Nursing Elites

1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

2. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

3. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?

• A. Administer an epinephrine injection
• B. Call for immediate medical help
• C. Monitor airway, breathing, and circulation
• D. All of the above

Correct answer: A

Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.

4. The healthcare provider is assessing a client who has just undergone a thoracentesis. Which finding should be reported immediately?

• A. Diminished breath sounds on the affected side.
• B. Pain at the procedure site.
• C. Blood-tinged sputum.
• D. Shortness of breath.

Correct answer: D

Rationale: Shortness of breath should be reported immediately as it may indicate a pneumothorax, a potential complication of thoracentesis. Diminished breath sounds on the affected side, pain at the procedure site, and blood-tinged sputum are common findings post-thoracentesis and do not necessarily indicate immediate complications like a pneumothorax.

5. What skin care measure should the nurse implement for a client who underwent external radiation treatment the previous day?

• A. Cleanse the radiated area with water and pat the skin dry
• B. Lightly massage the radiated skin with a lanolin-based lotion
• C. Rinse the site with normal saline and cover with a sterile towel
• D. Use a soft washcloth to gently remove the skin markings

Correct answer: A

Rationale: The correct measure for skin care after external radiation treatment is to cleanse the radiated area with water and pat the skin dry. This gentle cleansing without harsh chemicals or friction helps protect the integrity of radiated skin, preventing irritation or further damage. Choice B is incorrect because massaging radiated skin can cause further irritation, which should be avoided. Choice C is incorrect as rinsing with normal saline and covering with a sterile towel may not be necessary and could potentially introduce infection due to excessive moisture. Choice D is incorrect as using a soft washcloth to remove skin markings can be too abrasive for radiated skin, risking damage and irritation.
