A nurse is preparing to administer cefadroxil oral suspension to a client. The available concentration is cefadroxil 250 mg/5 mL. Which of the following actions should the nurse take first?
Verify the prescribed dose with the provider.
Shake the medication bottle thoroughly.
Measure the dose using a calibrated syringe.
Check the client’s allergy history.
The Correct Answer is D
Choice A reason: Verifying the dose with the provider ensures accuracy but is secondary to safety checks. Cefadroxil, a cephalosporin, can cause allergic reactions, and unverified doses may lead to errors, but checking allergies first prevents life-threatening anaphylaxis, prioritizing patient safety before confirming dosage accuracy.
Choice B reason: Shaking the cefadroxil suspension ensures uniform drug distribution, as particles settle in liquid formulations. This ensures accurate dosing but is not the first step, as administering to an allergic client risks severe immune responses, making allergy history verification the priority to ensure safety.
Choice C reason: Measuring with a calibrated syringe ensures precise dosing of cefadroxil, critical for therapeutic efficacy. However, this follows safety checks, as administering to an allergic client risks anaphylaxis, a rapid immune response involving histamine release, making allergy history verification the critical first step before measurement.
Choice D reason: Checking allergy history is the first step, as cefadroxil, a cephalosporin, may cause anaphylaxis in penicillin-allergic clients due to cross-reactivity. Allergic reactions involve immunoglobulin E-mediated histamine release, causing bronchospasm or hypotension. Verifying allergies prevents life-threatening reactions, ensuring safe administration before other steps like dosing or shaking.

Correct Answer is C
Explanation
Choice A reason: Palliative care is not limited to hospitals; it is provided in various settings, including home or outpatient clinics, focusing on symptom relief and quality of life. It addresses pain, nausea, or emotional distress, engaging neural pathways to reduce suffering, regardless of care location or disease stage.
Choice B reason: Palliative care complements chemotherapy by managing side effects like nausea or pain, improving quality of life. It does not interfere with cancer treatment, as it targets symptom relief through medications or counseling, supporting patients’ physical and emotional well-being during active therapies like chemotherapy.
Choice C reason: Palliative care is not limited to terminal illness; it supports patients with serious conditions (e.g., cancer, heart failure) at any stage. It reduces symptoms like pain or dyspnea, enhancing quality of life via pharmacological and psychological interventions, addressing physical and emotional distress across disease trajectories.
Choice D reason: Palliative care does not replace other treatments but complements them, focusing on symptom management and quality of life. It integrates with curative therapies, using medications or counseling to alleviate suffering, supporting patients’ physiological and psychological needs without halting disease-specific treatments like surgery or chemotherapy.
Correct Answer is B
Explanation
Choice A reason: Physiological stressors, like infections or injuries, directly disrupt homeostasis (e.g., increasing cortisol via hypothalamic-pituitary-adrenal axis activation). Stress without a specified physical cause (e.g., pain, hypoxia) is more likely psychological, as the client’s symptoms suggest emotional or cognitive distress, not a direct physiological insult.
Choice B reason: Psychological stressors, such as anxiety or emotional distress, activate the amygdala and hypothalamic-pituitary-adrenal axis, increasing cortisol and catecholamines, leading to stress symptoms like elevated heart rate or impaired concentration. Without physical injury or illness specified, the client’s stress aligns with psychological causes, affecting mental health.
Choice C reason: Environmental stressors (e.g., noise, crowding) trigger stress via sensory overload, engaging the sympathetic nervous system. Without specific environmental cues in the scenario, the client’s stress is more likely psychological, as emotional or cognitive factors are common in unspecified stress presentations, not external environmental triggers.
Choice D reason: Occupational stressors, like work pressure, activate stress responses via cortisol and sympathetic activation, affecting cardiovascular and mental health. Without work-related context, the client’s stress is more likely psychological, stemming from internal emotional or cognitive factors, not specific job-related demands or workplace conditions.
