Question 1 of 5
An ABG analysis report shows: pH-7.20; PCO2-35 mmHg; HCO3-20 mEq/L. These findings are suggestive of
Correct Answer: A
Rationale: ABG values show low pH (7.20, acidotic), normal PCO2 (35 mmHg, respiratory normal), and low HCO3 (20 mEq/L, metabolic loss). This indicates metabolic acidosis, like from diarrhea or ketoacidosis, where bicarbonate drops, uncompensated by respiration. Alkalosis has high pH, respiratory issues alter PCO2. Nurses correct the cause (e.g., fluids), restoring balance to prevent cellular dysfunction.
Question 2 of 5
Utilizing critical thinking during assessment allows the nurse to:
Correct Answer: B
Rationale: Critical thinking during assessment enables the nurse to direct it meaningfully and purposefully, analyzing data as it's gathered to focus on relevant areas e.g., probing shortness of breath to uncover asthma triggers. This ensures efficiency and relevance, avoiding aimless data collection. Reviewing with providers happens post-assessment, not during, and isn't its direction. Determining care delivered is planning/implementation, not assessment's role, which collects data first. Identifying anticipated responses aligns with evaluation, not the initial data-gathering phase. Critical thinking sharpens assessment's focus, prioritizing key findings (e.g., abnormal vitals), making it purposeful and driving subsequent care decisions effectively, a hallmark of skilled nursing practice.
Question 3 of 5
A nurse wears a gown when:
Correct Answer: D
Rationale: A nurse wears a gown primarily when the patient's blood or body fluids may contaminate their clothing, adhering to standard precautions for infection control. This protects against pathogens e.g., during wound care or childbirth reducing transmission risk. Poor hygiene might prompt gloves or masks, but gowns target fluid exposure, not general cleanliness. Medication administration rarely involves fluid splash unless invasive (e.g., IV), not routine enough for gowns. AIDS alone doesn't mandate gowns unless fluid exposure is likely precautions are universal, not disease-specific. Fluid contact is the key trigger, as per CDC guidelines, ensuring nurse safety and preventing cross-contamination, making this the most precise scenario for gown use in clinical practice.
Question 4 of 5
A client who is unconscious needs frequent mouth care. When performing mouth care, the best position of a client is:
Correct Answer: B
Rationale: Side-lying prevents aspiration in an unconscious client during mouth care.
Question 5 of 5
A client complains difficulty of swallowing when the nurse tries to administer capsule medication. Which of the following measures should the nurse do?
Correct Answer: C
Rationale: Checking for a liquid form is the safest, least invasive option for dysphagia.
