The nurse is caring for a patient in the operating suite who is experiencing hypercarbia, tachypnea, tachycardia, premature ventricular contractions, and muscle rigidity. The nurse suspects that this patient may be experiencing

Correct Answer: B

Rationale: Malignant hyperthermia, a rare anesthesia complication, matches these symptoms hypercarbia (elevated CO2), tachypnea, tachycardia, PVCs, and muscle rigidity triggered by agents like succinylcholine. It's a hypermetabolic crisis requiring urgent dantrolene. Hypoxia shows low oxygen, not CO2 rise. Fluid imbalance lacks rigidity, presenting volume-related signs. Hemorrhage causes tachycardia but not rigidity or hypercarbia blood loss is key. The nurse's suspicion drives immediate action, aligning with protocols to reverse this life-threatening state intraoperatively.

Correct Answer: B

Rationale: Aseptic technique refers to practices designed to prevent contamination by pathogens, maintaining a sterile environment during procedures like surgery or lab work. 'Contamination with infective agents are prevented,' is correct because it captures the essence of asepsis, as outlined in infection control guidelines (e.g., CDC standards), focusing on keeping sterile fields free of microbes. 'Microorganisms are destroyed,' describes sterilization, not asepsis, which prevents rather than eliminates. 'The growth of microorganism is inhibited,' relates to antisepsis or bacteriostatic methods, not the preventive focus of aseptic technique. 'Microorganisms are cultured,' is the opposite, involving intentional growth. Aseptic technique's proactive prevention of contamination, such as using sterile gloves or tools, distinguishes it from destructive or growth-related processes, making B the accurate answer.

Correct Answer: D

Rationale: Multimedia refers to data integrating multiple forms, such as voice (audio), pictures (images), and motion (video). 'Multimedia,' is correct because it encompasses all these elements, as defined in media studies (e.g., Chapman's Digital Multimedia), used in applications like video conferencing. 'Audio,' is sound alone. 'Video,' includes motion and visuals but typically excludes standalone voice. 'Picture,' is static images only. Multimedia's comprehensive nature, combining these distinct media types into a cohesive experience, distinguishes it, making D the precise answer for data with voice, picture, and motion together.

Correct Answer: C

Rationale: In everyday language, injection' broadly refers to delivering a drug via a needle, encompassing various routes. 'Parenteral,' is correct because it's the umbrella term for all injections (bypassing the gut), including intramuscular, subcutaneous, and intravenous, as per pharmacology texts (e.g., Katzung). 'Intramuscular,' and 'Intravenous,' are specific routes, not the general term. 'Subcutaneous,' is another specific method. Parenteral's broad usage in healthcare—covering any needle-based administration—makes it the common parlance for injection,' distinguishing C as the accurate answer over narrower options.

Correct Answer: B

Rationale: Premedication before anesthesia aims to optimize patient condition. 'To attenuate vagal responses,' is correct because drugs like atropine reduce vagal-induced bradycardia or secretions, per anesthesiology standards (e.g., Stoelting's Pharmacology). 'To increase volume of gastric content,' is false; it's minimized to prevent aspiration. 'To stimulate secretions,' is incorrect; drying secretions is preferred. 'To increase fear and anxiety,' opposes premedication's anxiolytic goal (e.g., midazolam). Attenuating vagal responses enhances safety, making B the accurate answer.
