Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. A nurse is planning care for a client who is newly diagnosed with diabetes mellitus. Which instruction should the nurse include in this client’s teaching plan?

• A. Avoid all forms of sugar
• B. Check blood glucose levels once a week
• C. Rotate insulin injection sites
• D. Monitor urine ketone levels

Correct answer: C

Rationale: Rotating insulin injection sites prevents lipodystrophy and ensures proper insulin absorption.

3. The nurse is evaluating the health status of an older client. Which finding is most important for the nurse to report to the healthcare provider?

• A. Client reports decreased urine output
• B. Client reports loss of appetite
• C. Client reports pain in the lower back
• D. Client reports a persistent cough

Correct answer: C

Rationale: Pain in the lower back is a significant finding in an older client as it can indicate underlying issues such as kidney problems, spinal issues, or even aortic aneurysm. These conditions can be serious and require prompt medical attention. Decreased urine output (choice A) could indicate dehydration or kidney issues but is not as urgent as lower back pain. Loss of appetite (choice B) may be concerning but is not as critical as the potential life-threatening conditions associated with lower back pain. A persistent cough (choice D) is important to assess but is generally not as urgent as the potential serious implications of lower back pain in an older client.

4. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?

• A. Consuming a high-fat diet
• B. Using tanning beds
• C. Smoking cigarettes
• D. Drinking alcohol

Correct answer: B

Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.

5. Assessment findings of a 3-hour-old newborn include: axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate at 42 breaths/min. Based on these findings, what action should the nurse implement?

• A. Place a pulse oximeter on the heel
• B. Swaddle the infant in a warm blanket
• C. Record the findings on the flow sheet
• D. Check the vital signs in 15 minutes

Correct answer: C

Rationale: The correct answer is to record the findings on the flow sheet. These assessment findings are within normal limits for a 3-hour-old newborn. The axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate of 42 breaths/min are all expected in a newborn. No immediate intervention is needed, so the nurse should document these normal findings for future reference. Placing a pulse oximeter on the heel or swaddling the infant in a warm blanket is not indicated as the vital signs are within normal limits. Checking the vital signs in 15 minutes is unnecessary since the current findings are normal.
