Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A nurse in a provider's office is collecting information from an older adult who reports that he has been taking acetaminophen 500 mg/day for severe joint pain. The nurse should instruct the client that large doses of acetaminophen could cause which of the following adverse effects?

• A. Liver damage
• B. Renal failure
• C. Gastric bleeding
• D. Heart attack

Correct answer: A

Rationale: Correct Answer: Large doses of acetaminophen can cause liver damage, which is a known adverse effect of the medication. Acetaminophen is metabolized in the liver, and excessive amounts can overwhelm the liver's ability to process it, leading to hepatotoxicity. Renal failure (Choice B) is not typically associated with acetaminophen use. Gastric bleeding (Choice C) is more commonly linked to nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acetaminophen. Heart attack (Choice D) is not a recognized adverse effect of acetaminophen, which primarily affects the liver when taken in large amounts.

3. The nurse is providing wound care to a client with a stage 3 pressure ulcer that has a large amount of eschar. The wound care prescription states 'clean the wound and then apply collagenase.' Collagenase is a debriding agent. The prescription does not specify a cleaning method. Which technique should the nurse use to cleanse the pressure ulcer?

• A. Lightly coat the wound with povidone-iodine solution
• B. Irrigate the wound with sterile normal saline
• C. Flush the wound with sterile hydrogen peroxide
• D. Remove the eschar with a wet-to-dry dressing

Correct answer: B

Rationale: Irrigating the wound with sterile normal saline is the correct technique for cleansing a wound when the prescription does not specify a cleaning method. Sterile normal saline is a standard and safe solution that helps to remove debris and promote healing without damaging healthy tissue. Choice A, using povidone-iodine solution, can be cytotoxic and delay wound healing. Choice C, using hydrogen peroxide, can be cytotoxic, cause tissue damage, and delay wound healing. Choice D, using wet-to-dry dressing to remove eschar, is an outdated and non-selective method that can cause trauma to the wound bed and delay healing. Therefore, choice B is the best option for wound cleansing in this scenario.

4. A healthcare professional is collecting a urine specimen for a client to test via urine dipstick to determine the urine's specific gravity. The healthcare professional knows the result will indicate the amount of:

• A. Solutes in the urine
• B. Bacteria in the urine
• C. pH level of the urine
• D. Glucose in the urine

Correct answer: A

Rationale: Specific gravity measures the concentration of solutes in the urine, reflecting the kidney's ability to concentrate or dilute urine. Choice B, bacteria in the urine, is incorrect because specific gravity does not measure bacterial presence. Choice C, pH level of the urine, is incorrect as it refers to the acidity or alkalinity of the urine, not its specific gravity. Choice D, glucose in the urine, is incorrect as specific gravity does not directly measure glucose levels in urine.

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.
