Nursing Elites

1. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

2. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

3. While observing a student nurse administering a narcotic analgesic IM injection without aspirating, what should the nurse do?

• A. Ask the student, 'What did you forget to do?'
• B. Stop and explain why aspiration is needed.
• C. Quietly state, 'You forgot to aspirate.'
• D. Walk up and whisper in the student's ear, 'Stop. Aspirate. Then inject.'

Correct answer: D

Rationale: When the nurse observes a student nurse making a mistake during a procedure, such as not aspirating before administering a medication, the nurse should provide immediate, discreet feedback to correct the error. Walking up and whispering in the student's ear to stop, aspirate, and then inject is appropriate as it corrects the mistake while maintaining the student's dignity and confidence. Option A is not as effective as it indirectly addresses the issue. Option B is not the best approach as the student needs immediate correction. Option C is not ideal as loudly stating the mistake may embarrass the student and is not necessary for a discreet correction.

4. When assisting an 82-year-old client to ambulate, it is important for the LPN/LVN to realize that the center of gravity for an elderly person is in the

• A. Arms.
• B. Upper torso.
• C. Head.
• D. Feet.

Correct answer: B

Rationale: The correct answer is 'Upper torso.' In elderly individuals, the center of gravity tends to shift upwards towards the upper torso due to various factors such as changes in posture and muscle strength. Understanding this is crucial for safe ambulation as it helps in maintaining balance and stability. Choices A, 'Arms,' C, 'Head,' and D, 'Feet,' are incorrect. The center of gravity is not typically located in the arms, head, or feet. It is higher up in the body, specifically in the upper torso. Knowing the correct location of the center of gravity is essential for assisting elderly clients in ambulation effectively and preventing falls.

5. The nurse is caring for a client with a pressure ulcer on the sacrum. Which action should the LPN/LVN take to prevent further skin breakdown?

• A. Apply a hydrocolloid dressing to the ulcer.
• B. Reposition the client every 2 hours.
• C. Use a donut-shaped cushion when the client is sitting.
• D. Massage the area around the ulcer to promote circulation.

Correct answer: B

Rationale: Repositioning the client every 2 hours is the most appropriate action to prevent further skin breakdown in a client with a pressure ulcer on the sacrum. This practice helps relieve pressure on the affected area, promoting circulation and reducing the risk of tissue damage. Applying a hydrocolloid dressing (Choice A) may be beneficial for wound healing but is not the initial preventive measure. Using a donut-shaped cushion (Choice C) can actually increase pressure on the sacrum and worsen the condition. Massaging the area around the ulcer (Choice D) can further damage delicate skin and tissues, leading to more harm instead of prevention.
