1. In planning care for a postoperative client with hypovolemic shock, which problem is most important to include in the plan of care?
- A. Risk for infection.
- B. Risk for falls.
- C. Impaired skin integrity.
- D. Activity intolerance.
Correct answer: B
Rationale: The correct answer is B: Risk for falls. In a postoperative client with hypovolemic shock, the most crucial problem to address is the risk for falls. Hypovolemic shock can result in dizziness and weakness, making the client prone to falling. Preventing falls is essential to avoid further injury or complications. Choices A, C, and D are not the top priority in this scenario. While infection, impaired skin integrity, and activity intolerance are important concerns, preventing falls takes precedence due to the immediate risk of injury associated with hypovolemic shock.
2. The healthcare provider prescribes Cytovene 375 mg every 12 hours to infuse over 90 minutes. The pharmacy delivers Cytovene 375 mg in a 150 mL IV bag. How many ml/hour should the nurse program the infusion pump?
- A. 50 ml/hour.
- B. 75 ml/hour.
- C. 100 ml/hour.
- D. 125 ml/hour.
Correct answer: C
Rationale: To infuse 150 mL over 90 minutes, the pump should be set to 100 ml/hour (150 mL / 1.5 hours). This rate ensures that the medication is delivered at the proper rate as prescribed. Choices A, B, and D are incorrect because they do not reflect the correct calculation based on the volume of the IV bag and the infusion duration provided in the question.
3. In the change of shift report, the nurse is told that a client has a stage 2 pressure ulcer. Which ulcer appearance is most likely to be observed?
- A. Shallow open ulcer with a red-pink wound bed.
- B. Intact skin with non-blanchable redness.
- C. Full-thickness tissue loss with visible fat.
- D. Full-thickness tissue loss with exposed bone, tendon, or muscle.
Correct answer: A
Rationale: The correct answer is A: 'Shallow open ulcer with a red-pink wound bed.' Stage 2 pressure ulcers involve partial-thickness skin loss and typically appear as shallow open ulcers with a red-pink wound bed. Choice B describes a stage 1 ulcer, where the skin is intact but shows non-blanchable redness. Choice C describes a stage 3 ulcer, with full-thickness tissue loss exposing fat. Choice D is characteristic of a stage 4 ulcer, where there is full-thickness tissue loss exposing bone, tendon, or muscle. Therefore, option A best fits the description of a stage 2 pressure ulcer.
4. The nurse is providing postoperative care for a client who had a thyroidectomy. Which assessment finding requires immediate intervention?
- A. Hoarseness and weak voice
- B. Calcium level of 8.0 mg/dL (2.0 mmol/L)
- C. Heart rate of 110 beats per minute
- D. Difficulty swallowing
Correct answer: D
Rationale: Difficulty swallowing can indicate swelling or hematoma formation, which may compromise the airway and requires immediate intervention. Hoarseness and a weak voice are expected post-thyroidectomy due to manipulation of the laryngeal nerves but do not require immediate intervention. A calcium level of 8.0 mg/dL is within the normal range (8.5-10.5 mg/dL) and may not require immediate intervention. A heart rate of 110 beats per minute may be elevated due to stress or pain postoperatively, but it does not indicate an immediate threat to the airway.
5. 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.
