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.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying potential complications that may arise due to the client's health issue. This is important for developing effective interventions to prevent or manage these complications. Choice A focuses on the client's problem itself, not on potential complications. Choice C is related to nursing diagnosis, not collaborative problems. Choice D refers to medical diagnosis, which is different from collaborative problems involving nursing and other healthcare disciplines. Therefore, B is the correct focus for a diagnostic statement in a collaborative problem scenario.

Correct Answer: C

Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This inference is based on the patient's subjective feelings and concerns, which are important to address for a safe discharge. Choices A and B are incorrect as they assume the patient's readiness for independent tasks without considering their emotional state. Choice D is incorrect as there is no objective data provided to support the assumption that the surgery was not successful. It is important for the nurse to acknowledge and address the patient's emotional needs before discharge.

Correct Answer: B

Rationale: The correct answer is B: Pathologic bone fractures. In multiple myeloma, there is an increase in osteoclast activity leading to bone destruction, making patients prone to pathologic fractures. Chronic liver failure (A), acute heart failure (C), and hypoxemia (D) are not directly associated with multiple myeloma pathophysiology. This highlights the importance of understanding the disease process to determine the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Nystagmus. A phenytoin blood level of 35 mcg/ml is above the therapeutic range (usually 10-20 mcg/ml). Excessive levels can lead to symptoms such as nystagmus, which is an involuntary eye movement commonly seen with phenytoin toxicity. Nystagmus is a known side effect of phenytoin overdose. Choices B and C are incorrect because a level of 35 mcg/ml is not within the normal therapeutic range, so symptoms would be expected. Choice D, Slurred speech, is not typically associated with phenytoin toxicity.
