Nursing Elites

1. A client is receiving enoxaparin for the prevention of DVT. Which of the following is an appropriate action by the nurse?

• A. Expel any air bubbles from the prefilled syringe
• B. Massage the injection site to aid in absorption of the medication
• C. Inject the medication into the lateral abdominal wall
• D. Administer an NSAID for injection site discomfort

Correct answer: C

Rationale: The correct answer is to inject enoxaparin into the lateral abdominal wall for subcutaneous absorption. This site is commonly used for administering this type of medication. Expelling air bubbles from the syringe is not necessary and may result in a reduced dose being administered. Massaging the injection site is not recommended as it can lead to bruising or irritation. Administering an NSAID for injection site discomfort is not indicated as discomfort at the injection site is usually minimal and self-limiting.

2. A nurse in the telemetry unit is receiving the laboratory findings for an adult male client who is being treated for a myocardial infarction. Which of the following is an expected finding for the client?

• A. Troponin I (TnI) 8 ng/mL
• B. Brain natriuretic peptide (BNP) 10 ng/L
• C. Alanine aminotransferase (ALT) 45 units/L
• D. High-density lipoprotein (HDL) 75 mg/dL

Correct answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

3. A client at risk for coronary artery disease seeks advice from a nurse. What should the nurse recommend to reduce the risk?

• A. Increase your intake of saturated fats.
• B. Exercise for 150 minutes per week.
• C. Take iron supplements daily.
• D. Limit fruits and vegetables in your diet.

Correct answer: B

Rationale: The correct recommendation to reduce the risk of coronary artery disease is to exercise for at least 150 minutes per week. Regular exercise is crucial in maintaining cardiovascular health and reducing the chances of developing heart disease. Increasing intake of saturated fats (Choice A) is counterproductive as it can raise cholesterol levels and contribute to arterial plaque formation. Taking iron supplements daily (Choice C) is not directly related to reducing the risk of coronary artery disease. Limiting fruits and vegetables in the diet (Choice D) is also not advisable, as they are essential components of a heart-healthy diet due to their high fiber and nutrient content.

4. A healthcare professional is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 mL. How many mL would the healthcare professional administer per dose?

• A. 0.4 mL
• B. 0.3 mL
• C. 0.5 mL
• D. 0.6 mL

Correct answer: A

Rationale: To calculate the mL to be administered, convert 250 mg to grams (0.25 g). Then, set up a proportion: (0.25 g / 3 g) x 5 mL = 0.4167 mL, which rounds to 0.4 mL. Therefore, the healthcare professional would administer 0.4 mL per dose. Choice B (0.3 mL) is incorrect because it does not reflect the accurate calculation. Choice C (0.5 mL) is incorrect as it does not consider the correct conversion and calculation. Choice D (0.6 mL) is incorrect as it provides a value higher than the accurate calculation.

5. A nurse is caring for a group of clients in a long-term care facility. Which of the following situations should the nurse recognize as a safety hazard?

• A. A client’s wrist restraints tied to the bed rails
• B. A client’s bedside table placed across the foot of the bed
• C. A meal tray left at the bedside from breakfast
• D. A call light extension cord pinned to the bedspread

Correct answer: A

Rationale: The correct answer is A. Tying wrist restraints to the bed rails is a safety hazard because if the bed rails are lowered, the restraints can tighten and cause injury or asphyxiation. Choice B, placing a bedside table across the foot of the bed, may not be ideal for convenience but does not pose a direct safety hazard. Choice C, leaving a meal tray at the bedside from breakfast, is more of an infection control issue than an immediate safety hazard. Choice D, having a call light extension cord pinned to the bedspread, is also not a direct safety hazard unless it poses a risk of entanglement or tripping, which is not indicated in the scenario.
