Questions, Answers & Detailed Explanations
1. Diphenhydramine Administration
• Question: What is diphenhydramine, and how is it typically administered
in acute care?
• Answer: Diphenhydramine is an antihistamine commonly administered as
20 mg orally.
• Explanation: Diphenhydramine acts by blocking histamine receptors to
alleviate allergic reactions, pruritus, and anaphylactic symptoms. Oral
delivery is suitable for mild reactions, while intravenous or intramuscular
routes are prioritized for acute, severe distress.
2. Cefoxitin Dosage
• Question: What classification does cefoxitin belong to, and how is
pediatric dosing calculated?
• Answer: Cefoxitin is a second-generation cephalosporin antibiotic
prescribed at 80 mg/kg/day.
• Explanation: Antibiotic weight-based dosing ensures therapeutic plasma
concentrations while minimizing systemic toxicity risks. The total daily
, dosage is generally divided into equal intervals (e.g., every 6 to 8 hours) as
ordered.
3. Intravenous Pump Utility
• Question: What is the primary function of an intravenous (IV) pump in
clinical settings?
• Answer: An IV pump is an automated mechanical device utilized for safely
administering intravenous fluids and medications.
• Explanation: Infusion pumps regulate precise flow rates (mL/hr),
preventing accidental fluid overload or under-infusion, and include safety
alarms for air-in-line and occlusions.
4. Serum Albumin and Wound Healing
• Question: What does a low serum albumin level indicate regarding tissue
integrity?
• Answer: Serum albumin is a major plasma protein level whose deficit
indicates a high risk for impaired wound healing.
• Explanation: Albumin reflects visceral protein status and oncotic pressure.
Malnourished or depleted protein levels compromise collagen synthesis,
cellular proliferation, and immune response, delaying recovery.
5. Blood Pressure Cuff Dimensions
• Question: What proportion of a client's arm circumference should a
proper blood pressure cuff bladder encompass?
• Answer: The inflatable bladder of the blood pressure cuff should be 40%
of the arm circumference.
• Explanation: Using an incorrect cuff size leads to erroneous readings; a
cuff that is too small produces falsely elevated pressures, while an
oversized cuff yields falsely low readings.
6. Suction Catheter Usage
• Question: What classification of device is a suction catheter used in
respiratory management?
• Answer: A suction catheter is a single-use sterile device designed for
airway management and clearance.
, • Explanation: Single-use policies prevent cross-contamination of
pathogenic bacteria into the lower respiratory tract, minimizing the
incidence of ventilator-associated or hospital-acquired pneumonia.
7. Orthostatic Hypotension Assessment
• Question: How is orthostatic hypotension clinically defined during
position changes?
• Answer: Orthostatic hypotension is characterized by a significant drop in
blood pressure occurring upon transitioning from a lying to a sitting or
standing position.
• Answer: Typically marked by a drop in systolic blood pressure of at least
20 mmHg or diastolic pressure of 10 mmHg, this condition increases fall
risks and requires gradual position changes and hydration assessments.
8. Dysphagia Interventions
• Question: What clinical presentation defines dysphagia, and what
immediate adjustments are required?
• Answer: Dysphagia refers to difficulty swallowing, which frequently
necessitates specialized diet modifications and texture changes.
• Explanation: Safe feeding protocols protect against aspiration pneumonia.
Alterations include thickened liquids, mechanical soft diets, and upright
positioning during meals.
9. Braden Scale Application
• Question: What is the purpose of the Braden Scale in nursing
assessments?
• Answer: The Braden Scale is a validated clinical tool used for assessing
pressure ulcer risk factors.
• Explanation: It evaluates six subscales: sensory perception, moisture,
activity, mobility, nutrition, and friction/shear. Lower scores indicate higher
vulnerability, prompting aggressive skin-care protocols.
10. Tracheostomy Care Protocols
• Question: What technique is mandatory when cleaning a tracheostomy
stoma?
, • Answer: Tracheostomy care requires strict adherence to sterile technique
for cleaning the stoma and surrounding skin.
• Explanation: Because the artificial airway bypasses the upper respiratory
tract's natural filtration defenses, maintaining sterility prevents bacterial
introduction directly into the trachea.
11. Enema Administration
• Question: What does effective enema administration involve for optimal
bowel clearance?
• Answer: Enema administration involves specific anatomical steps and
positioning for effective delivery of solution into the rectum.
• Explanation: Placing the client in the left lateral Sims' position allows
gravity to align the solution with the natural curve of the sigmoid colon,
maximizing evacuation efficiency.
12. IV Fluid Equipment Monitoring
• Question: What routine safety practice is required during intravenous fluid
administration?
• Answer: IV fluid administration requires continuous monitoring for
equipment defects, infiltration, and flow-rate errors.
• Explanation: Early detection of mechanical failure or localized tissue
damage prevents severe systemic complications like fluid overload or
localized necrosis.
13. Hypoxemia Identification
• Question: What physiological state does hypoxemia represent?
• Answer: Hypoxemia describes low oxygen levels circulating within the
arterial blood.
• Explanation: Manifesting as restlessness, tachypnea, and cyanosis,
hypoxemia requires immediate oxygen therapy and respiratory status re-
evaluation.
14. Atelectasis Management
• Question: What pulmonary complication involves alveolar collapse, and
how is it managed?
