining medical treatment if they become unable to make decisions. Choice A, 'Do Not Resuscitate,' specifically refers to a directive that instructs healthcare providers not to perform CPR. Choice B, 'Informed consent,' pertains to a patient's right to be informed about and consent to medical treatment. Choice D, 'Durable power of attorney for health care,' involves appointing someone to make healthcare decisions on behalf of an individual when they are unable to do so.

4. A nurse is assessing a client with a history of heart failure. Which of the following findings should the nurse monitor?

• A. Increased energy
• B. Peripheral edema
• C. Elevated heart rate
• D. Improved lung sounds

Correct answer: B

Rationale: The correct answer is B: Peripheral edema. In heart failure, the heart's inability to pump effectively can lead to fluid backup, causing swelling in the extremities, known as peripheral edema. Monitoring for peripheral edema is crucial as it is a common sign of worsening heart failure. Choices A, C, and D are incorrect because increased energy, elevated heart rate, and improved lung sounds are not typical findings in heart failure. Increased energy is not usually associated with heart failure, an elevated heart rate may occur as a compensatory mechanism but is not a direct sign of heart failure, and improved lung sounds are not expected in heart failure which often presents with crackles or wheezes due to pulmonary congestion.

5. A nurse is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the nurse include in the teaching?

• A. Inhale the medication deeply for 3-5 seconds
• B. Exhale forcefully before inhaling
• C. Shake the MDI vigorously before use
• D. Hold the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth

Correct answer: A

Rationale: Corrected Rationale: Inhaling the medication deeply for 3-5 seconds and holding the breath for 10 seconds after inhalation ensures effective medication delivery to the lungs. Choice A is the correct instruction for the use of a metered-dose inhaler (MDI). Choice B, exhaling forcefully before inhaling, is incorrect as it can lead to decreased medication delivery. Choice C, shaking the MDI vigorously before use, is also incorrect as excessive shaking can cause the medication to clump. Choice D, holding the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth, is not recommended as it may lead to improper inhalation technique.
