When assessing a client with left-sided heart failure, which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Monitor the client's urine output.
- C. Administer a loop diuretic as prescribed.
- D. Administer morphine as prescribed.
Correct Answer: A
Rationale: Administering oxygen therapy is the initial intervention for a client with left-sided heart failure. This action is crucial in improving oxygen levels and reducing pulmonary congestion. Monitoring urine output is important for assessing renal function in heart failure, but it is not the priority over ensuring adequate oxygenation. Administering loop diuretics helps manage fluid overload but should come after addressing oxygen needs. Morphine may be indicated for pain or anxiety in some cases, but it is not the primary intervention for left-sided heart failure.

The nurse is caring for a client who is postoperative following a thyroidectomy. Which finding requires immediate intervention?
- A. Hoarse voice
- B. Slight difficulty swallowing
- C. Positive Chvostek's sign
- D. Pain at the incision site
Correct Answer: C
Rationale: A positive Chvostek's sign indicates hypocalcemia, a common complication following thyroidectomy due to inadvertent parathyroid gland injury. Immediate intervention is needed to prevent severe hypocalcemia symptoms like tetany, seizures, and laryngospasm. Hoarse voice and slight difficulty swallowing are expected post-thyroidectomy and do not require immediate intervention. Pain at the incision site is common postoperatively and can be managed with appropriate pain relief measures.
The nurse is caring for a client with a chest tube following a pneumothorax. Which finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Drainage of 50 ml per hour
Correct Answer: C
Rationale: Subcutaneous emphysema is the most critical finding requiring immediate intervention in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, which can lead to respiratory compromise. Oxygen saturation of 94% is slightly low but may not require immediate intervention. Crepitus around the insertion site can be a normal finding post-procedure. Drainage of 50 ml per hour is within the expected range for a chest tube output and does not indicate an immediate concern.
A female client who is admitted to the mental health unit for opiate dependency is receiving clonidine 0.1 mg PO for withdrawal symptoms. The client begins to complain of feeling nervous and tells the nurse that her bones are itching. Which finding should the nurse identify as a contraindication for administering the medication?
- A. Blood pressure 90/76 mm Hg.
- B. Heart rate of 85 bpm.
- C. Respiratory rate of 20 breaths/minute.
- D. Temperature of 99°F (37.2°C).
Correct Answer: A
Rationale: Clonidine can lower blood pressure, so a BP of 90/76 mm Hg may indicate that it is unsafe to administer another dose. In this situation, the low blood pressure reading indicates that the client is already experiencing hypotension, which is a common side effect of clonidine. Administering more clonidine could further lower the blood pressure, leading to potential complications. The heart rate, respiratory rate, and temperature are within normal limits and do not serve as contraindications for administering clonidine in this scenario.
A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?
- A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
- B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
- C. The additive effect of multiple medications has caused the blood pressure to drop too low.
- D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.
Correct Answer: C
Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.
The nurse is assessing the thorax and lungs of a client who is experiencing respiratory difficulty. Which finding is most indicative of respiratory distress?
- A. Contractions of the sternocleidomastoid muscle.
- B. Respiratory rate of 20 breaths/min
- C. Downward movement of diaphragm with inspiration
- D. A pulse oximetry reading of SpO2 95%
Correct Answer: A
Rationale: The correct answer is A: Contractions of the sternocleidomastoid muscle. Contractions of the sternocleidomastoid muscle suggest that the client is using accessory muscles to breathe, which is a clear sign of respiratory distress. This finding indicates that the client is working harder to breathe, typically seen in conditions like asthma, COPD, or respiratory failure. Choices B, C, and D are not the most indicative of respiratory distress. A respiratory rate of 20 breaths/min falls within the normal range. Downward movement of the diaphragm with inspiration is a normal finding indicating effective diaphragmatic breathing. A pulse oximetry reading of SpO2 95% is within the normal range and does not necessarily indicate respiratory distress.
