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. An occupational health nurse is caring for an employee who was exposed to an unknown dry chemical, resulting in a chemical burn. Which of the following interventions should the nurse include in the plan of care?

• A. Irrigate the affected area with running water.
• B. Wash the affected area with antibacterial soap.
• C. Brush the chemical off the skin and clothing.
• D. Leave the clothing in place until emergency personnel arrive.

Correct answer: C

Rationale: The correct intervention for an employee exposed to an unknown dry chemical is to brush off the chemical from the skin and clothing. This helps prevent further skin contact before irrigation can be done. Irrigating the affected area with running water is crucial after brushing off the chemical to minimize the exposure. Washing the affected area with antibacterial soap is not appropriate for chemical burns, as soap can react with certain chemicals and worsen the situation. Leaving the clothing in place until emergency personnel arrive may allow the chemical to continue to harm the skin and should be avoided.

3. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing technique?

• A. The nurse washes with her hands held higher than her elbows.
• B. The nurse uses an alcohol-based hand rub for 30 seconds.
• C. The nurse scrubs hands and forearms for 2 minutes with soap and water.
• D. The nurse washes her hands with soap and water for only 15 seconds.

Correct answer: A

Rationale: Proper surgical hand-washing technique involves washing with the hands held higher than the elbows. This positioning is essential to ensure proper rinsing and to prevent the risk of contamination. Option B, using an alcohol-based hand rub for 30 seconds, is not specific to surgical hand-washing and is more commonly used for routine hand hygiene. Option C, scrubbing hands and forearms for 2 minutes with soap and water, is excessive and not typically required for routine hand-washing. Option D, washing hands with soap and water for only 15 seconds, is insufficient for thorough surgical hand-washing.

4. A nurse in an emergency department is assessing a client who reports diarrhea and decreased urination for 4 days. Which of the following actions should the nurse take to assess the client's skin turgor?

• A. Grasp a skin fold on the chest under the clavicle, release it, and note whether it springs back
• B. Pinch the skin on the back of the hand and observe for elasticity
• C. Assess the skin turgor on the abdomen by pinching the skin
• D. Check the skin turgor by pressing on the forearm and observing the rebound

Correct answer: A

Rationale: To assess skin turgor, the nurse should grasp a skin fold on the chest under the clavicle, release it, and note whether it springs back. This method is preferred for older adults and in cases of significant fluid imbalance. Option B is incorrect as assessing skin turgor on the back of the hand is not the standard assessment site for skin turgor. Option C is incorrect as the abdomen is not the typical area for assessing skin turgor; the chest under the clavicle is a more accurate site. Option D is incorrect as pressing on the forearm is not the appropriate site for evaluating skin turgor; the chest under the clavicle is the recommended location for this assessment.

5. A client has an indwelling urinary catheter. Which of the following actions should the nurse take to prevent infection?

• A. Ensure the catheter tubing is free of kinks.
• B. Clean the perineal area with antiseptic solution daily.
• C. Irrigate the catheter with normal saline every shift.
• D. Secure the catheter to the client's leg.

Correct answer: B

Rationale: Cleaning the perineal area with antiseptic solution daily is essential to prevent infection when caring for a client with an indwelling urinary catheter. This practice helps reduce the risk of introducing pathogens into the urinary tract. Ensuring the catheter tubing is free of kinks (Choice A) is important for maintaining proper urine flow but is not directly related to preventing infection. Irrigating the catheter with normal saline every shift (Choice C) is not a routine practice and can increase the risk of introducing pathogens. Securing the catheter to the client's leg (Choice D) is important for stability but does not directly prevent infection.
