The nurse is reviewing a patient’s plan of care, which includes the nursing diagnostic statement, Impaired physical mobility related to tibial fracture as evidenced by patient’s inability to ambulate. Which part of the diagnostic statement does the nurse need to revise?

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: 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 nurse should explain that zidovudine (AZT) works by blocking reverse transcriptase, the enzyme necessary for HIV replication. This is the key mechanism of action for AZT in managing HIV. Choice A is incorrect because it provides a partial truth - it does slow the disease process but does not provide the mechanism of action. Choice C is incorrect as it provides incorrect information that there are no medications to stop or cure HIV, which is not true. Choice D is incorrect as it provides misleading information about the drug becoming immune to HIV, which is not the primary concern in this context.

Correct Answer: A

Rationale: The correct answer is A: Balance. Loss of ability in balance can indicate neurological, musculoskeletal, or sensory issues affecting mobility. Speech (B) is related to communication, judgment (C) to decision-making, and endurance (D) to stamina, not specifically to loss of ability. Balance is crucial for mobility and overall function, making it a priority area for assessment in healthcare settings.

Correct Answer: D

Rationale: The correct answer is D, decreased body temperature and cold intolerance, because these are classic signs of hypothyroidism due to decreased thyroid hormone levels. The body's metabolism slows down, leading to a lower core body temperature and reduced ability to tolerate cold. Exophthalmos and conjunctival redness (choice A) are associated with hyperthyroidism. Flushed, warm, moist skin (choice B) is indicative of hyperthyroidism as well, due to increased metabolic rate. A systolic murmur at the left sternal border (choice C) is not a common finding in hypothyroidism.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.

Correct Answer: A

Rationale: The correct answer is A because determining whether an intervention is correct and appropriate for the given situation indicates critical thinking in nursing care implementation. This involves assessing the patient's needs, analyzing the situation, and using evidence-based practice to make informed decisions. This process ensures that interventions are tailored to individual patient needs and promotes safe and effective care delivery. Option B is incorrect because performing a procedure without clinical competency can jeopardize patient safety and is not an example of critical thinking. Option C is incorrect as establishing goals without assessment lacks a foundation in data and may lead to inappropriate care planning. Option D is incorrect as evaluating the effectiveness of interventions is a part of the nursing process but does not specifically demonstrate critical thinking in implementation.

Correct Answer: B

Rationale: Step-by-step rationale: 1. In a Romberg test, the patient stands with feet together and eyes closed to assess proprioception. 2. Swaying, losing balance, or arm drifting indicates impaired proprioception, suggesting a positive Romberg sign, which is abnormal. 3. Hypotension (choice A) is not directly related to the Romberg test. 4. Sneezing and wheezing (choice C) are unrelated to the test. 5. Excessive cerumen in the outer ear (choice D) does not affect proprioception. Summary: Choice B is correct as it directly relates to impaired proprioception, which is abnormal in a Romberg test. Choices A, C, and D are incorrect as they are unrelated to the purpose of the test.

Correct Answer: C

Rationale: Rationale: C: 0.25 mg is the correct daily dosage of Digoxin for adults with heart failure. This dosage is within the usual range of 0.125-0.25 mg. It helps improve heart function and manage heart failure symptoms. A: 0.005 mg is too low and ineffective. B: 0.025 mg is also too low for therapeutic effect. D: 2.5 mg is too high and may lead to toxicity in most adult patients.
