Correct Answer: C

Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.

Correct Answer: C

Rationale: The correct answer is C: Collaborative problem. The nurse needs to revise the collaborative problem part of the diagnostic statement because impaired physical mobility related to tibial fracture is a nursing diagnosis, not a collaborative problem. A collaborative problem involves potential complications that require both nursing and medical interventions. In this case, impaired physical mobility is a nursing diagnosis that requires nursing interventions to address the patient's inability to ambulate. Choices A, B, and D are incorrect because they are all relevant components of a nursing diagnostic statement: A - Etiology identifies the cause of the nursing diagnosis, B - Nursing diagnosis states the health problem, and D - Defining characteristic provides evidence supporting the nursing diagnosis.

Correct Answer: C

Rationale: The correct answer is C. The nurse can infer that the patient is apprehensive about discharge based on the subjective data of the patient expressing fear of going home and being alone. This indicates the patient may not feel ready to leave the hospital setting. Choice A is incorrect because the patient's fear of going home suggests they may not be comfortable performing dressing changes alone. Choice B is incorrect because there is no information provided to support that the patient can begin retaking all previous medications. Choice D is incorrect as there is no indication that the fear of going home is related to the success of the surgery.

Correct Answer: C

Rationale: The correct answer is C: Wear gloves for blood/body fluid contact. This is the most appropriate action for infection control when caring for a patient with AIDS because HIV is primarily transmitted through blood and certain body fluids. Wearing gloves when coming into contact with blood or body fluids reduces the risk of transmission. Explanation for why other choices are incorrect: A: Wearing gloves at all times may not be necessary and can lead to unnecessary waste of resources. B: Wearing gown and mask at all times is excessive and not indicated unless there is a risk of exposure to blood or body fluids. D: Wearing a mask during patient contact times is not necessary unless there is a risk of exposure to respiratory secretions.

Correct Answer: B

Rationale: The correct answer is B (10-15 mmHg) because this range is considered safe and effective for suctioning in most cases. Lower suction pressures (such as 2-5 mmHg) may not effectively clear secretions, while higher pressures (20-25 mmHg) can cause tissue damage. Choice C (5-10 mmHg) falls within the safe range but may not provide enough suction for effective clearance. Therefore, the optimal suction pressure for James using the portable suction unit at home is 10-15 mmHg.
