Nokea
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 with a nasogastric tube in place following gastric surgery reports nausea. What is the most appropriate nursing action?
- A. Irrigate the NG tube with 30 ml of normal saline.
- B. Administer an antiemetic as prescribed.
- C. Assess the NG tube for patency and reposition if necessary.
- D. Provide sips of water and reassess the client's symptoms.
Correct Answer: C
Rationale: Assessing the NG tube for patency and repositioning it if necessary is the most appropriate action to relieve the client's nausea. Nausea in a client with a nasogastric tube can be due to the tube's malposition or blockage. Irrigating the NG tube with normal saline (Choice A) without assessing for patency or repositioning may worsen the situation. Administering an antiemetic (Choice B) can help manage symptoms but does not address the potential issue with the NG tube. Providing sips of water and reassessing symptoms (Choice D) may be contraindicated if there is a problem with the NG tube and could exacerbate the nausea.
The nurse is caring for a client with a chest tube in place following a pneumothorax. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Blood pressure of 110/70 mmHg
Correct Answer: C
Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.
The nurse is assessing a client with left-sided heart failure. Which finding requires immediate intervention?
- A. Shortness of breath
- B. Jugular venous distention
- C. Crackles in the lungs
- D. Peripheral edema
Correct Answer: C
Rationale: Crackles in the lungs indicate pulmonary congestion in a client with left-sided heart failure and require immediate intervention to prevent respiratory failure. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potentially respiratory distress. Shortness of breath, jugular venous distention, and peripheral edema are common manifestations of heart failure but do not directly indicate acute respiratory compromise like crackles in the lungs do.
A client with heart failure is prescribed furosemide (Lasix). Which assessment finding requires immediate intervention?
- A. Heart rate of 60 beats per minute
- B. Blood pressure of 100/60 mmHg
- C. Crackles in the lungs
- D. Presence of a new murmur
Correct Answer: C
Rationale: The correct answer is C. Crackles in the lungs indicate fluid overload, a common issue in heart failure patients. Immediate intervention is necessary to prevent worsening heart failure symptoms and potential complications. A heart rate of 60 beats per minute and a blood pressure of 100/60 mmHg are within normal ranges for many individuals and do not typically require immediate intervention in this context. The presence of a new murmur may be important to monitor but is not the priority when crackles in the lungs suggest fluid overload.
The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct Answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
