Nursing Elites

1. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?

• A. 12.5
• B. 5
• C. 10
• D. 20

Correct answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

2. A 10-month-old girl is admitted with a diagnosis of possible cystic fibrosis. What question should the nurse ask the parent to assist in the diagnosis of cystic fibrosis (CF)?

• A. When you kiss her, does she taste salty?
• B. Do you notice if her urine has a musty odor?
• C. Has she been drinking cow's milk in her daily diet?
• D. How often does she have a normal bowel movement?

Correct answer: A

Rationale: The correct answer is A. Salty skin is a common sign of cystic fibrosis due to high levels of sodium in sweat. Asking about the taste of the child's skin provides valuable information related to the diagnosis of CF. Choices B, C, and D are not helpful in diagnosing cystic fibrosis. A musty odor in urine is not a typical symptom of CF. Drinking cow's milk or bowel movement frequency are not specific to CF diagnosis.

3. A male client, admitted to the mental health unit for a somatoform disorder, becomes angry because he cannot have his pain medication. He demands that the nurse call the healthcare provider and threatens to leave the hospital. What action should the nurse take?

• A. Place the client in seclusion per unit guidelines
• B. Administer a PRN prescription for lorazepam (Ativan)
• C. Call security to help ensure staff and client safety
• D. Ask what other methods he uses to deal with pain

Correct answer: C

Rationale: In this scenario, the nurse should prioritize ensuring safety. When a client becomes aggressive and threatens to leave, calling security is crucial to help maintain a safe environment for both staff and the client. Placing the client in seclusion (choice A) is not the appropriate initial action as it may escalate the situation further. Administering lorazepam (choice B) should not be the first response to behavioral issues. Asking about other pain management methods (choice D) is not the immediate priority when safety is at risk.

4. A client presents to the healthcare provider with fatigue, poor appetite, general malaise, and vague joint pain that improves mid-morning. The client has been using over-the-counter ibuprofen for several months. The healthcare provider makes an initial diagnosis of rheumatoid arthritis (RA). Which laboratory test should the nurse report to the healthcare provider?

• A. Sedimentation rate
• B. White blood cell count
• C. Anti–CCP antibodies
• D. Activated Clotting Time

Correct answer: A

Rationale: The correct answer is A: Sedimentation rate. Sedimentation rate, Anti–CCP antibodies, and C-reactive protein are commonly used laboratory tests to indicate inflammation and help diagnose rheumatoid arthritis. An elevated sedimentation rate is a nonspecific indicator of inflammation in the body, which is often seen in RA. White blood cell count is not specific for RA and is not typically significant in the diagnosis. Anti–CCP antibodies are specific to RA and are useful in confirming the diagnosis. Activated Clotting Time is not relevant to the diagnosis of rheumatoid arthritis as it is not specific to this condition.

5. While changing a client’s chest tube dressing, the nurse notes a crackling sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube insertion site
• B. Assess the client for allergies to topical cleaning agents
• C. Measure the area of swelling and crackling
• D. Administer an oral antihistamine per PRN protocol

Correct answer: A

Rationale: A crackling sensation indicates subcutaneous emphysema, caused by air trapped under the skin. Applying a pressure dressing around the chest tube insertion site can help manage the issue by preventing further air leakage into the tissues. Choice B is incorrect because the crackling sensation is not related to allergies. Choice C is incorrect as measuring the area does not address the underlying cause. Choice D is incorrect as administering an oral antihistamine is not indicated for subcutaneous emphysema.
