1. A client with a tracheostomy is exhibiting signs of respiratory distress. What should the nurse do first?
- A. Notify the healthcare provider
- B. Suction the tracheostomy
- C. Administer a bronchodilator
- D. Increase the oxygen flow rate
Correct answer: B
Rationale: When a client with a tracheostomy is experiencing respiratory distress, the priority action is to suction the tracheostomy to clear the airway and improve breathing. This helps remove secretions or blockages that may be causing the distress. Notifying the healthcare provider (Choice A) can be done after ensuring immediate airway clearance. Administering a bronchodilator (Choice C) would not address the primary issue of airway clearance in a tracheostomy patient. Increasing the oxygen flow rate (Choice D) may be necessary but should come after ensuring the airway is clear.
2. A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?
- A. International normalized ratio (INR) of 2.5
- B. Platelet count of 180,000/mm³
- C. Prothrombin time (PT) of 12 seconds
- D. Partial thromboplastin time (PTT) of 30 seconds
Correct answer: C
Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.
3. A client is postoperative following hip replacement surgery. Which of the following instructions should the nurse include in preventing dislocation of the prosthesis?
- A. Cross your legs at the knees
- B. Avoid bending your hip more than 90 degrees
- C. Sit with your legs elevated
- D. Avoid placing a pillow under your knees
Correct answer: B
Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.
4. What are the primary causes of respiratory acidosis?
- A. Hypoventilation and lung disease
- B. Hyperventilation and pneumonia
- C. Increased oxygen saturation and tachypnea
- D. Dehydration and hypoxia
Correct answer: A
Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
5. A client with newly diagnosed type I diabetes mellitus is being seen by the home health nurse. The physician orders include: 1,200-calorie ADA diet, 15 units of NPH insulin before breakfast, and check blood sugar qid. When the nurse visits the client at 5 PM, the nurse observes the man performing a blood sugar analysis. The result is 50 mg/dL. The nurse would expect the client to be
- A. Confused with cold, clammy skin and a pulse of 110
- B. Lethargic with hot, dry skin and rapid, deep respirations
- C. Alert and cooperative with a BP of 130/80 and respirations of 12
- D. Short of breath, with distended neck veins and a bounding pulse of 96
Correct answer: A
Rationale: The correct answer is A. Low blood sugar levels (50 mg/dL) typically cause confusion, cold clammy skin, and an increased pulse (tachycardia). Option A correctly describes the expected symptoms of hypoglycemia, which include confusion due to the brain's inadequate glucose supply, cold and clammy skin due to sympathetic nervous system activation, and an increased pulse (110 bpm) as the body reacts to low blood sugar levels. Options B, C, and D describe symptoms that are not typically associated with hypoglycemia. Lethargy, hot dry skin, rapid deep respirations, normal vital signs, shortness of breath, distended neck veins, and bounding pulse are more indicative of other conditions or normal physiological responses, not hypoglycemia.
