1. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
2. Which instruction should be included in the discharge teaching plan for a client who has had a cataract extraction today?
- A. Use a metal eye shield on the operative eye during the day.
- B. Administer eye ointment after applying eye drops.
- C. Light housekeeping is safe to do, but avoid heavy lifting.
- D. Refrain from sexual activities until follow-up appointment.
Correct answer: C
Rationale: The correct instruction to include in the discharge teaching plan for a client who has had a cataract extraction is that light housekeeping is safe to do, but heavy lifting should be avoided to prevent increased intraocular pressure. Choice A is incorrect as the eye shield is usually worn at night to protect the eye. Choice B is incorrect as eye ointment is usually applied after eye drops to avoid washing away the ointment. Choice D is incorrect as sexual activities should be avoided until the follow-up appointment to prevent complications.
3. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy at 2 liters per minute via a nasal cannula. Which assessment finding indicates a potential complication of oxygen therapy?
- A. Increased respiratory rate
- B. Decreased level of consciousness
- C. Improved oxygen saturation
- D. Complaints of dry mouth
Correct answer: B
Rationale: In clients with COPD, oxygen therapy can lead to a decrease in the respiratory drive caused by the removal of the hypoxic drive. This can result in carbon dioxide retention, leading to a decreased level of consciousness. Options A, C, and D are incorrect because an increased respiratory rate is typically a sign of hypoxia, improved oxygen saturation is a positive response to oxygen therapy, and complaints of dry mouth are not directly related to oxygen therapy complications in this scenario.
4. A young female client with 7 children is having frequent morning headaches, dizziness, and blurred vision. Her BP is 168/104. The client reports that her husband recently lost his job and she is not sleeping well. After administering a STAT dose of an antihypertensive IV med, which intervention is most important for the nurse to implement?
- A. Measure urine output hourly to assess for renal perfusion
- B. Request a prescription for pain medication
- C. Use an automated BP machine to monitor for hypotension
- D. Provide a quiet environment with low lighting
Correct answer: C
Rationale: Using an automated BP machine is crucial to continuously monitor for hypotension after administering an antihypertensive medication. This is essential to prevent a rapid drop in blood pressure that could lead to complications. Measuring urine output hourly to assess for renal perfusion is important but not the most immediate concern in this situation. Requesting pain medication is not relevant to the primary issue of managing blood pressure. Providing a quiet environment with low lighting may be beneficial for the client's overall well-being but is not as critical as monitoring for potential hypotension.
5. The parents of a child who has had a myringotomy are instructed by the nurse to place the child in which position?
- A. Supine
- B. On the affected side
- C. On the unaffected side
- D. In Trendelenburg's position
Correct answer: B
Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.
