Galen College NU 185 Exam 1 (pdf) | 2026/2027 | Medical - Surgical Nursing II Q&A | Nursing 1. A nurse is caring for a patient with a potassium level of 6.2 mEq/L. Which medication should the nurse anticipate administering to lower the potassium level immediately? A) Furosemide B) Spironolactone C) Sodium polystyrene sulfonate (Kayexalate) D) Calcium gluconate Correct Answer: Sodium polystyrene sulfonate (Kayexalate) Rationale: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestine, promoting potassium excretion. Furosemide may also lower potassium but is not the immediate treatment for seve re hyperkalemia. Spironolactone is a potassium - sparing diuretic that would worsen hyperkalemia. Calcium gluconate stabilizes cardiac membranes but does not lower serum potassium levels. 2. A patient displays a positive Chvostek's sign. Which electrolyte imbalance does the nurse suspect? A) Hypermagnesemia B) Hyperkalemia C) Hyponatremia D) Hypocalcemia Correct Answer: Hypocalcemia Rationale: Chvostek's sign is facial twitching elicited by tapping the facial nerve, a classic indicator of hypocalcemia. Hypermagnesemia and hyperkalemia do not produce this specific sign. Hyponatremia presents with confusion, seizures, and muscle cramps rather than facial nerve hyperexcitability. Therefore, hypocalcemia is the correct electrolyte imbalance associated with this assessment finding. 3. An arterial blood gas result shows pH 7.31, PaCO2 50 mmHg, and HCO3 24 mEq/L. How should the nurse interpret this? A) Metabolic Acidosis

B) Respiratory Acidosis C) Metabolic Alkalosis D) Respiratory Alkalosis Correct Answer: Respiratory Acidosis Rationale: A pH below 7.35 indicates acidosis, and an elevated PaCO2 above 45 mmHg indicates a respiratory cause. The normal bicarbonate level suggests no metabolic compensation has occurred. Respiratory acidosis results from hypoventilation, leading to ca rbon dioxide retention. Metabolic acidosis would present with low bicarbonate, while alkalosis would show an elevated pH. 4. Which of the following is a primary cause of metabolic alkalosis? A) Severe diarrhea B) Prolonged vomiting or NG suctioning C) Hyperventilation D) Renal failure Correct Answer: Prolonged vomiting or NG suctioning Rationale: Loss of gastric acid through vomiting or nasogastric suctioning leads to an excess of base in the body, causing metabolic alkalosis. Severe diarrhea causes metabolic acidosis due to bicarbonate loss. Hyperventilation causes respiratory alkalosis by blowing off carbon dioxide. Renal failure typically causes metabolic acidosis due to impaired acid excretion and bicarbonate retention. 5. Who is responsible for obtaining the patient's informed consent for a surgical procedure? A) The circulating nurse B) The scrub technician C) The surgeon D) The nurse manager Correct Answer: The surgeon Rationale: It is the surgeon's legal responsibility to explain the procedure, risks, benefits, and alternatives to obtain informed consent. The circulating nurse may witness the consent but does

not obtain it. The scrub technician assists during surgery but has no role in consent. The nurse manager oversees unit operations and is not responsible for obtaining surgical consent. 6. A patient is scheduled for surgery and has a history of Malignant Hyperthermia. Which medication must be available in the operating room? A) Atropine B) Dantrolene sodium C) Epinephrine D) Succinylcholine Correct Answer: Dantrolene sodium Rationale: Dantrolene is the skeletal muscle relaxant used specifically to treat Malignant Hyperthermia, a life - threatening reaction to certain anesthetic agents. Atropine treats bradycardia but is not used for Malignant Hyperthermia. Epinephrine is used f or anaphylaxis, not Malignant Hyperthermia. Succinylcholine is actually a triggering agent for Malignant Hyperthermia and must be avoided. 7. What is the first nursing action when a patient's surgical wound eviscerates? A) Push the organs back into the abdomen B) Call the family to provide support C) Cover the protruding organs with sterile gauze soaked in normal saline D) Instruct the patient to cough and deep breathe Correct Answer: Cover the protruding organs with sterile gauze soaked in normal saline Rationale: Evisceration requires immediate covering with sterile, saline - soaked dressings to keep organs moist and protect them from infection while waiting for emergency surgery. Pushing organs back into the abdomen is never appropriate and risks further injury. Calling family does not address the immediate emergency. Coughing and deep breathing would increase intra - abdominal pressure and worsen the evisceration. 8. Using the Rule of Nines, calculate the percentage of burn for an adult with burns on the entire left arm and the anterior trunk. A) 18% B) 27%
