Nursing Elites

1. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

2. A client with a history of seizures is prescribed phenytoin. Which instruction should the nurse include in the discharge teaching?

• A. Report any signs of a sore throat or fever immediately
• B. Take the medication with antacids to reduce stomach upset
• C. Discontinue the medication if you feel drowsy
• D. Increase the dosage if you experience an aura

Correct answer: A

Rationale: The correct answer is A: 'Report any signs of a sore throat or fever immediately.' Phenytoin can cause blood dyscrasias, which can manifest as a sore throat or fever. These symptoms could indicate a serious side effect that requires immediate medical attention. Choice B is incorrect because phenytoin should not be taken with antacids as they can decrease its absorption. Choice C is incorrect because discontinuing phenytoin abruptly can lead to rebound seizures; drowsiness is a common side effect that may improve with time. Choice D is incorrect because adjusting the dosage of phenytoin should only be done under healthcare provider supervision, not based on experiencing an aura.

3. While changing the dressing of a client with a leg ulcer, the nurse observes a red, tender, and swollen wound at the site of the lesion. Before reporting this finding to the healthcare provider, the nurse should note which of the client’s laboratory values?

• A. Neutrophil count.
• B. Hematocrit.
• C. Blood pH.
• D. Serum potassium and sodium.

Correct answer: A

Rationale: The correct answer is A: Neutrophil count. Neutrophil count helps assess for infection, which is indicated by the redness, tenderness, and swelling of the wound. Elevated neutrophil count is a common sign of bacterial infection. Hematocrit (choice B) measures the proportion of blood volume that is occupied by red blood cells and is not directly related to wound infection. Blood pH (choice C) and serum potassium and sodium (choice D) are important for assessing acid-base balance and electrolyte levels but are not the primary indicators of wound infection.

4. A client with urolithiasis is preparing for discharge after lithotripsy. Which intervention should the nurse include in the client's postoperative discharge instructions?

• A. Report when hematuria becomes pink-tinged
• B. Use incentive spirometer
• C. Restrict physical activities
• D. Monitor urinary stream for a decrease in output

Correct answer: D

Rationale: After lithotripsy, monitoring the urinary stream for a decrease in output is essential to identify any potential complications such as urinary retention or obstruction. Reporting pink-tinged hematuria is important, but monitoring the urinary stream for a decrease in output takes precedence as it directly assesses renal function and potential complications. Using an incentive spirometer is not directly related to post-lithotripsy care. Restricting physical activities may be necessary initially but is not the priority compared to monitoring urinary output.

5. A client who experienced partial-thickness burns with over 50% body surface area (BSA) 2 weeks ago suddenly becomes restless and agitated.

• A. Increase the room temperature.
• B. Assess the oxygen saturation.
• C. Continue to monitor vital signs.
• D. Notify the rapid response team.

Correct answer: D

Rationale: In a burn patient with sudden restlessness and agitation, it is crucial to consider hypoxia or other critical conditions. As such, notifying the rapid response team is the most appropriate action to ensure prompt assessment and intervention. Increasing room temperature (Choice A) is not the priority in this scenario. While monitoring vital signs (Choice C) is important, the sudden change in behavior warrants immediate action. Assessing oxygen saturation (Choice B) is a step in the right direction, but involving the rapid response team ensures a comprehensive evaluation and timely management of the patient's condition.
