Nokea
When performing a neurologic assessment on Ken, the physician notices that there is contraction of his facial muscle after tapping the facial nerve anterior to his ear. He recognizes this as Chvostek’s sign. This is seen in:
- A. Hyponatremia.
- B. Hypokalemia.
- C. Hypocalcemia.
- D. Hypomagnesemia.
Correct Answer: C
Rationale: The correct answer is Hypocalcemia (C). Chvostek's sign is a clinical sign of hypocalcemia, where tapping the facial nerve causes twitching of facial muscles due to increased neuromuscular excitability caused by low calcium levels.

If a client’s parathyroid glands were accidentally removed during a procedure, which condition should the nurse prepare for?
- A. Hypomagnesemia
- B. Hyperkalemia
- C. Hypernatremia
- D. Hypocalcemia
Correct Answer: D
Rationale: Parathyroid glands regulate calcium levels. Their removal leads to hypocalcemia due to decreased parathyroid hormone production.
A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct Answer: A
Rationale: The correct answer is A: Respiratory acidosis. Shallow respirations at 9/min indicate hypoventilation, leading to retention of CO2 and respiratory acidosis. This is because inadequate removal of CO2 results in an increase in carbonic acid concentration, leading to a decrease in blood pH. Respiratory alkalosis (B) is unlikely with shallow respirations. Metabolic acidosis (C) results from nonrespiratory factors. Metabolic alkalosis (D) is not related to respiratory rate.
A client with respiratory failure is receiving mechanical ventilation and continues to produce ABG results indicating respiratory acidosis. Which action should you expect to correct this problem?
- A. Increase the ventilator rate from 6 to 10 per minute
- B. Decrease the ventilator rate from 10 to 6 per minute
- C. Increase the oxygen concentration from 30% to 40%
- D. Decrease the oxygen concentration from 40% to 30%
Correct Answer: A
Rationale: Increasing the ventilator rate enhances CO2 removal, correcting respiratory acidosis by improving ventilation.
A client who will undergo a bronchoscopy procedure with a rigid scope and general anesthesia will have their neck in which of the following positions?
- A. A flexed position
- B. An extended position
- C. A neutral position
- D. A hyperextended position
Correct Answer: D
Rationale: The correct answer is D: A hyperextended position. During bronchoscopy with a rigid scope, the client's neck needs to be hyperextended to facilitate optimal insertion of the scope into the trachea. Hyperextension straightens and opens up the airway, providing better visualization and access to the bronchial tree.
Choice A (flexed position) would obstruct the airway and make insertion difficult. Choice B (extended position) would not provide the necessary alignment for scope insertion. Choice C (neutral position) may not offer sufficient airway visibility and access.
In summary, a hyperextended position is crucial for successful bronchoscopy with a rigid scope, as it ensures proper alignment, airway visibility, and scope insertion.
Joan has osteoporosis. She has an increased risk for
- A. Infection in the bone.
- B. Peripheral blood clot formation.
- C. Fracture formation.
- D. Painful joint inflammation.
Correct Answer: C
Rationale: Osteoporosis weakens bones, increasing the risk of fractures.
