Correct Answer: D

Rationale: The correct answer is D: Turn off the antibiotic. This should be the nurse's first action because in an anaphylactic reaction, stopping the administration of the causative agent is crucial to prevent further harm. Continuing the antibiotic (Choice B) can worsen the reaction. Calling the doctor (Choice A) may cause a delay in the immediate intervention needed. Calling for help (Choice C) is important but turning off the antibiotic takes precedence to stop the allergen.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Laryngeal cancer is strongly linked to smoking and alcohol consumption. 2. Both smoking and alcohol use are modifiable risk factors, meaning they can be prevented. 3. By avoiding smoking and excessive alcohol intake, individuals can significantly reduce their risk of developing laryngeal cancer. 4. Therefore, laryngeal cancer is considered one of the most preventable types of cancer. Summary of why the other choices are incorrect: B. Inhaling polluted air can be a risk factor for laryngeal cancer, so this statement is inaccurate. C. Laryngeal cancer occurs more frequently in men than women, so this statement is incorrect. D. Squamous cell carcinoma, not adenocarcinoma, is the most common type of laryngeal cancer, making this statement incorrect.

Correct Answer: D

Rationale: The correct answer is D: Ineffective tissue perfusion: Cerebral, cardiopulmonary, GI. Thrombocytopenia is a low platelet count, which can lead to impaired blood clotting and potential bleeding. Ineffective tissue perfusion is the most critical concern as it can lead to life-threatening complications like hemorrhage. Activity intolerance, impaired tissue integrity, and impaired oral mucous membranes are important but do not pose an immediate threat to the client's life compared to the risk of hemorrhage from thrombocytopenia.

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: 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.
