Correct Answer: C

Rationale: The correct answer is C because antihistamines can suppress the immune response that the skin test is designed to detect, leading to false negative results. By inhibiting the body's allergic response, antihistamines can mask the presence of an allergy, giving the false impression that the individual is not allergic to a particular substance. This can lead to misdiagnosis and improper treatment. Choices A, B, and D are incorrect because antihistamines do not affect bleeding, aggravate allergic reactions, or cause wheezing in the context of a skin test.

Correct Answer: D

Rationale: The correct answer is D: The patient is able to ambulate 25 feet without pain. This outcome indicates successful plan implementation for impaired mobility due to nerve compression. Ambulating without pain shows improved mobility and nerve compression relief. Choices A, B, and C do not directly address mobility improvement. Choice A focuses on pain level, which is important but not a direct measure of mobility. Choice B refers to upper extremities, not the lower extremities affected by lumbar disk herniation. Choice C addresses medication management, not mobility improvement.

Correct Answer: B

Rationale: The correct answer is B because the patient being able to ambulate in the hallway with crutches indicates that the expected outcome of improved physical mobility due to the fractured leg has been met. This demonstrates progress towards independence and recovery. A is incorrect because the patient still requires assistance, indicating dependency. C is incorrect because denial of pain does not necessarily indicate improved physical mobility. D is incorrect because it is too general and does not directly show achievement of the specific goal related to physical mobility.

Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to reflect on their own thoughts and identify potential causes of their fatigue. It allows the patient to express their own insights and helps the nurse understand the underlying reasons for the fatigue. Choice A focuses on stress, which may not be the main cause of fatigue. Choice C is irrelevant to exploring the fatigue further. Choice D assumes that lack of sleep is the main issue, which may not be the case for the patient.

Correct Answer: A

Rationale: The correct answer is A: Assessment. In this scenario, the nurse failed to assess the patient's condition promptly after being informed of feeling dizzy and light-headed. Assessment involves collecting data to identify actual or potential health problems. By not promptly assessing the patient's worsening condition, the nurse missed an essential step in the nursing process. Choice B: Diagnosis comes after assessment and involves identifying the patient's health problems based on collected data. Choice C: Implementation is the phase where the nurse carries out the plan of care. Choice D: Evaluation occurs after implementation to determine if the interventions were effective.
